DRY: Reusable Templates
Lono design allows you to reuse CloudFormation templates. A key is the separation of config and template code in a structured and organized way.
Configs
Here’s an example config structure:
config/blueprints
└── demo
└── params
├── dev.env
└── prod.env
Notice how there are different dev and prod config files. This structure allows you to create different environments with the same CloudFormation template. Learn more: Layering.
Blueprints
The CloudFormation code itself lives in the blueprints folder.
app/blueprints
└── demo
Docs: Blueprints.
Summary
With this structure, it DRYs up your code by allowing you to reuse the same CloudFormation templates.
