validator.js-asserts

A set of extra asserts for validator.js.

Status

Installation

Install the package via npm:

$ npm install --save validator.js-asserts

Peer dependencies

Some asserts require manually installing some peer dependencies. Failing to do so will result in runtime errors, as packages are required dynamically.

Peer dependencies are not listed on package.json because npm 2 considers them mandatory peer dependencies and, therefore, always installs them, while npm 3 follows a more consensual approach of optional peer dependencies, not installing them by default but generating warning and confusing error messages instead.

You should pin these package's peer dependencies to the ranges listed on the optionalPeerDependencies key of this package's manifest.

Usage

The following is an example for the extra ip assert:

const Validator = require('validator.js').Validator;
const is = require('validator.js').Assert.extend(require('validator.js-asserts'));
const validator = new Validator();

// Validate ip `1.3.3.7`.
let violation = validator.validate('1.3.3.7', is.ip());

if (true === violation) {
  console.log('"1.3.3.7" is a valid IP'); // => "1.3.3.7" is a valid IP
}

// Validate ip `foo`.
violation = validator.validate('foo', is.ip());

if (true !== violation) {
  console.log('"foo" is not a valid IP. Violation:', violation[0].show());
  // => "foo" is not a valid IP. Violation: { assert: 'Ip', value: 'foo' }
}

// Make the validation nullable.
violation = validator.validate(null, is.nullOr(is.ip()));

if (true === violation) {
  console.log('null is null or a valid IP'); // => null is null or a valid IP
}
