Difference between rake assets:precompile and rake assets:clobber

Question

Can anyone please tell me the difference between rake assets:precompile and rake assets:clobber. really its a great confusion.

Answer 1

You can precompile the assets in app/assets using rake assets:precompile, and remove older compiled assets using rake assets:clean. The rake assets:clean task allows for rolling deploys that may still be linking to an old asset while the new assets are being built. If you want to clear public/assets completely, you can use rake assets:clobber.

rake assets:clean # Remove old compiled assets

rake assets:clobber # Remove compiled assets

rake assets:precompile # Compile all the assets named in config.assets.precompile

Answer 2

Note: rake assets:clobber also removes the assets directory completely.

To get the info on any rake tasks try this :

rake --describe | grep assets

This returns all the answers.

rake assets:clean[keep]
   Remove old compiled assets
rake assets:clobber
   Remove compiled assets
rake assets:environment
rake assets:precompile
  Compile all the assets named in config.assets.precompile

Answer 3

the command rake assets:clobber removes/deletes all compiled assets. Whilst the command rake assets:precompile creates the compiled assets listed on parameter config.assets.precompile.

Please have a read on Rake's documentation for further information on it
