# 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 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.
