## 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
```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 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](http://browserify.org/) or [webpack](http://webpack.github.io/). 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](https://github.com/mishoo/UglifyJS2):
uglifyjs ./jsoneditor.custom.js -o ./jsoneditor.custom.min.js -m -c
