Bubble Tea is a “powerful little TUI framework” for Go with a steep learning curve. The program relies on processing messages in an event loop to maintain a responsive UI. Dumping messages to a file can be useful for debugging. Live code reload is possible for near real-time changes in your TUI. Using receiver methods on your model judiciously is crucial. Messages may not be received in the order they are sent, requiring careful handling. Building a tree of models is recommended for complex programs. Lastly, layout arithmetic is prone to errors, and developers must carefully manage dimensions for proper widget rendering.
