DHBW socket.io sample

This sample was done for a socket.io presentation with a chat sample live coding at the Cooperative State University Baden-Wuerttemberg Heilbronn.

Slides can be viewed at Speaker Deck.

Prerequisites

• Install Node.js.
• After installing Node.js, execute npm i in the root of this repository to install socket.io dependency.

Run it

To run the sample you need to start both client and server:

• npm run start-server starts a server on http://localhost:3000.
• npm run start-client starts a static file server on http://localhost:8080.

After starting both, go point two browsers to http://localhost:8080. They connect to the WebSocket server allowing to send very simple chat messages. Enjoy!
