Boilerplate

A full-stack boilerplate using Next.js App Router, demonstrating how to detect and alert users about unsaved changes in form pages. This setup prevents accidental data loss by prompting users before navigating away from edit or create forms with modified, unsaved input.

Features

• Next.js App Router for modern frontend development.
• Unsaved changes detection in create and edit forms.
• Navigation blocker to prevent route changes when there are unsaved fields.
• Custom alert modal or native browser prompt support.
• Works with controlled forms (React Hook Form, useState, or custom implementations).
• Reusable hook or middleware-style logic for form state monitoring.
• TypeScript support for type-safe development.

Use Case

Ideal for applications that include data entry workflows, such as admin panels, CRMs, SaaS platforms, or any app where users can create or edit data. This boilerplate improves UX by reducing the risk of unintentional data loss, ensuring users are always warned before navigating away from unsaved forms. 🚀
