Questions tagged [nestjs-jwt]

This package provides JSON Web Token (JWT) utilities and helps create tokens for use in authentication and authorization of web requests to your NestJS application. It contains a JwtModule that exposes a single JwtService provider to sign, verify and decode JWT tokens, either synchronously or asynchronously. The JwtService is configured with options (via JwtModuleOptions) that correspond to config of the NodeJS jsonwebtoken package used underneath.

Provides JWT utilities module for NestJS based on the jsonwebtoken package.

From the documentation:

The @nestjs/jwt package is a utility package that helps with JWT manipulation. The passport-jwt package is the Passport package that implements the JWT strategy and @types/passport-jwt provides the TypeScript type definitions.

@Module({
 imports: [JwtModule.register({ secret: 'hard!to-guess_secret' })],
 providers: [...],
})

export class AuthService {
 constructor(private readonly jwtService: JwtService) {}
}
