deno land deno doc Test

Deno module to translate Worker’s system of messages into Reader and Writer.

Note that WorkerReader and WorkerWriter access Deno namespace thus Using Deno in worker must be enabled.

Example

Server

import {
  WorkerReader,
  WorkerWriter,
} from "https://deno.land/x/workerio/mod.ts";

const decoder = new TextDecoder();
const encoder = new TextEncoder();

const worker = new Worker(new URL("./worker.ts", import.meta.url).href, {
  type: "module",
  // NOTE:
  // WorkerReader/WorkerWriter need to access 'Deno' namespace.
  deno: {
    namespace: true,
  },
});

const reader = new WorkerReader(worker);
const writer = new WorkerWriter(worker);

await writer.write(encoder.encode("Hello"));
await writer.write(encoder.encode("World"));

for await (const data of Deno.iter(reader)) {
  const text = decoder.decode(data);
  console.log(text);
}

Worker

import {
  WorkerReader,
  WorkerWriter,
} from "https://deno.land/x/workerio/mod.ts";

const decoder = new TextDecoder();
const encoder = new TextEncoder();

async function main(): Promise<void> {
  // deno-lint-ignore no-explicit-any
  const worker = self as any;
  const reader = new WorkerReader(worker);
  const writer = new WorkerWriter(worker);

  for await (const data of Deno.iter(reader)) {
    const text = decoder.decode(data);
    await writer.write(encoder.encode(`!!! ${text} !!!`));
  }
}

main().catch((e) => console.error(e));
