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. - setting up rewrite rules to load assets from different locations. For example a developer could write a regular expression pattern to match all JavaScript files in particular website where he/she is working on, and load them from their local host. This way active development could be done in real time, and new features could be tested before deploying to production. This method is also useful to debug a production issues. example: if developer wants to test how the new code will affect the production website: http://www.mysite.com where all Java Script comes from: http://mysite.com/scripts/all_java_script.js file, they could write a rule that will match 'http://mysite.com/scripts/all_java_script.js' and load it from the localhost 'http://localhost/all_java_script.js' - Setting proxy rules that match different Regular expression patterns. Developers could write different matching patterns for different proxy rules. - Script injection allowing to add new CSS or Java Script to a website for testing purposes.
