haste-server/static/application.js
zneix 509971c5ac
Switched to proper babel-minify lib
I Decided to remove static asset compression from actual code to make runtime faster and moved it to package.json script which only builds application once on installation.\nAfter this commit, after every update that changed static/application.js, you also need to run npm run-script build after git pull
