injectr #

_Finally, a solution to node.js dependency injection_

Install it ##

npm install injectr. Boom.

Use it ##

var injectr = require('injectr');
var myScript = injectr('../lib/myScript.js', {
fs : mockFs,
crypto : mockCrypto
});

Now when you require('fs') or require('crypto') in myScript.js, what you
get is mockFs or mockCrypto.

Treat injectr like require for your tests, with a second argument to pass
in your mocks.

Paths are now relative to the current file, just like require. Please update
your tests if you are upgrading from v0.4 or below.

injectr gives you access to the context of the injectr'd file via
an optional third argument. Provide an object, and injectr will modify it
as necessary and use that as the context.

var myScript = injectr('../lib/myScript.js', {}, {
Date : mockDate,
setTimeout : mockSetTimeout
});

As of version 0.4, injectr doesn't create a full node.js context for you to
use. Instead, it isolates your script in its own sandbox, allowing you to
include mocks of only the bits that your script needs.

$3

injectr compiles any *.coffee files for you, so you can test your
CoffeeScript too. The default settings can be changed by overwriting the
injectr.onload function. It takes the filename and file contents as
arguments, and returns the compiled script.
