At the initial stage of creating your assignment, you should make sure that you hire experienced professionals who understand their tasks. Node.js is not a magic tool that will work to achieve your project goals. It’s a platform that can solve certain problems, and you ought to know for what tasks and when it will be a useful tool. If you haven’t taken the time to figure out if the tool is right for your tasks, you may just be wasting resources and not achieving the results you want. 

What Node can handle is developing quickly scalable network apps. This tool can take an enormous number of concurrent connections with increased bandwidth. It equates to high scalability, so it is a perfect option if you need to give an app such capability. 

To make it easier for you to work with this technology, we’ve prepared a guide with some useful tips from experienced creators. Take advantage of these practical tips to make your interaction with the technology more productive. Here we go with NodeJS best practices!

What is NodeJS? Usage of this technology

Node.js stands out among the other web apps of our time that use push technology with web sockets. Why is this such an advantage? 

Node.js lets you develop web applications with two-way, real-time connections. It means that both the client and the server can initiate a connection to communicate. That is very different from the usual strategy we’re used to on websites, where the client always initiates communication. Previously there were networks without state preservation, and they were based on request-response without state preservation. It’s also based on HTML, CSS, and JS and works using standard port 80.

The main purpose of Node.js: is to apply non-blocking, event-driven I/O. It is necessary to stay easy and efficient against different apps that are also information-intensive on distributed devices.

With all its benefits, this technology now recreates a key role in the toolkit of many popular product companies. Using this technology correctly will allow you to achieve your goals and take advantage of all the benefits.

Let’s consider a typical node js structure best practices to improve your interaction with the technology. You can use easy tips to make your Node.js app as effective as possible.

Folder structure

So, let’s move on to the first of node js production best practices that will help you focus on using the technology correctly. 

Build a logical structure for your project. A clear hierarchy is significant for this tool, as with other common technologies. Divide your project into several logical levels so that this architecture provides you with a convenient arrangement of all project elements. Arrange the different modules in additional folders so that you have access to the suitable parts and don’t confuse the structure of your app. 

Such a clear hierarchy will clarify functionality and organize classes and methods into specific folders. This way, you can manage the elements and modules of the application more efficiently. 

Handle errors

Even the smallest mistake in any project development process can negatively affect the other steps. Sometimes it can even lead to the project being stopped. That is why it is significant to be able to manage exceptions precisely.

The best way to eliminate an error is to avoid it. However, avoidance often fails for a variety of reasons. In this case, you should pay special attention to errors. Implement asynchronous code structures. 

Check the correctness of the execution at each stage of development. The sooner you identify and eliminate an error, the less likely the application will stop or not function according to the proper script, so note this node js backend best practices.

Embrace async

The key idea of async/awaits techniques and generators in ES2016 is to make your code asynchronous. You’ve probably heard about these techniques, so let’s go into more detail. 

The problem with synchronous functions in JavaScript is that they can block the execution of any external code until it finishes executing its script. And so, asynchronous hierarchy in practice holds code complimentary of external locks. Nevertheless, synchronous code can make the flow of your application’s logic easier to understand.

For starters, you should run your application script during development with the –trace-sync-io flag. One of these node js good practices will allow you to display a warning and a set trace every time your application uses the synchronous API.

Use environment variables

Proper management of your application’s configuration is essential for every programming language. It is essential for code decoupling, services and databases during development or quality analysis. So here are the next node js coding best practices.

We recommend using a variable environment in Node.js. It will help look for values from process.env in your code. You can check the NODE_ENV environment variables.

Thanks to node js best practices for production from other developers, you can use an environment variable as part of your code at this point in the development process. 

Most cloud server vendors use the nvm command to avoid confusion and maintain a strict hierarchy. You can also use other sequential plans, regular expressions, and configurations.

Examine for Vulnerable Dependencies

You can use any open-source package during any Node. js-based web application development cycle. That is available in various development process management tools. You need to be sure about what features the package has and what edits will occasionally be made to it to leave the application completely secure.

In this practice, we execute functionality thanks to nsp or snyk, npm audit to monitor and fix possible vulnerabilities.

Employ client-side rendering

Using client-side rendering in your Node.js application can reduce latency and save bandwidth. Client-side rendering will enable developers to make their web projects completely renderable in the browser using JavaScript. A website with client-side rendering creates each route dynamically directly in the browser.

Client-side JavaScript frameworks provide an API and ship JSON answers to the client. It doesn’t happen as usual through a server, where each request returns an HTML page.

Entail all your dependencies upfront

Another of the node js deployment best practices is to do all the dependences of the assignment. We recommend that you identify and manage them in advance. By accomplishing so, you get potential issues before the client knows about them. It will help you learn about their causes and the problems they can lead to later. 

It is the reason why you should monitor and set up dependencies in the proper way. By doing so, you will know if there are real issues on the side of your application. Otherwise, it will only take some time before your task is up and running.

Say no to synchronous functions

Synchronous functions can greatly stop the performance of the rest of the code scenario until it completes execution. You should make sure that there are no synchronous functions in your code. To do this, turn on the -trace-sync-io flag, and you will get a warning when you encounter an asynchronous API.

The asynchronous API suspends the implementation of other processes while it is running. Besides, these features are still very important to simplify the flow of the application for other developers.

Also, consider that using asynchronous functions in development will, among other things, notify you of your project’s asynchronous API. You will get an automatic warning and stack trace during testing.

When choosing a development team, you need to pay attention to many parameters. It may be the reputation of the company, as well as the experience of working on the development of specific applications. Here the best advice is to look for developers by the recommendations of acquaintances or by the ratings published on the web. It is the choice of the development team that will determine the success of your future application. So make the choice as seriously and responsibly as possible.

If you want to develop a productive web app based on Node.js and are looking for a development team, then you’ve come to the right page. Our experts from Fireart Studio will help you create a project to achieve your goals.

What does taking advantage of the widespread Node.js technology give you? Assuming that your application does not contain memory-intensive scripts or access to blocking resources, then you can take advantage of Node.js in practice. In this case, you can get a chance to create scalable networked apps.

We discussed best practices for node js. When people encounter problems with Node, it almost always comes down to the fact that blocking processes are the root of all problems.

It’s worth keeping in mind that Node.js technology was never created to implement scalable computing. It was created to solve the problem of scaling I/O, which the technology copes with technique.

Hang the advantages of technology into the advantages of your app to achieve maximum results!
