Properties

Validates if a value has specific properties.

Installation

$ npm install validate.io-properties

For use in the browser, use browserify.

Usage

var hasProperties = require( 'validate.io-properties' );

hasProperties( obj, props )

Validates if a value has specific properties.

var obj = {'a': 0},
	props = ['a'];

var bool = hasProperties( obj, props );

Notes

• This method first validates that the input value is an object and returns false for any value types which are not JavaScript objects.
• This method does not climb the prototype chain.
• The property list should be an array.
• The method returns false as soon as an unrecognized property is found.

Examples

var obj = {
	'beep': true,
	'boop': false,
	'baz': 'foo',
	'bap': 'bar'
};

var props = [
	'beep',
	'bap'
];

console.log( hasProperties( obj, props ) );
// returns true

props.push( 'buzz' );
console.log( hasProperties( obj, props ) );
// returns false

To run the example code from the top-level application directory,

$ node ./examples/index.js

Tests

Unit

Unit tests use the Mocha test framework with Chai assertions. To run the tests, execute the following command in the top-level application directory:

$ make test

All new feature development should have corresponding unit tests to validate correct functionality.

Test Coverage

This repository uses Istanbul as its code coverage tool. To generate a test coverage report, execute the following command in the top-level application directory:

$ make test-cov

Istanbul creates a ./reports/coverage directory. To access an HTML version of the report,
