What is Node.js considered good for?

Node.js Developer

The idea to deal with Node.js would be pretty good as compared to using Java script syntax. It’s more appropriate in building websites that need real-time, synchronous interaction. It is more essentially required by chat sites like Meebo etc.

If you are well experienced in practice on a custom framework that did this in Ruby, you could easily examine that it’s hard to get right in a language which are unfavorable for it according to satisfaction of the condition, like the core back-end infrastructure was erected around these Event Machine.

In Python Development you get the facilities of Tornado and Twisted that basically serve as the core for these sorts of servers. Thus, it became simple to set up this level of interactivity with Node.js.

Here’s some of the usefulness of Node.js which could easily valid it out to be considered good.
1. Not only it’s useful in writing HTTP, but also TCP servers. Some tiny examples with seven to fifteen lines of code represents a huge shift in paradigm of creating a server. Here you don’t need to struggle with fork or threads model and also you are escaped from suffering with mutexes, semaphores, and all other old boring locking crap.

2. Node is most helpful for those applications which hold a huge number of collections open for a long time works. It easily enables you to write programs in JavaScript.

3. To be very clear, it could be said that it is more effective at those fields where the applications requires a large number of concurrent connections active at a given point of time and needed an immediate response of time, for example, chat applications, multiplayer, games, virtual terminal emulator, etc.

4. This is the most outstanding feature of Node.js which marks it good to practice. It is a customized JavaScript based on Google V8 JavaScript. You can easily create dynamic web server in a reasonable time without waste of any time.

Its manager package has more than sixty thousands of modules which provide node.js developer a better control on development and advance on server site script. It contains a well cross-platform, which compatibility allow developer to run applications over any operating system.

These are some of the sub-fields where Node.js are considered good.

What is the best Node.js template engine?

Node.js Developers

Talking about best Node.js template engine, there are number of template engine available to use by Node.js developers. Some are discussed most concisely with regard to its developments and qualities with view to cover most of their sections.

All the templates engine available are followed by certain pros and cons, and which should more effective should to be considered according to its suitability and availability of satisfying power to achieve all those basic functions efficiently which are performed at the due course. Let’s start the discussion regarding several template engines for Node.js. The most popular and well known template engine is Jade that is similar to Html which uses white space.

To utilize the same server side templates on the front-end, jade-browser library is available. It is the reason due to which it is used at Storify. Complementing the template benchmark, jade is 2x slower than Handlebars, EJS, Underscore, etc. The functioning of ECT seemed to be relative faster.

Usually, the whitespace-strict languages, such as Python, are unfavorable as it is inclined more towards Handlebars/Moustache which seemed to be a default choice for reactive templates with web-sockets, which are Derby, Meteor frameworks etc. though it is not specific, Moustache.js is one of the simplest and versatile template engines. Still it is not so admirable and effective engine as it doesn’t allow you to run if/else and other logics in the templates.

Thus, templates remain completely as templates are driven totally be the JSON data provider. If and for loop based on the JSON data is the only implicit reason to prefer it. Otherwise there are no valid reasons available for convenience. It may also depend on the behavior that how much logic you want to put in your templates. Here we are left with no other relevant option other than to prefer logic-less templates (a Moustache engine), so Hogan is the weapon of choice. Yet we couldn’t find a good wrapper to use Hogan with Express and still get partial and layout support.

Here you can identify the comparative reason to move from Jade to Moustache. Though Jade is elegant in making a template markup, it is really a thing of beauty which is more attractive. On the other hand, Moustache is “lower-level”. It’s is really easy to just whip together the bits of html with variables interspersed, rendered with a context and to get output. Most people prefer to switch to Moustache from Jade basically because it is found faster and conceptually simple to be used it as a client-side.

You should not maintain two solutions on the server and client. Therefore it seemed to be good to shift rightward from Jade to Moustache which could be proved later to be active move. You may also like Jade syntax, but it could be little too invasive and force developers to learn something radically different from HTML.

Another fastest and passionate template engine is Dot.js.

At the same time you should also keep in mind that the fastest doesn’t always means the best, but look for the one with which you and your team may be comfortable to use. You can also use Swig on various assignments which could be seen more attractive. It is of great pleasure to work with it and the 2x version is very easy to expand. It also works both on server and client. Or you should rather stick to something which seemed to be the mainstream of the project and should opt for the one with which you are more comfortable. The mainstreams could be recognized in the ways such that the following engine is attached to its features. Like Jade is great for template aspects.

On the other hand, Coffee Kup favorable for Coffee-Script programmers. In this way you can select your template engines by combination of functions of various engines and by eliminating the less preferred one.

Which Node.js framework is good to build a RESTful api?

Node.Js Developers

For building a RESTful api, we need to focus more on the frameworks available on Node.js. You need to build a hand-made registry of Node.js framework. There are number of frameworks available in Node.js, which could be suitable for developing a RESTful api, such as Restify, Express.js, Rest MVC, WebService.js, Flatiron, Koa, Locomotive etc. basically Representational State Transfer services don’t require the presence of frameworks.

Still frameworks could be used for building a RESTful api which are all discussed below in more detailed way.

The most light-weighted and effective framework is Restify. It doesn’t needs to force a programmer to use external modules or libraries. Apart from that it functions with minimum features. This was the basic framework available in Node.js for RESTful api.

Now let’s compare both, Restify and Express, so that we could get an overall view of these framework which could me more suitable.

Other than this, there are more frameworks which could be used for it. But the basic element to be kept in mind is that the framework should satisfactory and work efficiently according to the requirement.

Another framework which is worth to be discussed is Express.js. It’s also the basic Node.js API. It contains more functionality, including especially templating and rendering and every module needed could be easily added.

Normally, Restify is considered as a framework which provides absolute control over interaction with HTTP and complete ability to observe into the latency and characteristics of your applications. On the other hand, Express.js is opposed to Restify. It can become overwhelming with time (all end points need to be created manually). We should rather list some pros and cons of these frameworks.
Express.js is most popular among the other frameworks because of its simplicity and the liberty to satisfy all the benefits of any other frameworks.

Another advantage of using it is that it could become possible to find many online tutorials other than support from the community, in case problem occurs. This is the reason for sticking to the most popular frameworks.

Next framework which you can use is Sails.js. It is commonly known and appreciated for its
flexibility and its speed which it allows building an app skeleton. It can do wonders for Node.js developers. Apart from this, it also include some other features such as, blueprints, policies, Waterline (ORM). Yet is carries from certain drawbacks which are noticeable. Since it is new, it hasn’t yet been tasted on properly.

Now let’s discuss about another framework, i.e. Hapi. It seems to provide a complete set utilities for deploying APIs and seemed to be quite promising. There are valid reasons to stick with Hapi as it builds API but not web app. There is Hapi module present for any major challenges of API building and at the same time it will also help you saving lots of time.

You should stick with Hapi because of the following reasons stated below.

1. Developed by WalmartLabs, Hapi is well and nicely maintained. They update it pretty frequently fixes lots of issues reported.
2.  It has very well developed video tutorials available on YouTube.
3. It embraces configuration cover code and containing the authentication schemes and strategies which makes it easy to plug different auth methods to separate routes.
4. It’s created for rich and robust node plugins for authentications, error handling, validation and other tasks which makes it easy to integrate. It seemed like these plugins have been developed alongside the framework development.
5. Loopback is full of opinions. It is created for faster initial developments than any other things to attain. It’s really very promising in nature.
6. Hapi has many achievements in automating basic REST API needs yet giving all the flexibilities you need. Initially you can use their own Node modules available and in future it can be easily be replaced with your own if you want. It is fine tuned for creating RESTful APIs.
Among the above discussed frameworks, you should be concerned about its pros and cons and then select the one to be used for after combining it with another frameworks.

Which server technology is better: Node.js/Express.js or Python/Django?

Node.js Developers

Different sever technology have different features which varies from one another. Moreover, Node.js developers is asynchronous which makes it outstanding and different from others. This marks the real advantage over the traditional server side environment.

Node.js/Express.js is always under the development. This asynchronicity reveals that the applications are easier to develop and it can hold better and more concurrent connections. From this point of few, it may be said that node.js/Express is better than Python/Django.

The main advantage of Node.js is that it relies on the fact that it is “asynchronous”. Other feature of Node.js is, it is very fast and it’s all Javascript.

These days, single page application is more popular, which eliminates the need for scaffolding with Rails and Django. For this reason, there is need of Express which relaxes from the use of heavy framework.

A brief review of Node.js and Django is described below:
Django

Popularity: It is popular known tool but the user community is comparatively little less than Common Rail.

Easy to learn? Excellent Documentation but slightly steeper learning curve. It requires some configuration before one get it into development.

Easy to build and iterate? It is easy to build and iterate once the operator is up and running with it.

Easy to deploy? It is easy but comparatively lesser than Rail. There are some heroku equivalents djangozoom.com, stable.io and many more; but they tend to limit in their private Beta.

Node

Popularity: It is not much popular but is gaining popularity.

Easy to learn? Well, it is not too easy nor too difficult. It always allows a quicker connection to Hello World server together but it is more tricky and complex if full scale app is required. It is new to learn and still evolving in a better way. It is not absolute to compare Node and Django; as Django is a framework and Node is a barbone set of Apis that the user can use to develop something.

Easy to build and iterate? Yes, it is easy to build and iterate.

Easy to deploy? It is easy to head on to Node and apply to get a smart machine. It is easy to deploy.

Disadvantages of developing a web application using Node.js instead of Python?

Node.js Development

One of the important thing here to decide in accepting either Node.js development or Python development rely in the personal comfort and ease with the programming language or framework. The output or the effectiveness that we expect from Django, Node.js, Tornado, CakePHP, CodeIgnitor is is to be productive.

Different people have different opinion and one of the best way to satisfy and confirm yourself is through projects. It is better to deal the practical yourself than the aired heard voices. Most of the users who operated with Node.js and Python suggest using Python instead of Node.js. It is not because Python is better than Javascript but because it allows to complete the task quickly and easily.
Here are some of the main points that makes Python more selective than Node.js:

1.    There are different challenges that the operator faces when dealing with the side wise programming and Browser programming, both of which are not just the same. One of the benefits of Node.js is that it allows the use of javascript from both the sides, front end as well as from the back end. But it is to be kept in mind, that the programming methodologies are not the same.

2.    Since Node.js is new, so lots of frameworks are not available. One has to deal with the old ones and modification is too complex. The distribution prevents the framework into it, but is more to dependent to find one and use it. The major complaint answer that the frameworks appeared to want to model after RoR which they lacked. So, it requires a learning process and would consume time.

3.    As we know, there is been an issue to limit the capacity of the memory to run in. It is 9.5 GB. The amount exceeding this capacity is difficult to deal. Many of the even driven programming model executes in a single core and be scaled horizontally by Load balancing multiple instance on same machine using a single core at a time. It do not require any memory cap when dealing with any other language. The point to think is, it can work on higher load but under extreme load it can become a brick wall. But it is necessary to balance the core and physical hardware.

We at Laitkor can always assist you in giving relevant information about developing a web application by using best of the server technology and comparative advantages and disadvantage of the apps.

What are the benefits of developing in Node.js versus Python?

Node.js Application Development

Both the aspects of web development follow from various benefits indulging some universal limitations. After going through the pros and cons of both the frameworks, you shall easily be in the position to judge which of the above you must prefer. The medium of distinction arises from reliability, working conditions, and other factors. Most of the time, Node.js overcomes other development platform, including Python too.
Here are the following points of comparison which would state the several benefits of developing either in Node.js or Python.

1.    Managing the asynchronous

The main motive behind Node.js application development is to manage asynchronous I\O from the ground up. It is Node.js that allows you enjoying outstanding features which are all pervading. While in other platforms of web development, you would be given limited choice for pieces available in async. But it is tough to write non-asynchronous code in Node.js.

2.    Limitation to JavaScript

Another point that will relate the amount of benefits you may avail through using Node.js or Python development is the efficient usage of JavaScript. This might be the basic reason for constant switching from one framework to another. Here you can save much time by minimizing syntax errors that occurs most commonly, such as, missing of braces in JavaScript, semicolons in Python, etc. But these kinds of attitude of get affected even by minor issue will not going to yield you in long term. So you should stick to the one you prefer initially and perform your task faster.

3.    Latest and modern

Since Node.js is new, you can avail the benefits of correcting yourself according to the mistakes made during previous activities, may be language or the framework. Node.js will help to in rectifying such errors without any backwards-compatibility concerns. Its outlook seemed to be very orderly organized and managed which appear as latest innovation.

4.    Experiencing

Developing with Node will always present you some reward, either in cash or kind. Apart from this you would be accumulating prompt knowledge while working with Node.js. Its outstanding features and powerful stuffs will definitely make you an expert in web development, as long as you tend to explore Node. Hence, it will help you in becoming more better and active developer. It is just a cool platform through which you can promote yourself in app development and its tools are more appropriate to be contented in your toolbox.

5.    Others

This may refer to many other subheads which individually add benefits to Node as well as Python. Like coding style, benchmark results, multiplayer gaming, etc. for networking related programming, area of development is vast. And the best part is that you can alternately use same language for both kind of development (server and client).

You must learn to work with Node as it’s very useful and will merely help you further in developing a creative web app. Similarly, JavaScript may also become a best medium for development.

We at Laitkor, provide you the best and efficient service in Node.js as well as JavaScript.

Is Node.js a better choice than Python for server side development?

Node.js Programming

From practical aspects, both Node.js and Python are a very good language to be used for server side development.  But both of them may vary in their features and the extension of their linkages to the work area. Some of the important points must be kept in mind are:

1. Python has left a long time remark of history on server and earned a lot of fame. Comparing with Node.js, Python have got more number of available tool sets, robust libraries and frameworks. These feature activates Python programming to a broader level. Python provides you a back-support for running in a multi-process, multi-threaded or event-based setup.

2. From theoretical point of view, Python may be easy to understand and learn. The programs are not too complex. For a new programmer, server side development may start with learning programs line-by-line logic. On the other side, it is difficult for the beginner to deal with Node.js programming.

3. Node.js offers a very rich open source ecosystem (Node package manager) and the ability to use libraries (like moment, underscore, Async) both on server and client side. Since we are dealing with server side development and Python is not a client language, so working with Node.js extends the scope of the learner for the front end web development.

4. Programming with great Javascript code is not so easy. It’s difficult and tricky. IoT is a rich area where Node.js stands appreciable than Python. So, as concerned with the future side of the student/learner, Node.js may be an important tool.

5. Python has a renowned fame of serving with the fast and functional data manipulator.
Node.js is looked as a fast way to exchange (send and receive) data between clients and database which may lead to user experience.

Each of the language has got some specific significance which makes them different from others. Python has got a number of features and Node.js is meant for a broader scope for the Server side development. Think to select accordingly and wisely.

We, at Laitkor are dedicated towards assisting you in providing the best of knowledge about the languages and their comparative value for Server side development. For any assistance on app development, feel free to get in touch with our expert panel at helpdesk.

Is it possible to develop a web application with node.js only without any server-side language except JavaScript?

Web Application Development

Node.js is not any language, but it is an evented I/O framework that itself uses JavaScript programming language. It is possible to build any type of web Application by using Server- side JavaScript, although some of them may interface with external process or the native codes. By using common Node packages, it is possible to write potable server- side JavaScript web application that could run on platform other than Node.js.

Here are some of the points about web application that should be considered

1. It is a common known fact that most of the users depend on Express for their work, which appears as for the kids these days. If you are thinking to work on Traditional web development, those frameworks are a great option to benefit you.

Development without using any kind of web application with node.js only, without using any server side language other than JavaScript

2. But if you are looking for a real framework, you can check out Socket.IO . It is actually the best way to do websocket on any platform or language.  Even if it will not be the best in your opinion, it would surely be the easiest.

3. If there is not a good library in Node.js, then you need to write parts of your application in any other language.

For example: image manipulation, Captcha creation and pdf generation may require another language but you may run them in a fairly easy way.

4. To answer the word “any” in the article heading, the answer is “Yes”. Since it contains a full HTTP stack letting the program to manipulate any portion of that protocol. It is amused to find that a Node program could do anything through the HTTP protocol.

5. It is too quick for producing functionality. If you are a new JavaScript user, start with Meteor else start with Express. But to be serious, you must understand to deal with both of them.

What is the most recommended node.js compatible IDE?

Node.js Development

There are many different types of IDE which are chosen as per the need of the user. Some of them may be Open source/free, Omni-complete API/snippets/ modules, improved debugging and syntax-highlighting. Different operating system can be used for different IDE’s.

Recommended node.js development compatible IDE

1. WebStorm
As an IDE, WebStorm is not free but there are programs to support OS developer and it also supports interactive debugging and syntax highlighting (using static analysis and error prediction). You may also use Notepad++, although it is not an IDE but it is very light and has syntax highlighting. Printing by Notepad++ is pretty as well. It is easy process to just open→edit→save→quick fixes.

2. Komodo Edit/IdE
It has a hinting built in node.js code and has a console from where you can work on node.js. Komodo Edit is the free and OSS version of Komodo IDE. It is a lightweight and responsive cross platform.

3. Sublime Text 2/3
It Is one of best editor, but not an IDE. If you are not looking for an IDE, this might be a great choice to select as it offers TONS of plugin.

4. Nodeclipse
It is IMO terribly, heavy and baggy with too less features than Webstorm. It has a debugger but it really don’t work much effectively.

5. Koding
It comes pre installed with node, vim, emacs and it is all in the browser. It has a lot of awesome feature and is freely available. This makes coding more impressive.

6. Light Table
It is open source and light weight IDE that works great with Git and you can also find some great plugins for Node.js and javascript in general.

Which technology is better among Golang and Node.js for server side coding?

Node.js Development

The answer to such an intriguing question cannot be easily answered in favour of either of them. It may vary among operators and depend on the purpose expected by the user. The programming languages are the tools in hand which must be operated in an efficient way for the right task. Without knowing and exploring what the user want to develop, none can answer questions of this sort.

Here are some of the important points to be kept in mind

1.    Golang (or GO) is a programming language developed at Google and prefers Go, Asm language. While Node.js is a cross-platform application written in Javascript, C, C++. So the coding varies with the language.

2.    In Node.js, it is easier to reuse codes for both server and clients which reduces the dependency to learn two different languages. This means, there is ease in performance and time saving.

3.    Node.js is single threaded software that do not permit to exploit multi-core capabilities of the working platform without switching on to multi-process virtualization.

4.    If you want to be cool and geeky, go for Golang.

5.    The callback based programming model explores Node.js as unwieldy as the program code increases. While, there is no such obstruction in the Golang language.

6.    It is difficult for the in-experienced coders to code in any of the language, but Golang may dominate the preference here probably to be more manageable.

7.   Javascript, the programming language for Node.js, is more expressive and fast. Go, which appears to be more concise and flexible than any other language, may put up heavy when the user want to deal with changing structures.

On the other hand, Golang is comparatively faster regarding the calculations.

If you want to be practical and implementing with the useful task, one must choose Node.js.
We can always assist you in providing the best of knowledge about the technology related to server side coding, and comparatively the better one for specific purpose may it be for Node.js Application Development or Go Programming. For further details contact our support team at Laitkor.

How fast is Node.js?

Node.js Developers

By default, Node.js uses asynchronous handling of events, while Java and Python uses threading by default. This is obviously not important, but higher than the apache web server which is being converted to support an async event model, it may observe a down fall anywhere from 1000-5000 concurrent connections in which many of them can be extremely long. Node.js developers are the proper maintainer and are working to increase the speed of applications.

How fast it is?

1.  The speed of JavaScript and Java is mostly irrelevant if you are not doing a huge amount of processing in JavaScript. The biggest difference will be in the event model and is the current best place in Node. It is the fastest unless you are able to write Java code with an async event model. V8 is faster than Python. You can expect Node.js to be faster even when attempting async development.

2.   You can understand this by an example:- If there are 10 servers requirement to run your Python code, your requirement for Node.js will be just 2 or 3 servers for approximately equal performance.

3.   Node uses Chrome’sV8 which is a JIT compiler. This actually makes it faster, as fast as compiling language but not reliability. However, good JITs can be very fast under right circumstances. In some cases Py-Py can be fast as C.

4.   For certain tasks, it is surely very fast. But it uses more memory even than regular VM Languages as a JIT. It is also weak at traditional concurrency due to not having it and not keeping it as an issue for server-side development. Overall, it’s very preformat for server-side development and passable for other tasks, but far from ideal for other reasons.

5.  Node.js is a framework written for JavaScript code and it is not a programming language. Node.js is the second fastest back-end tech according to benchmark. The run time for Node is written in mostly C++.

6.   It is pretty decent but not the fastest runtime out there and unless you do a lot of processing, the speed should not really matter. The single thread /async model is for another discussion entirely. You can use Node for sockets, because it is best suited for that.

It is true that Node.js is not the fastest framework but it is fairly good to fit the purpose. The chrome’s V8 is used by Node which is a JIT compiler. It uses asynchronous handling of events by default.  It is written for JavaScript code and is not a programming language.

How good is node.js?

Node.Js Developers

Node.js is the fastest framework available for Web Apps. It is really the best choice for client-facing containers in large SPA and SaaS products though it is the not the magic bullet for everything. Node.js is surely not the fastest for web pages but it is faster for Single page Apps (SPA) and Software as a Service (SaaS). As all the clients share the same event loop, Node is so fast. Node.js developers are punctual towards their assigned work of project and development which makes it a regular using framework.

Goodness of Node.js

1.    A single server can host 1,000,000 clients and all can be connected in a real time. The share is even the same as in the exact event loop, in the same exact process, on the same exact processor which means that they can all exchange messages, and more importantly, they can also share the same framework overhead and outsource blocking operations to worker thread. It indicates that node never blocks unless you are doing it wrong.

2.    It is the strength of node that it runs faster in a single thread and it should not be seen as a weakness to do this way. To scale with node, you don’t do squat at all, and then you just toss a new server into the worker thread pool. If your database access is getting slower, you can toss a new server DB server in the pool. Node handles all BS.

3.    Node is always there to stand anytime when something is required to be done. But you must be sure that you are writing a non-blocking event driven code. WebSocket was designed for Web Apps and it takes advantage of Node. A typical client connecting to a Node server and staying connected uses about 20kb of memory, and almost no CPU time.

4.    It is as good as it can be and it is just a new trend. Node will naturally find its rightful place. It is great for Sockets and is not mature enough. It is part of the MEAN stack, which is also a hopefully soon-to-die trend. Still it can be a valid choice for cross-platform desktop applications.
Node.js developers will prove that it can bring advantages that other solutions lack, for cross-platform desktop/ mobile applications, for sockets. But what Node.js is not, is a magical tool that should be used in every possible situation. It is not a fast language, and should be used accordingly.

Has Node.js declined already?

Node.Js Development

It is being considered by some of the developers that node.js is something that might be the best and unique solution that can solve almost everything. It may be that other technologies can be more mature or mature to work for any specific projects. The near future of node.js appears as more to be the start of the same competition as on the client-side, than the start of decline. It is somewhat painful at start, but the client side JavaScript / HTML 5 competition has been very productive in innovation & performances. Node.js developers are the expert who use to continuously work for projects and development, which indicates that the decline is too far.

The decline of Node.js

1. CommonJS work has stopped unfortunately, but there is availability of Node.js Foundation which is already on board representatives from: IBM, SAP, Joyent, Microsoft, PayPal, GoDaddy, Groupon, Intel, Digital Ocean and many more. As this has led to a foundation, in future Mozilla, Oracle, Chrome and Apple may ultimately join them.

2. Enterprise JS coalition is being supported by Adobe. The Node.js foundation has become a Linux Foundation Collaborative Project. The job trend is almost non-existent as compared to other one. In a more clear way, Node.js is fairly starting to rise up.

3.  Node.js may appear in the future with lots of changes, but they would also result in great enhancement for the whole community. So, it is growing maturely to higher level. There should not be any confusion between “declining” and “not growing too fast” observed from the condition of Node.js. it may be the fastest growing platform ever.

4.  Node.js has stood beyond expectations and most of the major technology companies have at least some amount of Node.js running in their stack. By all measures, Node.js has been a great success and has become a top language on job request. It is just quite popular but it is surely not declining. It is more promising and great for asynchronicity and not concurrency.

5.  This platform is superb for single-user applications (such as web apps, games, command line tool) but not for bigger backends. There are both positives and negatives to Node.js but it doesn’t mean it is declining.

6.   As people try to use Node in real enterprise scenarios, there is now an element of attempting to “reinvent the wheel”, by adding package upon package to patch on functionality that already exists in Java, .Net, Ruby and PHP to some extent.

Node.Js is progressing slowly but it is surely not declining. It has a number of applications and language support, mostly for single user based. It is more promising and fairly rising with bigger steps on development. It is already been to a great success and so there may not arise any question regarding decline.

Is node.js the future?

Node.Js Development

Definitely, Node.js has the future. V8 and JavaScript at the core give it some interesting features, event- driven nature gives it out-of-the-box scalability for most regular projects. It gives a rapid development cycle is of foremost importance in today’s condition. Node.js developers are always involved in development and update of apps which marks the future of Node.js.

The future with Node.js

1.    ES Next and ES6 is developing the language further, making it both easier to reason to beginners by adding syntactic sugar and tools like promises, for easier reasoning about async, and other similar features. All this eases getting into the JavaScript / Node.js ecosystem which also brings advanced features, such as generators, possibly strict typing and similar features important for the enterprise sector, which means bigger projects, more support and stability.

2.    It may be slow to introduce it and it may be bleeding edge and good for companies, in the future it may have a much bigger impact and usage. Even if another programming language such as Go or Elixir sometime is more popular than Node.js, so still Node.js has the advantage that one can use the same programming language as in the web browser, and therefore always certain fields of use.

3.    It is certainly on the track to be a significant part of future. It is already getting pretty popular being that it allows for client and server side development in one language. It will be specially a great thing for freelance full-stack developer. It is already the present. Just look the JavaScript projects in GitHub, the majority is related to Node. The question therefore arises, whether another tool will replace Node the future.

4.    It has replaced Java at Paypal and is extremely concurrent. It will be most probably as popular as Python but the problem is, not many people like JavaScript, especially in the scope of Node.js Development. Being JS driven, Node is uniquely congruent with the application ecosystem available in browsers, so as long as web exists, Node will power it to a massive degree.

5.    The ability to do non-blocking IO programming with ease in Node.js development is also a clear advantage. Node.js will continue to evolve, when big companies like Microsoft and Google are all supporting it.

It has a number of projects in the present generation and it would continue the same with the future. It may not be the fastest but it is work oriented and plays a significant role for the future. It is replacing other languages and framework and is expected to improve a lot in the near future.

Is Node.js Scalable?

Node.js Development - Laitkor

Yes, it is scalable in the sense that “it can be scaled to indefinite size,” but not as other way you are thinking to suggest. Scaling doesn’t generally involve just getting a more powerful machine, although that can make you a way. Node.js developers are the responsible members who care for Node.js development and security.

Scalability of Node.js

1.     It has limits and to call it scalable sometimes, it should have those limits. It is vertical scalability and you need horizontal scalability. You can run a cluster on a single machine to use all the CPU cores to do that. And you can also run multiple machines to spread it out further to spread the load by using a load balancer.

2.     You can sometime run Facebook scale on Node, and it would probably be cheaper than what they have done with PHP, but it won’t happen by default.

3.    If you want a site that has moderate traffic, uses a CDN for static assets, and uses a database that is itself scalable, you could probably do ok with a single-threaded instance of node.js doing nothing special. Depending on how you designed things, this could be a major engineering effort, or a relative straightforward one.

4.   Scalability is always more about implementation and hardware than the choice of server platform. Facebook even found a way to scale PHP.

5.    Node.js is not scalable by default. If you run clusters, use a load balancer, cache as much as possible in memory, write efficient database queries, serve static content from a separate machine (or S3) with a CDN in front of it, and fine-tune your client side with caching and reduce the number of redundant requests. Then you are relatively scalable infrastructure.

6.   Node.js usually scales better than most other typical platforms because of its event-based model. You can understand this as, Say you have a service with intermediate amount of work to be done- some database work, some data conversions, auth and the regular stuff.

7.     Node.js needs something like 80-100 MB of RAM at the start, and waits for request. For each request to a db, Node will fire that request, and then- go back to sleep- while it waits for results. So in typical use case, an average developer will make more scalable server with Node.js development, simply because Node.js doesn’t do anything at all 95% of the time.

Node.js by default runs on a single thread that can be solved by clustering. It can be scaled using the factors mentioned but then again so could most apps in most language. There are ways in Node.js to scale other than using a high spec machine. Scalable applications are not just dependent on systems but rather the application architecture used. Node.js can be a great asset in any scalable network if used properly.

What are the best practices for Node.js?

Node.js Developers

The cluster module for Node does not support v0.6x. Node v0.7 will have native cluster support but there is currently a gap in this area. It should be cared that as soon as you find a part of your app that could be broken into generalized things, break it out into an npm module. Node.js developers are one of the best developers into practice and development.

The best practices for Node.js developers

1.    The developers practice test driven development. This is always important to combine few of the best practices for asset-packing, authentication, error handling etc.

2.    Consider some of these generic suggestions for your work development:

•    Use something RPC-based like NowJS, dnode, etc. for real time webapps.
•    To restart your server when you make any changes to a file, you can use nodemon.
•    To log exceptions and get detailed instant notifications, you can use Airbrake.
•    To combine server logs from multiple machines, use Loggly.
•    You can separate your configuration setting into a config file and use different settings for Production & Development environments.
•    Append a GET parameter hash of the contents when serving static files.
•    You can avoid static file service from node and use a CDN for bigger projects.
•    Version your static files so that the file path is automatically updated when the file is updated, which will prevent polluted cache in browsers and proxies.
•    You can use PaaS provider such as Nodejitsu, Modulus, etc- unless you really love being a system admin.

3.    CoffeeScript: Once you start to dive into it, you’ll come to realize just how powerful it is in terms of loops, splats, etc. it may be not the best practice, but definitely a must-have for sometimes.

4.    Forever: you can use it for long running processes like servers and workers, especially to handle auto-restarting processes running in production.

5.    Underscore: it is great client-side library, and equally amazing server side library for various helper methods.

6.    Some of the startup practices for Node.js developers are:

•    You can start your project with npminit.
•    You must always specify start and test command.
•    You must save developer dependence in your package file.
•    Divide codes in modules and use module.exports instead of exports.
•    You must write codes by following any design pattern (Observer, Singleton, Factory etc.).
•    To specify development stage, you must use Node.js process environment variable.
•    When you make changes, use nodeman to restart your server.
•    Follow standard coding guidelines such as casing, variable declaration.

Best practices for Node.js in production environments are not much different from best practices while using node in general. The main start of your project should be with npminit and use nodemon if you restart your server by changing files. Similarly, there are many other practices that are most important to be considered by a Node.js developer’s right time.

What is the impact of meteor.com framework on the Node.js ecosystem?

Node.js Developers

For any front-end developer who never looked into how database and security works, when you see this, it might blow your mind and make you think you can really be productive now.

After getting into it, you will see that a lot of stuff isn’t figured out yet. It takes many years for Mongrel to be made for Ruby but still speed is still an issue today. The node.js ecosystem has handful of Node.js developers to manage the platform, but sometimes it may get an impact of other sources as well.

Impact on Node.js ecosystem by meteor.com framework

1.   Meteor has a different set of problems, which are the kinds of problems that prevent users from starting. Every User needs a secure authentication that they can trust and exposing the data layer to the front-end only works for some things. It is cool to build games or other vital applications for fun but real business apps need a few more features before it could be thought of a real platform.

2.  Whenever you compare two things in open-source, you may observe that active projects can change quickly. So there is any kind of flaw today in one system, it can be corrected the next day and become an advantageous tomorrow. There are dependencies that could make one system more or less attractive than the other, which say more about the dependency than the system being evaluated.

3.    When a technology is used in a powerful way (here Meteor using Node) that actually validates the technology somewhat. Meteor should therefore help the Node community, with its ideas (shared via OS), and ambitions.

4.  However, it won’t have much impact. Node.js wasn’t built to be a generic web framework. Node.js will still do what it does well, event asynchronous IO. Meteor appears to be a sensible JS web framework but so have a whole bunch of competitors like Socket Stream and derby.

The app written on Meteor will usually feel faster than the app written directly on Node.js. And the meteor app will generally use less server resources, but might put more loads on the database. However, Node.js is more secure and can be trusted. Node.js won’t have much impact, since it wasn’t built to be a generic web framework.

Why to choose Node.js for web applications?

Node.js App Development - Laitkor

The non-blocking I/O operations are a very strong feature of Node.js if a “real time” experience is required since it allows it to handle a large number of long lived connections to the server. Certainly frameworks like Async.js and CoffeeScript can make your Node.js code much more concise if verbosity is a concern. You can find Node.js as a simpler framework to produce a web interface that can deliver an experience that is much more interactive with the user. Node.js developers are regular in web servers and app development which makes it more trusted to choose Node.js for web applications.

Choosing Node.js

1.    Node.js executes all I/O operations asynchronously. This means that it would not make your program wait for the completion of an I/O operation, like accessing a file, a database, a network connection etc.

2.   A single thread can manage the execution of multiple panel I/O task, thus making a more efficient use of a cPU and memory resources. This makes it ideal for handling the requests of many simultaneous users on a single machine.

3.    Here are the list of features which makes Node.js as goto technology:

•    It wins the speed
•    It has efficient tooling with NPM
•    It also wins the data streaming
•    Real time web applications area  walk in the park with Node.js

4.    It is also suitable to be a game server, it can provide data read and transfer with thousands of users simultaneously. But in enterprise application development, choosing Node.js is not a wise action because Java is more mature in this domain.

5.    Node.js is a platform built on Chrome’s JavaScript runtime for easily building fast, scalable network applications. It is perfect for data-intensive real time applications that run across distributed devices. It has the power of dynamic server compatibility, cross platform compatibility and has I/O data driven technology.

6.    If you ever want to have an application with real life experiences, it’s time to encourage yourself with that superb feeling because making use of Node.js you can actually transform your ideas into real-life experiences (means an application).

The Node.js single thread event-loop environment was not this only one of its kind but it made this paradigm accessible on the server to a huge community of developers with a very easy way to share contributions. Node handles I/O with an excellent manner and also it is suitable for applications that requires a lot of connections such as online games, chats etc.

Which companies employ Node.js in production?

There are many companies that employ the use of Node.js Application Development service in production. Today, Node.js is ready to be used in an enterprise environment. Many of the reputed companies are using Node.js in some or another way. Most of these implementations are not for their primary web server, but for services, tools, mobiles, etc.

Node.js Application Development - Laitkor

Most developers actually feel that Node.js is ready for production use for any size of the company.

NODE.JS IN PRODUCTION

1.  When you want to run Node.js in production, you need to maintain stability, performance, security and maintainability in mind. The load balancer is required for health check and balance traffic between the servers.

2.    Linkedin, CBS and Walmart use Node.js for mobile. LinkedIn is using Node.js to power the Mobile server, which powers the iPhone, Android and Mobile Web products. In a nutshell, Walmart is able to serve some of the very sophisticated features to mobile users on the client side using Node. It’s saving mobile shoppers a lot of time by adapting content centered on device type and browser.

3.    PayPal’s web applications are stirring away from Java and onto JavaScript and Node.js. Node.js help you resolve many problems by empowering both the browser and server applications to be written in JavaScript. It merges the engineering specialists into one group which may allow you to recognize and react to user’s needs at any level in the technology stack.

4.    Yahoo has free some things for node and cares cocktails- a Node.js platform. It also customs Node.js in the livestand infrastructure.

5.    Pinterest is one of the hottest new startups today that uses Node.js as a webserver in some instances.

6.   Mozilla has implemented Node.js Application Development to support browser APIs which has half a billion installs.

7.    Ebay hosts their HTTP API service with Node. HP use Node for their WebOS initiatives.

8.   There are obviously a lot more, but that list has the majority of the major biggest companies. Some companies are using them in very specific places, but you don’t re-write the Microsoft dot com website in a year.

9.   A lot of the presumed companies have their focal site, mobile sites, tablet site and iphone and ipad apps all run against a Node.js system. All the heavy lifting including e-commerce, social media, API, business logic, etc. can be done by Node.js Application Development.

10.    Trello is a great real time production building with CoffeeScript and Node.js. TransloadIt is a file upload processing service that is claimed to be the first commercial software / Infrastructure as a service product built on node.js.

11.    Yahoo has tested with Node.js Application Development in association with Yahoo Mail, but it has yet to be seen whether they will organize a new version of Yahoo Mail that uses NodeJS. If so, that would be a remarkable and a large production deployment. By the latest this year, Uber, Quizlet, Voxer and LinkedIn are the largest production websites powered by Node.js. Plurk used node.js in production, handling 100,000+ users connected at once.

The very first thing you will have to do on the server is to set it up to route node. A lot of company’s names that uses Node.js in production are referred above. Among them, Walmart, LinkedIn, PayTM, PayPal are some of the many large reputed organizations using Node.js.
