High CPU Usage Issue with whatsapp-web.js

[amoyano]

Is there an existing issue for this?

• [X] I have searched the existing issues

Describe the bug

Whatsapp-web.js is running multiple Puppeteer processes with whatsapp-web.js results in extremely high CPU consumption. The issue is causing excessive resource utilization and negatively impacting the system's performance.

Expected behavior

Puppeteer processes should consume a reasonable amount of CPU resources, ensuring smooth and efficient execution of the application.

Shouldn't be only one processs?

Steps to Reproduce the Bug or Issue

1. Start the application with the provided code.
2. Observe the CPU usage while running multiple Puppeteer processes with whatsapp-web.js.

Relevant Code

I'm running singleton so there is only one instance

import { DataBase } from './database/Database'; import { PuppeteerManager } from './shared/PuppeteerManager'; import { WhatsappClient } from './shared/WhatsappClient'; import logger from './utils/logger';

export class Application { private static instance: Application | null = null; private dataBase = new DataBase(); private whatsappClient = new WhatsappClient(); private puppeteerManager = new PuppeteerManager(); private isInitialized = false;

 private constructor() {
   // Prevents multiple initializations
 }

 public static getInstance(): Application {

   if (Application.instance === null) {
     Application.instance = new Application();
     Application.instance.init(); // Calls initialization only when the instance is created
   }
   return Application.instance;
 }

 private init() {
   if (!this.isInitialized) {
     this.dbConnect(); // Calls dbConnect only once
     this.whatsappClient.initialize(); // Calls whatsappClient.init only once
     this.puppeteerManager.initialize(); // Calls initialize of PuppeteerManager only once
     this.isInitialized = true;
   }
 }

 private dbConnect(): void {
   this.dataBase.initConnect();
 }

 getPuppeteerManager(): PuppeteerManager {
   return this.puppeteerManager;
 }

}

function uncaughtErrorHandler() { process.on('uncaughtException', (error: Error) => { logger.error(Uncaught Exception: ${error.message}); });

 process.on('unhandledRejection', (reason: any) => {
   logger.error(`Unhandled Rejection: ${reason}`);
 });

}

uncaughtErrorHandler();

const appInstance = Application.getInstance();
