What are the best Node.js practices to create stellar apps?

Node.js is an open-source cross-platform JavaScript runtime environment. If you are building a product with Node.js, you can have a clear mindset that it would involve a dynamic approach. We can develop a number of tools and server applications using it. The event-driven architecture was introduced first in 2009. They make use of basic modules that are coded in JavaScript even though it does not belong to the JavaScript framework.

The popularity of Node.js is due to the efficiency it produces. The execution speed is another factor that attributes to the development environment. Nowadays, the internet is solely dependent on User Interfaces (UI). The JavaScript, platform of services and Node.js are ahead of combining all the services.

Ryan Dahl designed Node.js to integrate a large number of services with other applications in the equivalent UI.

The solution is also extremely cost-friendly when you integrate it with different legacy systems. There would not be any requirement to develop a number of platforms. Products can reach the marketplace in a faster manner with Node.js.

Node.js has been in-and-around the market for a long time. In the upcoming years, you will see a lot of changes in Node.js.

Let’s take a look at the best practices in Node.js:

Organize the code sturdily

Ensure that you organize the code into smaller bits. Try to make them smaller. This approach is to avoid more complexities. This would help you and your developers to understand the coding techniques involved and reason with it.

How would your colleague understand your coding if you yourself don’t? The code has to be simple and in addition, it has to sync up with the asynchronous philosophy of the Node. If you work on a different project, you should make sure to follow private registry or a cache strategy to deal with temporary solutions.

Don’t think twice to use Promises

Promises might be concurrency primitive. They are now a vital component in every recent programming languages. fs API does not contain readFileAsync to return a Promise. Hence a module similar to promise yall is required.

Don’t entertain Blocking Require

Place your every requires a statement at the file top. Owing to its synchronous nature, the execution will get blocked. Node consists of a simple module loading system. It makes use of CommonJS module format. You can include the modules existing in separate files by using the built-in require function.

With Require, you can import a file or module you exported. Here the require is cached. The resolved filename would not contain any changes. The code from the module would get executed. That would then get loaded for the single process to the variable. Npm modules do not have any restrictions. When there is any caching, there can be any importance given to the requirement statements. For the process to perform well, loading your modules is important before defining your server.

Leverage JavaScript Standard Style

Without proper set developing style, everything can turn upside down. Hence the best idea would be to set a proper company standard and get on with it. The best option would be to use JavaScript Standard Style. There are no particular decisions you need to handle. There would be no need to manage any .jscsrc or .jshintrc files.

While using JavaScript Standard Style, you need to ensure that you are setting a proper structure before moving on to the important tasks. It is essentially important to install the JavaScript Standard Style globally in the form of a Node command line program.

Enable Asynchronous Code efficiently

While using Node you can use the synchronous code to write CLI scripts or commands. This would no way be in relation to any of the web apps. Your Node developer should build proper web apps. To make sure that this happens, Async code would be the right way to avoid any blocking threads.

The Latest LTS Node.js version should come into play

You can achieve the best stability with the help of Long-Term Support (LTS). NVM allows you to shift between different Node.js versions.

Containers are here to stay!

Containers like Docker makes sure that deployment takes place in a more secure manner. You can take Docker’s lightweight images into consideration by running the applications when it is in isolation mode.

You can use containers to get used to immutable deployments by involving locally mirror production environments.

Your Apps should be highly secure

Making sure that your enterprise and customer data is increasingly important. It is important that you get a grip on Brute Force Protection, Node.js Security, Session Management and Security HTTP Headers.

Give attention to Semantic Versioning

While updating different packages without the help of SemVer, you could have broken your Node.js apps. It is vital to use Systematic versioning since your customers have to understand what are the new versions you should use. They should also understand what you expect when you update the new version.

Since npm makes use of SemVer at the time it installs more dependencies, you should give importance to it so that it avoids breaking different applications as soon as you are publishing your module.

Nodejs is actually not Java. Hence it is literally impossible to handle a number of errors at top levels with only one attempt. When Node can execute asynchronously with the help of an event loop, you can separate every error from the content of the error handler.

Node developers can solve this by providing a callback argument as an error. It is important for them to handle every error manually during every callback.

Never dodge with Error Events

When you can take care of error events, you can resolve them easily before there is any problem.

Since every Node objects or classes can take care of the observer pattern and in turn emit an error event, developers would not find it hard to look after the error events.

It is essentially important to avoid as many error events as possible. This would allow your code to flow flawlessly and efficiently. If you want to avoid error events, then you have to resolve them as quickly as possible.

Go Serverless!

There is a huge potential of growth for Serverless. It belongs to the open source community. Many new apps would be built on Serverless in the future. Since AWS Lambda was involved, Serverless Framework is the most important solution to deploy various AWS Lambda functions.

Node.js is not meant to render static assets

The best tip we can give you is to render all your static assets like Images and CSS. This has to happen on a standard web server such as Nginx. To manage your static content, your developer can arrange Nginx. This would in turn reduce the load present on your Node.js instance, thus increasing the performance.

Employment of Client-Side Rendering

There are many new client-side MVC frameworks such as BackboneJS and AngularJS. Developers can create more dynamic and one-page apps. The frameworks are in favour of APIs for sending JSON responses to the client instead of the server. If you can allow any Node.js to render server-side, then this would return an HTML page each time your developer requests it. When your Node.js environment makes use of client-side rendering, it can reduce your latency and bandwidth considerably.

Check if your app restarts automatically

Let’s say that you are following the best industry practices to manage your errors. The dependency error would slow down your app. This is where your process manager comes handy to ensure that the app is recovering in a graceful manner right from the runtime error. When the entire server is down, you are supposed to restart it again. You need a minimal downtime over here. Your application should restart soon after the server gets alive. To ensure that all this happens smoothly, you just need to restart your app in a better manner.

Engage Gzip Compression effectively

This software application is used mainly for file compression as well as decompression. Every clients and servers are in favor of gzip. When a server that is compatible with gzip requests for a resource, then it leads to prolonged time. Use gzip when you are responding to your clients. Ensure that you make different requests to more remote servers. These factors would improve the app performance incredibly.
