Function requireAuth

requireAuth(options?: RequireAuthOptions): MiddlewareFunction
Guard that requires authentication.

Without options an unauthenticated request is answered 401 Problem Details. With signInPage, an unauthenticated browser navigation (see RequireAuthOptions.signInPage) is answered 302 to the sign-in page instead, carrying the requested path and query as returnTo — validated by safeReturnTo, which the application's own login handler should apply again before redirecting back. Every other unauthenticated request keeps the 401.
Parameters
- Optionaloptions: RequireAuthOptions
  Optional sign-in page for browser navigations
Returns MiddlewareFunction
Middleware function
Throws
When signInPage is not a same-origin absolute path
Example
```
app.router.get('/protected', { middleware: [requireAuth()], handler });
app.router.get('/account', { middleware: [requireAuth({ signInPage: '/login' })], handler });
```
