Request-specific sign-in options

Use signInOptions for defaults shared by every sign-in. Add getSignInOptions when an individual request needs to override them:

import { handleAuthRoutes, Prompt } from '@logto/express';

app.use(
  handleAuthRoutes(
    {
      ...config,
      signInOptions: { prompt: Prompt.Login },
    },
    {
      getSignInOptions: (request, flow) => {
        const prompt = request.query.prompt;

        return flow === 'signIn' && prompt === 'consent' ? { prompt: Prompt.Consent } : {};
      },
    }
  )
);

Resolver values override signInOptions. The SDK manages callback redirect fields and forces the registration screen for the sign-up route. Validate or allowlist request input before copying it into sign-in options.
