There is a directive available for using JSONEditor in Angular.js:


    <!-- when using the mode "code", it's important to specify charset utf-8 -->
    <meta http-equiv="Content-Type" content="text/html;charset=utf-8">

    <link href="jsoneditor/dist/jsoneditor.min.css" rel="stylesheet" type="text/css">
    <script src="jsoneditor/dist/jsoneditor.min.js"></script>
    <div id="jsoneditor" style="width: 400px; height: 400px;"></div>

        // create the editor
        var container = document.getElementById("jsoneditor");
        var options = {};
        var editor = new JSONEditor(container, options);

        // set json
        var json = {
            "Array": [1, 2, 3],
            "Boolean": true,
            "Null": null,
            "Number": 123,
            "Object": {"a": "b", "c": "d"},
            "String": "Hello World"

        // get json
        var json = editor.get();


The code of the JSON Editor is located in the folder ./src. To build jsoneditor:
  • Install dependencies:
    npm install
  • Build JSON Editor:
    npm run build
    This will generate the files ./jsoneditor.js, ./jsoneditor.css, and
    minified versions in the dist of the project.
  • To automatically build when a source file has changed:
    npm run watch
    This will update ./jsoneditor.js and ./jsoneditor.css in the dist folder on every change, but it will NOT update the minified versions as that's an expensive operation.

Custom builds

The source code of JSONEditor consists of CommonJS modules. JSONEditor can be bundled in a customized way using a module bundler like browserify or webpack. First, install all dependencies of jsoneditor:
npm install
To create a custom bundle of the source code using browserify:
browserify ./index.js -o ./jsoneditor.custom.js -s JSONEditor
The Ace editor, used in mode code, accounts for about 75% of the total size of the library. To exclude the Ace editor from the bundle:
browserify ./index.js -o ./jsoneditor.custom.js -s JSONEditor -x brace -x brace/mode/json -x brace/ext/searchbox
To minify the generated bundle, use uglifyjs:
uglifyjs ./jsoneditor.custom.js -o ./jsoneditor.custom.min.js -m -c
