Installation

npm install @mengkodingan/ckptw
# or
yarn add @mengkodingan/ckptw
# or
pnpm add @mengkodingan/ckptw

Example

import { Client, Events, MessageType } from "@mengkodingan/ckptw";

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

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

bot.launch();

Or using the Events

import { Client, Events } from "@mengkodingan/ckptw";

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, ctx) => {
    if(m.key.fromMe) return;
    if(m.content === "hello") {
        ctx.reply("hi 👋");
    }
})

bot.launch();

Client Configuration

export interface ClientOptions {
    /* The bot prefix */
    prefix: Array<string> | string | RegExp;
    /* Should bot mark as read the incomming messages? - Default: false */
    readIncommingMsg?: boolean;
    /* Path to the auth/creds directory - Default: ./state */
    authDir?: string;
    /* Print the qr in terminal? - Default: false */
    printQRInTerminal?: boolean;
    /* Time taken to generate new qr in ms - Default: 60000 ms (1 minute) */
    qrTimeout?: number;
    /* Should the client mark as online on connect? - Default: true */
    markOnlineOnConnect?: boolean;
    /* The bot phone number starts with country code (e.g 62xxx), Used for pairing code purposes. */
    phoneNumber?: string;
    /* Connect the bot using pairing code method instead of qr method. - Default: false */
    usePairingCode?: boolean;
    /* Should a bot reply when the bot number itself uses its bot command? - Default: false */
    selfReply?: boolean;
}

Command Options

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

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

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

// e.g
bot.command({
  name: 'ping',
  code: async(ctx) => ctx.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 "@mengkodingan/ckptw";
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 (ctx) => {
      ctx.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 (ctx) => {
      ctx.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 "@mengkodingan/ckptw"; // import Cooldown class

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

    ctx.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", () => {
  ctx.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 "@mengkodingan/ckptw";

// 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
ctx.sendMessage(ctx.id, { text: "buttons", buttons: [btn] });

Sections

Sections message is like a list.

import { SectionBuilder } from "@mengkodingan/ckptw";

// 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

ctx.sendMessage(ctx.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 "@mengkodingan/ckptw";

const vcard = new VCardBuilder()
    .setFullName("John Doe") // full name
    .setOrg("PT Mencari Cinta Sejati") // organization name
    .setNumber("621234567890") // phone number
    .build(); // required build function at end

ctx.reply({ contacts: { displayName: "John D", contacts: [{ vcard }] }});

Template Buttons

send a button with "attachment".

import { TemplateButtonsBuilder } from "@mengkodingan/ckptw";

const templateButtons = new TemplateButtonsBuilder()
      .addURL({ displayText: 'ckptw at Github', url: 'https://github.com/mengkodingan/ckptw' })
      .addCall({ displayText: 'call me', phoneNumber: '+1234567890' })
      .addQuickReply({ displayText: 'just a normal button', id: 'btn1' })
      .build(); // required build function at end

  ctx.sendMessage(ctx.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 = ctx.MessageCollector({ time: 10000 }); // in milliseconds
ctx.reply({ text: "say something... Timeout: 10s" });

col.on("collect", (m) => {
    console.log("COLLECTED", m); // m is an Collections
    ctx.sendMessage(ctx.id, {
        text: `Collected: ${m.content}\nFrom: ${m.sender}`,
    });
});

col.on("end", (collector, r) => {
    console.log("ended", r); // r = reason
    ctx.sendMessage(ctx.id, { text: `Collector ended` });
});

Awaited Messages

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

Downloading Media

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

import { MessageType } from "@mengkodingan/ckptw";
import fs from "node:fs";

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

Events

Firstly you must import the Events Constant like this:

import { Events } from "@mengkodingan/ckptw";

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 */
ctx.sendMessage(ctx.id, { text: "hello" });

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

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

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

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

/* sending an video */
import fs from "node:fs";
ctx.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.

⚠ Some new text formatting is only available on Web and Mac desktop.

You can see the Whatsapp FAQ about formatting messages here.

import { bold, inlineCode, italic, monospace, quote, strikethrough } from "@mengkodingan/ckptw";

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 ctx.reply("old text");
ctx.editMessage(res.key, "new text");

Deleting Message

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

Poll Message

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

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

Get Mentions

You can use the function from ctx 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.

ctx.getMentioned() // return array
