# Amber/Router [![Build Status](https://travis-ci.org/amberframework/amber-router.svg?branch=master)](https://travis-ci.org/amberframework/amber-router) [![Latest Release](https://img.shields.io/github/release/amberframework/amber-router.svg)](https://github.com/amberframework/amber-router/releases)

A tree based url router with a similar API interface to [radix](https://github.com/luislavena/radix).

## Installation

Add this to your application's `shard.yml`:

```yaml
dependencies:
  amber_router:
    github: amberframework/amber-router
```

## Usage

```crystal
require "amber_router"

route_set = Amber::Router::RouteSet(Symbol).new
route_set.add "/get/", :root

# A `:` at the start of a segment indicates a named parameter
route_set.add "/get/users/:id", :users
route_set.add "/get/users/:id/books", :users_books

# A `*` at the start of a segment indicates a glob parameter
route_set.add "/get/users/comments/*date_range"

# Supports storing multiple named arguments at the same position
route_set.add "/get/users/:user_id/books/:23", :user_book

# Predictably matches by insertion order so route overloads work as expected
route_set.add "/get/books/mine", :my_books
route_set.add "/get/books/:id", :book
route_set.add "/get/books/:id/chapters", :book_chapters

# Supports globs with a suffix
route_set.add "/get/posts/*post_name/comments", :wordpress_style

# Supports match-all globs.
route_set.add "/get/*", :catch_all

# Supports `Regex` based argument constraints
route_set.add "/get/posts/:page", :user_path, {"page" => /\d+/}
route_set.add "/get/test/:id", :user_path, {"id" => /foo_\d/}

route_set.find("/get/posts/1").found? # => true
route_set.find("/get/posts/foo").found? # => false

route_set.find("/get/test/foo_7").found? # => true
route_set.find("/get/test/foo_").found? # => false

# Supports returning an array of matches.
# Allows using custom logic based on each route's payload
# to determine if a match could be found
route_set.add "/user/:id", :user_get
route_set.add "/user/:id", :user_delete
route_set.add "/user/:id/posts", :user_posts_get

route_set.find_routes("/user/10").map &.payload? # => [:user_get, :user_delete]

# Finding routes from a payload:
route_set.find("/get/users/3").payload # => :users
route_set.find("/get/users/3/books").payload # => :users_books
route_set.find("/get/books/3").payload # => :book

# `RoutedResult` returns payload and named parameters
result = route_set.find("/get/posts/my_trip_to_kansas/comments")
result.found? # => true
result.params # => {"post_name" => "my_trip_to_kansas"}
```

## Performance

`crystal run examples/benchmark.cr --release` produces a comparison of this router and [radix](https://github.com/luislavena/radix). As of now, this is the comparison:
