Module: DragonRuby::Rack::Bundle

Defined in:
lib/dragonruby/rack/bundle.rb

Overview

Puts a published HTML5 export where the app can serve it.

This is the step that used to be three shell lines, one of which was rm -rf against a path typed by hand. Replacing the directory rather than unpacking over it is not optional — a file deleted between two versions would otherwise stay behind and be served forever. So the delete has to happen, and the only useful thing to do about it is to refuse to delete anything that is not already a bundle.

Class Method Details

.install(zip, into, force: false) ⇒ Object

Unpacks zip into into, replacing whatever bundle is there.

Refuses when into exists but holds no index.html: that is either the wrong path or something that is not a bundle, and both are worth an error rather than a deletion. Pass force: true to say you meant it.
