Realtime Todo application developed with Kemal and Websockets

Todo Basic App (Crystal - Kemal - WebSockets)

Requirements

• Crystal 0.18.7

Installation

Before you can run this program you have to install the packages that it uses. You do that with $ shards install.

Run Project

You can run this program in two ways:

1. Compile/build the project using the command line with $ crystal build src/notes.cr --release and run the executable $ ./notes.
2. Run the program with $ crystal src/notes.cr (no compilation required).

*The second is preferred for development.

Once you have run the program, you can open a browser window at localthost:3000 and see the actual app. You can open the app in several browser windows and see how they change in real time via websockets.

*Take in mind that this is just a dummy app written in few hours as a proof of concept.
