Retaining line numbers with the Rails asset pipeline

By default the Rails 3 asset pipeline uses the Uglifier gem to optimize and minify your Javascript. One of its many optimisations is to remove all whitespace, turning your Javascript into one very long line of code.

Whist removing all the newlines helps to reduce the file size, it has the disadvantage of making your Javascript harder to debug. If you've tried to track down Javascript errors in minified Javascript files you'll know the lack of whitespace does make life harder.

Luckily there is a simple solution: to configure Uglifier to add newlines back into the code after it performs its optimisations. And if you're serving your files correctly gzip'd, the newlines add only a small increase to the final file size.

You can configure Uglifier to add the newlines by setting the following in your Rails 3 config/production.rb file:

Howto:

Run an insert statement to YQL, storing your API Key with a use statement linking to this gist.

insert into yql.storage.admin (value) values ("
use 'https://raw.github.com/gist/5ceb77a28686513f16a7/cb17fcb095847f320426fb0fc5261d47cf62b0d8/postmark.xml' as postmark;
set api_key='YOUR KEY HERE' on postmark;
")

	Don't go to Fishermans Wharf. Drive out to Santa Cruz, Muir Woods, Point Reyes, Napa and Sonoma.

	If you want to spend 500USD on a meal then get a ticket to Saison Chef's Counter. Highly recommended.

	Walk around Embarcadero. Check out Golden Gate Park. Do you like to ride bicycles?

	Head to Umi and Tataki South for sushi. Head to Chez Maman and Papito. Piccino. Plow for brunch, be sure to have the potatoes.

	Don't do brunch on the weekend though. You'll always have to wait. Weekdays are best.
