Node JS is the second most preferred and popular technology for web development. If you are wondering what practices you should follow to boost the performance of your Node.js app, then you have landed on the right page. This blog post contains all the top Node Js best practices that you should consider in 2022.
How you fix the issues that completely depends on the Node js best practices you follow. According to toW3Tech statistics, Node Js stands at the top compared to other popular web servers such as Apache, Nginx, Cloudflare, and more, based on its popularity and traffic.
As you have chosen this highly used, amazing wholesome library cum web-server Nodejs for your project development, follow these Node Js back-end best practices to attain the maximum benefits.
Stop writing bash scripts. NPM scripts make it a lot easier to organize code. NPM init command will create a support framework called package.json. We all are aware of NPM and its procedure of installing dependencies, but it’s more than that. Node Js package manager is a part of all the deployment systems for Node Js.
The package.json allows you to create a lot of metadata to make it easier for others working on the same project by offering them the same setup. This secure and reliable package management provides an opportunity for the Node ecosystem to grow exceptionally well.
If you are wondering how to be a productive developer? The answer is to use a style guide. Most of us invest our valuable time in reformatting the braces, changing the spaces to tabs, and trying to make sense of the code that we have never worked on earlier.
A style guide is an ideal way to follow to understand the blunder. When a code is written in a consistent style, it reduces the cognitive overhead of spaces and tabs.
We would like to advise you not to mess up your project with environment-specific configuration files. Instead, leverage the benefits of environment variables. Use environment variables from the very early stage of a project to ensure no outflow of sensitive information.
Use the Below commands to set default values via npmrc file:
The procedure advised in Node Js is to add the values from process.env in your code.
Fulfilling expectations is essential for any application, and the ideal way to deal with mistakes is to use asynchronous structures. For example, promises offer a .catch handler to treat all errors appropriately.
The nature and design of Node Js are single-thread, which means lots of synchronous can lock the application. Synchronous functions in a way that makes your application logic easy to understand. In comparison, asynchronous structures like promises keep your code free from blockages.
If you are avoiding the synchronous methods in your code, it is still possible to use it at a later stage with the help of an external library. The ideal way to use asynchronous is in critical performance sections.
You are following the best practices to deal with errors. However, suppose the errors are still bringing your application down. In that case, this is where it’s ideal to use process manager to ensure the application recovers elegantly from runtime errors and restart your application as soon as the server is live again.
It is advisable to load all your dependencies and organize them upfront. So from the very beginning, you can easily encounter if there is any problem, not after a day or two when your application has gone live in production.
Some questions are worth asking in the development stage to speed up things.
To enhance application performance by concatenating and minifying multiple JS files into one. If your application has 5 JS files, the browser will make five separate files to fetch them. Avoid the block and wait time.
Nowadays, most clients and servers support gzip. The server itself compresses the response time when a gzip compatible browser requests a resource is, reducing latency and time lag. Gzip can improve your application’s performance when you make requests to remote servers and respond to clients.
Every application is composed of generated files and essential files. It is advisable to avoid tracking anything formed using source code like Git, as it leads to excessive noise in your Git history when you track generated files.
Due to Model-View-Controller frameworks like AngularJS and BackboneJS, have become a lot easier to create dynamic page applications. Using client-side rendering in Node Js will radically save bandwidth and reduce latency.
How does it sound to get notified when something goes wrong with your application? You don’t want to get aware from social media feed or thousands of angry users that the application has not been correctly functioning for a few hours now. So occupying something to alert at the time of critical issues is essential.
The risk of database manipulation increases whenever JS strings are frequently used. Built-in parameters for queries given by object-relational mapping should be used to stop SQL injections.
Testing is an obvious point, and it will save you on many occasions. In-between the development, it happens when the first few production issues occur. You wish you could have done a few tests in the first place. So, start developing the habit of testing and experience a smooth and bug-free application performance.
Lately, big names like Twitter, Walmart, Uber, and more have used Node Js for better performance and results. If you wish to be on the top list of such mammoth businesses, hire NodeJs developer from us and play your last card as an entrepreneur. Success is sure to come your way.
Always prefer to use a package.json to improve the performance of your Node JS application. Moreover, go Asynchronous and try to use lightweight code for optimal performance.
NodeJs is mainly used for traditional web applications, real-time applications, network applications, and back-end API because of its single-threaded behavior.
To keep your web application safe and secure from any attacks, you should always follow all the open web security project practices ( usage of Lint plugin, stop SQL injections )to avoid any NodeJS application vulnerabilities.
Promise is mainly used in Nodejs as a value placeholder that can be used in the future whenever an error occurs, or any asynchronous task is completed.
