API

JSONFormatter(json [, open [, config] ])

json (Object) - required

The JSON object you want to render. It has to be an object or array. Do NOT pass raw JSON string.

open (Number)

Default: 1 This number indicates up to how many levels the rendered tree should expand. Set it to 0 to make the whole tree collapsed or set it to Infinity to expand the tree deeply

config (Object)

Default:

{
  hoverPreviewEnabled: false,
  hoverPreviewArrayCount: 100,
  hoverPreviewFieldCount: 5,
  theme: '',
  animateOpen: true,
  animateClose: true
}

Available configurations:

Hover Preview
  • hoverPreviewEnabled: enable preview on hover.
  • hoverPreviewArrayCount: number of array items to show in preview Any array larger than this number will be shown as Array[XXX] where XXX is length of the array.
  • hoverPreviewFieldCount: number of object properties to show for object preview. Any object with more properties that thin number will be truncated.
Theme
  • theme: a string that can be any of these options: ['dark']. Look at src/style.less for making new themes.
Animation
  • animateOpen: enable animation when expanding json object. True by default.
  • animateClose: enable animation when closing json object. True by default.

openAtDepth([depth])

const formatter = new Formatter({ ... });
document.body.appendChild(formatter.render());
formatter.openAtDepth(3);
depth (Number)

Default: 1 This number indicates up to how many levels the rendered tree should open. It allows use cases such as collapse all levels (with value 0) or expand all levels (with value Infinity).
