在React中创建一个Web Worker

我有一个用create-react-app创建的React应用,没有弹出。我正在尝试使用网络工作者。我已经尝试过worker-

loader软件包(https://github.com/webpack-contrib/worker-

loader)。

如果我尝试开箱即用(- import Worker from 'worker-

loader!../workers/myworker.js';)的worker-loader ,我将收到一条错误消息,告诉我Create React

App不支持Webpack加载器,我已经知道。

解决方案是弹出应用程序(我不希望这样做)并编辑webpack.config.js还是在React应用程序中使用Web Worker的其他方法?

正如我在上面的问题的编辑中所写的那样,我在这里找到了解决方案:https : //github.com/facebookincubator/create-react-

这是一个工作示例:

// worker.js

const workercode = () => {

self.onmessage = function(e) {

console.log('Message received from main script');

var workerResult = 'Received from main: ' + (e.data);

console.log('Posting message back to main script');

self.postMessage(workerResult);

}

};

let code = workercode.toString();

code = code.substring(code.indexOf("{")+1, code.lastIndexOf("}"));

const blob = new Blob([code], {type: "application/javascript"});

const worker_script = URL.createObjectURL(blob);

module.exports = worker_script;

然后,在需要使用Web Worker的文件中:

import worker_script from './worker';

var myWorker = new Worker(worker_script);

myWorker.onmessage = (m) => {

console.log("msg from worker: ", m.data);

};

myWorker.postMessage('im from main');
