DB Migration
Let’s run the create the database and run the migration.
jets db:create db:migrate
Seeding Data
Let’s create some seed data to help with first. Create this file:
db/seeds.rb
2.times do |i|
i += 1
Post.find_or_create_by(title: "Post #{i}", body: "Body #{i}", published: true)
end
puts "Posts created"
Run jets db:seed
❯ jets db:seed
Posts created
Run jets runner to confirm that the records were created.
❯ jets runner 'puts Post.count'

Start Server
You can test locally with jets server.
Example:
❯ jets server
=> Booting Puma
=> Jets 5.0.0 application starting in development
=> Run `jets server --help` for more startup options
Puma starting in single mode...
* Listening on http://127.0.0.1:8888
Use Ctrl-C to stop
A puma web server allows you to test locally just like a normal rack app.
