How to combine schemas in a monolithic monorepo?

[florence-wolfe]

I have a monolithic monorepo with many modules split up by directory. These aren't true separate packages as they're all part of 1 monolith.

I've noticed that if I try to create a root TypeSpec configuration for my entire API in a directory such as /tools/typespec/ and aim to have individual schemas in my modules such as /apps/module_a/schema, /apps/module_b/schema, etc. that I end up with compiler errors.

Here's how I wrote my main.tsp file in my root typespec schema, for example:

import "./api.tsp";
import "../../../app/module_a/schema";

Here's my api.tsp in that same directory:

import "@typespec/http";
import "@typespec/rest";
import "@typespec/openapi3";

using TypeSpec.Http;
using TypeSpec.Rest;

@server("https://myapi.com/api/", "Production API server")
@server("http://localhost:8000/api/", "Local API server")
@service({
    title: "Root API",
})
namespace Root;

Meanwhile, in the module schemas I don't add a tspconfig.yaml, nor package.json as I would expect them to inherit the imports at compile time. Instead, I'm met with errors such as error import-not-found: Couldn't resolve import "@typespec/rest" for each of the files in my modules that are imported by the root.

Is there any way to achieve this for composition purposes? I'd like to avoid requiring everyone to need to write their schemas in the root typespec directory and would prefer to have them scoped to their respective modules.
