I want to implement a distributed authentication library to use it on several projects. The library should implement JWT authentication method. The code is as follows:
jwt.strategy.ts
import {ExtractJwt, Strategy} from 'passport-jwt';
import {PassportStrategy} from '@nestjs/passport';
import {Injectable} from '@nestjs/common';
import {JwtPayload, User} from './interfaces';
import {ConfigService} from "./config.service";
@Injectable()
export class JwtStrategy extends PassportStrategy(Strategy, 'jwt') {
constructor(private readonly configService: ConfigService) {
super({
jwtFromRequest: ExtractJwt.fromAuthHeaderAsBearerToken(),
secretOrKey: configService.get('secretOrPrivateKey'),
});
}
async validate(payload: JwtPayload): Promise<User> {
return {
uuid: payload.uuid,
email: payload.email,
}
}
}
jwt.auth.module.ts:
import {Module, DynamicModule} from '@nestjs/common';
import {JwtModule} from '@nestjs/jwt';
import {JwtStrategy} from './jwt.strategy';
import {PassportModule} from '@nestjs/passport';
import {ConfigService} from "./config.service";
import {JwtOptions} from "./interfaces/jwt.options";
@Module({
})
export class JwtAuthModule {
static forRoot(jwtOptions): DynamicModule {
return {
module: JwtAuthModule,
imports: [
// JwtModule.register(jwtOptions),
// PassportModule.register({defaultStrategy: 'jwt'}),
],
providers: [
JwtStrategy,
{
provide: ConfigService,
useValue: new ConfigService(jwtOptions),
}
],
exports: [ConfigService, JwtStrategy]
};
}
}
and I have imported this in my app.module.ts
:
import { Module, NestModule, HttpModule } from '@nestjs/common';
import { MongooseModule } from '@nestjs/mongoose';
import { environment } from './environments';
import { AuthModule } from './auth/auth.module';
import { PermissionModule } from './permission/permission.module';
import {JwtAuthModule} from '@pe/nest-kit';
import {JwtModule} from '@nestjs/jwt';
import {PassportModule} from '@nestjs/passport';
@Module({
imports: [
JwtModule.register(environment.jwtOptions),
PassportModule.register({defaultStrategy: 'jwt'}),
JwtAuthModule.forRoot(environment.jwtOptions),
HttpModule,
AuthModule,
PermissionModule,
MongooseModule.forRoot(environment.mongodb),
],
})
export class ApplicationModule implements NestModule {
configure() {
}
}
however, each time I try to open project url, I'm getting an error:
[Nest] 27645 - 24.10.2018, 15:23:26 [ExceptionsHandler] Unknown authentication strategy "jwt" +4119ms Error: Unknown authentication strategy "jwt" at attempt (/home/user/workspace/permissions/node_modules/passport/lib/middleware/authenticate.js:187:37) at authenticate (/home/user/workspace/permissions/node_modules/passport/lib/middleware/authenticate.js:363:7) at Promise (/home/user/workspace/permissions/node_modules/@nestjs/passport/dist/auth.guard.js:83:3) at new Promise () at /home/user/workspace/permissions/node_modules/@nestjs/passport/dist/auth.guard.js:75:83 at MixinAuthGuard.

what am I doing wrong?
Are you sure that you have added all needed packages? Try to go through the authentication documentation https://docs.nestjs.com/techniques/authentication it explains very well how to deal with JWT.
