-# video-chat
+# video-chat
+> Video chat application using [VueJS](https://vuejs.org), [Vuex](https://vuex.vuejs.org), [WebRTC](https://webrtc.org/start/), [SocketIO](https://socket.io), NodeJS and [Redis](https://github.com/NodeRedis/node_redis)
+
+## Quick start
+First of all, you need to install and run the redis in your PC. Here there is an [article](https://medium.com/@petehouston/install-and-config-redis-on-mac-os-x-via-homebrew-eb8df9a4f298) for Mac OS X. Once Redis is up and running:
+
+```bash
+# Clone the repo
+git clone https://github.com/adrigardi90/video-chat
+
+# Change into the repo directory
+cd video-chat
+
+# install
+npm install 
+
+# Start the FE in dev mode
+npm run serve
+
+# Start the server
+npm run run:server
+
+```
+Then visit http://localhost:8080 in your browser
+
+## Horizontal scaling
+To test the horizontal scaling we need to run two different instances. Each one will run a nodeJS process serving the FE and 
+exposing the API
+

+  <img src="https://github.com/adrigardi90/video-chat/blob/master/src/assets/scaling.png" alt="scaling" width="500" height="250"/>
+</p>
+
+
+```bash
+# Build the images
+docker-compose build
+
+# Create and run the two instances
+docker-compose up
+
+```
+
+Then you'll find on http://localhost:3000 and http://localhost:3001  both FE applications, each one with a different socket connection
