Deno Monorepo with nested applications and packages

I'm trying to move a node monorepo from NPM to Deno. It's got a set of applications in a directory called services, and set of libraries used by said services in packages. These are all independent, and are registered to the apps workspace (@example) for now. eg: if a service myapp registered as @example/myapp wanted packages/utils, it'd import @example/utils and it'd find it within packages. I'm trying to do the same in NPM but it seems like everything has to be flat, at the root. Am I not able to register workspaces that are deeper than the root directory? I've got /packages/foo/deno.json and packages/foo/mod.ts with a funciton exported. the deno.js has the following contents:

{
  "name": "@example/foo",
  "exports": "./mod.ts",
  "version": "1.0.0"
}

{
  "name": "@example/foo",
  "exports": "./mod.ts",
  "version": "1.0.0"
}

The root project has this deno.json:

{
  "workspace": [
    "./services/api",
    "./packages/foo"
  ]
}

{
  "workspace": [
    "./services/api",
    "./packages/foo"
  ]
}

I'm unable to import @example/foo in API, as it says ..

error: Relative import path "@example/foo" not prefixed with / or ./ or ../ and not in import map from "file:///app/mod.ts"

error: Relative import path "@example/foo" not prefixed with / or ./ or ../ and not in import map from "file:///app/mod.ts"

The goal is to run these in docker containers in skaffold.

You can use glob expressions for workspace like ./services/*

Regarding this: Have you added @example/foo to the imports section of the consuming package's deno.json?

Right, nested workspaces are not supported in Deno. Relevant issue https://github.com/denoland/deno/issues/26879
