Web API Utils for Werkzeug

wau - Web API Utils

Web API Utils, or short wau, is a thin layer on top of Werkzeug to provide a simple and consistent interface for writing APIs in Python. wau is built for educational purposes and is not intended for production use. It is opinionated, as it only supports JSON as data format. It uses simple type annotations to define the expected input and output of the API endpoints. Common tasks as authentication, CORS and server-sent events are supported out of the box.

Installation

Install from PyPI:

pip install wau

or with uv:

uv add wau

Serving static files

run() can serve a static front-end next to your API. Pass static=True to serve files from the directory of the calling script, or static="some/dir" to serve a specific directory:

from wau import run

run(api, static=True)

Only an allow-listed set of file types is served by default (HTML, CSS, JavaScript, images, fonts, ...), so source code and dotfiles such as .env are never exposed. Adjust the allowed file-name globs with static_include and static_exclude (static_exclude takes precedence):

run(api, static=True, static_include=("*.html", "*.css", "*.js"))

While static serving is enabled, the served pages reload automatically in the browser whenever a file changes. This uses the optional watchdog package when it is installed and falls back to polling otherwise. Both this browser reload and Werkzeug's Python source reloader are controlled by use_reloader (on by default); set use_reloader=False to disable them.

Testing

Test dependencies are separated from runtime dependencies in pyproject.toml using the test dependency group.

Run the test suite:

uv run --group test python -m pytest -q

Run doctests:

uv run --group test python -m doctest .\wau.py

Publishing

Build package artifacts:

uv build

Validate metadata and README rendering:

uvx twine check dist/*

Upload to TestPyPI first:

uv publish --publish-url https://test.pypi.org/legacy/

Then publish to PyPI:

uv publish
