Discoo.dog is a web application with the main features of Discord and Moodle. It can be used by students to chat, voice chat, check announcements, and discuss with their teachers.

It has a similar interface to discord, with channels, servers, WebRTC voice and video chat.

Discoo.dog is a fully dynamic web application. It is almost 100% javascript. Which makes it asynchronous and way faster. Since it's a web app, it can also be multiplatform or implemented into a standalone executable as in Discord (using Electron).

Front end : HTML5, Javascript, CSS.

Back end : NodeJs, SQL.

1. Express Server (HTTP Requests)
2. Mutler (File Upload)
3. Socket.io (WebSockets)
4. bCrypt (Back-end encryption)
5. CookieParser (Back-End cookie parser)
6. MySQL (SQL)
7. HandShake (Client-Server middleware)
8. PeerJS (Peer-to-Peer WebRTC for voice and video)

In order to run discoo.dog, you need (Linux Terminal):

1) Npm : apt install npm

2) NodeJs : apt install nodejs

3) MySql : apt install mysql

In order to run discoo.dog, you need (Mac Terminal):

1) Npm : brew install npm

2) NodeJs : brew install nodejs

3) MySql : brew install mysql

If you're running this for the first time, you need to setup your mysql database. Execute these lines in order in the git folder :

mysql -u root -p
CREATE DATABASE discoodle;
USE discoodle
SOURCE discoodle.sql

PS: You can use PhpMyAdmin for an easier mysql database setup.

Then, we need to install npm prerequisites and run the local server. Execute these lines in order in the git folder :

npm install
npm start

But you may have problems here, this is probably due to the bcrypt library. If this happens, please follow these commands

sudo npm install
sudo npm uninstall bcrypt
sudo npm install bcrypt
sudo npm start

If the console logs Server started, we can open a web browser and type the url:

localhost:5000

You can also go directly to : https://discoo.dog:5000

After logging in, you are redirected to the home page. You see the main news displayed to your screen. You can access, from the navigation bar :

1. Profile : Here you will have all the info related to your profile (Username, email, etc...). You can also change your profile picture.

2. Messages : Here you can access the main web application. You can consult courses, chat in realtime, access realtime voice and video chat (one room for each course), upload images, etc...

3. Write an article : Here you can access the page to write an article. The article will be then displayed on the public home page.

4. Teacher's panel : Here you can access the teacher's panel. Teacher can assign student to courses, create / delete courses etc...

5. Admin panel : If you are admin, you can access the admin panel. You can change users roles.

Discoo.dog works with a role hierarchy.

Every user can either be an admin, a teacher or a student.

Admin > Teacher > Student.

Account created have the student role by default.

The user admin can administer the whole server and manage users and professors (You can access the administration panel from the home page ).

The user teacher can administer the classes, courses and modules (You can access the professor panel from the home page ).

The user student can join a class. Class which are composed of different courses themselves composed of different modules

Examples : You have three different accounts created by default :

1. admin@admin.com with the password admin
2. teacher@teacher.com with the password teacher
3. student@student.com with the password student

Discoo.dog uses dynamic hierarchy, and can be used by multiple establishements / servers / licenses.

An example of a possible hierarchy :

L1 Info -> Modules of L1 Info -> Courses for each module of L1 Info + Different chat channel + A unique voice chat room.

You can dynamically adjust the hierarchy to basicly fit whatever your needs are using the admin panels.

1. Students can only see the servers and the courses they are assigned to (by themselves, teachers or admins).
2. Teachers can only see the servers and the courses they are assigned to, and they can write announcements or information in the courses rooms. Students can see the rooms but cannot write in them.
3. Admins can see all the servers and all the courses. They can assign anything to anyone. They basicly have every permission on the server.

1. Real time WebSocket chat with custom profile pictures and sent dates.

2. Real time WebSocket image upload and display. Images are stored server side and on the database and are served to every user.

3. Server - Channel - Chat hierarchy. Dynamic. Can be used for a wide range of projects (Like Discord and Slack.)

4. Client side custom SQL API. Can interact with database anywhere in any file to get and display data.

5. Real time calling with voice and camera. Private rooms for any course. Can have multiple rooms for multiple courses at the same time.

6. HTTPS certificate on discoo.dog - needed for modern browsers to allow Peer to Peer voice / video chat.

7. Permission system with Admin, Teacher and Student panels. Depending on the roles, they can change roles, assign to courses, create courses, create articles etc...

8. Profile page, to display information about the current user, and change the profile picture and update it to the whole server.

9. Home page displaying the last information and updates to the user. Teachers and admins can add articles on the home page using the "write articles" page.

10. Full Login / Register, Session cookies, safe database with encrypted passwords. No need to reconnect everytime you join discoo.dog.

Discoo.dog is a 100% JavaScript, HTML and CSS web app. This means it can be implemented easily on Electron, and be an executable file like Discord, Spotify, Slack, VSCode etc...

A web browser wouldn't be needed anymore.
