## What it is
TanStack Bling is a framework-agnostic set of transpilation utilities and macros for TypeScript, enabling isomorphic client/server RPCs (via the server$ macro), environment isolation, islands architecture, and module splitting. It works at build time to transform code so functions can run seamlessly on the server while being called from the client.

## Use cases
- create isomorphic server functions callable from client code
- split modules and isolate environments at build time
- implement islands architecture in any framework
- call server-side logic via fetch without writing API endpoints
- share code between SSR and client bundles safely

## When to choose
- you want framework-agnostic server RPC macros in a TypeScript build
- you need env isolation or module splitting without adopting a full meta-framework
- you're already in the TanStack ecosystem and want isomorphic functions

## When to avoid
- you need a battle-tested, production-hardened RPC layer with long-term support
- your framework already provides built-in server actions or RPC utilities
- you need a mature project with active maintenance and releases
