How to use

1. Install the package

npm install dewmyth-auth-nestjs-mongo

2. Go to the NestJS module where you want to use the package and import the module and import the AuthModule from the library

import { AuthModule } from 'dewmyth-auth-nestjs-mongo';

3. Add the AuthModule to the imports array of the module with the mongoUri property set to the uri of the mongo database you want to connect to

  imports: [
    AuthModule.forRoot({
      mongoUri:
        'your-mongo-uri', // The uri to connect to the mongo database
    }),
  ],

4. Now you can use the AuthService in your module

5. Import the AuthService from the library to whatever the sevice or controller you want to use it in

import { AuthService } from 'dewmyth-auth-nestjs-mongo';

6. Then inject the AuthService into the constructor of the service or controller

  constructor(
    private readonly authService: AuthService,
  ) {}

7. Now you can use the AuthService to create a user and login a user

Create a User

A basic function that will accept the user's email, password, and username and return the created user. The created user will be saved on the mongodb database under the users collection. The password will be hashed using bcrypt before saving it to the database.

  async createUser() {
    const newUser = await this.authService.createUser({
      email: '[email protected]'
      password: 'samplePassword',
      username: 'sampleUsername',
    });
  }

Login a User

A basic function that will accept the user's email and password and return the logged user. The function will check if the user exists in the database and if the password matches the hashed password in the database. If the user exists and the password matches, the user will be logged in and a token will be returned.

  async loginUser() {
    const loggedUser = await this.authService.loginUser({
      email: '[email protected]'
      password: 'samplePassword',
    });
  }

Optionally you can pass the JWT secret and the JWT expiration time in the options object. The default JWT secret

  async loginUser() {
    const loggedUser = await this.authService.loginUser({
      email: '[email protected]'
      password: 'samplePassword',
    },
  'sampleSecret', // The JWT secret
  '1h', // The JWT expiration time, Please refere JWT documentation for more information
    );
  }
