Heroku:

• Create a Telegram bot with Telegraf API.
• Create account on Heroku.
• Install Heroku CLI.
• Install and setup git.
• Add micro-bot to the project

  npm install micro-bot --save

• Remove Telegraf dependency from package.json.
• set the start command in package.json:

  ...
  "main": "index.js",
  "scripts": {
  "start": "micro-bot"
  }
  ...

• Make changes in the code.
  • Change the telegraf import to:

    const { Composer } = require('micro-bot')

  • Create bot from Composer:

    const bot = new Composer()

  • Finally remove bot.launch() line instead use:

    module.exports = bot

• Init a new git repo:

  git init

• make .gitignore file with following content:

  node_modules
  

• Login to Heroku:

  heroku login

• Update Heroku config

  heroku config:set --app YourAppId BOT_TOKEN='YOUR BOT TOKEN'
  heroku config:set --app YourAppId BOT_DOMAIN='https://YourAppId.herokuapp.com'

• Create a Procfile in the root of the bot with the following content:

  web: micro-bot -p $PORT
  

• Finally use git to deploy:

  git add .
  git commit -m 'commit message'
  git push heroku master

How to make changes and redeploy the code:
