Getting Started

Register the module in app.module.ts

import { Module } from '@nestjs/common';
import {
  KeycloakConnectModule,
  ResourceGuard,
  AuthGuard,
} from 'nest-keycloak-connect';

@Module({
  imports: [
    KeycloakConnectModule.register({
      authServerUrl: 'http://localhost:8080/auth',
      realm: 'master',
      clientId: 'my-nestjs-app',
      secret: 'secret',
      // optional if you want to retrieve JWT from cookie
      cookieKey: 'KEYCLOAK_JWT'
    }),
  ],
  providers: [
    // These are in order, see https://docs.nestjs.com/guards#binding-guards
    // for more information

    // This adds a global level authentication guard, you can also have it scoped
    // if you like.
    //
    // Will return a 401 unauthorized when it is unable to
    // verify the JWT token or Bearer header is missing.
    {
      provide: APP_GUARD,
      useClass: AuthGuard,
    },
    // This adds a global level resource guard, which is permissive.
    // Only controllers annotated with @Resource and methods with @Scopes
    // are handled by this guard.
    {
      provide: APP_GUARD,
      useClass: ResourceGuard,
    },
  ],
})
export class AppModule {}

In your controllers, simply do:

import { Resource, Scopes } from 'nest-keycloak-connect';
import { Controller, Get, Delete, Put, Post, Param } from '@nestjs/common';
import { Product } from './product';
import { ProductService } from './product.service';

@Controller()
@Resource(Product.name)
export class ProductController {
  constructor(private service: ProductService) {}

  @Get()
  @Scopes('View', 'View All')
  async findAll() {
    return await this.service.findAll();
  }

  @Get(':code')
  @Scopes('View')
  async findByCode(@Param('code') code: string) {
    return await this.service.findByCode(code);
  }

  @Post()
  @Scopes('Create')
  async create(@Body product: Product) {
    return await this.service.create(product);
  }

  @Delete(':code')
  @Scopes('Delete')
  async deleteByCode(@Param('code') code: string) {
    return await this.service.deleteByCode(code);
  }

  @Put(':code')
  @Scopes('Edit')
  async update(@Param('code') code: string, @Body product: Product) {
    return await this.service.update(code, product);
  }
}
