json-html

Generates a DOM node with a human representation of the JSON/EDN encoded data. Based on the json.human.js library.

Installation

The library provides support for Clojure/Script.

Leiningen

Usage

(use 'json-html.core)

(edn->html {:foo [1 2 3] :bar "baz"})

bar	baz
foo	0 1 1 2 2 3

(json->html "{\"foo\": [1, 2, 3], \"bar\": \"baz\"}")

bar	baz
foo	0 1 1 2 2 3

The ClojureScript version has additional functions called edn->hiccup and json->hiccup, these can be used to generate Hiccup forms for use with other libraries such as Reagent.

A default CSS is provided in resources/json.human.css and can be included as follows:

(ns foo
  (:use json-html.core hiccup.page))

(spit "formatted.html"
     (html5
      [:head [:style (-> "json.human.css" clojure.java.io/resource slurp)]]
      (edn->html [:foo "bar" :baz [1 2 3]])))

Custom data types and render functions

To render data types that are not covered but the library (i.e. cljs.core/UUID) or redefine how already covered data types are rendered, extend the json-html.core/IRenderHTML protocol for your type. For example, to render UUIDs in the same way you would render its backing string, add this snippet in your code:

(extend-protocol json-html.core/Render
  cljs.core/UUID
  (render [u]
    [:span.jh-type-string (str u)]))
