## Installation

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

## Example Usage

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

const bot = new Client({
    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();
```

### Using Events

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

const bot = new Client({
    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

```ts
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;
    /* Optional specify a custom Whatsapp Web Version */
    WAVersion?: [number, number, number];
    /* You can mention someone without having to enter each Whatsapp Jid into the `mentions` array. - Default: false */
    autoMention?: boolean;
    /* You can use custom adapters to store your bot's session auth state. The default will be stored locally with baileys default multi auth state. */
    authAdapter?: Promise<any>;
    /* Browser configuration for the WhatsApp Web client. Default to be Chrome in Ubuntu. You should only set a valid/logical browser config, otherwise the pair will fail. */
    browser?: WABrowserDescription;
}
```

## Command Options

Define commands with the following structure:

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

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

```ts
// alternatively 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>;
}

// example
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.

### Main File Setup
  ```ts
  import { CommandHandler } from "@mengkodingan/ckptw";
  import path from "path";

  /* ... */
  const cmd = new CommandHandler(bot, path.resolve() + '/CommandsPath');
  cmd.load();
  //cmd.load(false); // hide log console

  /* ...bot.launch() */
  ```

### Command File Structure

```ts
// command example
module.exports = {
    name: "ping",
    code: async (ctx) => {
        ctx.reply("pong!");
    },
};

// Hears type example
module.exports = {
    name: "hears example",
    type: "hears",
    code: async (ctx) => {
        ctx.reply("Hello world!");
    },
};
```

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

Middleware allows you to intercept and process messages before they reach further processing. Control message flow using `next()` to continue processing or return to terminate. Middleware is only run before executing an existing command. Not all messages go to the middleware.

```ts
bot.use(async (ctx, next) => {
  // Pre-process logic here
  console.log(`received: ${JSON.stringify(ctx.used)}`);

  await next();
});
```

### Key Notes

-  **Execution Order**: Middlewares run sequentially based on registration order.
    ```ts
    bot.use(middleware1); // First run
    bot.use(middleware2); // Second run
    ```
-  **Flow Control**: Omit `next()` to prevent command execution.
    ```ts
    bot.use(async (ctx, next) => {
      if(condition) return; // Block
      await next();
    });
    ```


## Command Cooldown

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

```js
import { Cooldown } from "@mengkodingan/ckptw"; // import the Cooldown class

bot.command('ping', async(ctx) => {
    const cd = new Cooldown(ctx, 8000); // add this. Cooldown time must be in milliseconds.
    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:


```ts
// ⚠ Will always be triggered when the cooldown is over (even though the users only runs the command once)
cd.on("end", () => {
  ctx.reply({ text: "cd timeout" });
})
```

```ts
// Cooldown props

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

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

## Builder

> **⚠ Warning:** Some builders like Button, Sections, or Carousel might not work as expected due to WhatsApp's policies and restrictions. Please ensure your usage complies with WhatsApp's terms of service.

### Button
  Make a button message with Button Builder. 

  ```ts
  export type ButtonType = 'cta_url' | 'cta_call' | 'cta_copy' | 'cta_reminder' | 'cta_cancel_reminder' | 'address_message' | 'send_location' | 'quick_reply';
  ```

  ```ts
  import { ButtonBuilder } from "@mengkodingan/ckptw";

  let button = new ButtonBuilder()
      .setId('!ping')
      .setDisplayText('command Ping')
      .setType('quick_reply')
      .build();

  let button2 = new ButtonBuilder()
      .setId('id2')
      .setDisplayText('copy code')
      .setType('cta_copy')
      .setCopyCode('hello world')
      .build();

  let button3 = new ButtonBuilder()
      .setId('id3')
      .setDisplayText('@mengkodingan/ckptw')
      .setType('cta_url')
      .setURL('https://github.com/mengkodingan/ckptw')
      .setMerchantURL('https://github.com/mengkodingan')
      .build();

  // use sendInteractiveMessage if you dont want to quote the message.
  ctx.replyInteractiveMessage({ 
    body: 'this is body', 
    footer: 'this is footer', 
    nativeFlowMessage: { buttons: [button, button2, button3] } 
  })
  ```

### Sections
  Sections message is like a list.

  ```ts
  import { SectionsBuilder } from "@mengkodingan/ckptw";

  let section1 = new SectionsBuilder()
    .setDisplayText("Click me")
    .addSection({
      title: 'Title 1',
      rows: [
        { header: "Row Header 1", title: "Row Title 1", description: "Row Description 1", id: "Row Id 1" },
        { header: "Row Header 2", title: "Row Title 2", description: "Row Description 2", id: "Row Id 2" }
      ]
    })
    .addSection({
      title: 'This is title 2',
      rows: [
        { title: "Ping", id: "!ping" },
        { title: "Hello world", id: "hello world" },
      ]
    })
    .build();


  ctx.sendInteractiveMessage(ctx.id!, { 
    body: 'this is body', 
    footer: 'this is footer', 
    nativeFlowMessage: { buttons: [section1] }  // pass it to the buttons property
  })
  ```

### Carousel
  A carousel message is a type of message that slides like a carousel.

  ```ts
  import { ButtonBuilder, CarouselBuilder } from "@mengkodingan/ckptw";

  let button = new ButtonBuilder()
      .setId('!ping')
      .setDisplayText('command Ping')
      .setType('quick_reply')
      .build();

  let exampleMediaAttachment = await ctx.prepareWAMessageMedia({ image: { url:  "https://github.com/mengkodingan.png" } }, { upload: ctx._client.waUploadToServer })
  let cards = new CarouselBuilder()
    .addCard({
      body: "BODY 1",
      footer: "FOOTER 1",
      header: {
        title: "HEADER TITLE 1",
        /* card headers must have media attachments */
        hasMediaAttachment: true,
        ...exampleMediaAttachment
      },
      nativeFlowMessage: { buttons: [button] } // needs at least 1 button
    })
    .addCard({
      body: "BODY 2",
      footer: "FOOTER 2",
      header: {
        title: "HEADER TITLE 2",
        /* card headers must have media attachments */
        hasMediaAttachment: true,
        ...exampleMediaAttachment // you can use other media attachments
      },
      nativeFlowMessage: { buttons: [button] } // needs at least 1 button
    })
    .build();


  ctx.replyInteractiveMessage({ 
      body: "this is body",
      footer: "this is footer",
      carouselMessage: {
          cards,
      },
  });
  ```

### Contact
  Send a contact.

  ```ts
  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".

  ```ts
  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

You can configure the collector using the following options:
```ts
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
  ```ts
  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
  ```ts
  ctx.awaitMessages({ time: 10000 }).then((m) => ctx.reply(`got ${m.length} array length`)).catch(() => ctx.reply('end'))
  ```

## Downloading Media

The example below demonstrates saving a received image to `./saved.jpeg`.

```ts
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.msg.media.toBuffer();
        fs.writeFileSync('./saved.jpeg', buffer);
    }
});
```

### Accessing Media Buffers or Streams

```ts
// Get current message media
ctx.msg.media.toBuffer();
ctx.msg.media.toStream();

// Get quoted message media
ctx.quoted.media.toBuffer();
ctx.quoted.media.toStream();
```

## Events

To utilize events, import the `Events` constant:

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

### Available Events
- **ClientReady** - Triggered when the bot is ready.
- **MessagesUpsert** - Fired when a message is received.
- **QR** - QR code is ready to scan.
- **GroupsJoin** - Triggered when the bot joins a group.
- **UserJoin** - Triggered when someone joins a group the bot is in.
- **UserLeave** - Triggered when someone leaves a group.
- **Poll** - Triggered when a poll message is created.
- **PollVote** - Triggered when someone votes in a poll.
- **Reactions** - Triggered when a message receives a reaction.
- **Call** - Triggered when someone calls, or a call is accepted/rejected.
- **ConnectionUpdate** - Triggered when there is a change in the bot's connection status.

## Sending Message

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

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

/* send 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" });

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

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

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

## Formatter
WhatsApp supports formatting in messages, such as bold or italic text. Use the following functions to format strings:

```ts
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);
```

For more details, visit the [WhatsApp FAQ on formatting]((https://faq.whatsapp.com/539178204879377/?cms_platform=web).).

## Editing Message
```ts
let res = await ctx.reply("old text");
ctx.editMessage(res.key, "new text");
```

## Deleting Message
```ts
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.

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

## Mentions

### Get Mentions
Retrieve an array of mentioned users' JIDs. 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.

```ts
ctx.getMentioned() // Returns an array of JIDs
```

### Auto Mention
You can mention someone **without** having to enter each Whatsapp Jid into the `mentions` array.

- First, you need to enable the `autoMention` option in your client.
  ```ts
  const bot = new Client({
    // ...
    autoMention: true // enable this
  });
  ```
- You can directly type `@` followed by the user number to be mentioned. For example like this:
  ```ts
  ctx.reply("Hello @62812345678");
  ```

If you are still confused about what this is, perhaps you can check out the code comparison for mentioning someone below:

```ts
// autoMention: true
ctx.reply("Hello @62812345678");

// autoMention: false, you must manually specify the mentions
ctx.reply({ text: "Hello @62812345678", mentions: ['62812345678@s.whatsapp.net'] });
```

## Custom Auth Adapter

You can use a variety of adapters, but here is an example of using the mysql adapter from [mysql-baileys](https://www.npmjs.com/package/mysql-baileys) library. This is optional, basically the auth session will be stored locally using the built-in `useMultiFileAuthState` adapter from `@whiskeysockets/baileys`.

```ts
// ...
import { useMySQLAuthState } from 'mysql-baileys'; // For more examples of using mysql-baileys, go to npmjs.com/mysql-baileys.

const bot = new Client({
    prefix: "!",
    readIncommingMsg: true,
    // directly assigned to authAdapter.
    authAdapter: useMySQLAuthState({
      session: "session", 
      password: '',
      database: 'baileys',
    })
});

// ...
```
  
## Group Stuff
```ts
ctx.groups.create(subject: string, members: string[]);
ctx.groups.inviteCodeInfo(code: string);
ctx.groups.acceptInvite(code: string);
ctx.groups.acceptInviteV4(key: string | proto.IMessageKeinviteMessage: proto.Message.IGroupInviteMessage);
```
```ts
ctx.group(jid?: string); // jid is optional

ctx.group().members();
ctx.group().inviteCode();
ctx.group().revokeInviteCode();
ctx.group().joinApproval(mode: "on" | "off");
ctx.group().leave();
ctx.group().membersCanAddMemberMode(mode: "on" | "off");
ctx.group().metadata();
ctx.group().getMetadata(key: keyof GroupMetadata);
ctx.group().name();
ctx.group().description();
ctx.group().owner();
ctx.group().isAdmin(jid: string);
ctx.group().isSenderAdmin();
ctx.group().isBotAdmin();
ctx.group().toggleEphemeral(expiration: number);
ctx.group().updateDescription(description: number);
ctx.group().updateSubject(subject: number);
ctx.group().membersUpdate(members: string[], action: ParticipantAction);
ctx.group().kick(members: string[]);
ctx.group().add(members: string[]);
ctx.group().promote(members: string[]);
ctx.group().demote(members: string[]);
ctx.group().pendingMembers();
ctx.group().pendingMembersUpdate(members: string[], action: 'reject' | 'approve');
ctx.group().approvePendingMembers(members: string[]);
ctx.group().rejectPendingMembers(members: string[]);
ctx.group().updateSetting(setting: 'announcement' | 'not_announcement' | 'locked' | 'unlocked')
ctx.group().open()
ctx.group().close()
ctx.group().lock()
ctx.group().unlock()
```
