 Now that we have data fetching pretty well sorted, we're exploring the other direction: sending data from the client to the server, so that you can execute database mutations and implement forms. We're doing this by letting you pass Server Action functions across the server/client boundary, which the client can then call, providing seamless RPC. Server Actions also give you progressively enhanced forms before JavaScript loads.

There's a clear separation for features provided by the RSC spec and implementation. React Server Components is meant as a spec for components that work across compatible React frameworks.
 
 We generally recommend using an existing framework, but if you need to build your own custom framework, it is possible. Building your own RSC-compatible framework is not as easy as we'd like it to be, mainly due to the deep bundler integration needed. The current generation of bundlers are great for use on the client, but they weren't designed with first-class support for splitting a single module graph between the server and the client. This is why we're now partnering directly with bundler developers to get the primitives for RSC built-in.

If your library targets apps not yet on React 19, specify a minimum `target` and add `react-compiler-runtime` as a direct dependency. The runtime package will use the correct implementation of APIs depending on the application's version, and polyfill the missing APIs if necessary.
