Node.js is a web app Development framework that is specifically built on Chrome V8 engine and works as a JS runtime environment that helps in developing scalable apps easily.

Many times, it happens that this cross-platform and open-source technology might create complex errors, if you’re not strictly following Node.js best practices.

Let’s explore Node.js best practices in 2023 that help you design and build robust web Application for your business needs.

Node.js Best Practices in 2023 To Follow

It’s time to explore Node.js best practices that you must implement in developing robust web application for your business needs.

1. Initiate Your Node.js Development using npm init

   One of the standard and best practices of Node.js that you need to follow is to start your Node.js development using npm (Node Package Manager). The excellent part of npm is that you can efficiently add couplings and dependencies in your web application development.

   Moreover, npm plays an essential role in browsing all of the Node.js packages required for your business.

   It will be helpful to you, as it provides you with a new bundle for every project you create. In addition, with JSON, you may include a ton of metadata that will be useful to other Node.js developers working on the same project.

   With the help of Node.js, it becomes easy to add versioning-compliant updates of Node.js within the same package. This is among the most critical Nodejs best practices.

2. Setup .npmrc For Your Node.js Development

   The .npmrc file is the essential file, especially for Node.js developers. Do you know why?

   It is the sole responsibility of the .npmrc file to ensure that the npm install always updates the package.json and requires an exact match for the installed dependency’s version.

   So, just mention your script object and property in your node.js project’s package and a start key in the JSON file.

   Copy

   
   {
     "name": "albiorixtech",
     "version": "1.0.0",
     "description": "Project description",
     "main": "main.js",
     "scripts": {
       "test": "node main.js"
     },
     "author": "albiorix",
     "license": "ISC"
   }
   
   

   Now, everything is ready, and you need to push the command “npm start”. All the dependencies from node modules/.bin will be redirected to the $PATH, and you won’t need to install NPM globally.

3. Use Environment Variables

   Node.js is a programming language that requires robust configuration management. It includes the process of decoupling code, services, database configurations, and many more, especially during development, production, or quality analysis.

   The primary role of using the environment variables is to find the values from process.env in your code. For example, you can efficiently examine the NODE ENV environment variables.

   So, the biggest and most important Node.js best practice you must follow is appropriately using the environment variable in your program. In addition, you would use it to discover values during the web development process.

   With the help of the command nvm, you can quickly deal with the process of adding additional consequent plans, regular expressions, and setups. Also, it is one of the biggest advantages for many cloud-hosting providers.

   Copy

   //main.js
   console.log("Server is Running at "  + process.env.NODE_ENV);
   

4. Use Components For Better Application Structure

   One of the most challenging part for large applications is to prepare and maintain a huge coding structure with multiple dependencies.

   Such complex activities results in slowing down the developer’s skills and they cannot include new features in the existing Node.js applications.

   To overcome such situation, the best option is to perform the code partitions into components. In simple words, we can say that every components will have its own dedicated folders/codebase, resulting in keeping every unit small and simple.

   Let’s explore an example of correct Node.Js project structure.

5. Making Appropriate Usage of Style Guide

   The next in our list of best Node.js practices that you must follow is selecting an existing Node.js coding rule and ensuring code readability throughout the entire project chain.

   Let’s say your defined style differs from the developers who have previously worked on the project; what would you do?

   No worries at all!!! You need to replace the spaces with tabs or adjust the position of the braces, and you’re good to go. Yeah, it’s a time-consuming activity and is actively responsible for making your task tedious.

   I would like to personally highlight some of the core style guides that are specifically adopted by global tech behemoths:

   • Airbnb – https://github.com/airbnb/javascript
   • Google – https://google.github.io/styleguide/javascriptguide.xml
   • jQuery – https://contribute.jquery.org/style-guide/js/

   Trust me; it’s among the innovative and most preferred node.js development best practices.

6. Avoid synchronous functions

   If you’re using Synchronous functions in the Nodejs application, you can smoothly eliminate other coding functionality from running since it is completed.

   One of the best recommendations is that you turn on the -trace-sync-io flag, making it easy for you to ensure that no synchronous parts are now part of the code. Moreover, it displays a warning when an asynchronous API is encountered.

   The primary role of Asynchronous API is to prevent other code from running while it is in use. Furthermore, these functions are the most challenging factor for other programmers to understand an application’s logic flow.

   With the help of async functions, your coding throws an alert directly to your node.js app’s asynchronous API. However, it automatically outputs warnings and stack traces during the testing phase.

7. Handle inaccuracies

   A minor inaccuracy is solely responsible for getting bad feedback for your entire Node.js development process. It will eventually throw multiple errors on your business application, and there are more chances of losing your app’s customer experience.

   An application relies heavily on accurate exception management. And the easiest way to cope with the many programming faults is to adopt the asynchronous code structures for your Node.js application.

   For example, promises provide you with a.catch() handler that will elegantly propagate all errors to be dealt with.

   Copy

   
   //main.js
   doSomething()
   .then(doNextStage)
   .then(recordTheWorkSoFar)
   .then(updateAnyInterestedParties)
   .then(tidyUp)
   .catch(errorHandler)
   
   

   So, even in the case of failure of the previous function, you’ll get the error Handler option that will prompt you with the results.

   And yes, it’s one of the NodeJS best practices that every Node.js developer or business owner should adopt. Therefore, you must be following these NodeJS best practices for product development.

8. Confirm that your app restarts automatically

   Your web application can be efficiently affected by the slight mistake of dependency, even if you’re dealing with the perfect error-handling standards.

   So I recommend you opt for the process manager to ensure that the app recovers successfully from a runtime fault or when the server fails.

   Apart from this, the best option is to restart your program if you feel that your entire service fails. Your program needs to continue as soon as possible for this particular case. PM2 KKeymetrics is the perfect option for process management.
