json-pretty-html

Transforms a JSON object into an HTML string. Allows selecting a subset of the object and highlight it with a CSS class.

Usage

var json = {
  "id": 2,
  "name": "An ice sculpture",
  "price": 12.50,
  "tags": ["cold", "ice"],
  "dimensions": {
    "length": 7.0,
    "width": 12.0,
    "height": 9.5
  },
  "warehouseLocation": {
    "latitude": -78.75,
    "longitude": 20.4
  }
};
var prettyHtml = require('json-pretty-html').default;
var html = prettyHtml(json, json.dimensions);

With a nice CSS, the result will be:

Or you can define your own styles. See below the list of CSS classes used in the generated HTML:

Always associated with the json-pretty class. json-key | Object key, excluding double quotes json-string | String value, excluding double quotes json-number | Number value json-boolean | Boolean value
