New Project
We’ll use jets new to generate a new Jets project.
jets new demo --mode job
The --mode job option generates a Jets project designed for jobs.
❯ jets new demo --mode job
create .env
create .gitignore
create Gemfile
create README.md
create Rakefile
create app/jobs/application_job.rb
create config/application.rb
create config/environments/development.rb
create config/environments/production.rb
create config/environments/test.rb
The project structure is nice and lightweight for job 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 = "job"
config.prewarm.enable = false
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. Since this app is for jobs, prewarming is set to false.
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 = false
end
For more settings see the Config Reference.
Next, we’ll explore project files and write some code.
