New Features

Experimental Dynamic Components

In this release, state vars can be of rx.Component type and @rx.var computed vars can return rx.Component, allowing dynamic component structures to be created on the backend at runtime. This enables the full use of python expressions in generated components, as opposed to rx.cond and rx.foreach.

There are performance implications when using dynamic components so prefer static components where possible.

• Component as Var type by @masenf in #3732
• add basic integration test for dynamic components by @adhami3310 in #3990
• use bundled radix ui for dynamic components by @adhami3310 in #3993
• implement _evaluate in state by @adhami3310 in #4018

Run Backend with Granian server

install granian package and set REFLEX_USE_GRANIAN=1 to run with the new, experimental granian backend (instead of the default uvicorn).

• can run with granian by setting REFLEX_USE_GRANIAN var by @Lendemor in #3919
• change loglevel and fix granian on linux by @adhami3310 in #4012

REFLEX_USE_SYSTEM_NODE and REFLEX_USE_SYSTEM_BUN

If you prefer to run your own versions of node and bun, ensure they are on the PATH and set these environment variables to 1.

• add env var to enable using system node and bun by @Lendemor in #4006
