kua

Lightning fast URL routing in Python.

kua is a Trie-like based router. It scales better than regex based routers and due to this it's usually faster.

It's pretty bare bones and it's meant to be used in more feature-rich routers.

Compatibility

• Python 3.5

Install

$ pip install kua

Usage

import kua

routes = kua.Routes()
routes.add('api/:foo', {'GET': my_get_controller})
route = routes.match('api/hello-world')
route.params
# {'foo': 'hello-world'}
route.anything
# {'GET': my_get_controller}

Backtracking

Backtracking means kua will have to try more than one path to match the URL.

This may hurt performance, depending how much backtracking is involved, usually you should not worry about it, though.

This reduces to not placing two variables next to each other and not placing a variable where there is a static one in a similar pattern.

Here are some examples of good and bad schemas:

# bad
routes.add(':var', ...)  # clashes with pretty much every pattern

# still bad
routes.add(':var1/:var2', ...)

# bad
routes.add(':var1/foo', ...)

# still bad
routes.add(':var1/:var2/foo', ...)

# bad
routes.add('api/:var1', ...)
routes.add('api/foo', ...)

# still bad
routes.add('api/:var1/:var2', ...)
routes.add('api/foo', ...)

# still bad
routes.add('api/:var1/foo', ...)
routes.add('api/foo', ...)

# good
routes.add('api', ...)
routes.add('api/:var', ...)
routes.add('api/:var/foo', ...)
routes.add('api/:var/bar', ...)
routes.add('api/:var/foo/:var2', ...)
routes.add('api/:var/bar/:var2', ...)

# good
routes.add('topics', ...)
routes.add('topics/:var', ...)
routes.add('authors', ...)
routes.add('authors/:var', ...)

# good
routes.add('shelf', ...)
routes.add('shelf/books', ...)
routes.add('shelf/books/:var', ...)

# good
routes.add('books/all', ...)
routes.add('books/removed', ...)
routes.add('books/pending', ...)
