Documentation

Install

with npm (recommended):

npm install jsoneditor

Note that to use JSONEditor in Internet Explorer 11, it is necessary to load a polyfill for Promise in your application.

Use

<!DOCTYPE HTML><html><head><!-- when using the mode "code", it's important to specify charset utf-8 --><metahttp-equiv="Content-Type" content="text/html;charset=utf-8"><linkhref="jsoneditor/dist/jsoneditor.min.css" rel="stylesheet" type="text/css"><scriptsrc="jsoneditor/dist/jsoneditor.min.js"></script></head><body><divid="jsoneditor" style="width: 400px; height: 400px;"></div><script>// create the editorconstcontainer=document.getElementById("jsoneditor")constoptions={}consteditor=newJSONEditor(container,options)// set jsonconstinitialJson={"Array": [1,2,3],"Boolean": true,"Null": null,"Number": 123,"Object": {"a": "b","c": "d"},"String": "Hello World"}editor.set(initialJson)// get jsonconstupdatedJson=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 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 start

    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.

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
