Javascript minimizer and profiler

Robert

Hi,

I'm interested in two applications for javascript. A profiler and a
minimizer. I found several, but I am hoping to hear with which
applications some of you guys have a good experience. I prefer open
source projects.

The minimizer should make the javascript small. Not just removing
white-space and comments, but also make object names very small. This
will probably obfuscate things, but the goal does not have to be
obfuscation.

The profiler should show all functions, how much time was spent inside
it (percentage and absolute time), with and without calls to other
methods, etc. Just like another "real language" profiler.

Any suggestions?

Robert.

I haven't tried this tool, but I use their code coverage validator with much
success.

For profiling you can use Venkman, which is a Firefox extension.

JavaScript Performance Validator. Commercial software tool, currently in
beta.

Just like other profilers - in fact it has the same UI (barring
differences for languages) as the C++, Delphi, Visual Basic, Java,
Python, Ruby, Lua, Perl and PHP profilers with the same name (so if you
are writing an AJAX app using Ruby on Rails the profiler for both Ruby
on Rails and JavaScript would look and behave identically if you used
the JavaScript Performance Validator and Ruby Performance Validator).
The UI looks and behaves the same, the underlying "engine" is different,
tailored to the language in use.

Real time callstack viewing, statistics, analysis, relations, call graph
and call tree and line timing support. XML and HTML data export.

Works with Firefox 1.0, 1.5 and Flock 0.7. Windows only at the moment.
