Formatters

Some formatters are included that let you convert a JSON delta into other formats, you can see some of these used in the Live Demo

Html

add build/formatters.js and src/formatters/html.css to your page, and:

var delta = jsondiffpatch.diff(left, right);
// left is optional, if specified unchanged values will be visible too
document.getElementBy('the-diff').innerHTML =
  jsondiffpatch.formatters.html.format(delta, left);

// Also you can dinamically show/hide unchanged values
jsondiffpatch.formatters.html.showUnchanged();
jsondiffpatch.formatters.html.hideUnchanged();
// these will also adjust array move arrows (SVG), which is useful if something alters the html layout

Html can be generated sever-side the same way, just remember to include (or embed) /src/formatters/html.css when rendering.

Annotated JSON

This will render the original JSON delta in html, with annotations aside explaining the meaning of each part. This attempts to make the JSON delta format self-explained.

add build/formatters.js and src/formatters/annotated.css to your page, and:

var delta = jsondiffpatch.diff(left, right);
document.getElementBy('the-diff').innerHTML =
  jsondiffpatch.formatters.annotated.format(delta);

Html can be generated sever-side the same way, just remember to include (or embed) /src/formatters/annotated.css when rendering.

Console

Node.js colored output (thanks to chalk!). It's used by the CLI:

but you can use it programmatically too:

var delta = jsondiffpatch.diff(left, right);
var output = jsondiffpatch.formatters.console.format(delta);
console.log(output);

// or simply
jsondiffpatch.console.log(delta);

JSON PATCH (RFC 6902)

var delta = jsondiffpatch.diff(left, right);
var output = jsondiffpatch.formatters.jsonpatch.format(delta);
console.log(output);

Don't use with textDiff as it isn't suppported

Create one

Of course, first step to create a formatters is understanding the delta format.

To simplify the creation of new formatters, you can base yours in the BaseFormatter included. All the builtin formatters do, check the formatters folder to get started.
