From de4bf6f5b281fac96e29f709b76e47d6c334dc14 Mon Sep 17 00:00:00 2001 From: Md Yunus Date: Fri, 27 Mar 2026 23:18:18 +0530 Subject: [PATCH 01/17] fix: server action redirects use soft RSC navigation instead of hard reload (#654) - Pre-render redirect target's RSC payload in app-rsc-entry.ts - Client detects RSC payload and performs soft navigation in app-browser-entry.ts - Falls back to hard redirect for external URLs or pre-render failures - Add E2E test verifying no hard navigation events on same-origin redirects This fixes the parity gap where server action redirects caused full page reloads instead of SPA-style soft navigation like Next.js does.

This fix ensures middleware headers are merged into static file responses across all three server paths. Changes: - prod-server.ts: Pass middlewareHeaders to tryServeStatic() for both afterFiles and fallback rewrites - index.ts: Call applyDeferredMwHeaders() before sending static file responses; add CONTENT_TYPES map for MIME types; use try/catch for error handling This maintains parity with the existing tryServeStatic() call which already included middleware headers.
