Node.js’ magical tips and tricks every developer should remember

The world of software application is no doubt continuously evolving, keeping Node.js developers as the vital source. Node.js is one of the best versatile software that has allowed developers to create reliable, fast, and not the least scalable web applications with few code lines. Overall, you can say the invention of Node.js has offered much relief to the developers.

So, if you are a web developer or view it now for hire full stack node js developer and looking forward to some cool tips and tricks, then without any delay, let’s get started: –

  1. Always use built-in Debugger- Node Debug.

If you have a language with heavy IDE integration, for example, Java or C#, this app called Node.js will become complex. In this case, many of the web developers look to use the flow debugging pattern so that they can use console.log. 

But, for your information, I can tell you Node.js comes with a packed built-in debugger which you can run by a node to debug. 

  1. Use nodemon for development.

When most web developers start using this app, the most irritating thing they come across is using Control+C for running various things and again getting back using node for small changes. 

So, if you are frustrated with this, you can use one excellent package called nodemon. 

It monitors every change precisely but automatically restarts the server.

  1. Shortening an Array in a straightforward way

This is another awesome tip, or you can trick web developers by which they can shorten an array very easily. That means they can use the length method in which they have to pass a number that shows the new size of the array. 

let array = [“A”, “B”, “C”, “D”, “E”, “F”]array.length=2

console.log(array) // [“A”, “B”]

  1. Notify to Gauge the overall performance

Once you have developed the node.js app and after it runs, every web developer wants to check the app’s performance, whether it is running at the optimum speed or not. Well, this step is quite logical; every developer does on the node.js app. So, if you want something easy, then you take the help of the service called Nodefly. 

However, from just a few lines of code, this service starts monitoring the  node.js app for various issues like a memory leak, etc.

  1. Use isString

This useful tip will help the web developers or view it now for hire node.js developer to check whether any of the values or data are in the string format or not. However, isString is quite handy when you are requesting info right from the server and need to check the type of data.

const isString = value => typeof value === ‘string’;isString(‘JavaScript’); // true

isString(345); // false

isString(true); // false

  1. Make use of isNumber

isNumber is another helpful tip for the web developers to check a value or any of the variables while creating an app is holding a number in the form of float, integer, etc or not. 

function isNumber(n) { return !isNaN(parseFloat(n)) && isFinite(n); }console.log(isNumber(900))  // true

console.log(isNumber(23.98))  // true

console.log(isNumber(“JavaScript”)) // false

  1. Use Node Shell

If you want to test the node.js function to check how it works, then the node.js shell will work great on it. For this, you just have to run “node,” by which you will come to the node shell. After that, write code in a text editor. It will offer results. 

Moreover, if you are done with this, the node shell doesn’t offer an exit or quit option or any other command. To exit, you have to write a Node.js statement to exit the process. 

$process.exit(0)

  1. Try to shorten the log.

If you are tired of writing console.log every time, then this tip will be handy for you to shorten the console log while speeding up the coding.

var c = console.log.bind(document)

c(455)

c(“hello world”)

The bottom lines

This age is known as open-source, where you can learn many things from the trusted sites and apps in the public domain. That means the learning part never stops just because of past failures.

I hope this article has cleared all your confusion and frustrations regarding node.js. But you must say these tips are just the reflection of node.js by which you can do almost every work easily.
