Often, the Web Application process that involves JavaScript is accompanied by Nodejs, an Open-source, cross-platform JavaScript runtime environment. Nodejs Development is one of the most popular Web Development Framework in recent times; because of Nodejs, many Web developers write code in JavaScript without the browser and build server-side web apps that are lightweight, secure, and robust.
“A good start to a project is half the battle,” said the wise man. Laying out a Nodejs Development project structure practically is one of the tough parts of the Development process and the most delicate process.
In this article, We’ll focus on the basics of Nodejs Architecture and share some project best practices for Nodejs Web Development.
Why is Project Architecture important?
As mentioned above, having a good starting point in Nodejs Architecture is vital for the life spent on the project and how you will tackle future changes. The main objectives of any Nodejs Project Architecture are to help you with-
- Readable and clean codes
- Helps to avoid repetition
- Can add new features without disturbing any existing codes.
8 best practices for Nodejs Development Project structure
The Nodejs Project architecture best practices can work as a Cheatsheet to assist you with your upcoming project.
1. Create a folder structure for your project
We all know how accurate every part needs to be in Web Application. If you want to bring the best in the market, then an A folder is ideal for classifying basic elements. Practically, we have to make a very important separation which leads us to the next rule.
2. Business Logic and API Routes
Frameworks such as Express.js are amazing. They provide us with improbable features for managing requests, Views, and routes. With such guidance, it might be fascinating for us to put our Business logic in API routes. This will make them into bulk; unified Sections will reveal themselves unmanageable and prone to decomposition.
At this very moment, you might be questioning ways to solve this problem and how you can put your market logic clearly and intelligently. We'll dive into this in another rule.
3. Practice a service layer
This is the place where all our Market logic should live. It’s a combination of classes, each with its system, that will be performing our App’s core logic. The only thing that you should ignore in this layer is the one that accesses the database; The data access layer should control that.
4. Workers Thread
Worker threads are beneficial for working CPU-intensive JavaScript methods. However, Do not try to put them on input and output intensive services. Nodejs manages async input/ output exceedingly more efficiently than you could with the operators.
5. Child Processes
Nodejs, being single-threaded, can generate child processes to take responsibility for projects. A child process begins with the insurance on the CPU, similar to memory utilization, which utilizes your machine’s bound support. It is important not to hold more child processes that you hold essences in your machine.
6. Use Dependency injection
Nodejs Development is jammed with amazing features and accessories which makes our lives easier. Although we know working on dependencies can get troublesome most of the time due to difficulties with testability and code management.
Don’t worry; we have solutions for that, named dependency injection.
Dependency injection is a Custom software development pattern in which one or more dependencies can be injected or transferred into a dependent object.
You can do many things by using dependency injection in the Nodejs Web Application:
- You can accelerate your gif flow
- You can avoid useless modules coupling
- You can Streamline the unit testing process
7. Unit Testing
Now that we know about Dependency injection and have got it under our belt, we can also perform unit testing for our project. Testing is a really major step when it comes to improving our application. The flow of the project, not just the final result- Relies on buggy code which can slow down the process and create more difficulties.
A most common way to test Web applications is to examine them by parts, The purpose of which is to separate code and its correctness. These are the benefits of this approach:
- Advanced code quality
- Bugs are found earlier
- Reduce cost.
8. Another layer for third-party services call
Usually, In our web Application, We may need to request a third-party service to reclaim certain data or bring out some assistance. And still, very repeatedly, if we don’t leave this order into another layer. We might progress into an out-of-control piece of code that has become too substantial to handle.
A usual way to settle this issue is to rehearse the pub/ Sub Pattern. This device is a messaging pattern Where we have things to convey messages called publishers, and objects making them called Subscribers.
The Publish-subscribe models enable event-driven architectures while improving performance, reliability, and scalability.
