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
