From 5e56610fa8f4216fa3de913790e3efd50cf3a8aa Mon Sep 17 00:00:00 2001 From: Nathan Nguyen <146415969+NathanDrake2406@users.noreply.github.com> Date: Fri, 6 Mar 2026 04:57:43 +1100 Subject: [PATCH 01/42] feat: wire output: 'export' to vinext build Add runStaticExport() orchestrator that connects the existing staticExportPages/staticExportApp functions to the CLI build pipeline. When next.config has output: 'export', vinext build now: 1. Runs the Vite build 2. Starts a temporary dev server 3. Renders all static pages to out/ 4. Prints a summary Also adds 'vinext start' rejection for export builds, matching Next.js behavior (ported from test/e2e/app-dir-export/test/start.test.ts).
