NestJS Fastify Authentication

Question

So I replaced ExpressJS with Fastify, but my problem is Nest-Passport doesn't support fastify, do we have an alternative for Nest-Passport? or any solutions on how to secure RestAPI in nestJS using a token?

Answer 1

There's no immediate Fastify NestJJS authentication package I'm aware of (I'm sure there's something out there), but I do have a sample of JWT authentication with Fastify and NestJS without Passport. The idea is to make use of Nest's @nestjs/jwt package or just jsonwebtoken directly, and create the auth tokens with that instead of delegating to Passport. This is actually the kind of approach I prefer, as I find Passport to be a bit too mystical sometimes.

Answer 2

I dont kown if this is the correct manner. But if I change the default jwt extractor

ExtractJwt.fromAuthHeaderAsBearerToken

(described within the doc ) by a custom one it works.

const fromFastifyAuthHeaderAsBearerToken = (request: FastifyRequest): string => {
const auth = request.headers['authorization'];
const token = auth?.split(' ')[1];
return token;
}
