liqueur

liqueur

A rich-featured and flexible command framework to develop WhatsApp bot with Baileys inspired by @sapphire framework.

Installation

npm i liqueur

Usage

The usage is similar to @sapphire/framework, you can open our coming soon example bot to get started.

Listening to Baileys' socket

Because Baileys' event emitter is kinda different (not a pure EventEmitter), you can use the following options to listen to it:

@ApplyOptions<ListenerOptions>({
    event: "connection.update", // Change the event name
    emitter: "baileysEmitter" // Specify the emitter (must be "baileysEmitter" !!)
})

While doing so will make the listener listens to the Baileys' event emitter. If you didn't specify the emitter name, it will listens to FrameworkClient internal events as defined here

Handle credentials nor connection update

We didn't handle the creds.update nor connection.update event by default. To make the bot working, please handle it according to your respective auth's state handler.

For example, using useMultiFileAuthState:

import { container } from "@sapphire/pieces";

@ApplyOptions<ListenerOptions>({
    event: "creds.update",
    emitter: "baileysEmitter"
})
export class CredsUpdate extends Listener {
    public async run(): Promise<any> {
        await container.authState?.saveCreds();
        this.container.client.logger.info("Credentials has been updated.");
    }
}

...in your main file:

import { container } from "@sapphire/pieces";
import { useMultiFileAuthState, makeWASocket } from "@whiskeysockets/baileys";

const loggerOptions = createLogger({
    name: "WhatsApp-bot",
    debug: mode === "dev"
});

const client = new FrameworkClient({
    baseUserDirectory: "dist",
    fetchPrefix: () => Promise.resolve(prefix),
    makeWASocket: () => {
        container.authState = useMultiFileAuthState("auth_state");
        return makeWASocket({
            auth: {
                // Pass the auth strategy here
                creds: container.authState.state.creds,
                // @ts-expect-error-next-line
                keys: makeCacheableSignalKeyStore(container.authState.state.keys, logger)
            },
            printQRInTerminal: true
        })
    },
    logger
});

Don't forget to handle the reconnection:

import { Listener, ListenerOptions } from "liqueur";
import { BaileysEventMap, DisconnectReason, useMultiFileAuthState } from "@whiskeysockets/baileys";
import { Boom } from "@hapi/boom";
import { cast } from "@sapphire/utilities";
import { ApplyOptions } from "@nezuchan/decorators";

@ApplyOptions<ListenerOptions>({
    event: "connection.update",
    emitter: "baileysEmitter"
})
export class ConnectionUpdate extends Listener {
    public async run({ lastDisconnect, connection }: BaileysEventMap["connection.update"]): Promise<any> {
        const shouldReconnect = cast<Boom | undefined>(lastDisconnect)?.output?.statusCode !== DisconnectReason.loggedOut;
        if (connection === "close") {
            this.container.client.logger.warn(
                `Connection closed due to ${lastDisconnect?.error?.message ?? "unknown reason"
                }, reconnecting ${shouldReconnect}`
            );
            if (shouldReconnect) {
                await this.container.client.login();
            }
        } else if (connection === "open") {
            this.container.client.logger.info("Opened connection.");
        }
    }
}
