telegram-mtproto

Telegram Mobile Protocol (MTProto) library in es6

About MTProto..

MTProto is the Telegram Messenger protocol "designed for access to a server API from applications running on mobile devices".

The Mobile Protocol is subdivided into three components (from the official site):

• High-level component (API query language): defines the method whereby API queries and responses are converted to binary messages.

• Cryptographic (authorization) layer: defines the method by which messages are encrypted prior to being transmitted through the transport protocol.

• Transport component: defines the method for the client and the server to transmit messages over some other existing network protocol (such as, http, https, tcp, udp).

telegram-mtproto in short..

No more additional libs. The telegram-mtproto library implements the Mobile Protocol and provides all features for work with telegram protocol:

• A high level api for server connection

• Promise-based API

• Both TCP and HTTP connections implemented in the transport layer

• A cipher implementation for AES and RSA encryption in the security layer

• Both plain-text and encrypted message to communicate data with the server

• Diffie-Hellman key exchange supported by the prime factorization function implemented in the security layer

• MTProto TL-Schema compilation as javascript classes and functions

Usage

const { Telegram, network } = require('telegram-mtproto')

const fileSchema = require('./api-schema-57.json')

const telegram = new Telegram(fileSchema)
const addKey = key => telegram.addPublicKey(key)
publicKeys.forEach(addKey)

const connection = new network.http(server)
const client = telegram.createClient()

client.setConnection(connection)
connection.connect()
  .then(() => console.log(`api ready for requests`))
  .then(() => client.callApi('auth.sendCode', {
    phone_number  : phone.num,
    current_number: false,
    api_id        : config.id,
    api_hash      : config.hash
  }).then(
  ({ phone_code_hash }) =>
    client.callApi('auth.signIn', {
      phone_number   : phone.num,
      phone_code_hash: phone_code_hash,
      phone_code     : phone.code
    }))
