The comprehensive WSGI web application library.
Werkzeug
werkzeug German noun: "tool". Etymology: werk ("work"), zeug ("stuff")
Werkzeug is a comprehensive WSGI_ web application library. It began as
a simple collection of various utilities for WSGI applications and has
become one of the most advanced WSGI utility libraries.
It includes:
- An interactive debugger that allows inspecting stack traces and source code in the browser with an interactive interpreter for any frame in the stack.
- A full-featured request object with objects to interact with headers, query args, form data, files, and cookies.
- A response object that can wrap other WSGI applications and handle streaming data.
- A routing system for matching URLs to endpoints and generating URLs for endpoints, with an extensible system for capturing variables from URLs.
- HTTP utilities to handle entity tags, cache control, dates, user agents, cookies, files, and more.
- A threaded WSGI server for use while developing applications locally.
- A test client for simulating HTTP requests during testing without requiring running a server.
Werkzeug is Unicode aware and doesn't enforce any dependencies. It is up to the developer to choose a template engine, database adapter, and even how to handle requests. It can be used to build all sorts of end user applications such as blogs, wikis, or bulletin boards.
Flask_ wraps Werkzeug, using it to handle the details of WSGI while
providing more structure and patterns for defining powerful
applications.
