Commently

A simple text commentig app for the web.

Installation

This app is created with Meteor.js and utilizes rangy.

To install the app, first follow the instructions to install Meteor

curl https://install.meteor.com/ | sh

and then:

1. git clone https://github.com/valeviolin/commently.git
2. meteor npm install
3. meteor

the following will have the app running on localhost:3000

The main logic of the app can be found in main.js.

The approach taken roughly follows the following:

Before each action "restore" the DOM state of the text. E.g remove highlights
For new comments, create a Mongo document with the comment's text and the serialized range of the selected text.
After clicking on a comment, deserialize the range of the comment and highlight it.

There are some bugs here and there (which I could not spot easily) due to either rangy or myself not fully getting rangy's way of working.

This is only tested on the latest Chrome browser.
