We&#x27;ve been using Closure to minify our code for years. It&#x27;s extremely slow (I think it takes a minute or so on our codebase), so we only do it for deploys.<p>It produces smaller code than minifiers such as Uglify, even though we&#x27;re not using its coding conventions (Closure is designed to optimize code written in a certain way that allows it to eliminate dead code paths).
