Frequently Asked Questions

What does assert-plus do?

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.

How do you use assert-plus?

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.

Where are the assert-plus docs?

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.
