Getting Started

To register OauthModule with your app, import the module inside AppModule.

Static Registration

OauthModule is added to global scope by default.

import { Module } from '@nestjs/common';
import { OauthModule } from 'nest-social-auth'

@Module({
  imports: [
    OauthModule.register({
      isGlobal: true,
      default: 'facebook',
      clients: {
        facebook: {
            clientId:process.env.FACEBOOK_APP_ID,
            clientSecret:process.env.FACEBOOK_APP_SECRET
        },
        google: {
          clientId:process.env.GOOGLE_CLIENT_ID,
          clientSecret:process.env.GOOGLE_CLIENT_SECRET
      },
      linkedin: {
          clientId:process.env.LINKEDIN_CLIENT_ID,
          clientSecret:process.env.LINKEDIN_CLIENT_SECRET
      }
    })
  ],
  controllers: [],
  providers: [],
})
export class AppModule { }

Recommended Way

Use ConfigModule provided by NestJS to load configurations. To learn about ConfigModule, click here.

#1. Create filesystem.ts file

import { registerAs } from "@nestjs/config";
import { OauthOptions } from "libs/oauth/src/interfaces";

export default registerAs(
  "oauth",
  () =>
    ({
      isGlobal: true,
      default: "facebook",
      clients: {
        facebook: {
          clientId: process.env.FACEBOOK_APP_ID,
          clientSecret: process.env.FACEBOOK_APP_SECRET,
        },
        google: {
          clientId: process.env.GOOGLE_CLIENT_ID,
          clientSecret: process.env.GOOGLE_CLIENT_SECRET,
        },
        linkedin: {
          clientId: process.env.LINKEDIN_CLIENT_ID,
          clientSecret: process.env.LINKEDIN_CLIENT_SECRET,
        },
      },
    } as OauthOptions)
);

#2. Register ConfigModule

import { Module } from "@nestjs/common";
import filesystem from "@config/fileystem";
import { ConfigModule } from "@nestjs/config";

@Module({
  imports: [
    ConfigModule.forRoot({
      isGlobal: true,
      expandVariables: true,
      load: [filesystem],
    }),
  ],
  controllers: [],
  providers: [],
})
export class AppModule {}

#3. Register Async StorageModule Add following snippet to the imports array. ConfigService is importable from @nestjs/config module.

OauthModule.registerAsync({
  isGlobal: true,
  imports: [ConfigModule],
  useFactory: (config: ConfigService) => config.get("oauth"),
  inject: [ConfigService],
});

Driver Configuration

The best part about this package is the simplicity that it provides while working across different social login platforms. Every driver follow a simple and consistent API.

Currently the package supports login authentication for facebook,google and linkedin.

Driver Name: Facebook

Configuration:

{
    clientId:process.env.FACEBOOK_APP_ID,
    clientSecret:process.env.FACEBOOK_APP_SECRET
    }

facebook driver expects two parameters to authenticate a token. You can get the FACEBOOK_APP_ID, FACEBOOK_APP_SECRET by creating a developer account at facebook and enabling auth 2.0. Learn more about it here.

Driver Name: Google

Configuration:

{
    clientId:process.env.GOOGLE_APP_ID,
    clientSecret:process.env.GOOGLE_APP_SECRET
    }

google driver expects two parameters to authenticate a token. You can get the GOOGLE_APP_ID, GOOGLE_APP_SECRET by creating a developer account at google and enabling auth 2.0. Learn more about it here.

Driver Name: Linkedin

Configuration:

{
    clientId:process.env.LINKEDIN_APP_ID,
    clientSecret:process.env.LINKEDIN_APP_SECRET
    }

linkedin driver expects two parameters to authenticate a token. You can get the LINKEDIN_APP_ID, LINKEDIN_APP_SECRET by creating a developer account at linkedin and enabling auth 2.0. Learn more about it here.

To serve the file objects from your project, have a look at serve-static module by NestJS.
