The Host Builder

We have introduced the Host Builder (currently in active developement) some months ago and its already been available behind a flag FUNC_ENABLE_HOST_BUILDER which needs to be set to truthy value in order to use it.

Why use it?

It’s way faster to build your Functions!. Func will package your Functions directory as an archive in a specific way into an image ready to be ‘run’ locally on your machine, within seconds!
