workerhelp/subThread.js

基于Node.js worker_threads 的轻量级跨线程RPC通信模块，支持主线程与Worker线程之间的异步方法调用。

const { Worker, parentPort } = require('worker_threads');

class WorkerRPCHandler {
    constructor() {
      this.methods = new Map();
      parentPort.on('message', (data) => 
        data.type === 'request' && this._handleRequest(data));
    }
  
    register(name, fn) {
      if (this.methods.has(name)) {
        throw new Error(`Method ${name} already registered`);
      }
      this.methods.set(name, fn);
    }
  
    async _handleRequest({ id, method, args }) {
      try {
        const fn = this.methods.get(method);
        if (!fn) throw new Error(`Method ${method} not found`);
        const result = await fn(...args);
        parentPort.postMessage({ type: 'response', id, result });
      } catch (error) {
        parentPort.postMessage({ 
          type: 'response', 
          id, 
          error: error.message 
        });
      }
    }
}
  
module.exports = { WorkerRPCHandler };
