Node.js versus Python, Development Benefits

Node.js Development Services

According to consideration with regard to the possibilities, it could be said that there are versatile reasons due to which development in Node.js differ from that of Python Development. Though it is similar to developing in other languages, a lot can be made of Node’s asynchronous nature and at the same time you can perform event-driven apps in Python.

It is not so difficult to deal with, rather simpler to undertake. If you are a great developer and you love JavaScript programming, then no doubt you could easily trace the benefits of Node that it’s purely subjective.

Yet most of the programmers are expertise at using different programming languages for different tasks. On the other hand if we consider it programmatically, it is also followed by some disadvantages as well. Being a newer language and less specialized, more bugs, less documentation, and missing pieces, can be expected here. No doubt all these things are being improved with the passage of time to the modern and technological innovative era and there is an active community around Node. At the same time you can also find many active community around Python, Django, Twisted, etc. as well.

You could be able to use a technology that is considered very hip now-a-days by exchanging those bugs and can get credibility with various kinds of people. It is just similar to Rails circa 2006-2007.

Keeping in mind, the relevance of such kind of stuffs could promote you to a broader advantages. You can also opt for Python (Tornado) as you would be able to start and operate it easily, having a good support.

Node.js is more beneficiary other than different development environment, including Python. Here Node is found more important. Let us relate this comparison between development in Node.js and python as question of fact in points:

1.    Node.js is constructed to handle asynchronous I/O from the very ground up, where as other developing environments are followed by a weakness to have async. Node is the very first opportunity where it is really all pervading. In all other environment you would find only limited pieces available in async. Thus, it became hard to write non-async code in Node. It’s really a good combination to a lot of common web and network development problems.

2.    Another point to be kept in view is that it’s just a JavaScript. Most of the time confusion is aroused for switches between Python on the backend and JavaScript on the front-end. You may be wasting your most of the time in making syntax errors- semicolons in Python, missing braces in JavaScript, etc. Thus switching couldn’t be a relevant solution rather you are wasting brain cycles swapping in and out your language knowledge. Staying in a single language gives you faster and better performance.

3.    Though it’s new, it has the benefit of being able to learn from previous mistakes regarding languages and environments. Ultimately, Node can correct those mistakes without the backward-compatibility concerns. Finally to say, Node looked very polished and modern and along with that it didn’t have time to accumulate the cruft which is available in other languages and environments.

4.    You would take time to learn Node completely. It will surely make you a perfect and better developer, whatever you end up using. It’s a cool software and great tools which should be available in your toolbox.

To conclude, both the software developers are independent of each other. Like if you are already using Python for some part of your system, you don’t need to load your team with other languages. It re-doubles the maintenance job.

You can use both the languages for both clients and servers and Yes Laitkor team is always here.

Will ASP.Net MVC development model overtake ASP.net webforms development model?

asp.net Development

Newer development models overtaking the old traditional ones that haven’t been much appreciated due to lack of upgrades is not an alien concept in the programming world. Developers are often down to apprehensions on whether the programming language they are currently investing their efforts in to learn and utilize might one fine day die when a new one hits market. Asp.net Webforms was already under the threat of being ruled out when Microsoft decided to turn the ball back into its court by bringing in MVC and investing all its efforts in making it competent and efficient for developers. Some saw a new beginning for asp.net development when MVC proved its efficacy at being preferred by many. Now those that have been using Webforms are under pressure of their model becoming outdated.

Changes and that too advanced and better ones are always needed and that’s what MVC brought along. Clean mark-ups, better control, and easy hand written codes in place of server generated ones which do not well understand the needs of client side technologies are some of the advantages of MVC over Webforms. New age Java script frameworks is an added advantage of course. When one can avail better equipped packages that would be easier and more efficient for ones application, there is no genuine reason to prefer the older one with lacking features. This could be one reason of the many that contributes to the overtaking of the new model over the older one.

MVC offers higher testability and less obfuscation of inner working which is mostly preferred by engineers worldwide. As some fellow developers would agree that Webform is nothing but a hack design intended to lore WinForm developers to web. However, given that one could always flip and convert Webforms sites to use MVC framework hence utilizing its benefits along with keeping up the efforts of the traditional ones, it is more likely that Webforms will not be dead anytime sooner.

With MVC, developers and designers can always work together without messing into each other’s code. You get more options to work with raw HTML and the codes look cleaner compared to auto generated ones with Webforms. However, there are some still who prefer the work to be done quickly and with lesser efforts with automated codes. They would prefer Webform any day over MVC which requires good understanding of the concepts related into the procedures but they are easily done with examples and support whenever required.

Those preferring MVC can always use Webform controls by selecting ASPX engine on the same project. Webforms will continue being used and as MVC has always clarified from time to time, it is never intended to replace Webforms. Glancing at the larger picture of asp.net, we do know that each of the models have its own advantages which cannot be replaced or copied. Some are still and will continue to be scared of trying the new models and they will prefer Webforms as long as they are clear on their requisites being met.

What is better choice for a startup company, PHP or Python?

Web App Development

When it comes to the problem of trade-off for startup company between PHP or Python, Python is found faster to develop as it prevents you from making a series of errors. Both choices are completely reasonable for a web application of low to moderate complexity. Still the progress depends entirely on viewpoint of one’s capability levels of dealing with the works as the overall deal site is relatively easier either way.

According to possibility, use of API’s might tilt your decision depending on the provider tool-kit/code samples. You should not worry about scalability at this stage. If you had a million uniques, you can afford to substitute two or three servers. It really doesn’t take that much to scale to that levels these days.

Only thing you will have to look after is to think about Master-Slave databases, model segregation etc. while Django was made for taking care of these stuffs transparently. You don’t need to bother about GAE unless you also want to learn another data storage method on top of your language. You should be careful to deploy anything on GAE until you have profiled your application and will have a clear prescribed estimate on the hosting costs, ideally as a function of use.

Related to the element “hosting cost”, a cheap webhost for initial development is <10/mth. For the process of launching, upgrade to a simple 50-80/mth onwards. For a startup company, PHP is quite cheaper. All amounts are far less than the cost of your time to bother about the cost structures. But after a certain period you will find it get more expensive to host and to maintain PHP Applications Development Services because you need to maintain more CPU for the same system written in PHP than from one written in Python.

To conclude, PHP developers are cheaper and are easier to trace. With the procedure of coding from the scratch, there lies the higher chance of making hardly reversible mistakes and in the tenure of long run you will hire developers and sysadmins who are already familiar with different frameworks. Thus, to know a new code base would lead to much more time taking procedure.

Which language is better: Python or PHP?

Python Developers

With regard to better language between Python and PHP, Python is considered more easy and effective language. Generally the suitability depends on the nature and scale of assignments. Reading difficulty arises in case of large projects. Lots of more activities are going on with Python in the cloud. Google AppEngine would be more likely perfect example. When it comes to construct a scalable application platform, PHP is given less advantage as compared to Python. Yet it still takes over Python when it comes to database operations, IMHO.

There lies a number of distinction between the two language, but the most important part of discussion should be- which is more comfortable with the viewpoint of readability. Neither can be given less importance as you can also prefer PHP because it’s hard to find experienced Python developers. You can move along with any of the one according to your preference, knowing what people around you are of the view. If you are viewing it as a learning part, both the options are valid. But if you want to deal with it, you should go with the one which you find more reliable, whose performance is good and in which you are good at. You may get to know better difference after working on your preferred option. One thing that should be taken due care is that the one you opted should not create hindrance for you and ruin your everyday work.

Let’s make some comparisons between Python and PHP. Python could be considered a good option as it has a philosophy that helps to write better for understanding code. Though Python developers are not easily found, it has more compact and clean syntax that helps developers. Here you can do the same thing in the same way. What iterate things you are using among list, tuple, string or something else, is of no serious issue. You can always access by index, get a slice, iterate over it or can get the length in the same way.

Python is characterized with more extended and powerful standard library, much better than PHP. Most probably it coincide with exceptions with the object to improve working with exceptions in the future versions. It provides you with better namespaces and importing. All the things included in it are objects types, functions, objects, modules which can be introspected including ABC collections and other good batteries. Apart from these features, it also provides you with better support of functional programming style and also gives a better Unicode support (much better in Py3k). It is implemented with improved interactive interpreter mode. However, PHP is being subject to some negative feedback because the auto typing in PHP is broken which will cast the char ‘0’ into false. Casting of empty string into false might be useful, but not in the cases of zero digit strings. Thus it is bound by some of these limitations.

Neither of the languages are better than another, nor are they similar. Indeed PHP comes with some common demerits, but with its assistance you can accomplish anything you are reasoning to do with it, within the limits of normal web application. You can get served in various more ways than in PHP. On the other hand, for developing a web page, PHP seems to be more suitable. Not denying with the fact that most PHP codes out there is horrible, but at the same time it leads from the people writing it are untrained hobbyists. The only factor of differentiation here is the skill off the developer. Just because of inexperienced developers who have only passed through a couple of tutorials with limited assignments, this language is termed to be bad.

However, what ever language you are looking forward to get your web application developed, Laitkor development team is the right solution, may it be PHP application development or Python Application Development.

Best MVC framework for PHP

Web App Development

In general, it is not the easy task to recommend the best MVC framework for PHP. The selection criteria for the framework widely depends on the nature of projects, preference and personal skills of the developer that what exactly he would be trying to accomplish. The only thing stranger to the purpose could do is that he can only suggest you the possibility and effective work of the performance. All other influencing elements lies with the developer. As a prologue, Zend framework would be a good foundation for everything which could also be used as just a library of various functions. It is also the nearest, being a official PHP framework.

Thus, a lot of developers could be easily traced, who are having a good experience about its working process. Yet this framework is followed by a drawback that such frame work could not be helpful to prototype something very quickly. There also exist several frameworks that could be used as a quick Rapid Application Development (RAD) tools.

Another good example of PHP framework is CakePHP, which is very popular among the one. As it is easy to learn, it is most welcomed and accepted by the learners. It is characterized by number of good features including the presence of lot of sensible defaults and naming conventions that make your life much easier and comfortable, still you can override it. Though it is hard to believe about the viability of the CakePHP project since some of the core developers have left in 2009 to form the Lithium Framework. However with the release of CakePHP 2.0, it got a particular promotional boost, which would be going to address number of issues developer had with the original CakePHP. Altogether this framework should be concluded to be an interesting and overall good to watch.

The next best one in this category is CodeIgnitor and its another version is called Kohana, which was initially started as a codeIgnitor port to PHP 5 and significantly developed to transformed into Kohana. These are pretty solid frameworks which is more popular among others. Yet another good and most discussed framework is Yii framework. It is considered to be suitable for dynamic development, AJAX heavy applications. For more advanced professional offering a lot of functioning, the framework are designed in bigger scale but its learning curve is having a steeper slope.

The perfect example for the satisfaction of framework designed in bigger scale is Symfony. It is well build and developed which also perform some multi functional activities which are nearly to be re-launched as Symphony 2. It also promotes heavily the working of the Doctrine ORM for data access, alternately allowing you to use another ORM called Propel.

After the following, Lithium Framework is another emerging framework in this category, represented exclusively for PHP 5.3. This one is designed by the original developers of Cake PHP who decided to start the newer more advanced framework from scratch. It include the heavily uses of the new features in PHP 5.3, including namespaces, closures, and late static binding and its appearance seemed to be more interesting from the designs perspective. This framework is highly recommended to be dealt in with even for the learning matter or goods coding purpose. It is also having its own database abstraction layer similar to ActiveRecord.

These were some of the frameworks having MVC, templating and database abstraction layer, most among them are based on standard PHP Database Object (PDO) library that comes with PHP. Even if you do not use any of the frameworks, you can generally practice PDO for database access as it helps in improving the readability and portability of your code with fairly modest overhead.

We at Laitkor aim to help our clients in every possible way and in case you get stuck at choosing the right framework for you according to your project, our expert panel can always be there to help you out.

Some surprisingly most useful PHP functions must to be known

Web App Development

Talking about surprising and useful functions of PHP, there exist a number of technical functions apart from the basic ones which are usual and mostly known to all who claim to be knowing PHP in the most basic ways. These are the beneficiary that one can enjoy in PHP.

Like you could be liking implode() to join arrays together into a string. There are many more functions of such kinds that you can find more pleasant in PHP and which would be the part of further discussion.

Once you have found and used implode(), you may also love to know about explode() to do the exact opposite of your need. The two amazing functions alone are worth using in PHP Application, viz. date() and strtotime(). These can also be used in JavaScript-heavy apps (especially helpful in Node.JS)

Let’s consider some of the useful and various PHP functions:
fgetcsv() and fputcsv() – you can use this function constantly to get and put csv data in order.

glob() -“ it could be used for the return files that matches a pattern (e.g “/tmp/*.*”).

array_push(), array_pop(), array_shift(), array_unshift() – this function is usually used to add or remove elements from the either sides of an array.

array_reverse() – you can use this function for flipping the particular array around.

set_time_limit() – use of PHP via CLI all the time and updating the time limit(30) inside a loop assures that looping any amount of data could be done through manipulating.

spl_autoload_register() – it could prevent you from the nightmare of managing include() and require() statements, combining with PHP namespaces and some sort of code directory structure.

phpcredits() – used to print out credits.

mysql() – it is an undocumented mystery function, call it for yourself!
eval() – it’s a gateway to realms of wonder

These are some most required functions other than asort, ksort, arsort, print_r(), empty(), mail(), header(), etc. which are fairly helpful too. Most of the users are yet not aware about these amazing functions. Other than that,the magic methods _get and_set are incredibly useful.

The language in PHP comes with an integrated development server since PHP 5.4. Due to this competing innovation you don’t need to setup an Apache virtual host for developing your project, just enter into the folder in which your code is and type – php  -S localhost : 8080.

The two old PHP functions strspn and strcspn are least known to the people. Basically they provide you with the option to search for characters in a string that are present or not in the other string. It is significant for parsing text without leading to split your strings in smaller pieces nor using regular expressions, helping you to write faster PHP parser. It could also be used for building fast e-mail message parser, HTML parser and filter classes.

Array Access interface is another function which allows you to access class variables as an array, which could be henceforth used to construct smarter Hash objects with consistent functions instead of using the plethora of array_functions. It’s also useful to template in MVC systems where you simply use PHP as the templates as well. The use of Reflection in PHP will guide you in solving most of the problems. Here you can inspect your big applications easily and can find the particular class or function defined, number of arguments, namespaces and so on.

In case you find yourself stuck while making the best out of any of these functions, you can always count on the support team of Laitkor to come to your rescue.

Which is faster Meteor or Node.js?

Node.js Development

To know the degree of fastness among Meteor and Node.js it is little complex to give the view. Here the comparison becomes invalid as Meteor is based on Node.js.

Let’s consider the following behaviors of Meteor and Node.js to conclude the result from different point of views. According to end-user, for someone using an application, the app written in Meteor will relatively be seen faster than the app written directly on Node.js.

Along with this, the Meteor app will also consume less server resources, yet it might put more load on the database. Using Meteor app facilitates you client-side code as well as server-side code. You may operate the client-side code easily on your browser. It uses Node.js to run the server-side part of your application. From this point of view, how Meteor could become faster as the part of its performance is dependent on Node.js. Here the reasons to prove that Meteor is faster and use less resource, though its part performance is dependent on Node:

1.    Meteor seemed faster to users because of presence of latency compensation in it. It means, when you perform something, your screen is automatically updated as soon as it is processed, without delaying to wait for your changes to go all the way across the internet to the server and comes back. Thus, elimination of the round trip time could be the great achievement.

2.    Meteor helps to shift a lot of work from the server to the client. For traditional web applications, the responsibility for rendering the user interface lies with the server. Here all these works are performed by the clients. The server only manage to send the client an occasional piece of data when something from data is needed. As a result, the Node.js process is having least work to do and could run faster. Finally, the Meteor apps generally have some form of live updating data, more load is given towards the backend database server.

These are the ways due to which Meteor is considered faster. Yet all these could be performed without using Meteor. Hence, by hand coding. Directly on Node.js. It has been done by some active developers who had practiced it on few apps like Trello. But this will lead to increasing the length of the work as it could only be done by some experts in integrating a number of different technologies.

Meteor is one way to write Node.js applications that are seemed very fast while using and also uses less server resources. Still, technically it is not faster because using it, you can build a faster app but not client-side frameworks, or just a subset of frameworks and libraries which are used by Meteor.

Why to opt Node.js for your web applications?

Web App Development

There should be valid reason to be accepted which can easily persuade users or development teams to Node.js web application development. The very strong and effective features of Node.js is the non-blocking I/O operations, if conditional “real-time” experience is necessary.

As it facilitates the allowance to handle a large number of long lived connections to the servers. Certain frameworks like Async.js and coffee Script are available to make your N.doe.js code more precise and brief if it is concerned with too many words.

Still you should not under-value the ability to share JavaScript code between the client and server. It is found more helpful in real time savings when you are developing the web application development which could be able to build up a set of modules that can be easily applied on both. At the same time it could lead to much greater specialization user experiences because here there is no existence of cost of having to port functionally in order to achieve some desirable behavior.

The very basic element that needs to be known is that “what is his core functionally?” and then after knowing it, substitute it in a JavaScript module that can be used on the client and server. Node.js is preferable as it is simpler to produce a web interface that can deliver an experience that is much more interactive with the development teams.

2.    Another point to be given due care is its package manager- npm. It represent the standard way to share code with the community and to co-ordinate external dependencies. It is not too old as it’s launched since two years ago and the number of module present in it has almost overcome the number of module published on RoR gems.

Here are some of the points listed articulately which would help you to express the viewpoint more clearly:
1.    The very basic function of Node.js which seems it to be useful for web applications is that it is fast and easy to prototype with concern to any kind of web application in a short run, compared to others simultaneously. For example, consider the behavior of JAVA and LAMP. Node.js provides the web server module itself, in order to enable you utilizing your own wit about setting up Apache or NGINX unless you want to integrate in the existing platform.

3.    Next point to be considered is that there are number of Platform available as a service solution like joyent cloud, heroku, nodejitsu which justify Node.js as first class technology and enable it to deploy and scale of your application trivial.

4.    There are complementary technologies available in Node.js, which are mongoDB and Redis, and they are very well integrated with Node.js. Normally a project dealt in with Node.js comes hand in hand with a NoSQL solution. Node.js will be definitely a good option if you are doing a project without a relational database.

5.    Another advantage would be presence of JavaScript and Coffee Script in it. As it is widely accepted fact that JavaScript is the language of the browser which made necessary for all web developers to deal with it.

6.    It consists of well-built architecture which enables you to overcome its performance and scalability problems, which is due to its non-blocking interaction. Its architecture is similar to NGINX, which leverages directly the Operating System event’s system calls to open up the development of all those normal real-time application which couldn’t be developed easily using other languages.

7.    Here you can avoid extra costs due to its high performance. This could be the biggest advantage to consider Node.js suitable for web applications. Though there is no need to construct HTTP or TCP requests to another server side language, working with the complex architecture, you can also manage to save in system administration time. Thus, avoiding Apache or NGINX setup and maintenance costs.

To conclude Node.js is suitable for web application development and let Laitkor be your development partner and torch bearer

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.
