@puregram/utils v1.0.1

@puregram/utils

Package, containing some useful utilities for puregram package

Introduction

This package exists only for one main reason: basically not everyone wants to have such utils as getCasinoValues and <insert one more here> when installing puregram, so these functions were moved to separated package

Example

const { Telegram } = require('puregram');
const { getCasinoValues } = require('@puregram/utils');

const telegram = new Telegram({
  token: process.env.TOKEN
});

telegram.updates.on('message', (context) => {
  if (context.hasDice && context.dice.emoji === '🎰') {
    console.log(getCasinoValues(context.dice.value)); // e.g. ['seven', 'bar', 'grapes']
  }
});

telegram.updates.startPolling();

Installation

$ yarn add @puregram/utils
$ npm i -S @puregram/utils
