Hi Fabian, No idea how to works your function. Packer seems very efficient. "make build" on frontend/application/sample generate a file sample.js of 1004kb. After using Packer on this file, the size becomes 576kb. The demo is not broken ! And after using gzip on this "Packed" file, the size becomes 193kb.
