This is a [Next.js](https://nextjs.org) project bootstrapped with [`create-next-app`](https://nextjs.org/docs/app/api-reference/cli/create-next-app).
## Getting Started
First, run the development server:
```bash
npm run dev
# or
yarn dev
# or
pnpm dev
# or
bun dev
```
Open [http://localhost:3000](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`](https://nextjs.org/docs/app/building-your-application/optimizing/fonts) to automatically optimize and load [Geist](https://vercel.com/font), a new font family for Vercel.
## Learn More
To learn more about Next.js, take a look at the following resources:
- [Next.js Documentation](https://nextjs.org/docs) - learn about Next.js features and API.
- [Learn Next.js](https://nextjs.org/learn) - an interactive Next.js tutorial.
You can check out [the Next.js GitHub repository](https://github.com/vercel/next.js) - your feedback and contributions are welcome!
## Deploy on Vercel
The easiest way to deploy your Next.js app is to use the [Vercel Platform](https://vercel.com/new?utm_medium=default-template&filter=next.js&utm_source=create-next-app&utm_campaign=create-next-app-readme) from the creators of Next.js.
Check out our [Next.js deployment documentation](https://nextjs.org/docs/app/building-your-application/deploying) for more details.
## 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
- Integrity: assets.integrity.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.
- Robots Meta: `<meta name="robots" content="...">` value (e.g. `noindex, nofollow`). Empty disables the tag.
- Google Sheets Template Mode
- Auto: include when `form.actionUrl` is empty
- Include: always include
- Exclude: never include
- Font Optimization
- Preconnect: toggle inclusion of Google Fonts preconnect links.
- Preload: preload & load Google Fonts stylesheet with `media="print" onload` pattern.
- Image Options
- Loading: `lazy` (default) or `eager` for `<img loading>`
- Decoding: `async` (default) or `sync` for `<img decoding>`
### 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.
- `meta name="robots"` can be injected via Export Options and is written in `<head>`.
### 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
### assets.integrity.index.json
- entries: array of `{ path, integrity, size }`
- `path`: asset `zipPath` (e.g. `assets/abcd1234.png` or grouped `assets/images/...`)
- `integrity`: `sha256-<base64>` (real SHA-256 of the asset bytes)
- `size`: byte length of the asset
- bundleHash: `sha256-<base64>` over a deterministic join of `path` and `integrity` for all entries
Usage:
- Verify file-level integrity by recomputing SHA-256(base64) of each asset and comparing with `entries[].integrity`.
- Verify file size matches `entries[].size`.
- Verify bundle integrity by recomputing `bundleHash` from sorted entries; useful for quick tamper detection.
### 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.
