System Documentation

What problem does it solve?

Isomorphic-by-default development means code runs in both server and client bundles by default. This skill clarifies how to separate server-only logic from client-safe operations to prevent data leaks and runtime errors.

Core Features & Use Cases

  • Server-bound APIs: creating server functions that run only on the server, with client calls triggering network requests.
  • Client/Server boundaries: isomorphic functions that switch behavior based on environment, plus ClientOnly components and hydration guards.
  • Environment safety: guidance on VITE_ prefix exposure and safe access to process.env via server boundaries.

Quick Start

Use the execution model to clearly delineate code that runs on the server from code that runs on the client during SSR and client navigation.
