+# Douscord
+
+
+
+​	Created for a study project in <u>Advanced web development</u>, we had to replicate  [Discord](https://discordapp.com/) the famous text/vocal/video streaming platform. We had to use *WebSockets*, the *Java Persistence API* and the option we chose is to support *audio streaming* support. We worked on this project for 3-5 weeks.
+
+
+
+>  This work is under the MIT Licence.
+
+
+
+**LEGAL ISSUES**
+
+​	Discord is an open-source project, but we decided to "*copy*" its behavior without looking at its source. We dumped assets from the original website, any legal issue is protected by non-profit university work.

+- [VueJS](https://vuejs.org/) a javascript template renderer framework to manage highly related components in real-time.
+- [Electron](https://electronjs.org/) to build native cross-platform desktop applications from the client source.
+- [Electron Packager](https://github.com/electron-userland/electron-packager) to build bundled out of the box working applications.
+- [Parcel](https://github.com/parcel-bundler/parcel) bundler to build javascript dependencies for either the browser or electron.
