问题描述

假设我有2个脚本，father.ts和child.ts，我该如何从father.ts产生child.ts并定期将信息从father.ts发送到child.ts？

Suppose I have 2 script, father.ts and child.ts, how do I spawn child.ts from father.ts and periodically send message from father.ts to child.ts ?

推荐答案

您必须使用 Worker API

father.ts

const worker = new Worker("./child.ts", { type: "module", deno: true });
worker.postMessage({ filename: "./log.txt" });

child.ts

self.onmessage = async (e) => {
  const { filename } = e.data;
  const text = await Deno.readTextFile(filename);
  console.log(text);
  self.close();
};

您可以使用 .postMessage
