HOANGVIET

This is an unofficial Zalo API for personal account. It work by simulating the browser to interact with Zalo Web. We developed this library based on zca-js library so don't ask why they are the same

disclaimer: We are not responsible if your account is locked or banned by Zalo. Use it at your own risk.

Basic Usages

Login

import { Zalo } from "HOANGVIET";

const zalo = new Zalo(
    {
        cookie: "your_cookie_here",
        imei: "your_imei_here",
        userAgent: "your_user_agent_here",
    },
    {
        selfListen: false,
        checkUpdate: true,
    },
);

const api = await zalo.login();

Alternative: We also support J2TEAM Cookies extension:

import { Zalo } from "HOANGVIET";

const zalo = new Zalo(
    {
        cookie: JSON.parse(fs.readFileSync("./cookies.json", "utf-8")),
        imei: "your_imei_here",
        userAgent: "your_user_agent_here",
    },
    {
        selfListen: false,
        checkUpdate: true,
    },
);

const api = await zalo.login();

• cookie: Your Zalo cookie. You can get it by using J2TEAM Cookies extension or by using browser developer tools.
• imei: Your IMEI created by Zalo. You can get it using browser developer tools: localStorage.getItem('z_uuid') or localStorage.getItem('sh_z_uuid').
• userAgent: Your browser user agent. Better be from the same browser you get cookie.
• selfListen: Listen for messages sent by yourself. Default is false.
• checkUpdate: Check for HOANGVIET update. Default is true.

Listen for new messages

import { Zalo, MessageType } from "HOANGVIET";

const zalo = new Zalo(credentials);
const api = await zalo.login();

api.listener.on("message", (message) => {
    const isPlainText = typeof message.data.content === "string";

    switch (message.type) {
        case MessageType.DirectMessage: {
            if (isPlainText) {
                await ......;
            }
            break;
        }
        case MessageType.GroupMessage: {
            if (isPlainText) {
                await ......;
            }
            break;
        }
    }
});

api.listener.start();

Note: Only one web listener can be started at a time. If you open Zalo in the browser while the listener is running, the listener will be stopped.
