Nestjs-google-auth NPM

Google Login Package for NestJS

A simple and reusable package for integrating Google login with NestJS using passport-google-oauth2. This package simplifies the process of authenticating users with Google by providing the strategy and module, leaving the control of user flow and logic up to you.

Features

Easy-to-use package for Google login integration with NestJS
Pre-configured passport-google-oauth2 strategy
Customizable user validation logic (you implement the controller and service)

Installation

Install the package via npm:
```
npm install nestjs-google-auth
```
Install the necessary Passport dependencies if they are not already installed
```
npm install passport passport-google-oauth2
```
Install the type definitions for Passport (for TypeScript support):
```
npm install --save-dev @types/passport
```
Install the express-session and passport if you are using sessions (if the package is not already installed):
```
npm install passport express-session
```

Add environment variables to your .env file:

GOOGLE_CLIENT_ID=your-google-client-id
GOOGLE_CLIENT_SECRET=your-google-client-secret
GOOGLE_CALLBACK_URL=your-google-callback-url

Usage

Import the GoogleAuthModule & GoogleAuthController to your AppModule:

@Module({
imports: [
GoogleAuthModule.forRoot({
  clientID: process.env.GOOGLE_CLIENT_ID,
  clientSecret: process.env.GOOGLE_CLIENT_SECRET,
  callbackURL: process.env.GOOGLE_CALLBACK_URL,
  scope: ['profile', 'email'],
  session: false,
}),
],
controllers: [AppController, AuthController],
providers: [AppService],
})
export class AppModule {}

If you are using sessions, you should configure the session in your main.ts file using express-session:

  app.use(
    session({
        secret: 'your-secret-key',
        resave: false,
        saveUninitialized: true,
    }),
);

    app.use(passport.session());
