Usage

This application assumes that asdf is used to install Erlang and Elixir. Setup the application locally using the following commands:

bin/dev/doctor
bin/dev/start

1. Open two browsers to http://localhost:4000. In one browser, enter a pad id, for example my-note.
2. Copy the url.
3. Paste the url into the second browser.
4. Edit/add text in each browser. Updates should appear in the other browser.
5. Select text in each browser. Cursor/highlights should appear in the other browser.

Known issues

• Adding empty lines of text causes the current cursor to jump around.
• Sometimes the JS for getting the current selection gives back data that doesn't seem to work, either in the current browser or in observing browsers.
