During my work on this project I practiced with the technologies:

• asyncio;
• aiohttp;
• PostgreSQL;
• SQLAlchemy;
• websockets.

This is a small site with a radio stream translated from an icecast server with mpd. There is a possibility to vote for the next track after login.

What to do to make it work:

Install and configure postgres (Ubuntu):

sudo apt install postgresql
sudo -i -u postgres
psql
CREATE USER radio_admin WITH PASSWORD 'radio_admin';
CREATE DATABASE radio_logins;

To exit from psql and postgres user:

\q
exit

After that create all the tables in the database with this: python init_db.py

Install and configure icecast and mpd:

sudo apt install icecast2
sudo apt install mpc mpd

Mpd doesn't create folders and files for its correct working, so you need to do this:

mkdir ~/.config
mkdir ~/.config/mpd
touch ~/.mpd/{mpd.db,mpd.log,mpd.pid,mpdstate}

Configs for mpd and Icecast you can take from 'Icecast and mpd configs' folder. Put the config for Icecast in '/etc/icecast2/icecast.xml' and the config for mpd 'in ~./config/mpd/mpd.conf'.

Start icecast with 'sudo systemctl enable icecast2.service'. Start mpd with 'mpd ~./config/mpd/mpd.conf' After that populate mpd database with the command 'mpc update', then add music to the playlist with 'mpc ls | mpc add'. Then start the server with 'python main.py'.
