Prerequisites

Before getting started, ensure that you have the following prerequisites:

• Node.js (version 14 or above)
• npm or yarn package manager
• NestJS (installed globally or as a project dependency)
• A database (e.g., PostgreSQL, MySQL, MongoDB) supported by your NestJS application
• Prisma client set up and connected to your database

Installation

1. Clone this repository to your local machine:

git clone https://github.com/SujoySust/Multi-Auth-with-Jwt-Passport-in-NestJS.git

2. Navigate to the project directory:

cd nestjs-simple-auth-restapi

3. Install the dependencies:

npm install or yarn install

4. Configure your database connection by updating the configuration file: prisma/schema.prisma

5. Run the database migrations to create the necessary tables:

npm prisma db push or yarn prisma db push

Usage

To use the authentication setup provided by JwtAuthGuard, follow these steps:

For User Gaurd: Include the JwtAuthGuard() in your route or controller using the @UseGuards() decorator:

import { Controller, Get, UseGuards } from '@nestjs/common';
import { User } from '../../models/db/user.model';
import { UserEntity } from '../../../libs/decorators/user.decorator';
import { JwtAuthGuard } from '../../../libs/auth/auth.gaurd';

@UseGuards(JwtAuthGuard())
@Controller()
export class UserController {
  @Get('/profile')
  async profile(@UserEntity() user: User): Promise<User> {
    return user;
  }
}

For Staff Gaurd: Include the JwtAuthGuard('staff') in your route or controller using the @UseGuards() decorator:

@UseGuards(JwtAuthGuard('staff'))
@Controller('staff')
export class StaffController {
  @Get('/profile')
  async profile(@UserEntity() staff: Staff): Promise<Staff> {
    return staff;
  }
}

Configuration

To configure the authentication setup, you may need to modify the following files:

config/jwt.config.ts: Adjust the JWT secret, expiration time, and other configurations to suit your needs.

Make sure to review and modify the configurations according to your specific application requirements.
