JSON Schema Defaults

Generate JSON object from default values in JSON Schema

Works both in node and browser.

Installation

• npm

  npm install json-schema-defaults
  

• bower

  bower install json-schema-defaults
  

• manual

  Download lib/defaults.js

Usage

• CommonJS (node.js)

  var defaults = require('json-schema-defaults');
  defaults({ ... });
  

• RequireJS

  // in require.js config
  paths: {
    'defaults': './path/to/lib/defaults.js'
  }
  
  // in a file
  define(['defaults'], function(defaults) {
    defaults({ ... });
  });
  

• standalone

  window.jsonSchemaDefaults({ ... });
  

  If the standalone version causes any conflict with existing jsonSchemaDefaults global variable, you can return back the original variable:

  var defaults = window.jsonSchemaDefaults.noConflict();
  // `window.jsonSchemaDefaults` now points to the original variable
  // `defaults` points to this script
  defaults({ ... });
  

• CLI

  If installed globally:

  json-schema-defaults schema.json
  

  If locally:

  ./node_modules/.bin/json-schema-defaults schema.json
  

  Custom indentation (defaults to 2):

  json-schema-defaults --indent 4 schema.json
  

  Write into a file:

  json-schema-defaults schema.json > defaults.json
  

Documentation

Call defaults with JSON Schema. The default values will be extracted as a JSON.

var json = defaults({
  "title": "Album Options",
  "type": "object",
  "properties": {
    "sort": {
      "type": "string",
      "default": "id"
    },
    "per_page": {
      "default": 30,
      "type": "integer"
    }
  }
});

// would return
{
  sort: 'id',
  per_page: 30
}

For more examples, see the tests.
