2Space - Telegram Bot in 30 Lines of Code Example

You can try it out on telegram - @tospace

This telegram bot is a little bit more than standard "Hello World" application - it does something. It gets the information about closest launches of spacecrafts.

This library was created to illustrate a bot creation process as simple as it possible.

I have created it as a demo for my presentation on IT NonStop Wroclaw. Links and descriptions are going to be provided when event will happen.

Environment

It works literally everywhere. Server is not mandatory - it works well from your personal device.

Running

1. Register your bot with @botfather. It will give you a token
2. Create token file: cp token-example.js token.js
3. Place your token string inside
4. npm install
5. npm start
6. Enjoy. Just type your bot a message in telegram

Warning

It is not production ready solution (I know, it's obvious, but...). In real life it makes sense to use a way more complicated algorithms of language recognition, not indexOf. Also in real life it's a very bad idea to hardcore URLs like it's done in the example. Only morons do so on real projects. Storing cases in one folder is not a good practice either, some architecture is very helpful. Just imagine it's kind of router and cases are action of controllers - with such abstraction life is way easier.
