# Vision Start — Project Context

A general, non-normative overview of the **Vision Start** project: what it is, how it's structured, what features it offers, and which files do what. This document is intended as a map for humans and AI agents to orient themselves in the codebase. It deliberately avoids coding-style prescriptive rules.

---

## 1. What Is This Project?

**Vision Start** is a glassmorphism-styled, highly customizable **browser startpage** (new-tab page).

- Distributed as a **Chrome/Chromium extension** (Manifest V3) that overrides the new tab with `index.html`.
- Also runnable as a **standalone web app** and shipped as a **Docker image** served via nginx.
- Built with **React + TypeScript**, bundled with **Vite**, and styled with **Tailwind CSS v4** (using the `@preact/preset-vite` so Preact is the actual React runtime).
- Persistent state lives in `localStorage` and, when available, `chrome.storage.local`.

Live instances / artifacts:
- Public demo: `http://vision-start.ivanch.me`
- Source: `https://gitea.com/ivan/vision-start.git`
- Container registry: `git.ivanch.me/ivanch/vision-start`
- Releases: `https://git.ivanch.me/ivanch/vision-start/releases/latest`

## 2. Technology Stack

| Layer | Tech |
|---|---|
| Language | TypeScript (~5.7), target ES2020, strict mode |
| UI runtime | Preact 10 (via `@preact/preset-vite`); types from `@types/react` 19 |
| Bundler / dev server | Vite 6 |
| Styling | Tailwind CSS v4 (`@tailwindcss/vite` plugin + `@tailwindcss/postcss` + `autoprefixer`) |
| Drag & drop | `@hello-pangea/dnd` 18 |
| Build output | Plain static files in `dist/` (relative `base: './'`, single CSS bundle; modals code-split into separate JS chunks via `React.lazy`) |
| Container | Node 22 Alpine build stage → nginx Alpine serving `dist/` |
| Extension packaging | Manifest V3 (`manifest.json`) consuming `dist/` + `manifest.json` zipped as `vision-start-<tag>.zip` |
| CI/CD | Gitea Actions workflows (`.gitea/workflows/`) |
| Release screenshots | Playwright 1.61.1 + Chromium capture the deployed production page at a fixed 1280×800 viewport |

Entry points: `index.html` → `index.tsx` → `App.tsx`.

## 3. Feature Overview

The startpage is composed of widgets and a configuration panel:

- **Website Tiles** — Bookmarks organized into categories. Each tile shows an icon + name and opens the configured URL. Tiles can be added, edited, deleted, and moved left/right within their own category (reordering) while in edit mode.
- **Categories** — Groupings of website tiles (e.g. "Search"). Add/edit/delete/name.
- **Clock** — Optional header clock with selectable size, font, and 12h/24h format.
- **Title** — Optional big header title (text + size configurable).
- **Server Status Widget** — Bottom-center glass pill that periodically "pings" configured server addresses and shows online/offline indicators. Ping uses an image-load trick (`components/utils/jsping.js`) with a 5s timeout, at a configurable frequency.
- **Wallpaper background** — Fullscreen background image with adjustable blur, brightness, and opacity, rendered behind a soft readability layer for the liquid-glass UI. Randomly rotates through multiple wallpapers at an hourly cadence selected by slider (`1h`–`48h`).
  - Built-in wallpapers: Abstract, Abstract Red, Beach, Dark, Mountain, Waves (`components/utils/baseWallpapers.ts`).
  - User wallpapers: upload from a file (≤4MB, ≤4.5MB base64) or add by URL. Remote URLs remain lightweight entries in the `userWallpapers` index; uploaded image data is stored in `chrome.storage.local` when available.
- **Icon library, auto-fetch & cache** — Website icons can be picked from the [Dashboard Icons](https://dashboardicons.com/) library (metadata pre-downloaded to `public/icon-metadata.json`) or auto-fetched for trusted public TLDs as a Google S2 favicon URL derived from the site's hostname (no HTML fetching — the S2 URL is used purely as an `<img>` source). Non-trusted TLDs (e.g. local TLDs, IP addresses) fetch `${origin}/favicon.ico` directly. Tiles opportunistically cache CORS-readable icon responses as data URLs in `chrome.storage.local` and retain the original URL when caching is unavailable. Cache population fetches trusted TLDs through a CORS-open favicon service (`icon.horse`) because Google's S2 endpoint 301-redirects without `Access-Control-Allow-Origin`, which would block cross-origin `fetch`.
- **Configuration panel** — Slide-in right-side modal with four tabs: General, Theme, Clock, Server Widget. Includes **Export** (downloads a JSON bundle of selected `localStorage` keys) and **Import** (restores from JSON and reloads the page).
- **Edit mode** — Toggle via the top-left pencil button; reveals per-tile glass action toolbars, per-category edit buttons, and ghost glass "add" tiles.
- **Liquid glass design language** — Soft translucent surfaces, restrained edge highlights, moderate backdrop blur, soft shadows, cyan focus states, and iOS-like easing tokens (`ease-ios`, `ease-spring`, `ease-liquid`) defined in `index.css`.

Performance notes:
- Website tile icons check a deterministic `vision-start:icon:<encoded-source-url>` entry in `chrome.storage.local` before loading the external URL. Cache population fetches Google S2 favicon URLs for trusted public TLDs through `https://icon.horse/icon/<host>` (a CORS-open favicon service), while non-trusted TLDs and direct icon URLs render directly in `<img>` tags without triggering background `fetch` calls. It deduplicates in-flight requests, stores only `image/*` responses up to 256KiB, and never intercepts or proxies outside requests.
- Modals (`ConfigurationModal`, `WebsiteEditModal`, `CategoryEditModal`) are code-split via `React.lazy` + `Suspense` and only loaded when opened. `ConfigurationModal` is the heaviest chunk (it pulls in `@hello-pangea/dnd` via `ServerWidgetTab`); the rest of `@hello-pangea/dnd` is isolated from the initial load. `WebsiteEditModal` and `CategoryEditModal` share a common `ModalShell` component.
- `WebsiteTile` and `CategoryGroup` are wrapped in `React.memo`; `App.tsx` handlers are `useCallback`-stabilized and pure alignment helpers are hoisted to module scope, so opening a modal / toggling edit no longer re-renders every tile.
- `Clock` updates on the minute boundary (one `setTimeout` → `setInterval(60_000)`) instead of every second.
- `jsping` cancels its 5s timeout on image resolve/error and nulls the `Image` handlers, preventing leaks across ping cycles.
- `ServerWidget` batches pending-status updates into one `setState` and depends on a stable servers signature (ids+addresses) so unrelated config edits don't restart pings.
- Icon metadata (`/icon-metadata.json`) is fetched lazily on first focus of the icon field with `cache: 'force-cache'`, filter debounced ~150ms, and color variants are expanded lazily during filtering rather than upfront. The module-level metadata cache is released when the picker modal unmounts (the browser HTTP cache makes reopening cheap), and the dashboard-icon URL for a picker entry is derived from one shared helper.
- `Wallpaper` resolves wallpaper URLs through a module-level `Map` bounded to the last 3 entries — so uploaded base64 wallpapers (up to ~4.5MB strings) are not retained in memory for the page's lifetime; its image transition and readability overlay classes live in `index.css`. Wallpaper rotation and frequency parsing (`h`/`d` → hours/ms) share helpers with the Theme tab via `components/utils/wallpaperUtils.ts`.
- The website icon service keeps an in-memory resolved data-URL cache bounded to 50 entries (FIFO eviction) to avoid unbounded growth from many tiles.
- Shared styling/frequency helpers live in `components/utils/styleUtils.ts` (tile/clock/title size classes, icon pixel sizes, alignment classes, size presets), `wallpaperUtils.ts`, and `urlUtils.ts` (URL→filename extraction, also used by wallpaper storage). Range sliders use the shared `RangeSlider` component; repeated glyphs (pencil, plus, trash, chevrons) use `components/icons.tsx`.

Planned / To-do (tracked in `README.md`):
- Dynamic Weather widget, Search Bar widget, draggable/resizable grid system, Notes/Scratchpad widget, theming (light/dark, accent colors, wallpaper-derived accents, minimal feel toggle), and a general "refactor everything" note.

## 5. Data Model & State

The icon service also resolves website icon URLs through the persistent CORS-safe cache used by `WebsiteTile`; this cache is separate from the `Website` data model.

The shape of all persisted data lives in `types.ts`:

- **`Website`** — `id`, `name`, `url`, `icon`, `categoryId`
- **`Server`** — `id`, `name`, `address`
- **`Category`** — `id`, `name`, `websites: Website[]`
- **`Wallpaper`** — `name`, optional `url` or `base64`
- **`Config`** — Everything else: title, wallpaper list + hourly frequency/blur/brightness/opacity, titleSize, vertical & horizontal alignment, tileSize, `clock {enabled, size, font, format}`, `serverWidget {enabled, pingFrequency, servers}`

`ConfigurationService` (`components/services/ConfigurationService.ts`) is the source of truth for default config and persistence helpers. Config loaded from `localStorage` (and imported from export files) is run through `normalizeConfig()`, a schema-driven deep merge against `DEFAULT_CONFIG`: nested blocks (`clock`, `serverWidget`) inherit new sub-fields added to defaults, stored values with the wrong type fall back to defaults, and keys absent from the default schema are pruned. The merge is self-healing — `App.tsx`'s persist-`useEffect` writes the normalized shape back to `localStorage` on first run.

Storage layout (browser-side):

| Key | Where | Contents |
|---|---|---|
| `config` | `localStorage` | The full `Config` JSON |
| `categories` | `localStorage` | `Category[]` JSON |
| `userWallpapers` | `localStorage` | `Wallpaper[]` index (names plus URLs for remote wallpapers) |
| `wallpaperState` | `localStorage` | `{ lastWallpaperChange, currentIndex }` for rotation |
| `<wallpaperName>` | `chrome.storage.local` (when available) | Base64 image data for uploaded wallpaper files and legacy URL wallpapers |
| `vision-start:icon:<encoded-source-url>` | `chrome.storage.local` (when available) | CORS-readable website icon data URL, capped at 256KiB |

Export/import bundles keys: `config`, `categories`, `userWallpapers`, `wallpaperState`. Remote wallpaper URLs are included through `userWallpapers`; uploaded image data and rebuildable icon cache entries are not included.

---

## 6. Application Flow (high level)

1. `index.html` loads `index.tsx`, which mounts `<App/>` into `#root`.
2. `App.tsx` initializes state from `localStorage` (`categories`) and `ConfigurationService.loadConfig()` (`config`), falling back to defaults.
3. `useEffect` hooks persist `config` and `categories` back to `localStorage` whenever they change.
4. The screen renders:
   - `<Wallpaper>` behind everything (fetches URL/base64 from base catalog or chrome.storage.local; rotates per frequency).
   - `<EditButton>` (top-left) and `<ConfigurationButton>` (top-right).
   - `<Header>` (clock + title).
   - One `<CategoryGroup>` per category (renders its `<WebsiteTile>`s and, in edit mode, add/edit/move controls).
   - Optional `<ServerWidget>` if enabled.
   - Conditionally one of: `<WebsiteEditModal>`, `<CategoryEditModal>`, `<ConfigurationModal>`.
5. Each `<WebsiteTile>` checks the icon cache before loading the external URL, then asynchronously populates the cache on a miss.
6. Edit / configuration interactions update central `App` state; the existing `useEffect`s persist it.

---

## 7. Build, Release & Deployment

### Local development / preview
```bash
npm install
npm run dev       # Vite dev server (note: PROJECT.md says prefer `npm run build` for real testing)
npm run build     # Production build → dist/
npm run preview   # Serve built dist/
```

### Chrome extension install (manual)
Build, then combine `dist/` + `manifest.json` into a folder and "Load unpacked" from `chrome://extensions`. The release workflow automates this zip.

### Docker
`Dockerfile` builds in Node 22 Alpine (`npm ci` → runs `scripts/prepare_release.sh` → `npm run build`) and serves `/app/dist` + `manifest.json` via nginx:alpine on port 80.

### CI/CD (Gitea Actions)
- `release.yaml` validates each `vX.Y.Z` tag and stamps the version into `manifest.json` (`"version": "0.0.0"` → the tag) in each build checkout before producing the extension archive and production image.
- **`pull-request.yaml`** — Triggers on pull request open, reopen, and synchronization. It builds and uploads a PR extension archive containing `dist/`, unpacks that archive in a separate Playwright job to generate the three demo screenshots, and uploads both artifacts (screenshots are retained for 30 days). For same-repository PRs, it maintains one Gitea PR comment with inline image attachments; fork PRs retain artifacts but skip the comment because their workflow token is read-only.
- After `deploy_vision_start` succeeds, `release.yaml` uses Playwright Chromium against the deployed production page and seeds each browser context from `scripts/demoData.json`. It regenerates `home.png`, `editing.png`, and `configuration.png` at exactly 1280×800, uploads them as artifacts (retained for 30 days), and attaches them as individual Gitea release assets.
- **`main.yaml`** — Triggers on push to `main` (and `workflow_dispatch`). Builds, pushes a `staging` multi-arch (amd64/arm64) image to `git.ivanch.me/ivanch/vision-start:staging`, then SSH-deploys on the staging host via `docker compose up -d --force-recreate`.
- **`release.yaml`** — Triggers on `v*` tags. Builds, zips `dist/` + `manifest.json` as `vision-start-<tag>.zip`, runs `scripts/check_virustotal.sh` against it (publishes analysis URL + detection ratio on the release body), creates a Gitea release, pushes a `latest` multi-arch image, and SSH-deploys to production.

Required CI secrets (referenced by the workflows): `REGISTRY_PASSWORD`, `HOST`, `USERNAME`, `KEY`, `PORT`, `STAGING_DIR`, `PROD_DIR`, `VIRUSTOTAL_APIKEY`.

External assets fetched at build time by `scripts/prepare_release.sh`:
- `https://raw.githubusercontent.com/homarr-labs/dashboard-icons/.../metadata.json` → `public/icon-metadata.json` (used by `WebsiteEditModal` for the icon picker; gitignored).

---

## 8. Notable Behaviors & Quirks

- **`EditModal.tsx` has been removed.** It was a legacy drag-and-drop editor that imported non-existent `lucide-react` and `./IconPicker`; it was never wired into `App.tsx`. Use `WebsiteEditModal.tsx` / `CategoryEditModal.tsx` instead, both of which share the `ModalShell` component.
- **`@hello-pangea/dnd`** is used only in `ServerWidgetTab.tsx` (server reorder), which itself is imported by the lazy-loaded `ConfigurationModal`, so it lives in a separate chunk and is absent from the initial page load. `WebsiteTile` moves tiles within their own category via simple left/right buttons (no cross-category movement), not drag-and-drop.
- **Chrome storage is optional.** `StorageLocalManager` checks availability once (`checkChromeStorageLocalAvailable`) and caches it. Remote wallpaper URLs work without it because their URLs live in `userWallpapers`; file upload is gated off when unavailable, and `addWallpaperToChromeStorageLocal` throws if called without it.
- **Wallpaper rotation** is time-based, evaluated on render/mount rather than via a timer. It reads `wallpaperState` from `localStorage`, selects a random non-current wallpaper when the frequency window has elapsed, and writes its index back; the frequency is clamped to 1–48 hours, while older saved values like `1d`/`2d` still resolve to their hour equivalents. The renderer clamps `currentIndex` to the valid range of the current selection and walks the list forward to find a wallpaper whose data actually resolves (so deleting the currently-displayed wallpaper, or shrinking the selection, never leaves the background blank); if no wallpaper resolves, the background layer is hidden. When the selection becomes empty, `wallpaperState` is reset and the background is hidden. A manual "Random Wallpaper" button in the Theme tab also picks a random non-current wallpaper and bumps a `wallpaperVersion` nonce in `App.tsx` that retriggers the renderer.
- **Icon picker** in `WebsiteEditModal` loads `/icon-metadata.json` at runtime and expands each icon's `colors` into duplicate-name entries so color variants are searchable.
- **Website icon cache** is persistent only in `chrome.storage.local`; it is rebuilt from website icon URLs after configuration import. Only `image/*` responses no larger than 256KiB are cached. Trusted public TLDs use Google S2 and the CORS-open `icon.horse` service for favicon caching, while non-trusted TLDs (local TLDs, IP addresses, custom domains) fetch `${origin}/favicon.ico` directly. No site HTML is ever fetched for icon discovery.
- **`tsconfig.json` does not emit JS** (`noEmit: true`, bundler resolution); Vite handles all transpilation.
- **`tailwind.config.js` safelists** a set of `w-[Npx]/h-[Npx]` classes because `WebsiteTile` generates tailwind classes dynamically from `tileSize` (`w-[42px]`, etc.).
- **Project guidance note** in `PROJECT.md`: do not use `npm run dev` for real verification — use `npm run build`.
- **`.claude/` and `.env.local`** are local-only / gitignored; not part of shipped artifacts.
