Improving User Experience in Form Handling with Elixir's LiveView

Andrew Ek's talk at GigCityElixir23, titled 'Better Forms with LiveView', delves into improving the way forms are handled in LiveView to create a high-quality user experience. The discussion emphasizes using features like semantic HTML inputs, handling form disconnects gracefully, validating form inputs in real-time, and showing errors next to respective fields. Andrew provides insights into best practices for form interfaces, such as placing error messages near the corresponding inputs, ensuring forms align with the user's conception of the domain, and using semantic HTML for accessibility. He highlights new LiveView features that keep track of input changes and only display validation errors at appropriate times. Although Andrew notes limitations such as aggressive validations and the developer ergonomics not being ideal, he suggests these areas can improve with time. He also discusses weighing development speed against the level of UI polish needed, and how business or personal values shape these decisions.
