Initializing MtpProxy

The main MTP wrapper class is MtpProxy, since you do not want to login into Telegram each time you run your app, you should implement two fucntions for saving and restoring the state of MtpProxy and pass them to MtpProxy.init method:

import fs from 'fs'
import { MtpProxy } from 'telejs'

MtpProxy.init(
  (state) => new Promise((resolve, reject) => {
    fs.writeFile('state.json', state, 'utf8', (err) => {
      if (err) {
        reject(err)
        return
      }
      resolve()
    })
  }),
  () => new Promise((resolve, reject) => {
    fs.readFile('state.json', 'utf8', (err, data) => {
      if (err) {
        reject(err)
        return
      }
      resolve(data)
    })
  })
  , 'verbose')

After MtpProxy.init is called, your MtpProxy is ready to work.

Signing in

 MtpProxy.signInUser('YOUR PHONE NUMBER HERE', codeInputPromise)
    .then(res => console.log(res))
    .catch((err) => console.error(err))

codeInputPromise - Promise that should return the auth code received from Telegram

Calling Telegram API methods

Please refer to official Telegram API methods list to find available methods.

Here is an example of calling messages.sendMessage method:

MtpProxy.mtpInvokeApi('messages.sendMessage',
        {
            "random_id": Math.floor(Math.random() * 5000),
            "peer": { "_": "inputPeerUser", "user_id": 'USER ID TO SEND MESSAGE TO', "access_hash": "ACCESS HASH" },
            "message": `How are you doing?`
        }
    )
    .then(res => console.log('sent'))
    .catch(err => console.error(err))
