Advanced tools
Web Worker Boss is a lightweight library that provides a simple and intuitive socket-like API for sending and receiving messages between the main thread and the worker.
You can install Web Worker Boss using npm or yarn:
npm install web-worker-boss
or
yarn add web-worker-boss
To use Web Worker Boss for bi-directional communication, follow these steps:
import Boss from 'web-worker-boss';
const boss = new Boss(worker);
boss.on('eventName', (payload) => {
// Handle the received event and payload from the web worker
});
boss.emit('eventName', payload);
import Boss from 'web-worker-boss';
const boss = new Boss(self);
boss.on('eventName', (payload) => {
// Handle the received event and payload from the main thread
});
boss.emit('eventName', payload);
Here's an example demonstrating the usage of Web Worker Boss for bi-directional communication:
import Boss from 'web-worker-boss';
const worker = new Worker('worker.js');
const boss = new Boss(worker);
boss.on('answer', (payload) => {
console.log('Received answer from web worker:', payload.data.answer);
});
boss.emit('ask', { question: 'How are you?' });
import Boss from 'web-worker-boss';
const boss = new Boss(self);
boss.emit('connection', { message: 'Hello, boss!' });
boss.on('ask', (payload) => {
if (payload.data.question === 'How are you?') {
boss.emit('answer', { answer: 'I am fine!' });
} else {
boss.emit('answer', { answer: 'I don\'t understand' });
}
});
In this example, the main script creates a web worker using the Worker constructor and creates an instance of Boss with the worker. It registers an event listener for the 'answer' event and emits an 'ask' event with a question payload.
The web worker script creates an instance of Boss with self, which represents the web worker itself. It emits a 'connection' event to indicate the worker's connection, and it registers an event listener for the 'ask' event. Based on the received question, it emits an 'answer' event with an appropriate answer payload.
Both the main script and the web worker script can communicate with each other using the emit and on methods of the Boss instance.
new Boss(worker: Worker)
Creates a new instance of Boss
with the specified web worker object.
worker
: The web worker object to communicate with.boss.on(event: string, callback: (payload: any) => void)
Registers an event listener for the specified event.
event
: The name of the event to listen for.callback
: The callback function to execute when the event is received. It will receive the payload as a parameter.boss.emit(event: string, payload: MessageEvent)
Emits an event to the web worker.
event
: The name of the event to emit.
payload
: The payload to send along with the event.
That's it! You now have a better understanding of how to use the Web Worker Boss library for bi-directional communication between the main thread and a web worker in your web applications. Feel free to explore more features and advanced usage in the library's documentation or by examining the source code.
