Type-Safe Next.js Server Actions

next-safe-action is a library designed for Next.js projects to create type-safe and validated Server Actions. It leverages modern Next.js, React, and TypeScript features to ensure end-to-end type safety from client-side component calls to server-side action execution. The current stable version is 8.5.2, with minor and patch releases occurring frequently to refine types, add features, and improve developer experience. Key differentiators include robust input/output validation, a flexible middleware system for authorization or logging, advanced server error handling, and support for optimistic updates, making it a powerful tool for building reliable and predictable data mutations in Next.js applications.
