FSCheckout

Problems to solve

• Generally, checkout flows have similar features like state management and step trackers so we shouldn't reinvent the wheel.
• Checkout is complicated so we don't want 10 projects with 10 different code structures to manage.
• Despite some similarities, many checkouts have unique features so we don't want an inflexible library that makes it hard to customize.

Goal

• Create a way to standardize the checkout structure.
• Make common functionalities reusable.
• Make it flexible for customization.

How

• Project checkout has to built with FSCheckout component.
• Leverage TypeScript to force a standardized code structure for:
  • how steps are structured
  • how checkout state and data are managed
  • how api request is made
  • how step progress is managed
• Each step must be separated into its own component and passed to FSCheckout as props with their name and status.
• Step Component must be StatelessComponent, and all the states have to go into the main Checkout component as a single state.
• checkoutState and checkoutActions are required to pass to FSCheckout for defining checkout state and actions
• Step progress is managed internally in FSCheckout, and reference function is provided to perform arbitrary step jump.
• step changing hook is provided to do stuff like analtyics
• A global loading view is provided to mask user interaction. It can be overridden with a custom render.
• Built in a step tracker. It's customizable with style props and can be overridden with a custom render.
