Server Actions Design

Category: Security  ·  Sub-category: zero-trust  ·  Last updated:
type:reviewtype:integration
Use when designing or reviewing Server Actions: the 'use server' directive contract, how a server-side function becomes invokable from the browser without an API route, form integration via the `action` attribute, the React 19 hooks useActionState / useFormStatus, progressive enhancement (works without JS), server-side validation and authorization as mandatory rather than optional, revalidation primitives (revalidatePath, revalidateTag, redirect), error handling and bound arguments, and the security boundary that makes Server Actions a public endpoint despite their function-like syntax. Covers Next.js App Router as the canonical implementation. Do NOT use for read-path data fetching with RSC (use server-components-design), for the broader 'use client' / 'use server' boundary semantics (use client-server-boundary), for designing externally-facing API contracts (use api-design), or for form UX patterns at the component level (use form-ux-architecture).
