I am trying to implement a JWT strategy for authentication in my nest application.
I am getting the following error tho
Unknown authentication strategy "jwt"
This is my code:
jwt.strategy.ts
import { Injectable } from "@nestjs/common";
import { PassportStrategy } from "@nestjs/passport";
import { Strategy } from "passport-local";
import { ExtractJwt } from "passport-jwt";
import { jwtConstants } from "./constants";
@Injectable()
export class JwtStrategy extends PassportStrategy(Strategy) {
constructor() {
super({
jwtFromRequest: ExtractJwt.fromAuthHeaderAsBearerToken(),
ignoreExpiration: false,
secretOrKey: jwtConstants.secret,
})
}
async validate(payload: any) {
console.log(payload);
return { userId: payload.sub, username: payload.username };
}
}
My Authentication Module:
authentication.module.ts
import { Module } from '@nestjs/common';
import { AuthenticationService } from './authentication.service';
import { UsersModule } from 'src/users/users.module';
import { PassportModule } from '@nestjs/passport';
import { LocalStrategy } from './local.strategy';
import { JwtModule } from '@nestjs/jwt';
import { jwtConstants } from './constants';
import { JwtStrategy } from './jwt.strategy';
@Module({
providers: [
AuthenticationService,
LocalStrategy,
JwtStrategy
],
imports: [
UsersModule,
PassportModule,
JwtModule.register({
secret: jwtConstants.secret,
signOptions: { expiresIn: "1d" },
})
],
exports: [AuthenticationService]
})
export class AuthenticationModule {}
And I am trying to use it in the following controller:
users.controller.ts
import { Controller, Post, Body, Put, Param, Get, UseGuards } from '@nestjs/common';
import { User } from './user.entity';
import { UsersService } from './users.service';
import { JwtAuthGuard } from 'src/authentication/jwt-auth.guard';
@Controller('users')
export class UsersController {
constructor(private readonly usersService: UsersService) {}
@UseGuards(JwtAuthGuard)
@Get()
async getAll(){
return this.usersService.findAll();
}
}
The Users Module looks like this:
users.module.ts
import { Module } from '@nestjs/common';
import { TypeOrmModule } from '@nestjs/typeorm';
import { User } from './user.entity';
import { UsersService } from './users.service';
import { UsersController } from './users.controller';
@Module({
imports: [TypeOrmModule.forFeature([User])],
providers: [UsersService],
controllers: [UsersController],
exports: [UsersService]
})
export class UsersModule {}
JwtAuthGuard
is just a class that extends from AuthGuard('jwt')
I have follow the nestjs authentication guide from the official docs, but cant get it running in my UsersModule
The issue was that autoimport imported Strategy from the wrong package
import {Strategy} from "@nest/passport-local";
instead of
import { Strategy } from "passport-jwt";
