Hoplon

[]9

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)

Quickstart

Install deps-new if you haven't already:

clojure -Ttools install io.github.seancorfield/deps-new '{:git/tag "v0.5.1"}' :as new

And then generate a starter project with:

clojure -Sdeps '{:deps {io.github.hoplon/project-template {:git/tag "v0.2.0" :git/sha "5a10650"}}}' -Tnew create :template hoplon/hoplon :name your/app-name

Example

A small bit of Hoplon:

(ns view.index
  (:require [hoplon.core  :as h]
            [hoplon.goog]
            [javelin.core :as j]))

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

(def clicks (j/cell 0))

(defn hello []
  (h/div
    (h/h1 "Hello, Hoplon")
    (my-list
      (h/span "first thing")
      (h/span "second thing"))
    (h/p (h/text "You've clicked ~{clicks} times, so far."))
    (h/button :click #(swap! clicks inc) "click me")))
