Overview

Checkout provides a simple interface to perform a single step in a checkout process.

## Processing a step

If we wanted to process the delivery step of an order we would do something like this:

“‘ ruby order = Order.find(1)

delivery_address = { name: ‘Luke Morton’,

address_1: '21 Cool St',
locality: 'London',
postal_code: 'N1 1PQ',
country: 'GB' }

MarketTown::Checkout.process_step(step: :delivery,

dependencies: AppContainer.new,
state: { order: order,
         delivery_address: delivery_address,
         delivery_method: :next_day })

“‘

To find out more about ‘AppContainer` please see Dependencies.

## Available steps

- {CartStep} – Handles the initialisation of the checkout process
- {AddressStep} – Handles the taking of billing and delivery addresses
- {DeliveryStep} – Handles the choosing of delivery method
- {CompleteStep} – Handles completion of order
