Testing for correct 'combining'

Often several JavaScript files are combined into a single one to allow the browser to load all important JavaScript methods at once with one request. This greatly accelerates the page in the HTTP-1 environment.

Leankoala can be configured to detect errors that occur when creating such a master file. 

Errors in the source code

As soon as a small error has crept into the source code, it can happen that pages are no longer displayed correctly. Reasons for this can be, for example, incorrectly placed brackets or simple syntactical errors.  

Leankoala checks all stored JavaScript files, no matter if Dev, Stage or Live and warns as soon as an error has crept in.
