Changes

Adds astro/runtime/client/dev-toolbar/entrypoint.js to the client environment's optimizeDeps.include. That's all

Testing

Reproduced on a vanilla Astro project (no adapter): delete node_modules/.vite, start astro dev, navigate to /. Before: new dependencies optimized: astro/runtime/client/dev-toolbar/entrypoint.js + reload.

+'astro': patch

+Adds the dev toolbar entrypoint to the client `optimizeDeps.include` to prevent a full page reload on first navigation during dev


Reword the changeset to make it user-facing. I don't think users need to know about optimizeDeps.include`

Framework components imported from MDX content entries are only reachable through the virtual astro:content module, which Vite's dep scanner cannot follow, so their framework dependencies were never pre-bundled at cold start. When the browser then requested them at runtime, Vite re-optimized and sent a full-reload, reloading the page once shortly after the first load. Add mdx to optimizeDeps.entries in both the runnable and client environments, mirroring the .astro entry added in #16480. Plain .md files cannot import components, so only .mdx needs scanning.

… HMR after ClientRouter navigation (#17953) * fix(content): preserve Vite module ID in content entry CSS propagation for HMR * test(render): fix SSRResult typing in renderUniqueStylesheet unit test The test result mock only provided { styles }, which does not satisfy SSRResult and broke tsc -b during the build. Cast the mock so the test typechecks. * test(content): cover content-propagation CSS HMR after ClientRouter navigation Adds an e2e test that navigates away and back with ClientRouter, then edits a Svelte component rendered through a content entry and verifies the change applies via HMR without a full reload. The load counter starts after the initial page settles so Vite's one-time cold-start re-optimization reload is not counted against the navigation flow. * fix(dev): include MDX files in the optimizeDeps scan Framework components imported from MDX content entries are only reachable through the virtual astro:content module, which Vite's dep scanner cannot follow, so their framework dependencies were never pre-bundled at cold start. When the browser then requested them at runtime, Vite re-optimized and sent a full-reload, reloading the page once shortly after the first load. Add mdx to optimizeDeps.entries in both the runnable and client environments, mirroring the .astro entry added in #16480. Plain .md files cannot import components, so only .mdx needs scanning. --------- Co-authored-by: factory[bot] <factory[bot]@users.noreply.github.com> Co-authored-by: Matthew Phillips <matthew@matthewphillips.info>
