Node JS Best Practices to Create Stellar Apps
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 more 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 Node JS Express Best Practices development:
1. Organize the code sturdily
When you would go about working and developing complicated user interactions, you can see that your code would become more difficult in the case of debugging. There are a number of factors that you need to take into consideration such as the behavior of your bits and object literal pattern.
Ensure that you organize the code into smaller bits. Code organization isn’t an arduous task when you do it with your team of developers in an organized manner. 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 for 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 a private registry or a cache strategy to deal with temporary solutions. As far as we know, there are exactly four different kinds of strategies when you want to organize your code. You can get it done through a layer, toolbox, by its kind, and by component.
2. Don’t think twice to use Promises
Promises might be concurrency primitive. They are now a vital component in every recent programming language. fs API does not contain readFileAsync to return a Promise. Hence a module similar to promise all is required.
3. Don’t entertain Blocking Require
Place your every required statement at the file top. Owing to its synchronous nature, the execution will get blocked. A node consists of a simple module loading system. It makes use of the 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 requirement 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.
5. Enable Asynchronous Code efficiently
While using Node you can use the synchronous code to write CLI scripts or commands. This would in 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, the Async code would be the right way to avoid any blocking threads.
6. 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.
7. Containers are here to stay!
Containers like Docker make 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.
8. 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.
9. 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 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.
10. Never dodge Error Events
It is always advisable never to dodge any of the error events since it can cost you a lot. Every expert would suggest you never dodge any kind of error event. It’s extremely relevant advice, especially in recent days.
End Error would be ending a process and throwing an error message when you are starting your exception process path. With the Start Error, you can start any event subprocess when your exception would be flowing. Your Boundary Error would be ending your service or human task along with an event subprocess. You should take all these factors into consideration. The process flow would get diverted to your exception path. When you can take care of error events, you can resolve them easily before there is any problem.
Since every Node object or class 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.
11. Go Serverless!
There is a huge potential for 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.
12. 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.
13. 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 favor 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.
14. Check if your app restarts automatically
It is very much important to note if you are able to restart your app in an automatic manner. When you are going to restart your app, you would know how it would work.
If the user is going to be logged in on the server side with only one instance on the app, you need to act accordingly. There are plenty of ways to check if your app is working properly. App restarting is one of the most crucial and important ones among them. You should know how to work with your team. 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 in 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 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. Take care of that and ensure that you are on the right track with Node.js.
15. Engage Gzip Compression effectively
This software application is used mainly for file compression as well as decompression. Every client and server is in favor of gzip. When a server that is compatible with gzip requests for a resource, then it leads to a 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’s performance incredibly.
