Setting Up The Directory Structure

Lecture 359:- Setting Up The Directory Structure

Setting up a directory structure for an API-based project requires some initial planning to determine what the API will do and what its endpoints will be. The following is an example of how to structure an API directory:

bashCopy code

/api  /v1    /controllers      userController.js      postController.js      commentController.js    /models      user.js      post.js      comment.js    /routes      userRoutes.js      postRoutes.js      commentRoutes.js    /middlewares      auth.js    /utils      errorHandlers.js      responseHandlers.js

The api folder is where all API-related files will be stored. Inside the api folder, there is a v1 folder that signifies the version of the API. This can be updated to v2, v3, and so on, as the API evolves.

The controllers folder holds the controllers that contain the application's business logic. These controllers handle requests and responses and communicate with the models.

The models folder holds the data models, which represent the data that the application will be working with.

The routes folder holds the routing logic. Each endpoint will have its own file, which will handle the logic for that particular endpoint.

The middlewares folder holds the middleware functions that will be used to authenticate users, validate requests, and handle errors.

The utils folder holds the utility functions that are used throughout the application, such as error handlers and response handlers.

With this directory structure in place, it becomes easier to navigate and manage an API-based project.
