This adds basic support for the new Section Library starter repo structure. This includes some of the following updates:

  • Added Section Library discovery and validation from src/library
  • Added public SectionConfig and MainContent support for library section configs
  • Generated a Puck config with only library sections, not the built-in Visual Editor components
  • Generated Pages render/editor templates, including temporary main and edit aliases to make this work without platform changes
  • Generated the Section Library artifact manifest (which is not yet used) and the temporary legacy template manifest

Currently, this only supports a single ENTITY layout (DIRECTORY, LOCATOR, and multiple ENTITY layout support will be added later).

Tested in platform on this site and confirmed it works without any platform changes.

Walkthrough

The visual editor now supports Entity-only Section Library generation through its Vite plugin. The generator validates metadata, sections, layouts, references, and JSON inputs. It creates configuration, render, editor, and manifest files. The plugin controls generation, manifest emission, and cleanup. The package exports SectionConfig, MainContent, and plugin declarations. Plugin builds now emit declarations and externalize runtime dependencies.

108-208: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

Add a case for a repository without src/library/library.json.

The it.each table covers invalid inputs well. It does not cover the absent-library path. generateSectionLibraryFiles returns { generatedFiles: [] } in that case and writes nothing. That branch controls whether packages/visual-editor/src/vite-plugin/plugin.ts produces an empty build, so it deserves a test.

💚 Proposed additional test

Remove the duplicate file read and the assertions on absent strings.

Lines 36-39 assert that the output does not contain mainConfig, directoryConfig, locatorConfig, and Object.groupBy. buildConfigSource never emits those strings, and no requirement forbids them. These assertions pass unconditionally and do not describe the behavior under test.

localeCompare makes the generated output depend on the host locale.

readdirSync(...).sort((left, right) => left.name.localeCompare(right.name)) orders sections with the default locale collation. The order determines the Section${index} import order and the entry order in the generated libraryConfig.tsx. Two machines with different locales produce different bytes for the same input, which weakens build reproducibility and produces noisy diffs.

Use a fixed collation.

♻️ Proposed change for deterministic ordering

Replace the positional templatePaths indexing with named bindings.

collectComponentIds does not traverse root slots.

collectComponentIds reads only layout.content and layout.zones. collectComponentList traverses props.slots for each component, but nothing traverses root.props.slots. Puck stores slot content on root.props when the root render declares slots.

buildConfigSource generates a root render that uses <DropZone zone="default-zone" /> (Line 470), so current data lands in zones. If the root render moves to a slot field, validateLayoutReferences stops detecting missing sections, and the build succeeds with a layout that references a component Puck cannot resolve at render time.

Traverse root.props.slots for completeness.

♻️ Proposed change to cover root slots
 const collectComponentIds = (value: unknown): string[] => {
   if (!value || typeof value !== "object") {
     return [];
   }
   const layout = value as Record<string, unknown>;

The SectionConfig annotation check rejects valid TypeScript forms.

The check requires the declaration type to be a type reference whose typeName is the identifier SectionConfig. Three valid authoring forms fail:

  • import type { SectionConfig as SC } from "@yext/visual-editor"; export const config: SC = {...}
  • export const config = {...} satisfies SectionConfig;
  • A qualified name such as VE.SectionConfig.

Each produces the message config must use the SectionConfig type, which does not describe the real constraint. Document the required form in the error message, or accept satisfies expressions and qualified names.

♻️ Proposed change to clarify the constraint
-    throw new Error(`${sourcePath} config must use the SectionConfig type`);
+    throw new Error(
+      `${sourcePath} config must be annotated exactly as \`const config: SectionConfig\`. Aliased imports, qualified names, and \`satisfies\` are not supported.`

Consider not shipping typescript as a runtime dependency of the whole package.

typescript is only needed by the Vite plugin entry, which runs in Node during a build. Placing it in dependencies installs the full compiler for every consumer of the package, including consumers that import only components. A peerDependency (most consumers of a Pages starter already have typescript) or a peerDependenciesMeta optional entry keeps the plugin working without adding weight for component-only consumers.

If you keep it in dependencies, that is a deliberate tradeoff for zero-config plugin usage. Confirm the intent.

Match subpath specifiers for the non-builtin externals.

The predicate compares source for exact equality with "fs-extra" and "typescript". A subpath import such as fs-extra/esm or typescript/lib/typescript.js does not match, so Rollup tries to bundle it. The current sources import the bare specifiers, so this is not an active defect. A prefix match keeps the rule correct if an import changes later.

I don't think we can externalize these. That means any users of the plugin in the starter must now import these libs in their package.json.

fs-extra is a runtime dependency of the plug-in, so I moved it to Visual Editor’s dependencies. I think we should keep these Node-only packages externalized; npm will visual-editor's dependencies transitively, so the starter(s) shouldn't need to list them directly.

I recall reading somewhere that it defaults to "Sections" or something. Should that be handled here instead of wherever that is happening? I assume it's in the template wrapper.

I think it's better to handle that in the generated config where grouping occurs, so SectionConfig.category stays optional and the parser preserves the developer's provided config metadata.

this seems weird. Why is layoutId the path if resolve errors?
