Development

CoinBot was built with extensibility in mind. That's why it's based on the following principles and technologies:

Based on Telegraf – A modern framework for Telegram bots.
Commands are modular – They are split into individual files and work inside the chat & inline on the fly.
Website updates automatically – It's built with Next.js and reads the same files the bot is using. If you add command to the bot, it will also be on the website.

Run it locally

After you cloned the repository to your computer, you can run it with npm run dev*.

This command will start the bot itself AND the website on port 3000. It's also possible to start only one of them with either npm run dev:bot or npm run dev:web.

* You have to set the environment variable TOKEN to your Telgram Bot Token in order for it to work. You can obtain it from the BotFather.

Run it in production

Same rules apply as above, but for a production environment I suggest to use npm run build and npm start. :bot and :web can also be applied on those two commands.

Writing a new command

To get started, I would suggest to take a look at the files in the commands/ directory. Every command is described with a function that returns an Object.

Example

export default query => ({
  title: 'Demo',
  trigger: 'demo',
  enabled: true,
  message: `This is a demo. Given query: ${query}`,
  description: `Random item`,
  parameter: 'Example',
  thumb: 'list.png'
})

Options

Key	Type	Required	Description
`title`	`String`	YES	Title/Name of the command.
`trigger`	`String`	YES	The actual command to trigger it. (Without the `/`)
`enabled`	`Boolean`	YES	If `false` the command will be hidden from inline mode and return an error in chat mode. This is useful if your command only works with a certain `query`.
`message`	`String`	YES	The result of the command. This will be returned when it runs.
`description`	`String`	YES	Description for the website, `/start` and inline mode.
`parameter`	`String`	-	Example parameter. Should be in brackets if it's optional. Will be displayed if `enabled` is set to false
`thumb`	`String`	-	Thumbnail for inline mode and website. Image should be placed inside `static/thumbs/`
