res.setHeader is not a function When i add new FastifyAdapter()

[samuelhalim1]

Describe the bug If i put new FastifyAdapter() like this const app = await NestFactory.create<NestFastifyApplication>( AppModule, new FastifyAdapter(), )

it will return error when i access localhost:3000

res.setHeader("Cache-Control", "no-cache, no-store, max-age=0, must-revalidate"); ^ TypeError: res.setHeader is not a function

Is it can't support fastify adapter? Because i serve static files from my server use the fastify adapter

Version

• next.js: 13.0.6
• nest: 9.0.0
• nest-next: 10.0.0

It works correctly with the fastify adapter. This library doesn't actually make any calls to setHeader on the response, so I think that your problem is coming from your application code or perhaps nextjs. Whre does the stacktrace say that the setHeader call is?

Even when i try to add FasitifyAdapter on this Example https://github.com/yakovlev-alexey/nest-next-example

The error is same.. So i assume that the error isn't came from my next or nest app

just make sure u guys know @yakovlev-alexey @kyle-mccarthy

[samuelhalim1]

add some information, that i use

Version

• @nestjs/platform-fastify: ^9.2.1

[kyle-mccarthy]

So it looks like this error is coming from next. Notice that the path /Users/Development/test/node_modules/.pnpm/[[email protected]_biqbaboplfbrettd7655fr4n2y](mailto:[email protected]_biqbaboplfbrettd7655fr4n2y)/node_modules/next/dist/server/base-server.js:1047:17 points to the base server file in the next package.

Since next 13 is effectively still in beta, I don't plan to add support for it until it is stabilized. You should be able to continue to use next 12 without issue.

Allrite.. so right now the project is running With Version

• next: ^12.3.4
• @nestjs/platform-fastify: ^8.0.0

But when i upgrade the platform-satisfy version to ^9.2.1.. It just show a blank page Is it doesn't support 9.2.1 version?

I try next 13.4.x, 12.4.6, platform-fastify 8, 9.x All of the combination does not work. I try to do the setup with express, it works.

import { NestFactory } from '@nestjs/core';
import { AppModule } from './app.module';
import {
  FastifyAdapter,
  NestFastifyApplication,
} from '@nestjs/platform-fastify';
import { fastifyStatic } from 'fastify-static';
import { join } from 'path';
import { RenderService } from 'nest-next';
import secureSession from '@fastify/secure-session';
import session from 'express-session';
async function bootstrap() {

  const usefastify = false;
  if (usefastify) {

    const app = await NestFactory.create<NestFastifyApplication>(
      AppModule,
      new FastifyAdapter(),
    );
 
    app.setGlobalPrefix(`/absproxy/5000`);

    await app.register(secureSession, {
      secret: 'averylogphrasebiggerthanthirtytwochars',
      salt: 'mq9hDxBVDbspDR6n',
    });
   
    await app.listen(5000);
  }
  else {
    const app = await NestFactory.create(AppModule);
    app.setGlobalPrefix(`/absproxy/5000`);

    const service = app.get(RenderService);

    app.use(
      session({
        secret: 'my-secret',
        resave: false,
        saveUninitialized: false,
      }),
    );
    await app.listen(5000);
  }

  /* if (module.hot) {
     module.hot.accept();
     module.hot.dispose(() => app.close());
   }*/
}
bootstrap();
