Please also don’t forget about how the testability of our application will decrease, with consequently longer development times.
But this will quickly make them into giant, monolithic blocks that will reveal themselves to be unmanageable, hard to read, and prone to decomposition. With such support, it might be tempting for us to put our business logic into our API routes. They provide us with incredible features for managing requests, views, and routes. Separate business logic and API routesįrameworks like Express.js are amazing. In particular, we want to define a very important separation, which brings us to our next rule. Create a folder structure for your projectĮverything has to have its place in our application, and a folder is the perfect place to group common elements. The Node.js project architecture best practices outlined below can serve as a cheat sheet to help you establish the perfect architecture flow for your next project. Now we can discuss what I usually refer to as the application structure flow, a set of rules and common practices to help improve the Node.js developer experience. Add new features without disrupting existing codeīest practices for Node.js project structure.Write reusable pieces of code across our application.The main objective of any Node.js project structure is to help you: Difficulty implementing new features without messing up existing code.Useless repetition, which makes code harder to maintain and manage.Unreadable and messy code, which prolongs the development process and makes the product itself harder to test.A bad, messy project architecture often leads to: Having a good starting point when it comes to our project architecture is vital for the life of the project itself and how you will be able to tackle changing needs in the future. Use another layer for third-party services calls.Establish a scripts folder for long npm scripts.
Use a config folder to organize configuration files.Create a folder structure for your project.Best practices for Node.js project structure.We’ll cover the basics of application architecture in general and share some project structure best practices to help you organize your Node.js apps. In this tutorial, we’ll focus on Node.js project structure. Laying out a project structure in a practical way is one of the hardest parts of the development process and, indeed, a delicate process. And I can’t think of any quote that would better describe the situation every developer encounters when starting a new project.
