Establish a channel between the main thread and the worker, can send information using promise-based methods, the promise gets resolved when the recipient responds.

problem
Generally use postMessage
to send messages,
and use onmessage
to get messages,
but they have no corresponding relationship,
you are not sure whether the obtained message is what you need.
worker.postMessage('1 + 1'); // When do you get results?
window.onmessage = ({ data }) => {
// `data` is it a `1 + 1` result ?
}
resolve
Add a unique id when sending a message, Check id when getting message, execute callback.
This library works like this.
install
npm i @mantou/channel
usage
main thread:
const channel = new Channel(woker);
channel
.sendMessage('ping')
// Received reply
.then(data => console.log('Received worker thread message:', data))
.catch(console.error);
worker thread:
const channel = new Channel(self);
channel.onMessage.addListener(data => {
console.log('Received main thread message:', data);
// Reply sender
return 'pong';
});
