Installation

Setup is super easy. Clone the repository -

git clone https://github.com/sunilksamanta/node-mongoose-setup
cd node-mongoose-setup
npm install

Create an .env file at the root of your project with the following.

MONGO_URL=YOUR_MONGO_URL
PORT=5000[YOUR_DESIRED_PORT]
NODE_ENV=YOUR_APP_ENVIRONMENT[production/development]
JWT_SECRET=YOUR_JWT_SECRET_STRING

An example file .env.example is included.

Your project is ready. Now start the project.

npm start

Go to http://localhost:5000. You should see a default welcome page.

Your API base path is http://localhost:5000/api.

First create some accounts to get started with the authentication.

Authentication

JWT authentication is added in this project. User model is defined in models/User.js. For Register, Login, Logout use these urls —

    [POST] api/auth/register
    [POST] api/auth/login
    [GET] api/auth/logout

1. Controller, Model & Service oriented architecture

2. Auth with JWT & Db Store

3. Async/Await support

4. User Module

5. Post Module (Sample CRUD)

6. Media Upload

7. Centralized Http Response

8. Error Handler

9. .env support

10. Multi Environment config setup

11. Autobind Methods

12. Built in Pagination

Lets talk about the structure

We have 2 base classes — One for Controller and another for Service.

1. Controller.js

This base controller have the basic CRUD operations. To create a new controller just extend this base Controller class.

2. Service.js

This is the base Service class which includes the database operations. If you want to change the default behaviour of the services you can update this file.

How to Create new CRUD Module?

If you want to create a new Module say Post. Then you’ll have to create 4 basic files. One Controller, one Service, one Model and one route file. And add the new route in routes/index.js with desired url. There is a “Post” CRUD module included in this project for example.

    controllers/PostController.js
    models/Post.js
    services/PostService.js
    routes/post.js

Overriding Base class method

As an example if you see in the media Controller — the default delete method is overriden by its own class method as we have to delete the file from the file system also. So the overriden method is like bellow —

async delete(req, res, next) {
  const { id } = req.params;
  try {
      const response = await this.service.delete(id);
      // File Unlinking..
      if (response.data.path) {
          console.log("unlink item", response.data.path);
          fs.unlink(response.data.path, function (err) {
              if (err) {
                  console.log("error deleting file");
                  throw err;
              }
              console.log("File deleted!");
          });
      }
      return res.status(response.statusCode).json(response);
  }
  catch (e) {
      next(e);
  }
}
