Routex.Extension.Cloak (Routex v1.2.2)

View Source

Transforms routes to be unrecognizable.

Warning

This extension is intended for testing and demonstration. It may change at any given moment to generate other routes without prior notice.

The Cloak extension demonstrates how Routex enables extensions to transform routes beyond recognition without breaking Phoenix' native and Routex' routing features.

Currently it numbers all routes. Starting at 1 and incremening the counter for each route. It also shifts the parameter to the left; causing a chaotic route structure.

Do note: this still works with the Verified Routes extension. You can use the original, non transformed, routes in templates (e.g. ~p"/products/%{product}") and still be sure the transformed routes rendered at runtime (e.g. /88/2 when product.id = 88) are valid routes.

Do (not) try this at home

  • Try this extension with a route generating extension like Routex.Extension.Alternatives for even more chaos.

  • Adapt this extension to use character repetition instead of numbers. Can you guess where /90/** leads to?

Configuration 

# file /lib/example_web/routex_backend.ex
defmodule ExampleWeb.RoutexBackend do

Pseudo result 

Original                 Rewritten    Result (product_id: 88, 89, 90)
/products                ⇒     /1     ⇒    /1
/products/:id/edit       ⇒ /:id/2     ⇒ /88/2, /89/2, /90/2 etc...
/products/:id/show/edit  ⇒ /:id/3     ⇒ /88/3, /89/3, /90/3 etc...
