How did it come about?

After try make may own bot with currents nodejs libraries ( Telegraf and others) and face some issues like:

• Uncaught exception
• Bugs, memory leaks
• About weeks to accept pull request with bugfix
• Very verbose to work listening to answers and creating buttons / menus

That module arose from my need to create a bot, so I needed to quickly develop a module that would meet my needs, so I didn't bother to implement all the methods / features available in the telegram API.

My only concern was to develop code that didn't break the application.

If you want to help implement new features or improve code quality, your help is most welcome! 😊

Requirements

• Nodejs V8 +

Limitations

It's only for long polling bot, Webhook will be implemented soon. Feel free to help us!

Install

$ npm install telegram-bot-maker

Usage

const { Bot } = require('telegram-bot-maker')

const bot = new Bot({
    token: 'YOUR-BOT-TOKEN',  
    updateInterval: 500, // interval that bot will looking for updates
  })

bot.lauch()

Bot Methods

Start the bot

  bot.lauch()

Stop the bot

  bot.stop()

Add listener to command

  // * Is Required
  //<String> command *
  //<Function> handler *
  bot.command(command, handler)

  //exemple
  bot.command('/menu', (ctx, update) => {
    ctx.reply('There is a reply to menu command')
  })

Add listener to bot

  // * Is Required
  //<String> listener * 'message' || 'update'
  //<Function> handler *
  bot.on(listener, handler)

  //exemple
  bot.on('message', (ctx, update) => {
    ctx.reply('A reply to your msg')
  })

Wait For User reply

ctx.waitForReply(handler)

bot.on('message', (ctx, update) => {

  ctx
    .reply('Whats is your first name?')
    .waitForReply((userReply)=>{
      const { message } = userReply
      ctx.setState({ firstName: message.text })
      ctx.reply(`nice ${message.text}, so whats is your last name?`)
    })
    .waitForReply((userReply)=>{
      const { message } = userReply
      const { firstName } = ctx.getState()
      ctx.reply(`your full name is ${firstName} ${message.text}`)
    })
})

Creating Menu

ctx.replyWithMenu(MenuSettings)

bot.on('message', (ctx, update) => {
  ctx.replyWithMenu({
    text: 'Menu Level 0',   //<String> text                       ( Text of message )
    grid: '2x1',            //<String> grid *Required 'ColsxRow'  ( Grid of the Menu )
    id: 'id-menu-0',        //<String> id *Required               (Id of menu, without it backButton wont work)
    options: [
      {
        label: 'Button 1',  //<String> label *Required           (Label of button)
        id: 'btn-1',        //<String> id *Required              (Id of button)
        params: { 'foo': 'bar' },//<Object> params              (Your custom params if you need)
        onSelect: params => {
          console.log('Button 1 click', params)
          //Output: Button 1 click { 'foo': 'bar' }

        },                //<Function> onSelect *Required       (Called when user press the button)
      },
      {
        label: 'Button 2',
        id: 'btn-2',
        onSelect: params => {
          console.log('Button 2 click')
        },
      },
    ],
  })

})

Submenu

bot.on('message', (ctx, update) => {
  ctx.replyWithMenu({
    text: 'Menu Level 0',
    grid: '2x1',
    id: 'id-menu-0',
    options: [
      {
        label: 'Button 1',
        id: 'btn-1',
        params: { 'my-custom-params': 'my-custom-value' },
        onSelect: params => {
          console.log('Button 1 click', params)
        },
      },
      {
        label: 'Button 2',
        id: 'btn-2',
        onSelect: params => {
          console.log('Button 2 click')
        },
        submenu: {
          text: 'Menu Level 1',
          grid: '1x1',
          id: 'id-menu-1',
          backButton: {
            label: 'Back to level zero menu',
            id: 'id-menu-0',
          }, // Add at the bottom of grid a back button
          options: [
            {
              label: 'Button 3',
              id: 'btn-3',
              onSelect: params => {
                console.log('Button 3 click')
              },
            },
            {
              label: 'Button 4',
              id: 'btn-4',
              onSelect: params => {
                console.log('Button 4 click')
              },
            },
          ]
        }
      },
    ],
  })
})

Custom Inline Buttons

bot.on('message', (ctx, update) => {
  ctx.reply(
    'Testing custom BTNS',
    ctx.keyboard('inline', [
      [
        ctx.buttons.CallBack('Button 1', 'id-btn-1', { params: 'to-btn-1' }, params => {
          console.log('User hit button 1', params)
        })
    ],
      [
        ctx.buttons.CallBack('Button 2', 'id-btn-2', { params: 'to-btn-2' }, params => {
          console.log('User hit button 2', params)
        })
      ],
    ])
  )
})

Custom Buttons

bot.on('message', (ctx, update) => {
  ctx.reply(
    'Testing custom BTNS',
    ctx.keyboard(null, [ //Just the inline params changed
      [
        ctx.buttons.CallBack('Button 1', 'id-btn-1', { params: 'to-btn-1' }, params => {
          console.log('User hit button 1', params)
        })
    ],
      [
        ctx.buttons.CallBack('Button 2', 'id-btn-2', { params: 'to-btn-2' }, params => {
          console.log('User hit button 2', params)
        })
      ],
    ])
  )
})

send Photos to user

To send photos to user you must pass url or filePath param.

ctx
  .reply('Want a photo?')
  .waitForReply(() => {
    ctx.replyWithImage({
      file: {
        type: 'photo', // Is required
        //url: 'https://images.freeimages.com/images/large-previews/b31/butterfly-1392408.jpg',
        filePath: './docs/menu-exemple-1.png',
      },
    })
  })

Notes

All updates that remain when the bot is off will be bypassed, it will only react to updates that happen while it is alive, I choose for this architecture to prevent anomalous behavior.

This module is in its infancy and still relies on possible help to make it more robust.
