deb.js

~1.5K minimalistic JavaScript library for debugging in the browser

• works on functional level
• groups your console.log statements and place them in a proper context
• displays stack traces, passed arguments and execution time

Usage

Add deb.min.js at the top of your page. Before every other script file.

<script src="deb.min.js"></script>

Add .deb() After the definition if your functions.

var calculateSomething = function(cb) {
	// ...
}.deb();

Open your console. You should see something like that:

Use .debc() to collapse the output.

Deb.js as Chrome extension

Deb.js in Google Web Store

There is an extension for Chrome that injects deb.min.js in your page. All you have to do is to open this url and add debjs somewhere in your URL. For example:

http://mysite.com/ <-- Deb.js is disabled
http://mysite.com?data=yes&prop=20&debjs <-- Deb.js is enabled

Once you do that the extension will inject the file before your page's content and you will be able to use .deb() or debc() methods.

Notice that if Deb.js is enabled you will see a small badge ON applied.
