Yup, that's it. No magic, no bullshit. \n\n## Installation\n\n[![Clojars Project](https://img.shields.io/clojars/v/org.clojars.askonomm/ruuter.svg)](https://clojars.org/org.clojars.askonomm/ruuter)\n\n## Articles\n\n- [Routing with Ruuter in a Reagent / Re-frame project](https://nth.ee/blog/routing-with-ruuter-in-a-reagent-re-frame-project/)\n\n## Usage\n\n### Setting up\n\nRequire the namespace `ruuter.core` and then pass your routes to the `route` function along with the current request map, like this:\n\n```clojure\n(ns myapp.core\n  (:require [ruuter.core :as ruuter]))\n\n(def routes [{:path \"/\"\n              :method :get\n              :response {:status 200\n                         :body \"Hi there!\"}}])\n\n(def request {:uri \"/\"\n              :request-method :get})\n\n(ruuter/route routes request) ; =\u003e {:status 200\n                              ;     :body \"Hi there!\"}\n```\n\nThis will attempt to match a route with the request map and return the matched route' response. If no route was found, it will attempt to find a route that has a `:path` that is `:not-found`, and return its response instead. But if not even that route was found, it will simply return a built-in 404 response instead.\n\nNote that the `request-method` doesn't have to be a keyword, it can be anything that your HTTP server returns. But it does have to be called `request-method` for the router to know where to look for. That said, you do not have to provide neither `method` in the route, nor `request-method` in the request if you don't want to. You can skip both of them and let Ruuter route based on the `:uri` alone if you want.\n\n### Setting up with [http-kit](https://github.com/http-kit/http-kit)\n\nNow, obviously on its own the router is not very useful as it needs an actual HTTP server to return the responses to the world, so here's an example that uses [http-kit](https://github.com/http-kit/http-kit):\n\n```clojure\n(ns myapp.core\n  (:require [ruuter.core :as ruuter]\n            [org.httpkit.server :as http]))\n\n(def routes [{:path \"/\"\n              :method :get\n              :response {:status 200\n                         :body \"Hi there!\"}}\n             {:path \"/hello/:who\"\n              :method :get\n              :response (fn [req]\n                          {:status 200\n                           :body (str \"Hello, \" (:who (:params req)))})}])\n\n(defn -main []\n  (http/run-server #(ruuter/route routes %) {:port 8080}))\n```\n\n### Setting up with [Ring + Jetty](https://github.com/ring-clojure/ring)\n\n[Ring + Jetty](https://github.com/ring-clojure/ring) set-up is almost identical to the one of http-kit, and looks like this:\n\n```clojure\n(ns myapp.core\n  (:require [ruuter.core :as ruuter]\n            [ring.adapter.jetty :as jetty]))\n\n(def routes [{:path \"/\"\n              :method :get\n              :response {:status 200\n                         :body \"Hi there!\"}}\n             {:path \"/hello/:who\"\n              :method :get\n              :response (fn [req]\n                          {:status 200\n                           :body (str \"Hello, \" (:who (:params req)))})}])\n\n(defn -main []\n  (jetty/run-jetty #(ruuter/route routes %) {:port 8080}))\n```\n\n### Setting up with [Babashka](https://github.com/babashka/babashka)\n\nYou can also use Ruuter with [Babashka](https://github.com/babashka/babashka), by using the built-in http-kit server, for example. Either add the dependency in your `bb.edn` file or if you want to make the whole thing one-file-rules-them-all, then load it in with `deps/add-deps`, like below:\n\n```clojure\n#!/usr/bin/env bb\n\n(deps/add-deps '{:deps {org.clojars.askonomm/ruuter {:mvn/version \"1.3.4\"}}})\n\n(require '[org.httpkit.server :as http]\n         '[babashka.deps :as deps]\n         '[ruuter.core :as ruuter])\n\n(def routes [{:path \"/\"\n              :method :get\n              :response {:status 200\n                         :body \"Hi there!\"}}])\n\n(http/run-server #(ruuter/route routes %) {:port 8082})\n\n@(promise)\n```\n\n### Creating routes\n\nLike mentioned above, each route is a map inside a vector - the order is important only in that the route matcher will return the first result it finds according to `:path`. \n\nEach route consists of three items:\n\n#### `:path`\n\nA string path starting with a forward slash describing the URL path to match. \n\nTo create parameters from the path, prepend a colon (:) in front of a path slice like you would with a Clojure keyword. \n\n##### Required parameters\n\nA required parameter with a string such as `/hi/:name`, which would match any string that matches the `\\/hi\\/.*` regex in the URI, in its own slice. The `:name` itself will then be available with its value from the `request` passed to the response function, like this:\n\n```clojure\n(fn [req]\n  (let [name (:name (:params req))]\n    {:status 200\n     :body (str \"Hi, \" name)}))\n```\n\n##### Optional parameters\n\nA optional parameter with a string such as `/hi/:name?`, which would match any string that matches the `\\/hi\\/?.*?` regex in the URI, in its own slice. If there is a `:name` provided in the URI then it will then be available with its value from the `request` passed to the response function, like this:\n\n```clojure\n(fn [req]\n  (let [name (:name (:params req))]\n    {:status 200\n     :body (str \"Hi, \" name)}))\n```\n\n##### Wildcard parameters\n\nThe above-mentioned `:name` and `:name?` only match in its own path slice, e.g inside a space surrounded by two forward slashes. They cannot, by design, match the whole URL path. If you need wildcard matching, instead use `:name*`, which will match everything, including forward slashes.\n\n#### `:method`\n\nThe HTTP method to listen for when matching the given path. This can be whatever the HTTP server uses. For example, if you're using http-kit for the HTTP server then the accepted values are:\n\n- `:get`\n- `:post`\n- `:put`\n- `:delete`\n- `:head`\n- `:options`\n- `:patch`\n\n#### `:response`\n\nThe response can be a direct map, or a function returning a map. In case of a function, you will also get passed to you the `request` map that the HTTP server returns, with added-in `:params` that contain the values for the URL parameters you use in your route's `:path`.\n\nThus, a `:response` can be a map:\n\n```clojure\n{:status 200\n :body \"Hi there!\"}\n ```\n\nOr a function returning a map:\n\n```clojure\n(fn [req]\n  {:status 200\n   :body \"Hi there!\"})\n ```\n\nWhat the actual map can contain that you return depends again on the HTTP server you decided to use Ruuter with. The examples I've noted here are based on [http-kit](https://github.com/http-kit/http-kit) \u0026 [ring + jetty](https://github.com/ring-clojure/ring), but feel free to make a PR with additions for other HTTP servers.\n\n## Changelog\n\n### 1.3.4\n\n- Fixes an issue where if used with middlewares (like Ring), or really anything that passes a `:params` key from outside of Ruuter in the request, Ruuter overwrites the `:params` key with its own parametarization. It now does a deep merge instead, with the outside parameters having priority. This means that Ruuter parameters will remain unless overwritten, and should co-exist with outside parameters nicely. [Issue #6](https://github.com/askonomm/ruuter/issues/6).\n\n- Added and fixed some tests\n\n### 1.3.3\n\n- Removed ClojureScript from dependencies to make the bundle size smaller in case you want to use Ruuter with nbb.\n\n### 1.3.2\n\n- When using wildcard parameters, the keyword returned in ´:params´ of a request was ´:name*´, but aiming for consistency with an optional parameter where we remove the question mark ´?´, the asterisk has been removed. \n\n### 1.3.1 \n\n- A small bugfix related to wildcard parameters losing the first character in the result.\n\n### 1.3.0\n\n- Fixed an issue with optional parameters not matching correctly when there were multiple optional paremeters in use.\n- Implemented wildcard parameters in the form of `:name*`, which will match everything including forward slashes.\n\n### 1.2.2\n\n- Fixed an issue where CLJS compilation would fail because of the `(:gen-class)` that is JVM-only. \n\n- Tests are now runnable for CLJS as well, via `clojure -Atest`. \n\n### 1.2.1\n\n- Fixed an issue with regex parsing. Sorry about that.\n\n### 1.2.0\n\n- Implemented optional route parameters, so now you can do paths like `/hi/:name?` in your routes, and it would match the route even if the `:name` is not present. All you have to do is add a question mark to the parameter, and that's it.\n\n- Changed Ruuter from a .clj file to a .cljc file, so it would also work with ClojureScript. Although it would probably require a more hands-on set-up than just a drop-in to an HTTP server like http-kit or ring + jetty, there is no reason that the router itself wouldn't work as it does not rely on any platform-specific code.\n\n- Ruuter also works with [Babashka](https://github.com/babashka/babashka), and I've created a \"Setting up with Babashka\" section in this README to show that.\n\n### 1.1.0\n\n- Made Ruuter server-agnostic, which means now it really is just a router and nothing else, and can thus be used with just about any HTTP server you can throw at it. It also means there are now zero dependencies!
