Why protected routes
Goal: Protect pages that need a signed-in user.
- Track auth state
- Guard routes
- Remember intended path
Core concepts
- Auth store: user or null
- Guard: if no user → go login
- Post-login: navigate to saved target
Auth store setup
Create a tiny auth context with login/logout and a simple router state.
<div id="root"></div>Guard + remember target
A ProtectedRoute checks auth. If missing, it shows a login view and stores the target route.
<div id="root"></div>Role-based guard
Add a role check: show 403 message if user lacks permission.
<div id="root"></div>Tips & pitfalls
- Never render protected content before auth is known
- Store intended route; go there after login
- Show clear 401/403 messages
Protected route behavior check
Recap
Recap: Keep an auth store, guard protected routes, save the intended path, and add simple role checks for admin-only areas.
