Best way to combine and minify JS / CSS on Heroku
I'm using Jammit on Heroku. Works Great. You can locally build your assets and check in to heroku. use
jammit --force
the current version 0.5.1 has issues working on heroku but you can install the fixed version from git://github.com/documentcloud/jammit.git
If you are using Rails 3, specify the below in your bundler Gemfile:
gem "jammit", :git => "git://github.com/documentcloud/jammit.git"
For Rails 2.*
config.gem "jammit", :source => "git://github.com/documentcloud/jammit.git"
Good Luck.
I've found that adding a git pre–commit hook which compiles and packs assets, then adds them to the current commit comes in handy in this case.
Mine using Jammit looks something like this (in .git/hooks/pre-commit
):
jammitrake barista:brewgit add public/assets/*git add public/javascripts/*
Like this all your assets will be packed for you and you don't have to worry anymore about it.
GitHub has a good answer for this, and I'm sure you could modify Heroku's deployment scripts to integrate:
