This is a Next.js project bootstrapped with create-next-app.

Getting Started

First, run the development server:

npm run dev
# or
yarn dev
# or
pnpm dev
# or
bun dev

Open http://localhost:3000 with your browser to see the result.

You can start editing the page by modifying app/page.tsx. The page auto-updates as you edit the file.

This project uses next/font to automatically optimize and load Geist, a new font family for Vercel.

Export Bundle (Landing ZIP)

The Builder can export a production-ready ZIP that contains:

• index.html, styles.css, app.js
• assets/ hashed assets (optionally grouped by type)
• site.webmanifest, robots.txt
• Optional: sheets/ (Google Apps Script template)
• Metadata files: assets.json, assets.index.json

Export Options UI

• Manifest
  • Name, Short Name, Start URL, Display (dropdown), Theme Color (HEX only)
• Robots
  • Disallow lines (textarea). Each line becomes a Disallow: rule.
• Google Sheets Template Mode
  • Auto: include when form.actionUrl is empty
  • Include: always include
  • Exclude: never include

site.webmanifest and robots.txt

• site.webmanifest is derived from page data; Export Options can override fields.
• robots.txt defaults to a permissive header and adds Disallow lines from UI.

Asset paths and grouping

• AssetManager writes files to assets/ with stable hash-based filenames.
• Path strategy can be configured:
  • flat (default): assets/<hash>.<ext>
  • grouped: assets/images/..., assets/fonts/..., assets/other/...

assets.json

Structured metadata for all assets. Example fields per entry:

• originalName, mimeType, size
• hash8, ext, zipPath
• integrity: sha256-<base64> (placeholder, base64 of bytes)
• group: images|fonts|other
• referencedAt: array of local:<originalName> when referenced by the page

assets.index.json

Simple index to quickly find assets by group:

• images: string[] of zip paths
• fonts: string[] of zip paths
• other: string[] of zip paths

Google Sheets template (optional)

• When included, ZIP contains:
  • sheets/Code.gs: minimal Apps Script handler (Web App)
  • sheets/README.txt: setup instructions
• Inclusion is controlled by sheetsMode (Auto/Include/Exclude) and form.actionUrl in Auto mode.
