Installation

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

Example

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

const bot = new Client({
    name: "something",
    prefix: "!",
    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 } from "@mengkodingan/ckptw";
import { Events } from "@mengkodingan/ckptw/lib/Constant";

const bot = new Client({
    name: "something",
    prefix: "!",
    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 {
    /* as browser name */ 
    name: string;
    /* the bot prefix */
    prefix: Array<string>|string;
    /* 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?: (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!");
      },
  };
  

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";

bot.command('ping', async(ctx) => {
+    const cd = new Cooldown(ctx, 8000);
+    if(cd.onCooldown) return ctx.reply(`slow down... wait ${cd.timeleft}ms`);

    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

• 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: '[phone]' })
        .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/lib/Constant";
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/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.

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 });

Misc

/* replying message */
ctx.reply({ text: "test" });
ctx.reply("you can use string as a first parameter too!");

/* same with bot.command but without prefix */
bot.hears('test', async(ctx) => ctx.reply('test 1 2 3 beep boop...'));

/* will be triggered when someone sends a sticker message */
import { MessageType } from "@mengkodingan/ckptw/lib/Constant";
bot.hears(MessageType.stickerMessage, async(ctx) => ctx.reply('wow, cool sticker'));

ctx.react(jid: string, emoji: string, key?: object);
ctx.react(ctx.id, "👀");

/* get the bot ready at timestamp */
bot.readyAt;

/* get the current jid */
ctx.id // string;

/* get the array of arguments used */
ctx.args // Array<string>;

/* get sender details */
ctx.sender // { jid: string, pushName: string }
