Dev helper is all in one development and profiling extension for Google Chrome which has the following features:

  • Profiling webpages and drawing charts showing loading time for all assets, split by domain (including time till the first byte received)

  • Set up rewrite rules to override request and response urls, allowing developers to test without actually deploy new code. Developers could override, add or replace request and response headers to test different scenarios. For example adding 'Access-Control-Allow-Origin: *' in the response header section will resolve cross domain script blocking.

Another way to use it is to replace asset or script (JavaScript and CSS) with local copy. This way the developer could make changes and test the functionality without deployment.

1.Install the extension from chrome app store. 2. Open page’s source code, and find the script tag, that you want to re-write. 3. Copy the code, and host it locally 4. Set up rewrite rule to load this file from your local web host

Note, keep in mind that Match url is actually a regex so any regEx character should be escaped! For example if you want to match and redirect it to http://localhost?version=1
