Scaffold a New Sitecore Marketplace App

You are helping the user scaffold a new Sitecore Marketplace app using the official Sitecore Marketplace SDK (v0.4).

Step 1: Gather Requirements

Ask the user the following questions (skip any they've already answered):

• App name — What should the app be called? (default: from $ARGUMENTS if provided)

• Architecture — Client-side only or full-stack?

• Client-side: UI runs entirely in the iframe, communicates via SDK client. Simpler, no server needed.

• Full-stack: Includes Next.js API routes/server actions for server-side SDK access. Required for Auth0, server-side mutations, or proxying external APIs.

• Authentication — Built-in (default) or Auth0?

• Built-in: Zero-config, SDK handles auth automatically. Sufficient for most apps.

• Auth0: Required for server-side API access, external service integration, or custom auth flows. Requires Auth0 tenant setup.

• Optional packages — Which additional SDK packages?

• XM Cloud (xmc ): Access Sites, Pages, Authoring, Content Transfer, Search, and Agent APIs

• AI Skills (ai ): Access Brand Review API for AI-powered content analysis

Step 2: Run the Scaffold Command

Based on answers, construct and run the appropriate command:

Client-side only (built-in auth)

npx shadcn@latest add https://marketplace-sdk.sitecorecloud.io/r/app-client.json

Client-side + XMC

npx shadcn@latest add https://marketplace-sdk.sitecorecloud.io/r/app-client.json https://marketplace-sdk.sitecorecloud.io/r/xmc.json

Client-side + AI

npx shadcn@latest add https://marketplace-sdk.sitecorecloud.io/r/app-client.json https://marketplace-sdk.sitecorecloud.io/r/ai.json

Client-side + XMC + AI

npx shadcn@latest add https://marketplace-sdk.sitecorecloud.io/r/app-client.json https://marketplace-sdk.sitecorecloud.io/r/xmc.json https://marketplace-sdk.sitecorecloud.io/r/ai.json

Full-stack (Auth0) — adds server-side SDK support

npx shadcn@latest add https://marketplace-sdk.sitecorecloud.io/r/app-auth0.json

Full-stack + XMC

npx shadcn@latest add https://marketplace-sdk.sitecorecloud.io/r/app-auth0.json https://marketplace-sdk.sitecorecloud.io/r/xmc.json

Full-stack + AI

npx shadcn@latest add https://marketplace-sdk.sitecorecloud.io/r/app-auth0.json https://marketplace-sdk.sitecorecloud.io/r/ai.json

Full-stack + XMC + AI

npx shadcn@latest add https://marketplace-sdk.sitecorecloud.io/r/app-auth0.json https://marketplace-sdk.sitecorecloud.io/r/xmc.json https://marketplace-sdk.sitecorecloud.io/r/ai.json

Important: If the user doesn't have a Next.js project yet, scaffold one first:

npx create-next-app@latest <app-name> --typescript --tailwind --eslint --app --src-dir cd <app-name>

Step 3: Post-Scaffold Setup

After scaffolding completes:

Create .env.local — See env-template.md for the template. Fill in based on architecture choice.

Configure CSP headers — Add iframe embedding headers to next.config.ts :

const nextConfig: NextConfig = { async headers() { return [ { source: "/(.)", headers: [ { key: "Content-Security-Policy", value: "frame-ancestors 'self' https://.sitecorecloud.io", }, ], }, ]; }, };

• Install Blok theme (if not already present):

npx shadcn@latest add https://marketplace-sdk.sitecorecloud.io/r/blok-theme.json

• Verify setup — Run the dev server and confirm no errors:

npm run dev

Step 4: Explain Next Steps

After successful scaffold, suggest:

• Use /marketplace-add-extension to add extension point routes (custom fields, dashboard widgets, etc.)

• Use /marketplace-sdk-reference to look up SDK APIs

• Use /marketplace-build-component to build UI with the Blok design system

• Use /marketplace-deploy when ready to deploy
