Common LiveView Form Pitfalls and Their Solutions

The content outlines three critical mistakes observed in LiveView forms: 1) Slow and laggy forms caused by scattered logic and server round-trips, 2) A brittle system where the UI cannot evolve without changing the database schema, and 3) Users being unable to submit forms even when their input is valid due to improper handling of changesets. The author emphasizes the importance of maintaining form state on the client, using embedded schemas for UI-specific needs, and always recreating changesets with submitted params to ensure that validation reflects the current state of the form. By addressing these issues, developers can create more responsive and maintainable LiveView forms.
