Route One is a tiny Clojure library that generates HTTP resource routes (as in Ruby on Rails, Jersey, Noir and similar modern Web application frameworks). It is meant to be used in HTTP clients, programs that deliver emails with links, testing environments and so on.
Route One is intentionally small and has very limited feature scope.
With Leiningen:
[clojurewerkz/route-one "1.2.0"]
With Maven:
<dependency>
<groupId>clojurewerkz</groupId>
<artifactId>route-one</artifactId>
<version>1.2.0</version>
</dependency>
Route One requires Clojure 1.4+.
In order to define a route, you can use defroute:
(defroute document "/documents/:document-id")After defining a route, you get several helper functions to work with the route:
document-path builds a relative path with passed params:
(document-path :document-id "123")
;; => "/documents/123"documents-url builds an absolute url:
(with-base-url "https://myservice.com"
(document-url :document-id "123"))
;; => "https://myservice.com/documents/123"document-template gives a template that you can use to match the url in Clout/Compojure or any
other library that uses similar syntax.
document-template
;; => "/documents/:document-id"(ns my.app
(:require [clojurewerkz.route-one.core :refer :all])
;; define your routes
(defroute about "/about")
(defroute faq "/faq")
(defroute help "/help")
(defroute documents "/docs/:title")
(defroute category-documents "/docs/:category/:title")
(defroute documents-with-ext "/docs/:title.:ext")
;; generate relative paths (by generated fns)
(documents-path :title "a-title") ;; => "/docs/a-title"
(documents-path :title "ohai") ;; => "/docs/ohai"
(path-for "/docs/:category/:title" { :category "greetings" :title "ohai" }) ;; => "/docs/greetings/ohai"
(path-for "/docs/:category/:title" { :category "greetings" }) ;; => IllegalArgumentException, because :title value is missing
(with-base-url "https://myservice.com"
(url-for "/docs/title" { :title "ohai" }) ;; => "https://myservice.com/docs/title"
(url-for "/docs/:title" { :title "ohai" }) ;; => "https://myservice.com/docs/ohai"
(url-for "/docs/:category/:title" { :category "greetings" :title "ohai" }) ;; => "https://myservice.com/docs/greetings/ohai"
(url-for "/docs/:category/:title" { :category "greetings" }) ;; => IllegalArgumentException, because :title value is missing
)
;; generate relative paths (by generated fns)
(with-base-url "https://myservice.com"
(documents-url :title "a-title") ;; => "https://myservice.com/docs/a-title"
(documents-url :title "a-title" :category "greetings") ;; => "https://myservice.com/docs/greetings/a-title"
)Use your templates with Compojure/Clout (they're not present as a dependency, but we support same path structure):
(ns my-app
(:require [compojure.core :as compojure]
[compojure.route :as route])
(:use [clojurewerkz.route-one.core))
(defroute about "/about")
(defroute documents "/docs/:title")
(compojure/defroutes main-routes
(compojure/GET about-template request (handlers.root/root-page request)) ;; will use /about as a template
(compojure/GET documents-template request (handlers.root/documents-page request)) ;; will use /docs/:title as a template
(route/not-found "Page not found"))You can also use our overrides of Compojure functions that allow you to build named routes with Compojure:
(ns my-app
(:require [compojure.core :as compojure])
(:use clojurewerkz.route-one.compojure))
(compojure/defroutes main-routes
(GET about "/about" request (handlers.root/root-page request)) ;; will use /about as a template
(GET documents "/docs/:title" request (handlers.root/documents-page request)) ;; will use /docs/:title as a template)That will generate main-routes in same exact manner Compojure generates them, but will also add helper functions
for building urls (about-path, about-url, documents-path, document-url and so on). For that, you'll have to
bring in Compojure as a dependency yourself:
[compojure "1.1.5"]Documentation site for Route One is coming in the future (sorry!). Please see our test suite for more code examples.
Route One is part of the group of libraries known as ClojureWerkz, together with Cassaforte, Monger, Langohr, Elastisch, Quartzite, and several others.
CI is hosted by travis-ci.org
Route One uses Leiningen 2. Make sure you have it installed and then run tests against all supported Clojure versions using
lein all test
Then create a branch and make your changes on it. Once you are done with your changes and all tests pass, submit a pull request on Github.
