Installation

npm install whasapi
# or
yarn add whasapi
# or
pnpm add whasapi

Example

import { Client } from "whasapi";
import { Events, MessageType } from "whasapi/lib/Constant";

const bot = new Client({
    name: "something",
    prefix: "!",
    printQRInTerminal: true,
    readIncommingMsg: true
});

bot.ev.once(Events.ClientReady, (m) => {
    console.log(`ready at ${m.user.id}`);
});

bot.command('ping', async(sock) => sock.reply({ text: 'pong!' }));
bot.command('hi', async(sock) => sock.reply('hello! you can use string as a first parameter in reply function too!'));

bot.hears('test', async(sock) => sock.reply('test 1 2 3 beep boop...'));
bot.hears(MessageType.stickerMessage, async(sock) => sock.reply('wow, cool sticker'));
bot.hears(['help', 'menu'], async(sock) => sock.reply('hears can be use with array too!'));
bot.hears(/(using\s?)?regex/, async(sock) => sock.reply('or using regex!'));

bot.launch();

Or using the Events

import { Client } from "whasapi";
import { Events } from "whasapi/lib/Constant";

const bot = new Client({
    name: "something",
    prefix: "!", // you can also use array or regex too,
    printQRInTerminal: true,
    readIncommingMsg: true
});

bot.ev.once(Events.ClientReady, (m) => {
    console.log(`ready at ${m.user.id}`);
});

bot.ev.on(Events.MessagesUpsert, (m, sock) => {
    if(m.key.fromMe) return;
    if(m.content === "hello") {
        sock.reply("hi 👋");
    }
})

bot.launch();

Client Configuration

export interface ClientOptions {
    /* as browser name */ 
    name: string;
    /* the bot prefix */
    prefix: Array<string> | string | RegExp;
    /* should bot mark as read the incomming messages? */
    readIncommingMsg?: boolean;
    /* path to the auth/creds directory */
    authDir?: string;
    /* print the qr in terminal? */
    printQRInTerminal?: boolean;
    /* time taken to generate new qr in ms (default is 60000 ms or 1 minute) */
    qrTimeout?: number;
    /* should the client mark as online on connect? default to be true. */
    markOnlineOnConnect?: boolean;
}

Command Options

bot.command(opts: CommandOptions | string, code?: (sock: sock) => Promise<any>)

// you can use the new command function code too! 
bot.command('ping', async(sock) => sock.reply('pong!'))

// or you can use the old one!
export interface CommandOptions {
    /* command name */
    name: string;
    /* command aliases */
    aliases?: Array<string>;
    /* command code */
    code: (sock: sock) => Promise<any>;
}

// e.g
bot.command({
  name: 'ping',
  code: async(sock) => sock.reply('pong!');
})

Command Handler

With command handler you dont need all your command is located in one file.

• in your main file

  import { CommandHandler } from "whasapi";
  import path from "path";
  
  /* ... */
  const cmd = new CommandHandler(bot, path.resolve() + '/CommandsPath');
  cmd.load();
  
  /* ...bot.launch() */

• in your command file

  module.exports = {
      name: "ping",
      code: async (sock) => {
        sock.reply("pong!");
      },
  };

  You can add a type property to define the handler type... For now there are only command and hears types.

  module.exports = {
      name: "hears with command handler",
      type: "hears", // add this
      code: async (sock) => {
        sock.reply("hello world!");
      },
  };

Command Cooldown

Cooldown can give a delay on the command. This can be done to prevent users from spamming your bot commands.

import { Cooldown } from "whasapi"; // import Cooldown class

bot.command('ping', async(sock) => {
    const cd = new Cooldown(sock, 8000); // add this
    if(cd.onCooldown) return sock.reply(`slow down... wait ${cd.timeleft}ms`); // if user has cooldown stop the code by return something.

    sock.reply('pong!')
})

if you want to trigger some function when the cooldown end, you can use the "end" events in the cooldown:

⚠ Will always be triggered when the cooldown is over (even though he only runs the command once)

cd.on("end", () => {
  sock.reply({ text: "cd timeout" });
})

Cooldown getter:

/* check if sender is on cooldown */
cd.onCooldown; // boolean

/* check the cooldown time left (in ms) */
cd.timeleft; // number

Builder

⚠ The button and section are now deprecated!

• Button

  make a button message with Button Builder.

  import { ButtonBuilder } from "whasapi";
  
  // you can use more than 1 builder
  const btn = new ButtonBuilder()
      .setId("id1") // button id
      .setDisplayText("button 1") // button text
      .setType(1); // type
  
  // pass it into buttons array
  sock.sendMessage(sock.id, { text: "buttons", buttons: [btn] });

• Sections

  Sections message is like a list.

  import { SectionBuilder } from "whasapi";
  
  // you can use more than 1 like buttons
  const a = new SectionBuilder()
      .setTitle("title") // sections title
      .setRows(
        { title: "abc", rowId: 1 },
        { title: "b", rowId: 2, description: "a" }
      ); // make a rows
  
  sock.sendMessage(sock.id, {
    text: "sections",
    buttonText: "button text", // buttonText is for the display text for the button
    sections: [a], // pass it into sections array
  });

• Contact

  send a contact.

  import { VCardBuilder } from "whasapi";
  
  const vcard = new VCardBuilder()
      .setFullName("John Doe") // full name
      .setOrg("PT Mencari Cinta Sejati") // organization name
      .setNumber("62xxxxx") // phone number
      .build(); // required build function at end
  
  sock.reply({ contacts: { displayName: "John D", contacts: [{ vcard }] }});

• Template Buttons

  send a button with "attachment".

  import { TemplateButtonsBuilder } from "whasapi";
  
  const templateButtons = new TemplateButtonsBuilder()
        .addURL({ displayText: 'whasapi at Github', url: 'https://github.com/KazeDevID/whasapi' })
        .addCall({ displayText: 'call me', phoneNumber: '+62xxxxxx' })
        .addQuickReply({ displayText: 'just a normal button', id: 'btn1' })
        .build(); // required build function at end
  
    sock.sendMessage(sock.id, { text: "template buttons", templateButtons });

Collector

There are several options that can be used in the collector:

export interface CollectorArgs {
    /* collector timeout in milliseconds */
    time?: number;
    /* how many messages have passed through the filter */
    max?: number;
    /* will be stop if end reason is match with your col.stop reason  */
    endReason?: string[];
    /* limit how many messages must be processed. */
    maxProcessed?: number;
    /* a function as a filter for incoming messages. */
    filter?: () => boolean;
}

• Message Collector

  let col = sock.MessageCollector({ time: 10000 }); // in milliseconds
  sock.reply({ text: "say something... Timeout: 10s" });
  
  col.on("collect", (m) => {
      console.log("COLLECTED", m); // m is an Collections
      sock.sendMessage(sock.id, {
          text: `Collected: ${m.content}\nFrom: ${m.sender}`,
      });
  });
  
  col.on("end", (collector, r) => {
      console.log("ended", r); // r = reason
      sock.sendMessage(sock.id, { text: `Collector ended` });
  });

• Awaited Messages

  sock.awaitMessages({ time: 10000 }).then((m) => sock.reply(`got ${m.length} array length`)).catch(() => sock.reply('end'))

Downloading Media

the code below will save the received image to ./saved.jpeg

import { MessageType } from "whasapi/lib/Constant";
import fs from "node:fs";

bot.ev.on(Events.MessagesUpsert, async(m, sock) => {
    if(sock.getMessageType() === MessageType.imageMessage) {
        const buffer = await sock.getMediaMessage(sock.msg, 'buffer')
        fs.writeFileSync('./saved.jpeg', buffer);
    }
})

Events

Firstly you must import the Events Constant like this:

import { Events } from "whasapi/lib/Constant";

• Available Events

  • ClientReady - Emitted when the bot client is ready.
  • MessagesUpsert - Received an messages.
  • QR - The bot QR is ready to scan. Return the QR Codes.
  • GroupsJoin - Emitted when bot joining groups.
  • UserJoin - Emitted when someone joins a group where bots are also in that group.
  • UserLeave - Same with UserJoin but this is when the user leaves the group.
  • Poll - Emitted when someone create a poll message.
  • PollVote - Emitted when someone votes for one/more options in a poll.
  • Reactions - Emitted when someone reacts to a message.

Sending Message

/* sending a message */
sock.sendMessage(sock.id, { text: "hello" });

/* quote the message */
sock.reply("hello");
sock.reply({ text: "hello" });

/* sending an image */
sock.sendMessage(sock.id, { image: { url: 'https://example.com/image.jpeg' }, caption: "image caption" });
sock.reply({ image: { url: 'https://example.com/image.jpeg' }, caption: "image caption" });

/* sending an audio */
sock.reply({ audio: { url: './audio.mp3' }, mimetype: 'audio/mp4', ptt: false }); // if "ptt" is true, the audio will be send as voicenote

/* sending an sticker */
sock.reply({ sticker: { url: './tmp/generatedsticker.webp' }});

/* sending an video */
import fs from "node:fs";
sock.reply({ video: fs.readFileSync("./video.mp4"), caption: "video caption", gifPlayback: false });

Formatter

WhatsApp allows you to format text inside your messages. Like bolding your message, etc. This function formats strings into several markdown styles supported by WhatsApp.

⚠ Inline code and quote are only supported in IOS and Whatsapp Web. If your user is on another platform it might look different.

You can see the Whatsapp FAQ about formatting messages here.

import { bold, inlineCode, italic, monospace, quote, strikethrough } from "whasapi";

const str = "Hello World";

const boldString = bold(str);
const italicString = italic(str);
const strikethroughString = strikethrough(str);
const quoteString = quote(str);
const inlineCodeString = inlineCode(str);
const monospaceString = monospace(str);

Editing Message

let res = await sock.reply("old text");
sock.editMessage(res.key, "new text");

Deleting Message

let res = await sock.reply("testing");
sock.deleteMessage(res.key);

Poll Message

singleSelect means you can only select one of the multiple options in the poll. Default to be false

sock.sendPoll(sock.id, { name: "ini polling", values: ["abc", "def"], singleSelect: true })

Get Mentions

You can use the function from sock to get the jid array mentioned in the message. For example, a message containing hello @jstn @person where @jstn & @person is a mention, then you can get an array containing the jid of the two mentioned users.

sock.getMentioned() // return array
