jsonapi_frontend_layout

jsonapi_frontend_layout is an optional add-on for jsonapi_frontend that enables true headless Layout Builder rendering by exposing a normalized layout tree
API.

Features

• Adds GET /jsonapi/layout/resolve?path=/about-us&_format=json
• Uses jsonapi_frontend for alias/redirect/language negotiation + access checks
• When applicable, returns a layout tree (sections + components) alongside the normal resolver contract
• MVP component support: field blocks and inline blocks (returns JSON:API references for block content when possible)

Post-Installation

1. Install and enable jsonapi_frontend and layout_builder.
2. Enable Layout Builder for a bundle’s display (Manage display → enable Layout Builder).
3. Request: GET /jsonapi/layout/resolve?path=/your-page&_format=json
4. In your frontend: use the returned layout tree to render sections/components, and fetch any referenced JSON:API URLs. li>

provides a consistent, resolver-aligned layout tree endpoint designed for modern frontends.
