In the previous post: Jets Mega Mode: Run Rails on AWS Lambda, I covered how to get Rails running on AWS Lambda with Jets. In this video tutorial, I show you how to use the --submodule option for the same command we used to set things up previously: jets import:rails. Example:

jets import:rails --submodule

Importing the Rails application as a submodule allows you to keep the Rails project in a separate repo. This allows you to manage the Rails project with a separate history and sync it with a Jets project when you want to. This is a useful setup if you are testing Jets Mega Mode Rails Support for an extended period of time.

Since git submodules take a little bit of getting used to, Jets even generates a git submodules cheatsheet as part of the jets import:rails command. Having the cheatsheet around is handy as git submodule commands are not as commonly used.
