Module: Beacon::PathNormalizer

Defined in:
lib/beacon/path_normalizer.rb

Overview

Path normalization fallback — normative, see .doc/definition/06-http-api.md.

Used when the host framework does not expose a route template. Rails apps should set env from the routes layer; everything else falls back to this heuristic.
