assert-plus

This library is a thin wrapper over the Node built-in assert module, providing two main enhancements:

1. the ability to disable assertions with the environment variable NODE_NDEBUG

2. some API wrappers for argument testing; e.g., assert.string(myArg, 'myArg'). As a simple example:

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, {});
}

See CONTRIBUTING.md for details on how to submit changes.

API

All methods that aren't part of node's core assert API are simply assumed to take an argument, and then a string 'name' that's not a message; AssertionError will be thrown if the assertion fails with a message like:

AssertionError: foo (string) is required
at test (/home/mark/work/foo/foo.js:3:9)
at Object.<anonymous> (/home/mark/work/foo/foo.js:15:1)
at Module._compile (module.js:446:26)
at Object..js (module.js:464:10)
at Module.load (module.js:353:31)
at Function._load (module.js:311:12)
at Array.0 (module.js:484:10)
at EventEmitter._tickCallback (node.js:190:38)

from:

function test(foo) {
    assert.string(foo, 'foo');
}

There you go. You can check that arrays are of a homogeneous type with Arrayof$Type:

function test(foo) {
    assert.arrayOfString(foo, 'foo');
}

You can assert IFF an argument is not undefined (i.e., an optional arg):

assert.optionalString(foo, 'foo');

Lastly, you can opt-out of assertion checking altogether by setting the environment variable NODE_NDEBUG=1. This is pseudo-useful if you have lots of assertions, and don't want to pay typeof () taxes to v8 in production. Be advised: The standard functions re-exported from assert are also disabled in assert-plus if NDEBUG is specified. Using them directly from the assert module avoids this behavior.
