node-telegram-keyboard-wrapper-fix

Node telegram keyboard wrapper

A support for telegram keyboards management, both inline and reply, and forceReply

This libray aims to provide a set of methods and classes to handle keyboards and force replies in node.js-written Telegram bots.

Built upon yagop's node-telegram-bot-api but can virtually work with any node.js telegram bot api wrapper.

Installation

From NPM:

npm install -s node-telegram-keyboard-wrapper

Downloading from Github, won't give the compiled version, so you'll have to do it by yourself.

npm build

Tests for methods used by ReplyKeyboard and InlineKeyboard are included.

# Installing dev dependencies 
npm install -D
npm test

In examples folder, an example bot is available. It requires a bot token to be passed as argument.

npm run example -- 123456:ABC-DEF1234ghIkl-zyx57W2v1u123ew11

Then just type /replyKeyboard (and answer or click to hide), /inlineKeyboard (and click to trigger) or /forceReply in your Telegram client to see the wrapper in action.

If you have any issue, suggestion of what else, feel free to open a topic in issues. 😉
