pushy

Build Status

A Clojurescript library for quick and easy HTML5 pushState.

Install

Clojars Project

Usage

Setup

You can construct a new instance by calling the pushy function.

pushy takes in two arguments:

  • dispatch fn: gets called when there is a match
  • match fn: checks if the path matches any routes defined.

Optionally, you can specify an :identity-fn which parses and returns the route based on the result of the match fn.

Event listeners

You can start the event listeners with the start! method.

This adds an event listener to all click events, which dispatches on all matched routes. Bypasses on Alt, Shift, Meta, Ctrl keys and middle clicks.

The stop! method will tear down all event listeners of the pushy instance.

Routing libraries

pushy should work with any routing library:

Secretary

(ns foo.core
  (:require [secretary.core :as secretary :include-macros true :refer-macros [defroute]]
            [pushy.core :as pushy]))

(secretary/set-config! :prefix "/")

(defroute index "/foo" []
  (.log js/console "Hi"))

(def history (pushy/pushy secretary/dispatch!
                          (fn [x] (when (secretary/locate-route x) x))))

;; Start event listeners
(pushy/start! history)

Bidi

(ns foo.core
  (:require [bidi.bidi :as bidi]
            [pushy.core :as pushy]))

(def state (atom {}))

(def app-routes
  ["/" {"foo" :foo}])

(defn set-page! [match]
  (swap! state assoc :page match))

(def history
  (pushy/pushy set-page! (partial bidi/match-route app-routes)))

(pushy/start! history)

Silk

(ns foo.core
  (:require [domkm.silk :as silk]
            [pushy.core :as pushy]))

(def state (atom {}))

(def app-routes
  (silk/routes [[:foo [["/foo"]]]]))

(defn set-page! [match]
  (swap! state assoc :page match))

(def history
  (pushy/pushy set-page! (partial silk/arrive app-routes)))

(pushy/start! history)

URL handling

By default pushy will dispatch on all relative URLs and absolute URLs that match the window's origin. This means that all external links will be bypassed.

It is possible to specify which URLs are processable to pushy by specifying a custom predicate function :processable-url? in the constructor. This function is passed a single argument which is an instance of goog.URI.

goog.history.HTML5History methods

You can set the history state manually by calling the set-token! method. This will call the dispatch fn on a successfully matched path.

Example:

(set-token! history "/foo")

(get-token history)
;; => /foo

Likewise, you can call replace-token! which will also call the dispatch fn and replace the current history state without affecting the rest of the history stack.
