Best Node Js Practices for Building Node Js Applications in 2022

One of the most popular frameworks for web development is Node.js. It is utilized by a variety of businesses, ranging from tiny initiatives to huge solutions.

By creating JavaScript code for the browser, you can construct lightweight, scalable, quick, and resilient server-side web applications.

Today, we’ll go over some recommended practices for Node.js development that will help all kinds of developers create a more efficient and maintainable application.

Best Node Js Practices for Building Node Js Applications in 2022

Following these Node Js best practices will help you get the most advantages from this widely used, wonderful complete library cum web-server Nodejs.

Separate Your Solution Into Components

Maintaining a big code base with several dependencies is one of the most difficult tasks for larger apps. While adding new features, this slows down production and development. We should partition the whole software into smaller components, according to Node.js best practices, such that each module has its own folder, and that each module is kept basic and short.

Some proven and verified best practices for Node.js development services include the building of modular apps by splitting the whole software into modular components. We won’t have to share code with anybody else this way (e.g. APIs, services, data access, test cases, etc.) This simplifies the procedure. As a result, reasoning about it is pretty simple.

Formatting and Linting

Every developer should strive to enhance the quality and readability of their code. A code linter and formatter are always included in most code preparation operations. A linter alerts you to faulty code that is both syntactically and semantically wrong. A code formatter, on the other hand, styles the code in a more understandable manner by assuring and enforcing standard formatting and stylistic principles across the whole project. ESLint, JSLint, and JSHint are some of the most well-known JavaScript linters.

ESLint is the industry standard for detecting and correcting potential code mistakes and style problems. It can establish code styles automatically, although other tools, like as prettier and beautify, are more powerful in formatting code and operate in tandem with ESlint. Most IDEs/Code editors, such as Visual Studio Code (VS Code), Atom, and others, include plugins for these linters and formatters.

Make Use of Environment Variables

We recommend that you avoid using environment-specific configuration files in your project. Instead, take use of the advantages of environmental factors. Use environment variables from the beginning of a project to guarantee that sensitive information does not leak.

Consider Going Asynchronous

Because Node Js is single-threaded by nature and design, a large number of synchronous operations might lock the application. Synchronous functions in such a manner that your application logic is simple to grasp. Asynchronous structures, such as promises, on the other hand, keep your code free of bottlenecks.

If you avoid using synchronous methods in your code, you may still utilize them afterwards with the aid of an external library. Asynchronous is best used in crucial performance parts.

After Each Change, Restart the App

During development, the program pauses and restarts with each change to the code, which may be inconvenient and cause loss of concentration and productivity. To address this, tools that prevent restarting the program periodically to reflect changes might be used.

The following are some of the most popular Node.js code monitoring packages:

  • Nodemon: It has an auto-restart feature that kicks in anytime new code changes are made. Simply substitute node with Nodemon to utilize it.
  • Forever: It also has an auto-start function, as well as extra configuration options like as logging logs and changing the working directory to a specified file.
  • PM2: A process management tool with superior control and functionality than the prior two.

In the production environment, both Forever and PM2 may be employed. It is possible to ensure that the code is restored after a runtime error, as well as a quick restart if the server fails.


So, these are the NodeJS techniques that you may find useful while creating applications. We guarantee that if these best practices are followed, your software will be easily maintained, scalable, and error-resistant.

Even experienced developers may embrace best practices and improve their programming abilities.
