</html>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.
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
