## What it is
nuqs is a type-safe search params state manager for React frameworks, offering a useState-like API that stores state in the URL query string. It supports Next.js (app and pages routers), plain React SPAs, Remix, React Router, and TanStack Router via adapters, with built-in parsers and serializers for common state types.

## Use cases
- sync react component state with url query string
- manage filters and pagination in url params in next.js
- type-safe search params in react server components
- shareable urls with encoded app state
- parse and serialize query string values like dates and integers
- manage multiple related querystring keys in react
- use browser back button to navigate state changes

## When to choose
- you build React apps (especially Next.js) and want URL-driven, shareable state
- you need end-to-end type safety between server and client components for search params
- you want a tiny (5.9kB) hook-based alternative to manual query string handling
- you need built-in parsers for common types and history control (replace vs append)

## When to avoid
- your project is not React-based (Vue, Svelte, Angular)
- you only need to read query params once on page load without reactive updates
- you need complex global state management beyond URL-representable state
