A Rack profiler for web application.

Installation

Add this line to your application's Gemfile:

gem "rack-webprofiler"

And then execute:

Or install it yourself as:

Usage

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

You can use bin/start-dev to run the example and test the library.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
