captureCalls.js

Demo

Usage

There are two ways to use captureCalls.js: a Chrome extension or a standalone script.

Chrome extension

Once installed, it runs on all web sites and defines captureCalls function globally, so it can be used not only in DevTools console but in all JavaScripts as well.

Standalone script

Download captureCalls.js and include it into your web page <script src="captureCalls.js"></script>.

It’s generally a good idea to include captureCalls.js only for a developer environment and keep it out of production.

Options

captureCalls.stacktrace
true: include stack traces in the output

captureCalls.logFileNames
true: show URLs with line numbers, e.g. http://nv.github.io/captureCalls.js/demo/demo.js:7

captureCalls.logDetails
false: show an object with details, e.g. {this: window, function: function() {[native]}}

TODO

• Write on how captureCalls is superior to Chrome DevTools monitor function.
