Description

Tired of Rails frontends that feel brittle and messy? Bring back the joy with Phlex. In this course, you'll learn how to:

Build ambitious frontends. Snap together complex UIs without getting lost in partials, helpers, & views.
Work with existing Rails apps. Integrate Phlex components at your own pace without rewriting everything.
Level up your architecture. Create self-permitting forms, stateful views, and component-only apps that are easier to test, organize, & scale.

Whether you're leading a team or building your first app, you'll learn how to ship frontends that feel great to use and even better to build.
