The response from the Whatsapp-web-js API can be delayed

As I work on creating an API to retrieve groupChat IDs using the express framework and whatsapp-web-js library, I've encountered an issue. The initial request to the endpoint after starting the server yields a response within 31 seconds, but subsequent responses seem to get stuck in a strange "loop" (although I'm not certain if that's the correct term to describe it).

Here are the steps I've taken so far:

const express = require("express");

const app = express();
app.listen(3000, () => {
    console.log("Server running on port 3000");
});

const qrcode = require('qrcode-terminal');
const { Client, LocalAuth } = require('whatsapp-web.js');
const client = new Client({ authStrategy: new LocalAuth() });

app.get("/", (req, res, next) => {
    client.on('ready', async () => {
        res.json(['test response']);
    });
});

I have a feeling that I may be making a mistake somewhere, but I can't pinpoint exactly what it is.

Answer №1

After making a few adjustments to my code, the issue was resolved successfully. Here is the updated version of my code snippet:

const express = require("express");
const qrcode = require('qrcode-terminal');
const { Client, LocalAuth } = require('whatsapp-web.js');

const client = new Client({ authStrategy: new LocalAuth() });
const app = express();
client.initialize();

app.listen(3000, () => {
    console.log("Server is now running on port 3000");
});
client.on('ready', () => {
    res.json(['test response'])
});

app.get("/", async (req, res, next) => {
    const chats = await client.getChats();
    res.json([chats]);
});
