In this video, Erik Rasmussen explains how state machines can be used to improve the user experience of a web application. He demonstrates how state machines can be used to pause and reload a web page, and how form data can be used to pass events between states. This video is helpful for those who want to learn how to use state machines to improve the efficiency of their code.

  • 00:00:00 State machines are a visual way of coding backend logic, used in particular on the edge. In order to use state machines on the front end, a library like xdate must be used. Async interpret takes an input of a machine definition, a timeout, and an event, and returns a promise that will be resolved once the machine transitions to a pause state or resolves an event.
  • 00:05:00 The video discusses how Erik Rasmussen created a state machine for use in his cart checkout project, using loaders and actions to achieve consistency and reliability across routes. If a route's state matches the state in a cookie, the machine is already in the right place and no further action is necessary. If the route's state doesn't match the state in the cookie, the machine is started up and redirected to the correct state, and the state is serialized and saved in a cookie.
  • 00:10:00 In this video, Erik Rasmussen explains how state machines work and how they are used in e-commerce applications. He shows how to create a state machine for an e-commerce application, and how to use it to manage the flow of users through the various stages of the checkout process.
  • 00:15:00 In this video, Erik Rasmussen explains how state machines can be used to improve the user experience of a web application. He demonstrates how state machines can be used to pause and reload a web page, and how form data can be used to pass events between states.
  • 00:20:00 This video by Erik Rasmussen covers the use of state machines on the edge, which allows for more efficient and less redundant code. This is especially helpful for backend logic, as state machines can be used to send data without needing frontend JavaScript.
