Question

Any ideas on how to use Google Closure Compiler to combine multiple JavaScript files w/o any optimizations? Specifically, we want to use Closure to deploy two versions of our combined site JavaScript: release and debug. For release, we are using --compilation_level SIMPLE_OPTIMIZATIONS --manage_closure_dependencies which is working as intended. However, for debug, we would like our JavaScript to be combined intact/unmodified for easier debugging. It seems the minimum level of optimization is WHITESPACE_ONLY, any ideas would be appreciated.

Answer 1

Turns out there’s an option to format the processed JavaScript file using the --formatting PRETTY_PRINT. The option indents/formats (with whitespace) the output JavaScript file, such that the JavaScript is easily debuggable.

Wish the documentation is a little more detailed/complete 🙂
