How to develop modules with custom auto-import?

[wuiyang]

I would like to integrate Pothos GraphQL into nitro as a module.

However, I am unsure how to develop a module with build stage (with vfs) to build a single entrypoint (under /graphql). Similar to how nitro build the API/routes folder into a single entrypoint (nitro instance).

So far what I've done:

1. In the module, I append auto import to include /graphql folder.
2. In the module init stage (module function), it will create a virtual file containing all the paths and import function for graphQL server object definition (by looking at the filename postfix).
3. A util script to import and execute all the definition code from this virtual files.
4. A routes/graphql.ts file running the util script to build (and reuse) the graphQL server instance.

However, it cannot import any of the virtual file built by the module, it would have the error:

[plugin node-resolve] Could not resolve import "#nitro-graphql-server" in ../nitro-graphql-server/examples/nitro/server/graphql/queries/get-animals.schema.ts using imports defined in ../nitro-graphql-server/examples/nitro/package.json.

I'm unsure if the process is correct, would greatly appreciate if someone could provide guidance on how to write a module with auto import feature and building an object instance.
