Know About Node.js Development – Tips and Best Practices

Node JS

Node.js plays a significant role in making JavaScript popular among the developers. The popularity of Node js development based on JavaScript engine can be credited to the efficiency and speed it provides to the development environment. The platform is easy to start, but as you move ahead the core functionalities of the app can become difficult. But with best practices and tips, you can make a huge difference between a launch disaster and a rock solid production app.

So, let’s have a look at some of the Node js Development Company for best practices!

1. Start Projects with NPM Init

Avoid writing bash scripts and organize your project with NPM scripts. Most developers consider NPM as a method of installing dependencies, but it is quite more than this. Node Package Manager is at the core of almost all the deployment systems for Node.js.

It creates the new package.json for you that allows you to add a lot of metadata to support others working on the project by allowing them to have the similar setup as you. This reliable, simple package management has enabled the Node ecosystem to grow well.

2. Make Use of Environment Variables

Avoid cluttering your project with environment-specific configuration files. Rather, you must take benefit of environment variables. You can use environment variables even for the early levels of a project to ensure there is no leakage of sensitive information and to develop the code properly from the very start.

The Node.js method advises to use environment variables and search for values from process.env in code.

3. Know about JavaScript Best Practices

It is a great idea to make sure you get familiarize with the best practices of JavaScript before developing the Node.js strategy. If you don’t have enough time for full immersion or you require a review of JavaScript, then important benchmarks you must learn are scope, asynchronous programming, function arguments, data types, objects & function in JavaScript, and more.

4. Using a Style Guide is Beneficial

Using a style guide can help you become a more productive developer as it reduces unessential choice. A common problem with the new project is that developers can provide a mixture of opinionated developers and no standard style guide. It is quite easier to understand code on a code base when formatted in a consistent style.

If style is dictated, the code base becomes a lot more manageable. It is always better to go for an existing set of guidelines and follow them. This way, you don’t have to pen down your own rules either.

5. Handle Errors Efficiently

It is important for any app to manage exceptions and the finest way to deal with the errors is to use asynchronous structures. For example, providing a .catch handle propagate all errors to be treated, cleanly.

6. Go Asynchronous

Node.js is designed single-threaded. This implies lots of synchronous components can lock up the application. Synchronous functions in JavaScript can block other code from running till they complete and they make the flow of your application logic convenient to understand.

Contrary, asynchronous functions like promises bring back a lot of reasoning and keep code free from blockages. It is possible to avoid synchronous methods in the code and to inadvertently use an external library that has a blocking call. All this can severely reduce the performance. The finest way to use asynchronous APIs in code, particularly in performance based sections.

7. Follow Automatically Restart of the App

Possibly, an error from dependency can bring your app down. It is when the use of process manager is necessary to ensure that the app recovers gracefully from a runtime error.

If your server running on goes down, you again have to restart it. Here, you would want minimal downtime and the application to restart as soon as the server is live again.

8. Improve performance and Reliability with App Cluster

Node.js runs in a single process, by default. Usually, you would want a single process for each CPU core so you can distribute the workload across all the platforms. In addition to this, if a worker crashes the others are also available to handle requests.

An important thing to consider is that each process is standalone. They don’t share memory or resources. The app cluster will provide you with easy flexibility for the future, even if you are running a single process on the small hardware today. You can begin with the reasonable defaults offered by the platform with a simple fallback.

9. Load Your Dependencies Upfront

Always try to load your dependencies and configure them upfront. This way, you will be able to know from the beginning if there is any issue, not five or four hours after the application is live in production.

10. Application Monitoring

It is vital to get informed when something goes wrong with the application and employing monitoring alerts to critical issues can help in that.

To Sum Up

We hope these tips and best practices for Node js development are useful while you are developing new projects. AIS Technolabs being a leading Node JS development company offers an extensive assortment of application development services.
