passport.js not working with nestjs (fastify)

Question

I am using fastifyAdapter instead of expressAdapter on nestjs. it gives me following error-

TypeError: res.setHeader is not a function
at GoogleStrategy.strategy.redirect

Answer 1

Unfortunately, Fastify is not compatible with passport.js Nest.js module

fastify has different redirect and functions in general from express, so not all middlewares are compatible: see for example redirect differences from docs
