New Project
We’ll use jets new to generate a new Jets project.
jets new demo --mode api
The --mode api option generates a Jets project designed for APIs.
❯ jets new demo --mode api

The project structure is lightweight for api mode. For more information about the folders, see Project Structure.
Application Config
Let’s take a look at the starter application config. It looks something like this:
config/application.rb
module Demo
class Application < Jets::Application
config.load_defaults 5.0
config.project_name = "demo"
config.mode = "api"
end
end
The project_name will be used when we deploy this project. The project that is deployed will have the environment added, IE: demo-dev.
You can override settings for each environment with the files in config/environments. Example:
config/environments/development.rb
Jets.application.configure do
config.cache_classes = false
config.eager_load = false
config.logging.event = true
end
For more settings see the Config Reference.
Next, we’ll review the generated project files.
