Avoid These 5 Mistakes to Never Go Wrong With Node.Js Development

Simpalm is a popular app development in Washington DC and Chicago. The company has been successful in developing quite a number of web applications as well as mobile applications by using AngularJS. AngularJS is an open source and carries quite a powerful JavaScript framework. The company has quite a dedicated team of developers for AngularJS for building up the whole website in JavaScript stack like Ember, Node.Js, Backbone and Twitter Bootstrap.

Now, before we look into the 5 mistakes, which should be avoided so that a developer like Simpalm never goes wrong with Node.Js development, let us first look into what Node.Js is all about.

Node.Js

Node.Js is a software developer, which has an open-source, cross-platform JavaScript run-time environment that assists in executing JavaScript code outside a browser. It has a big package ecosystem known as npm. NPM provides a developer with access to a whole list of tools and this allows Simpalm to develop the high-quality enterprise apps easily by incurring minimum app development cost.

Let us take a look at the 5 mistakes, which a developer like Simpalm must avoid to ensure that they never go wrong with the development of Node.Js

  • Looking To Execute More Than One Callback:

For each and every JavaScript developer, callbacks happen to be quite a big thing. They basically allow asynchronous elements to communicate with one another. Still, at times, quite often it happens that developers constantly press for callbacks more than one time. Accidentally, callbacks are called twice. This is where, as a developer of Node.Js, like Simpalm, you invite trouble. The interface tends to freeze during the time when file loads.

So, for an app development agency like Simpalm, it would be appropriate to wrap up the callback, so that they can notice an error at any moment it is called two times.

  • Callback Hell:

Callback Hell is something that happens when more than one asynchronous operations pile up one after the other. If a developer like Simpalm can avoid functions from getting overloaded, then they can prevent callback hell from occurring.

  • The Event Loop Getting Blocked:

It is important for developers like Simpalm to realize that Node.Js carries a single thread. So, blocking an event loop will block all other things up. So, for an app development company in Chicago like Simpalm, it is imperative that they must look to address every case on an individual basis.

  • Using Up Console.log For Debugging Purpose:

A developer like Simpalm should never use console.log in order to debug. In Node.Js, the console.log will manage to print just about anything. The problem is that every time a developer inserts the console.log, they would need to restart the server and this would, in turn, slow the application down. One can avoid all these just by using the Debug module.

  • Take Up Numbers For Data Types Like Integer:

This is another mistake, commonly committed by developers. Any developer like must understand that in JavaScript, the numbers over there are not integer data but floating point data. In case the numbers manage to go beyond the limit of floating point, all the calculation will go haywire.

So, if the floating limits are well maintained, then there should be no problem.
