Prerequisites: Docker

Install nvidia-container-runtime to use GPU inside Docker containters as follows. Actually, you can skip this part and remove "deploy" section in compose.yaml. But in this case, the track processing time will increase significantly, so better do it, if you have a GPU. You can also skip this step and run celery worker locally without Docker (see "Running backend locally").

curl -fsSL https://nvidia.github.io/libnvidia-container/gpgkey | sudo gpg --dearmor -o /usr/share/keyrings/nvidia-container-toolkit-keyring.gpg \
  && curl -s -L https://nvidia.github.io/libnvidia-container/stable/deb/nvidia-container-toolkit.list | \
    sed 's#deb https://#deb [signed-by=/usr/share/keyrings/nvidia-container-toolkit-keyring.gpg] https://#g' | \
    sudo tee /etc/apt/sources.list.d/nvidia-container-toolkit.list
sudo apt-get update
sudo apt-get install -y nvidia-container-toolkit
sudo systemctl restart docker

How to run the system:

git clone https://github.com/m-danya/accompanist
cd accompanist
cp .env.sample .env

Since this project uses Genius API for obtaining lyrics for tracks, you need to get token for Genius API. In can be done in 90 seconds:

Go to https://genius.com/api-clients and obtain Client Access Token. You can enter any app name an use any "App Website URL". After you get the token, place it into your .env file (corresponding variable is GENIUS_CLIENT_ACCESS_TOKEN).

Let's continue:

mkdir storage-volume
docker-compose up -d --build
docker exec -it accompanist-backend-1 alembic upgrade head
# open http:https://localhost in your browser

This project uses ruff for formatting and linting. For VS Code, just install the "Ruff" extension and reload the editor.

If you're using VS Code, install these extensions for frontend development: "Vue Official" and "Prettier".

The .vscode/launch.json file is included in this repo to help developers to easily run the frontend and backend locally. To run the system locally, you need to follow the instructions both above and below this paragraph.

If you want to run backend and frontend without Docker, you still need these containers to be running:

docker compose up -d nginx db rabbitmq

You can view the current Celery tasks queue using Flower on http:https://localhost:5555.

You can access the admin panel at http:https://localhost:8000/admin.

cd frontend
nvm install 20
nvm use 20
npm install
# run "Vue.js" configuration in VS code or:
npm run serve

sudo apt install python3.10 python3.10-venv
python3.10 -m venv venv
source venv/bin/activate
poetry install

# 1. Running FastAPI backend
# run "FastAPI" configuration in VS code or:
STORAGE_PATH=./storage-volume uvicorn accompanist.main:app --reload

# 2. Running Celery  worker for processing albums
# run "Celery worker" configuration in VS code or:
STORAGE_PATH=./storage-volume celery -A accompanist.celery.main.app worker --loglevel info -E

You may want to deploy this app in your local network, for example, to access it from your mobile device, connected to the same Wi-Fi network. In this case, just change the DEPLOYMENT_HOST variable in your .env file from 127.0.0.1 to your local IP address (look for an IP address like 192.168.1.7 in the output of ifconfig). After docker compose up -d --build, you will be able to access the system at ${DEPLOYMENT_HOST}:${DOCKER_FRONTEND_PORT}.

• [All the "TODO"s in the code]
• DragAndDrop albums at the main page
• Fix admin panel being available only at ${FASTAPI_PORT} but not at ${NGINX_PORT}
• Tune Genius search query (e.g. remove the parentheses in track title)
• Skip banned tracks from album
• Show albums/tracks collection with filters
  • Extract TrackLine component to reuse in collection
  • Sort by cover colors (just for fun)
• Descriptive error messages on frontend (e.g. for Genius API)
• Add paging for albums & tracks
• Put vocals track into "practice mode", mix with karaoke?
• Add router to frontend (to support links like /album/123)
• Show track name in page title
• Shuffle mode (for karaoke-labeled tracks with autoplay)
• Download tracks' studio versions (ignore clip versions from YT Music)
• Collection management: order of albums / stars / rating
• Add editing text from frontend (to edit Genius parser's mistakes)
• Run alembic upgrade head at launching?
• Publish docker image(s) to Docker Hub
• Different gradient backgounds for different songs (random + choosing)
• Frontend localization
• Add Telegram bot wrapper for the backend
• Add mypy (+ CI)
• Add tests
