@next-nest-auth/nestauth/src/nestauth-jwt.strategy.ts

NestAuth is an authentication solution for NestJS applications, designed to handle user login, session management, and token-based authentication (JWT). It integrates seamlessly with Next.js and other frontends to provide a unified authentication system,

import { ExtractJwt, Strategy } from "passport-jwt";
import { PassportStrategy } from "@nestjs/passport";
import { Inject, Injectable } from "@nestjs/common";
import { JwtPayload } from "jsonwebtoken";
import * as macaddress from "macaddress";

@Injectable()
export class NestAuthJwtStrategy extends PassportStrategy(Strategy) {
  constructor(@Inject("JWT_SECRET") jwtSecret: string) {
    super({
      jwtFromRequest: ExtractJwt.fromAuthHeaderAsBearerToken(),
      ignoreExpiration: false,
      secretOrKey: jwtSecret,
    });
  }

  async validate(payload: JwtPayload) {
    return {
      userId: payload.sub,
      macId: payload.macId ?? (await macaddress.one()),
      email: payload.email,
      role: payload.role,
      name: payload.name,
      username: payload.username,
