To keep the Lambda zip file size down, you might want to avoid packaging up large folders. You can do this with the .jetsignore file. Example:



This tells Jets not to package up some/large/folder and vendor/bundle.


There’s also a .jetskeep file concept. The default values for this is:


This file tells Jets to keep these files regardless of what’s configured with .jetsignore. So the .jetskeep has higher precedence than .jetsignore.

Note: If you create a .jetskeep file, it will override the defaults entirely.
