Reference .d.ts files from within .js files?

[FredKSchott]

Hey all,

I'm looking to add bundled type definitions to the Pika CDN, so that any npm package that comes with types would have a single bundled .d.ts file available to complement it. From reading the deno manual, I understand that it will then be possible to do this:

// @deno-types="https://cdn.pika.dev/lodash-es/latest?types"
import * as foo from "https://cdn.pika.dev/lodash-es/latest";

Pika CDN bundles each package that it serves into a single ESM JS file that can be imported by Deno & Browsers. Since I have control over that file at build time, is there anything special I can do/add to have the https://cdn.pika.dev/lodash-es/latest file itself tell deno where it's type definition lives? That way, you could get rid of the user-provided // @deno-types= comment when using Pika CDN.
