Potential solutions:
- If JWT_MODULE_OPTIONS is a provider, is it part of the current JwtService?
- If JWT_MODULE_OPTIONS is exported from a separate @Module, is that module imported within JwtService?

Im trying to use a middleware to authenticate users when entering some routes
auth.middleware.ts
import { Request, Response, NextFunction } from 'express';
import { JwtService } from '@nestjs/jwt';
@Injectable()
export class AuthMiddleware implements NestMiddleware {
constructor(private jwtService: JwtService) {}
use(req: Request, res: Response, next: NextFunction) {
const headerToken = req.headers.authorization;
if (!headerToken) {
return res.status(401).send({ error: 'No token provided' });
}
const [scheme, token] = headerToken.split(' ');
if (!token) {
return res.status(401).send({ error: 'Token error' });
}
try {
const user = this.jwtService.verify(token);
req.user = user.id;
return next();
} catch (error) {
return res.status(401).send({ error: 'Invalid token' });
}
}
}```
auth.module.ts
import { Module } from '@nestjs/common';
import { JwtModule, JwtService } from '@nestjs/jwt';
import { AuthMiddleware } from './auth.middleware';
@Module({
imports: [
JwtService,
JwtModule.register({
secret: process.env.JWT_SECRET,
signOptions: { expiresIn: '1day' },
}),
],
providers: [AuthMiddleware],
exports: [AuthMiddleware],
})
export class AuthModule {}
im not 100% sure that the middleware should have a module bu without it, the middleware won't work
app.module.ts
import { MiddlewareConsumer, Module, NestModule } from '@nestjs/common';
import { AppController } from './app.controller';
import { AppService } from './app.service';
import { PrismaModule } from './prisma.module';
import { UsersModule } from './users/users.module';
import { ConnectionsModule } from './connections/connections.module';
import { MessagesModule } from './messages/messages.module';
import { AuthModule } from './auth/auth.module';
import { AuthMiddleware } from './auth/auth.middleware';
@Module({
imports: [
PrismaModule,
UsersModule,
ConnectionsModule,
MessagesModule,
AuthModule,
],
controllers: [AppController],
providers: [AppService],
})
export class AppModule implements NestModule {
configure(consumer: MiddlewareConsumer) {
consumer.apply(AuthMiddleware).forRoutes('users');
}
}
the documentation says that i need to pass those options here for the middleware to work
Is this my concern or is it a bug from @nestjs/jwt, and if it is a bug that i created, how do i fix it?

CodePudding user response：
Remove JwtService from your AuthModule's imports. Providers never belong in the imports array, and because you've already imported JwtModule, you don't need to add JwtService to any module, the JwtModule` already exposes access to it.

now it gives me this error
if i try to import the JwtModule os the JwtService on the appModule it returns me the same error from before
the problem for me is: i need to import the JwtService for using it in the authenticate middleware, if i don't import, it says that i should import it. And if i import it returns me the error about the JWT_MODULE_OPTIONS
