server / RPC

Start server boundary

Place SSR, Server Functions, and external Server Routes at the correct execution boundary.

Engineering doc / recipeCreate a server-only functionUse createServerFn to define a same-origin, type-safe server RPC.

Lesson 08Put external endpoints in a Server RouteSeparate application RPC from public HTTP endpoints and use a native Response to express status, body, and cache policy.

server route / HTTP

Engineering doc / recipeCreate an externally callable Server RouteBuild a native HTTP endpoint for third-party callers with explicit status, caching, and safe responses.

Lesson 11Compose request boundaries with MiddlewareSeparate request middleware from Server Function middleware and compose logging, context, and security checks with next().

11

middleware / next

Server request pipeline

Choose the correct middleware scope for requests and Server Functions, then advance the chain explicitly.

Engineering doc / contractEstablish a Start Middleware chainDefine request and function scopes, compose context through next(), and preserve authentication and CSRF boundaries.
