READMEOverview ↓

Use when reasoning about the line at which execution context changes between a server runtime and a client runtime: what values can cross via serialization, what cannot, the directives that mark transitions ('use client', 'use server'), the difference between server-rendered HTML and a serialized component tree, the trust model that treats client input as adversarial, and the consequences of leaking server-only modules into client bundles. Do NOT use for when and where the UI is produced (use rendering-models), the HTTP wire protocol itself (use http-semantics), how to organize the frontend codebase (use frontend-architecture), or how to design the JSON shape of an API endpoint (use api-design).

Original description

Use when reasoning about the line at which execution context changes between a server runtime and a client runtime: what values can cross via serialization, what cannot, the directives that mark transitions (`'use client'`, `'use server'`), the difference between server-rendered HTML and a serialized component tree, the trust model that treats client input as adversarial, and the consequences of leaking server-only modules into client bundles. Do NOT use for when and where the UI is produced (use rendering-models), the HTTP wire protocol itself (use http-semantics), how to organize the frontend codebase (use frontend-architecture), or how to design the JSON shape of an API endpoint (use api-design).
