Instructions

Entry points in this repo

File	Role
lib/contentstack.ts	`getStack()`, `initLivePreview()`, `getPage()` — core SDK and preview behavior
app/page.tsx	Server page: reads Live Preview `searchParams`, applies `livePreviewQuery`, fetches page
components/ContentstackLivePreview.tsx	Client component: calls `initLivePreview()` when preview is enabled
lib/types.ts	TypeScript shapes for `Page` and nested modular blocks (matches seeded content)
app/layout.tsx	Imports app/globals.css and mounts `<ContentstackLivePreview />` after `{children}`

Request isolation (`getStack`)

Always create a fresh stack per server request when handling delivery or preview on the server. See the comments in lib/contentstack.ts: a shared instance can leak Live Preview configuration across concurrent requests.
getPage(url, stackInstance?) accepts an optional stack so the caller can configure Live Preview on the same instance before fetching.

Live Preview (SSR)

URL/query: Contentstack adds query parameters (e.g. live_preview, content_type_uid, entry_uid, preview_timestamp). app/page.tsx reads them from searchParams.
Server: If live_preview is present, call stack.livePreviewQuery({ ... }) on the stack from getStack(), then pass that stack into getPage("/", stack).
Client: components/ContentstackLivePreview.tsx runs initLivePreview() inside useEffect when NEXT_PUBLIC_CONTENTSTACK_PREVIEW === "true". That uses ssr: true and mode: "builder" in lib/contentstack.ts.

Content query

Default page fetch uses content type page, field url with QueryOperation.EQUALS, wired in lib/contentstack.ts.
When preview is enabled, contentstack.Utils.addEditableTags is applied to the entry for visual building.

Environment variables

Documented in README.md. All are NEXT_PUBLIC_* in this template (browser-visible). Typical set:

NEXT_PUBLIC_CONTENTSTACK_API_KEY
NEXT_PUBLIC_CONTENTSTACK_DELIVERY_TOKEN
NEXT_PUBLIC_CONTENTSTACK_PREVIEW_TOKEN
NEXT_PUBLIC_CONTENTSTACK_REGION
NEXT_PUBLIC_CONTENTSTACK_ENVIRONMENT
NEXT_PUBLIC_CONTENTSTACK_PREVIEW

Optional overrides for hosts (used internally at Contentstack) appear in lib/contentstack.ts: NEXT_PUBLIC_CONTENTSTACK_CONTENT_DELIVERY, NEXT_PUBLIC_CONTENTSTACK_PREVIEW_HOST, NEXT_PUBLIC_CONTENTSTACK_CONTENT_APPLICATION, NEXT_PUBLIC_CONTENTSTACK_IMAGE_HOSTNAME (see next.config.mjs for image host allowlist).
