The original title is "React useCookie Hook: Cookies as Reactive State (2026)"

Short summary

This article introduces useCookie from @reactuses/core, a React hook that treats browser cookies as reactive component state. It explains the pitfalls of hand-rolling cookie logic—stale reads, string parsing, SSR crashes—and shows how the hook solves them with a TypeScript-first API built on js-cookie. The hook supports functional updates, default values, and full cookie attribute handling (expires, path, SameSite, secure).

• •useCookie turns document.cookie into reactive React state with cross-component sync
• •Built on js-cookie for battle-tested attribute handling (expiry, path, SameSite)
• •Setting undefined deletes the cookie; defaults are written on mount for SSR visibility
