Best Practices of Node.js Development
Node.js, a platform which is built on Chrome’s JavaScript engine aids to develop quip, scalable network application. It utilizes event-impelled, non-blocking Input/Output model which makes node.js compact and efficient. Over the past few decades, Node.js has become one of the rifest JavaScript execution. It is very easy to get started on the Node.js projects. But, once you get to transcend the basic “Hello World” app, knowing how to cope with errors and managing the exact structure of your code feels like a nightmare. Hence, we have some of the best Node.js practices which can safeguard you from the familiar Node.js traps. Let’s take a deep look over them.
- Utilize Functional Inheritance
JavaScript support prototypical bequest is when objects bequeath from other objects. The Class operator was also included in the language with ES6. However, it is convoluted when compared to functional inheritance. Avoid debugging and emphasizing prototypical inheritance or classes and utilize the functional inheritance like the other Node sponsors. However, with the implementation of simple function factory pattern and utilization of prototype “ new or this”, one can be able to simply implement the functional inheritance.
- Utilize npm scripts
Npm is a benediction to the node.js developers. Hence, begin your projects with the npm init. The node package manager is the origin of almost all the implementation systems for the node.js. The simple reliable deal management has permitted node environment to develop exceedingly well. The npm scripts will aid you in doing some fascinating hooey and maintain your code simple. Furthermore, most people are just conversant with npm as a way to install entities. However, it is not only limited to this, but it is more than this.
- Utilize Util and Configuration File independently
Always make an obsession with using the util.js file. The functions which are to be utilized regularly must be written in the util.js file. Manipulate this file as a variable in the module. Doing this will shrink the number of global variables and code length. And, make sure that you make a config folder that outlets your constant parameters.
- Utilize Granular modules as much as you can
When you start your project, always try to break your code. Node.js permits you to work with numerous tables. Thus, it is recommended to make divergent modules for various tables. As well, make another parent module for engaging within the child modules.
- Utilize environment variables
Configuration management has usually been an essential worry whenever we speak about any language. Ideally, detaching code from database and services that it has to utilize during development, production need and much more. It is recommended to utilize the environment variables in node.js. Look up the appraise from process.env in your code. Further, figure out which environment you are running on and check the Node_Env – the environment variables.
- Callbacks
Callbacks are the boss in node.js which specifically asks a worker to do a task and once the task is completed the boss will notify it. Callbacks are used whenever a developer has an asynchronous operation which required caller for the notification about the completion of the task. However, the notification will be sent only when the task is done.
- Event handler
An event handler is one type of callback which is called whenever an event takes place. Such phrase of the event handler is generally utilized in terms of User interfaces where the events like clicking on something, moving the mouse and much more. A callback is a procedure that passes an argument to another procedure. Whereas, the event handler is a procedure which is called whenever an event occurs.
- Handling errors
Always make sure that your node.js app is error free because errors will bring down your whole app. Good exception management is very essential for any app and the best way to handle the error is to utilize the asynchronous structures. However, we can emphasize it in a better way with the catch() handlers.
- Automatic Restart of node.js app
After following all the best practices of error handling there could be a chance of error which may bring your app down. Hence, it is essential to make sure that you utilize a process manager to ensure the app recovers seamlessly from the runtime error. Further, when you restart it, the entire server you are running on will go down. In such a situation, you need to minimize downtime.
- Testing is essential
On producing an app, it is crucial to get notified if something goes wrong. It could occur that you do not require to check your feeds and many users may tell you that the server is down and your app is broken since the past few hours. Thus, it is exigent to tool for alerting you for your crucial behavior. Some of the best execution tracking tools for node.js are NewRelic, Loggly and much more.
What is the difference between Node.js and Php?

Though both PHP and Node.js are both server-side scripting languages, they are shackled to have various resemblances but there exists various differences as well between the two scripting languages like:
- Runtime environment
- Complexity of use
- JSON
- Concurrency
- Execution speed
- Web server
- Package manager
