From 3c3744631e6442661511f4531681c927f611075f Mon Sep 17 00:00:00 2001 From: OJ Kwon <1210596+kwonoj@users.noreply.github.com> Date: Sat, 21 Oct 2023 14:24:40 -0700 Subject: [PATCH] fix(loader_tree): propagate metadata to corresponding layout (#56956) ### What? - fixes test https://github.com/vercel/next.js/blob/17553c5e25c824ce04045066c24a8f138881473d/test/e2e/app-dir/metadata/metadata.test.ts#L487 The way next.js collects static metadata is read static metadata, and then read layout metadata to merge multiple metadatas into a single layout path (https://github.com/vercel/next.js/blob/17553c5e25c824ce04045066c24a8f138881473d/packages/next/src/lib/metadata/resolve-metadata.ts#L347-L352) When turbopack creates LoaderTree for the corresponding directory tree, it extracts `page` but skips metadata in result there are orphan components that have a metadata doesn't have layout metadata, as well as a component have a layout doesn't have metadata. Latter is being rendered as a page (since it have correct layout), which eventually falls back to the default metadata instead. PR trickles down the metadata when extracting page (creating a new component with `page`) to consolidates those. Also PR expands Metadata to have base_page property to capture where it has been originally exists, as we clone down metadata then do `fillMetadataSegment` against the current page where LoaderTree is being created it creates a wrong relative path. For example, currently ``` /icon.svg - opengragph/ - static -> path being `/opengraph/.../icon.svg` instead of `/icon.svg` ``` When recursively traverse directory tree, capture each components with corresponding base_page to calculate instead. Unfortunately this doesn't make pass all of the metadata tests; there are lot to dig more. Would like to scope PR in a reasonable size.
