Frameworks

NFSFU234FormValidation is dependency-free and works anywhere a real DOM exists. Pick your setup below for a from-scratch walkthrough — installation, wiring a form up, and the one gotcha specific to that environment.

Framework	Best for
Next.js	App Router or Pages Router projects — client component setup, SSR gotcha
Vite	Vite + React projects — no SSR to worry about, StrictMode double-invoke note
Create React App	CRA projects, function or class components
Expo (Web)	Expo projects targeting web — `Platform.OS` guarding required
Plain HTML	No build step, no bundler — a single script tag

All five guides end with the same next steps: the FormConfigInterface reference for multi-form setups, validateFile for file/image uploads, and the full available functions list.
