json-schema-from-path

A utility to get the sub-schema from a JSON-schema from the path in an object

Supports schemas that use:

• properties (type object)
• additionalProperties (type object)
• patternProperties (type object)
• items (type array)
• paths that use either / or . as separators

var getSchemaFromPath = require("json-schema-from-path");

var someSchema = {
	properties: {
		foo: {
			properties: {
				bar: {
					type: "string"
				}
			}
		}
	}
};

var mypath = "foo/bar";

var theSchema = getSchemaFromPath(someSchema, path);

theSchema === someSchema.properties.foo.properties.bar

If a schema object doesn't exist for the given path, null is returned.
