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 listed on package.json under peerDependencies. The peerDependenciesMeta key identifies which peer dependencies are optional. NPM will not automatically install optional peer dependencies. See the NPM documentation for more information.

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
}
