importw

Permission restricted imports for Deno.

import {
  importw,
  workerSymbol,
} from "https://x.nest.land/importw@0.4.0/mod.ts";

// Import module from within a worker
const { log, add, [workerSymbol]: worker } = await importw(
  "https://x.nest.land/importw@0.4.0/examples/basic/exampleMod.ts",
  {
    name: "exampleWorker",
    deno: false,
  },
);

// Run code within worker
await log(`add(40, 2) in a worker:`, await add(40, 2));

(worker as Worker).terminate();

About

This module is a PoC for demonstrating how one could import modules from within a Deno Worker and expose the methods to the main runtime.

This allows for isolation around the imported module, and allows consumers to restrict an imported module’s access to the Deno namespace and / or privileged operations.

This module consists of ports / adaptions of Comlink and import-from-worker as well as a few other libraries to create the bridge between main runtime and Worker. Due to limited support for Workers in Deno, some features of Comlink etc. are not available as they require structured cloning, transfer objects and the MessageChannel API, which have not yet landed in Deno yet. Simple functional examples work well however.
