Example -- Subroutes
====================
The ``routes`` decorator lets you set up different routes easily, but it can be cumbersome to write many similar routes.
If you need to write similar routes, the ``subroute`` function can help.
``subroute`` is a context manager within whose scope all invocations of ``route`` will have a prefix added.
Here is an example app that has routes for ``/branch/lair``, ``/branch/crypt``, and ``/branch/swamp`` all defined in a ``with app.subroute()`` block.
.. code-block:: python
from klein import Klein
app = Klein()
with app.subroute("/branch") as app:
@app.route("/lair")
def lair(request):
return b"These stairs lead to the lair of beasts."
@app.route("/crypt")
def crypt(request):
return b"These stairs lead to an ancient crypt."
@app.route("/swamp")
def swamp(request):
return b"A stair to a swampy wasteland."
app.run("localhost", 8080)
The subroute method is also available globally if that is your preferred klein
pattern.
.. code-block:: python
from klein import run, subroute
with subroute("/branch") as app:
@app.route("/twilightforest")
def twighlightforest(request):
return b"These stairs lead to the twilight forest."
app.run("localhost", 8080)
