How Will You Debug an Application in Node.Js
Being a Node.Js developer is considered as one of the trendiest profession. Node.Js developers are quite scarce in the computer science domain. Here in this article we will be sharing some useful tips which will explain as how will you debug an application in Node.Js?
Ways to Debug an Application in Node.Js:
Our team of experienced and diligent developers have eked out three ways so far, to debug an application in Node.Js. We will be sharing those ways right below.
1. The Built-In Debugger:
Mostly, if ever you have done even the simplest kind of Node.Js development, you are sure to have some knowledge about the built-in Node debugger. Its working mechanism is it basically supports the placement of debugger statement in the source code which is written by the coder or developer. The only condition your code is going to break is when you type the following line of code:
node debug [your app]
This command will act as the breaking condition and your code will stop working because only by doing this, your app will be running in the debugging mode. While debugging, you can inspect various elements of the app by opening the REPL just by typing “repl”. You can reassign the values of the variables as well.
2. Node Inspector:
If you are more of a technically advanced Node.Js developer, and you want to test your Node.Js application by using a pretty nice graphical user interface, Node Inspector is your debugger to opt. Mostly, it remains unknown to many developers because they seem to be OK with the built-in debugger. The Node Inspector works pretty well with Google Chrome and Opera. For other browsers like Mozilla and Edge, changes are underway so that GUI based debugging is taken to the next level. For the browser settings to conform with the debugging, you should get into the developer tools and then you can do the rest.
3. IDE Debuggers:
Another best and mostly used way to debug a Node.Js application is to use an integrated debugging environment. A best tool for this is Web Storm. The process is also pretty simple. First off, you need to set your project up in the Web Storm IDE. After you have accomplished the proper setting up of the project, just run the debugger like you do with any other IDE.
Above mentioned ways are the ones which are pretty simple and a developer can choose any of the mentioned methods that serve the purpose of debugging an application in Node.Js.
