@Module({
  imports: [AuthManager],
  providers: [AuthLoginInterceptor]
})
export class AppModule {
}

USING DECORATORS

Inject and use the decorators in your controllers:

import { Controller} from '@nestjs/common';
import { Login, Redirect, SessionInfo } from '../auth-manager/module';

@Controller('v1/auth')
export class AuthController {

  @Login('login')
  async login() {}

  @Redirect('redirect')
  async redirectToDashboard(){}

  @SessionInfo('sessionInfo')
  async getSessionInfo() {}

}

USING INTERCEPTORS

Inject and use the decorators in your controllers:

import { Controller, UseInterceptors }                                               from '@nestjs/common';
import { Login, Redirect, SessionInfo }                                              from '../auth-manager/module';
import { AuthLoginInterceptor, AuthRedirectInterceptor, AuthSessionInfoInterceptor } from './auth.interceptors';

@Controller('v1/auth')
export class AuthController {

  @UseInterceptors(AuthLoginInterceptor)
  @Get('login')
  async login() {
    //your application functionality here
  }

  @UseInterceptors(AuthRedirectInterceptor)
  @Post('redirect')
  async redirectToDashboard() {
    //your application functionality here
  }

  @UseInterceptors(AuthSessionInfoInterceptor)
  @Get('sessionInfo')
  async getSessionInfo() {
    //your application functionality here
  }

}

Protecting Routes

Use the AuthGuard to protect routes that require authentication:

import { Controller, UseGuards, UseInterceptors } from '@nestjs/common';
import { AuthGuard } from './auth.interceptors';

// Guard at Controller level
@UseGuards(AuthGuard)
@Controller('v1/produts')
export class ProductsController {
  @Get()
  async getProducts() {
    //your application functionality here
  }
}

import { Controller, UseGuards, UseInterceptors } from '@nestjs/common';
import { ValidateSession } from './auth.decorators';


@Controller('v1/produts')
export class ProductsController {

  // Guard at function level
  @ValidateSession()
  @Get()
  async getProducts() {
    //your application functionality here
  }
}
