Next.js + Enonic XP Headless Integration (Next.XP)

Procedures

Step 1: Identify the workspace integration surface

1. Inspect the workspace for Next.js entry points (next.config.*, package.json with next dependency), Enonic XP app markers (build.gradle with com.enonic.xp), or existing Next.XP adapter references (@enonic/nextjs-adapter).
2. Execute node scripts/find-nextxp-targets.mjs . to inventory Next.js projects, .env files with ENONIC_* variables, component mapping files (_mappings.ts), and Guillotine query files when a Node runtime is available.
3. If a Node runtime is unavailable, inspect package.json, .env, and src/components/_mappings.ts manually to identify the integration surface.
4. If the workspace contains both an Enonic XP app and a Next.js frontend, confirm which side the task targets before proceeding.
5. If the workspace is not a Next.js + Enonic XP project, stop and explain that this skill does not apply.

Step 2: Configure the Enonic adapter

1. Read references/nextxp-reference.md before writing or modifying configuration.
2. Verify or create the .env (or .env.local for local development) file in the Next.js project root with the required variables:
   • ENONIC_API_TOKEN — shared secret for preview mode authentication.
   • ENONIC_APP_NAME — fully qualified Enonic application name (e.g., com.example.myproject).
   • ENONIC_MAPPINGS — locale-to-project/site mapping (e.g., en:intro/hmdb).
   • ENONIC_API — base URL for the Guillotine API endpoint (e.g., http://127.0.0.1:8080/site/).
3. Install the @enonic/nextjs-adapter package if not already present: npm install @enonic/nextjs-adapter.
4. Import @enonic/nextjs-adapter/baseMappings at the top of src/components/_mappings.ts to register built-in component renderers.
5. Verify the Next.js project was scaffolded from the nextxp-template or contains the expected file structure: src/components/_mappings.ts, src/app/[locale]/[[...contentPath]]/page.tsx, and API routes under src/app/api/.
6. Read references/compatibility.md to confirm version requirements between @enonic/nextjs-adapter (v4.x), Next.js (16+), React (19), and Enonic XP.

Step 3: Map content types to React components

1. Read references/nextxp-reference.md for the component registry API and mapping patterns.
2. Read references/examples.md for complete content type mapping examples including queries, views, and processors.
3. For each Enonic content type that needs a custom rendering: a. Create a Guillotine GraphQL query function in src/components/queries/ that fetches the fields specific to that content type using type introspection (... on AppName_ContentTypeName). b. For content types with HTML area (rich text) fields, use richTextQuery(fieldName) from @enonic/nextjs-adapter to generate the query fragment. See references/nextxp-reference.md for the rich text rendering section. c. Create a React view component in src/components/views/ that accepts FetchContentResult props and renders the fetched data. Use RichTextView from @enonic/nextjs-adapter/views/RichTextView for HTML area fields. d. Register both in src/components/_mappings.ts using ComponentRegistry.addContentType().
4. For page components (pages, parts, layouts): a. Define the component XML in the Enonic app under src/main/resources/site/pages/, parts/, or layouts/. b. Create a corresponding React component in src/components/pages/, parts/, or layouts/. Use LayoutProps for layouts and the named RegionView export for individual region rendering. c. Register using ComponentRegistry.addPage(), ComponentRegistry.addPart(), or ComponentRegistry.addLayout().
5. For layouts, use LayoutProps type and RegionView (singular, named export) for individual regions instead of RegionsView.
6. Use APP_NAME and APP_NAME_UNDERSCORED imports from @enonic/nextjs-adapter to keep content type references dynamic.

Step 4: Configure Guillotine data fetching

1. Read references/nextxp-reference.md for the Guillotine query structure and variable passing.
2. Write GraphQL queries that use $path:ID! as the primary variable for content retrieval via guillotine { get(key:$path) { ... } }.
3. Use type introspection to access content-type-specific fields: ... on AppName_ContentTypeName { data { ... } }.
4. For rich text fields (HtmlArea), use richTextQuery(fieldName) from the adapter instead of querying the field directly. Render with RichTextView from @enonic/nextjs-adapter/views/RichTextView.
5. For parts and configurable components, export a query object with query(path, context, config) and variables(path, context, config) functions.
6. Use processors (optional async functions) to post-process query results before passing to the view.
7. Use ComponentRegistry.setCommonQuery() for data shared across all page components. Remove the common query if not needed to optimize performance.
8. Use getUrl() and getAsset() helper functions from the adapter for URL handling that works in both standalone and Content Studio preview modes.
9. For macros in rich text, register them with ComponentRegistry.addMacro() before other components that use RichTextView. See references/nextxp-reference.md for the macro registration API.

Step 5: Enable Content Studio preview mode

1. Read references/nextxp-reference.md for full preview architecture details.
2. Install the Next.XP app in Enonic XP: XP Menu → Applications → Install → search "Next.XP".
3. Add the Next.XP app to the target site in Content Studio via the "Applications" combobox on the site edit view.
4. Verify default preview configuration: URL http://127.0.0.1:3000 and secret matching ENONIC_API_TOKEN.
5. For production, configure the Next.XP app with the deployed Next.js URL and shared secret via app config:

   nextjs.default.url = <Next.js app URL>
   nextjs.default.secret = <shared secret>
   

   Copy
6. Preview mode automatically switches the Guillotine API to the draft branch, while the public Next.js frontend uses the master (published) branch.
7. Use getUrl() in all component links to ensure URLs resolve correctly across preview, inline, and edit modes in Content Studio.
8. If preview shows a blank page, read references/troubleshooting.md for diagnostic steps.

Step 6: Deploy to production

1. Read references/nextxp-reference.md for the deployment checklist.
2. Deploy the Enonic app to Enonic Cloud using enonic cloud app install.
3. Create an ingress in Enonic Cloud to expose the Guillotine API (target path /site, public path /api).
4. Deploy the Next.js app to Vercel or another hosting platform.
5. Set production environment variables: ENONIC_API, ENONIC_APP_NAME, ENONIC_API_TOKEN, ENONIC_MAPPINGS.
6. Configure the Next.XP app in Enonic Cloud to point to the production Next.js URL.
7. Publish content in Content Studio to make it visible on the live frontend.

Step 7: Validate the integration

1. Execute node scripts/find-nextxp-targets.mjs . to confirm the adapter, mappings, and env configuration still resolve correctly.
2. Verify that standalone Next.js rendering works at http://localhost:3000 with published content.
3. Verify Content Studio preview renders correctly for both draft and published content.
4. Test content type mappings by visiting content URLs and confirming custom views render.
5. Use validateData() from @enonic/nextjs-adapter in the page handler to catch invalid content responses. See references/nextxp-reference.md for the SSG page handler pattern.
6. Run the workspace build (npm run build) to catch TypeScript or build errors.

Error Handling

• If Content Studio preview shows a blank page, read references/troubleshooting.md for preview proxy diagnostics, token mismatch detection, and CORS issues.
• If Guillotine queries return empty or unexpected data, verify the content type name matches the introspection pattern and test the query in GraphQL Playground at http://localhost:8080/site/<project>.
• If @enonic/nextjs-adapter imports fail, check references/compatibility.md for version requirements and confirm the package is installed.
• If content renders in preview but not on the public site, verify the content is published (moved from draft to master branch).
• If component mappings are not applied, verify registrations in _mappings.ts use the correct fully-qualified content type or component name with APP_NAME.
