<!-- 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">

</head>
<body>
<div id="jsoneditor" style="width: 400px; height: 400px;"></div>
<script>
// create the editor
const container = document.getElementById("jsoneditor")
const options = {}
const editor = new JSONEditor(container, options)
// set json
const initialJson = {
"Array": [1, 2, 3],
"Boolean": true,
"Null": null,
"Number": 123,
"Object": {"a": "b", "c": "d"},
"String": "Hello World"
}
editor.set(initialJson)
// get json
const updatedJson = editor.get()
</script>
</body>
</html>
Build
The code of the JSON Editor is located in the folder ./src. To build
jsoneditor:
-
Install dependencies:
npm install -
Build JSON Editor:
npm run buildThis 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 startThis will update
./jsoneditor.jsand./jsoneditor.cssin the dist folder on every change, but it will NOT update the minified versions as that's an expensive operation.
Test
Run unit tests:
npm test
Run code linting (JavaScript Standard Style):
npm run lint
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 one third 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
