express-errors-to-telegram

Express error handling middleware for reporting application errors to Telegram. Fully supports typescript.

Setup

1) Obtain new bot token via @BotFather 2) Create a public channel and add your bot to the channel. After step 3 you can make channel private. 3) Open https://api.telegram.org/bot<botToken>/getChat?chat_id=@<channel> where botToken is token obtained at step 1 and channel is channel name created at step 2. From response you need number from id field (e.g. -10014XXX54925):

{"ok":true,"result":{"id":-1001411154925,"title":"<yout channel title>","username":"<your bot name>","type":"channel"}}

Now, when you have botToken and chat_id you can use it in your application.
