CommonJS Utils is a collection of general purpose CommonJS-compliant modules. These modules can be used on Narwhal, Node, and other CommonJS platforms. The modules include:
- json-schema.js – This is a JSON Schema validator module. It can be used to validate data structures using JSON schema definitions. For example:
var validate = require("json-schema").validate;
var data = {name: "Test"};
var schema = {
properties: {
name: {type: "string"},
age: {type: "number"}
}
};
var validation = validate(data, schema);
validation.valid -> false
validation.errors -> indicates that age was not provided
data.age = 30;
var validation = validate(data, schema);
validation.valid -> true
This module also supports using standard native constructors as type definitions. The schema above could be written
more briefly:var schema = {
properties: {
name: String,
age: Number
}
};
