NestJS enable cors in production

Question

I\'ve enabled CORS in my NestJS app following the official tutorial, so my main.ts looks like the following:

import { FastifyAdapter, NestFactory }

If you are running NestJs with graphql you will run into a problem where Apollo server will override the CORS setting see link. This below fixed the problem. I wasted 8 hrs of my life on this. :-( I hope you see this and you don't do that. see link and link

        GraphQLModule.forRoot({
            debug: process.env.NODE_ENV !== 'production',
            playground: process.env.NODE_ENV !== 'production',
            typePaths: ['./**/*.graphql'],
            installSubscriptionHandlers: true,
            context: ({req}) => {
                return {req};
            },
            cors: {
                credentials: true,
                origin: true,
            },
        }),

then in your main.ts:

        app.enableCors({
            origin: true,
            methods: 'GET,HEAD,PUT,PATCH,POST,DELETE,OPTIONS',
            credentials: true,
        });
