Unslash

Unslash is a Crystal HTTP handler that removes slashes (/) at the end of URLs, performing a redirect to the unslashed version of the same URL.

This, among others, improves SEO by avoiding duplicated content across the different versions of the same URL.

Installation

1. Add the dependency to your shard.yml:

   dependencies:
     unslash:
       github: GrottoPress/unslash
   

2. Run shards update

3. Require Unslash:

   # ...
   require "unslash"
   # ...
   

Usage

Pass an instance of Unslash::Handler to the web server. If using a web framework, this handler should be passed before the framework's route handler:

# ...
require "http/server"
require "unslash"

server = HTTP::Server.new([
  # If `safe` is `true`, only `GET` and `HEAD` request methods
  # are handled.
  Unslash::Handler.new(status_code: 308, safe: false),
  # ...
])

server.bind_tcp("127.0.0.1", 8080)
server.listen
# ...

Development

Run tests with crystal spec.
