Description

I wanted to set up a small graphql endpoint for the frontend to use (for forms), but I couldn't get apollo-server-micro to work. This is the error I got:

Cannot use GraphQLSchema "[object GraphQLSchema]" from another module or realm.

Ensure that there is only one instance of "graphql" in the node_modules
directory. If different versions of "graphql" are the dependencies of other
relied on modules, use "resolutions" to ensure only one version is installed.

https://yarnpkg.com/en/docs/selective-version-resolutions

Duplicate "graphql" modules cannot be used at the same time since different
versions may have different capabilities and behavior. The data from one
version used in the function from another could produce confusing and
spurious results.

This happens when initializing the ApolloServer instance. If I run the file using node.js directly it does not throw an error on the same line, so I think Gatsby may be doing some loader magic that breaks things that need the graphql module, such as apollo server. I think this magic should be dispelled for Gatsby Functions.

I have verified that indeed there is only one graphql module in my node_modules using yarn why graphql and manually checking.

Reproduction Link

https://codesandbox.io/s/quirky-thompson-llnhk?file=/src/api/graphql.js

Steps to Reproduce

1. Install apollo-server-micro and micro
2. Create a src/api/graphql.js with a basic graphql server (see example below)
3. Attempt to load /api/graphql in browser

import { ApolloServer, gql } from "apollo-server-micro"

const typeDefs = gql`
  type Query {
    sayHello: String
  }
`

const resolvers = {
  Query: {
    sayHello(parent, args, context) {
      return "Hello World!"
    }
  }
}

// this is the line that throws
const apolloServer = new ApolloServer({ typeDefs, resolvers, debug: true })

export default async function graphqlEndpoint(req, res) {
  await apolloServer.start()
  const handler = apolloServer.createHandler()

  return handler(req, res)
}

Expected Result

The graphql endpoint would show

Actual Result

Error when executing function "/.../src/api/graphql.ts":

Finally had some time to do some digging into this and it seems like an issue with webpack and the fact that apollo-server doesn't publish ESM versions yet, but the graphql module does: apollographql/apollo-server#4983 and apollographql/apollo-server#5627

It seems like if gatsby wants to support apollo-server in functions there needs to be a way to customize the functions webpack config. I verified if I manually define extensions: ['ts', 'mjs', 'js', '...'] in the functions webpack config that it works. Is there a plan to support customizing the webpack config?

[LekoArts]

The comments apollographql/apollo-server#4983 (comment) & apollographql/apollo-server#5627 (comment) seem to suggest though that this would (also) be fixed with adding an alias. Gatsby doesn't support ESM right now so you can't use pure ESM packages out of the box just yet.

[mariusc23]

Yeah, alias should work too. Just need a way to configure the functions webpack config. The onCreateWebpackConfig hook seems to be only for non-functions webpack.

This is still an issue since there's no way to configure the functions webpack config AFAIK. Could file a ticket for that or rename this one if preferred?
