See [API Documentation](https://zca.tdung.co/) for more details.

## Basic Usages

### Login

```javascript
import { Zalo } from "zca-js";

const zalo = new Zalo();
const api = await zalo.loginQR();
```

### Listen for new messages

```javascript
import { Zalo, ThreadType } from "zca-js";

const zalo = new Zalo();
const api = await zalo.loginQR();

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

    switch (message.type) {
        case ThreadType.User: {
            if (isPlainText) {
                // received plain text direct message
            }
            break;
        }
        case ThreadType.Group: {
            if (isPlainText) {
                // received plain text group message
            }
            break;
        }
    }
});

api.listener.start();
```

**Note**: Only one web listener can run per account at a time. If you open Zalo in the browser while the listener is active, the listener will be automatically stopped.

import { Zalo, ThreadType } from "zca-js";

const zalo = new Zalo();
const api = await zalo.loginQR();

// Echo bot
api.listener.on("message", (message) => {
    const isPlainText = typeof message.data.content === "string";
    if (message.isSelf || !isPlainText) return;

    switch (message.type) {
        case ThreadType.User: {
            api.sendMessage(
                {
                    msg: "echo: " + message.data.content,
                    quote: message, // the message object to reply to (optional)
                },
                message.threadId,

            break;
