Simple Node.js JSON Schema dereferencer

Package Exports

  • json-schema-deref-sync

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (json-schema-deref-sync) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

json-schema-deref-sync

Dereference JSON pointers in a JSON schemas with their true resolved values. Basically a lighter, synchronous version of json-schema-deref but omits web references and custom loaders.

Installation

npm install json-schema-deref-sync

Overview

Let's say you have the following JSON Schema:

{
  "description": "Just some JSON schema.",
  "title": "Basic Widget",
  "type": "object",
  "definitions": {
    "id": {
      "description": "unique identifier",
      "type": "string",
      "minLength": 1,
      "readOnly": true
    }
  },
  "properties": {
    "id": {
      "$ref": "#/definitions/id"
    },
    "foo": {
      "$ref": "http://www.mysite.com/myschema.json#/definitions/foo"
    },
    "bar": {
      "$ref": "bar.json"
    }
  }
}

Sometimes you just want that schema to be fully expanded, with $ref's being their (true) resolved values:

{
  "description": "Just some JSON schema.",
  "title": "Basic Widget",
  "type": "object",
  "definitions": {
    "id": {
      "description": "unique identifier",
      "type": "string",
      "minLength": 1,
      "readOnly": true
    }
  },
  "properties": {
    "id": {
      "description": "unique identifier",
      "type": "string",
      "minLength": 1,
      "readOnly": true
    },
    "foo": {
      "description": "foo property",
      "readOnly": true,
      "type": "number"
    },
    "bar": {
      "description": "bar property",
      "type": "boolean"
    }
  }
}

This utility lets you do that:

var deref = require('json-schema-deref-sync');
var myschema = require('schema.json');

var fullSchema = deref(myschema);
