qdp

qdp is a local Qobuz toolkit with an existing CLI/TUI downloader workflow and a local web player runtime.

Sprint 1 establishes the delivery baseline by documenting scope, backup rules, runnable commands, and packaging metadata.

What is in this repository

• CLI entrypoint: qdp/__main__.py and qdp/cli.py
• Interactive UI/TUI: qdp/ui.py
• Account management: qdp/accounts.py
• Local web player server: qdp/web/server.py
• Browser app assets: qdp/web/app/
• Automated tests: tests/
• Packaging files: setup.py, qdp.spec, build_windows.*

Requirements

• Python 3.9+
• pip
• Qobuz account credentials/config available locally

Install

Create a virtual environment and install runtime dependencies:

python3 -m venv .venv
source .venv/bin/activate
python -m pip install --upgrade pip setuptools wheel
python -m pip install -r requirements.txt
python -m pip install -e . --no-build-isolation

Environment / Credentials

Example variables are in .env.example.

The current application also reads account/config data from the local qdp config flow, especially for authenticated web-player actions.

Run

CLI / TUI

qdp

or

python -m qdp

First-time setup:

qdp -r

The config wizard will guide you through login method, key selection (default Android key / auto-fetch web key / manual App ID & Secret), download directory, and quality preference.

Quick commands

qdp -s "query"          # search all
qdp -sa "album name"    # search albums
qdp -st "track name"    # search tracks
qdp "https://www.qobuz.com/album/xxxxx"  # download from URL
qdp --version            # show version (114.0.1)
qdp --help               # show help (works without config)

Web player

python3 -m qdp.web.server

The server prints a listening URL such as QDP web server listening on http://127.0.0.1:17890/ and keeps running until you stop it.

A reproducible local smoke sequence for the backend runtime is:

curl -i http://127.0.0.1:17890/
curl -i http://127.0.0.1:17890/app/
curl -i http://127.0.0.1:17890/nope
curl -i http://127.0.0.1:17890/stream
curl -i 'http://127.0.0.1:17890/api.json/0.2/test?x=1'
python3 scripts/webplayer_smoke.py --json
python3 -m pytest -q tests/test_web_server_runtime.py tests/test_web_player_frontend_contract.py tests/test_webplayer_smoke_cli.py

webplayer_smoke.py defaults to auto-starting a local Web Player, and also supports:

• python3 scripts/webplayer_smoke.py --json — auto-start + machine-readable JSON output
• python3 scripts/webplayer_smoke.py --base-url http://127.0.0.1:17890 --no-start — reuse an existing server instance
• python3 scripts/webplayer_smoke.py --base-url http://127.0.0.1:17890 --no-start --json — reuse an existing instance with stable JSON output

Expected results:

• / redirects to /app/
• /app/ returns 200
• /nope returns 404
• /stream without url returns 400
• /api.json/0.2/test?x=1 returns 200 and JSON describing the active proxy/runtime contract
• webplayer_smoke.py --json returns parseable JSON and validates runtime version consistency, core API routes, stream proxy behavior, and the frontend DOM contract

Proxy Configuration

Add a proxies field in ~/.config/qobuz-dl/config.ini (or via the config wizard):

[DEFAULT]
proxies = https://proxy1.example.com,https://proxy2.example.com

Downloads and API requests automatically rotate through proxies. Falls back to direct connection if all proxies fail.

Bundle / Web Key

The bundle.py module fetches Qobuz web keys. Default upstream is play.qobuz.com (official). Set QDP_BUNDLE_URL env var to use a custom mirror.

Supported runtime environment variables:

• QDP_WEB_HOST — bind host for the local HTTP server
• QDP_WEB_PORT — bind port for the local HTTP server
• QDP_BUNDLE_URL — custom Qobuz mirror URL for web key fetching
• QDP_APP_ID or QOBUZ_APP_ID — Qobuz application ID used by proxy routes
• QDP_AUTH_TOKEN, QOBUZ_AUTH_TOKEN, or QOBUZ_USER_AUTH_TOKEN — auth token forwarded to authenticated Qobuz API calls
• QDP_USER_AGENT or QOBUZ_USER_AGENT — user agent used for upstream API, asset, and stream requests
• QDP_USE_TOKEN or QOBUZ_USE_TOKEN — optional token-mode override

Test

Run the existing automated test suite from the repository root:

pytest -q

The repository now ships pytest.ini so backup folders are not collected as tests.

Local-only build outputs and caches such as build/, dist/, __pycache__/, .pytest_cache/, and virtualenv directories should not be committed; they are safe to regenerate during local packaging or test runs.

If pytest is not installed yet:

python -m pip install -r requirements-build.txt
pytest -q

Packaging

Install build dependencies:

python -m pip install -r requirements-build.txt

Build with PyInstaller:

python -m PyInstaller --clean --noconfirm qdp.spec

Preferred portable helper (works on Unix-like shells and auto-detects python3 when python is unavailable):

./build_windows.sh

The helper now:

• creates an isolated .venv-build virtual environment
• installs runtime and build dependencies
• runs python -m PyInstaller --clean --noconfirm qdp.spec
• verifies that dist/qdp/qdp, dist/qdp/qdp.exe, or legacy flat dist/qdp(.exe) exists
• smoke-checks the artifact with --help before declaring success

Platform helpers:

• build_windows.bat
• build_windows.ps1
• build_windows.sh

Webapp Maintenance

The web-facing layer now has a dedicated maintenance note:

• docs/webapp-maintenance.md

This area is mainly aligned with Kerry's contribution scope: web UI, browser interaction, and frontend-facing maintainability.

Webapp Demo

• Live demo: https://3d970eb7.qdp-webapp-demo.pages.dev/app/
• Deployment URL: https://3d970eb7.qdp-webapp-demo.pages.dev/app/
• Latest UI: v2.13.0 (refresh-safe app routes, mobile search chips, search history, artist-page multi-breakpoint cleanup)
• Last refreshed: 2026-06-15
• Demo mode: Static mock demo on Pages (UI/interaction showcase; not backed by a live qdp Python runtime)

Webapp Preview

Desktop search route with persistent URL and restored artist results:

Artist detail with back navigation, sticky paging info, and denser album grid:

Mobile search now has its own visible search box and focus-triggered type chips:

TUI Preview
