👤 tg-resolve

A light Node.js Library that resolves Telegram usernames and/or ids to a complete User or/and Chat JSON object(s)

Powered by PWRTelegram API

Background

The official Telegram API does not allow bots to resolve usernames/ids out of the box. One is forced to create his/her own database so as to resolve usernames. Resolving of usernames is particularly useful in that a bot is able to get a user/chat id of a person or groub it hasn't even seen! Unlike before where a bot is only able to see a person if it has ever recieved his/her message whether in private or in a group.

Useful Scenarios

• Group administration bots
• In a bot which has lost its database, but users had previously started the bot
• General resolving to get user details e.g UResolverBot
• And much more!

Install

$ npm install tg-resolve --save

Usage

const tgresolve = require("tg-resolve");

// using the 'bare' function
tgresolve(token, "@kamikazechaser", function(error, result) {
    // ... handle error ...
    console.log(result.id);
});

// you can create a client (referred to as 'resolver')
// that you can repeatedly use
const resolver = new tgresolver.Tgresolve(token);

// using the 'resolver'
resolver.tgresolve("@kamikazechaser", function(error, result) {
    // ... handle error ...
    console.log(result.id);
});
