88: Phoenix Debug Toolbar and LiveView Forms with Michael Crumm

We talk with Michael Crumm, the primary author of the Phoenix Live Dashboard, about a new project of his. He is working on a development toolbar that is rendered on your pages and helps profile performance, expose route info, show crash info and more. It’s called PhoenixProfiler and it ties into Telemetry events for data. While still early, it can be a great tool for teams. We also talk about another goal of his, to improve working with forms in LiveView!
