assert-plus 0.1.0

Assert-plus is a lightweight library offering enhanced features over Node's assert module. The module brings two extended functionalities, the environment variable NODE_NDEBUG that allows users to disable assertions, and API wrappers such as assert.string(myArg, 'myArg') that are designed for argument testing, improving the validation process within your code.

Utilizing assert-plus involves straightforward means and requires minimal effort. The first step is to install the package through npm using npm install assert-plus. You can use it within your JavaScript function like so:

    var assert = require('assert-plus');

    function fooAccount(options, callback) {
        assert.object(options, 'options');
        assert.number(options.id, 'options.id');
        assert.bool(options.isManager, 'options.isManager');
        assert.string(options.name, 'options.name');
        assert.arrayOfString(options.email, 'options.email');
        assert.func(callback, 'callback');

        // Do stuff
        callback(null, {});
    }

In this code, we're utilizing assert-plus to ensure that the correct types are passed to a function. If the wrong type is passed, an AssertionError will be thrown.

The comprehensive and updated documentation for assert-plus is hosted within the Readme file on the GitHub repository at https://github.com/mcavage/node-assert-plus. Here you'll find details about the API, installation guides, and code usage examples for each category of assertions provided by this powerful module.
