Hoplon is a set of tools and libraries for making web applications.

Hoplon provides a compiler for web application frontend development, and includes the following libraries as dependencies to complete the stack:

• Javelin: a spreadsheet-like dataflow library for managing client state. Hoplon tightly integrates with Javelin to reactively bind DOM elements to the underlying Javelin cell graph.
• Castra: a full-featured RPC library for Clojure and ClojureScript, providing the serverside environment. (optional)

Install clj-new:

clojure -Ttools install com.github.seancorfield/clj-new '{:git/tag "v1.2.399"}' :as clj-new

And then generate a starter project with:

clojure -Tclj-new create :template hoplon :name myname/hoplon-starter-project

src/pages/index.cljs:

(page "index.html")

(ns ^{:hoplon/page "index.html"} pages.index
  (:require [hoplon.core  :as h :refer [div ul li html head title body h1 span p button text]]
            [javelin.core :as j :refer [cell cell=]]
            [hoplon.jquery]))

(defn my-list [& items]
  (div
    :class "my-list"
    (apply ul (map #(li (div :class "my-list-item" %)) items))))

(def clicks (cell 0))

(html
  (head
    (title "example page"))
  (body
    (h1 "Hello, Hoplon")

    (my-list
      (span "first thing")
      (span "second thing"))

    (p (text "You've clicked ~{clicks} times, so far."))
    (button :click #(swap! clicks inc) "click me")))

Hoplon has been thoroughly tested on desktop and mobile devices against the following browsers:

• http://hoplon.io
• Design Document (early version)
• The Wiki

• Hoplon demo applications repository
