feat: add themes (.orskin) category with live color swatches and preview by ClausValcaTD · Pull Request #18 · M5Devs/OpenROM-Store

ClausValcaTD · 2026-11-05T23:31:54Z

What changed

OpenROM themes (.orskin) become a first-class storefront category next to the
executable extensions, with live colour swatches on the cards and a palette
inspector plus mockup preview on the detail page.

                                                          Inspector + Apply in OpenROM

No schema change was needed. A theme is an ordinary plugins row with
category = 'Themes', reusing the columns that normally describe conversion
tooling:

Column	For a plugin	For a theme
`routes_json`	`["ISO -> WUA"]`	`["#0d0e15","#161926","#e94560","#00f0ff","#ffffff"]`
`platforms_json`	`["Windows","Linux"]`	`["All Platforms"]`

The palette is read positionally as Background, Surface, Accent and Text.

Security: the palette is untrusted input

Those hex strings come from D1 and are rendered into style attributes, so
without validation a crafted palette could break out of the attribute.
src/lib/theme.ts validates every colour against #rgb/#rgba/#rrggbb/#rrggbbaa
and drops anything else before it can reach a template:

const HEX_COLOR = /^#(?:[0-9a-f]{3}|[0-9a-f]{4}|[0-9a-f]{6}|[0-9a-f]{8})$/i;

I verified this at runtime by writing a malicious palette into D1
(["#0d0e15","red;}body{display:none","url(javascript:alert(1))","#00f0ff"])
and parsing the rendered HTML: the two valid colours render, the two payloads
are dropped, and no injected element or attribute ever appears. contrastText
picks a readable foreground by relative luminance so the preview stays legible
on any palette.

Verification

Check	Result
`npm run build`	exit 0
`npm test`	62/62 (13 new in `tests/theme.test.ts`)
`tsc` on `src/`	clean
Themes filter	isolates only the theme card (1 of 5)
Theme card	5 swatches, "Download .orskin", `data-copy-cli="openrom://theme/cyberpunk-neon"`
`/plugin/cyberpunk-neon`	Live Preview + Palette Inspector (4 roles, copy per hex) + Apply in OpenROM
`/api/download/cyberpunk-neon`	`302 → /themes/cyberpunk-neon.orskin`, counter increments
Static `.orskin`	200, byte-identical to source, valid JSON
Non-theme page (`/plugin/nkit`)	unchanged — routes, CLI install, `.orplug` all intact
Malicious palette in D1	payloads dropped, no element/attribute injection

Notes

The launch theme Cyberpunk Neon 1.0.0 by M5 Dev is registered by data
migration 0006 and ships at public/themes/cyberpunk-neon.orskin; the
migration records that file's real SHA-256.
The download URL is root-relative (/themes/cyberpunk-neon.orskin). The
task suggested an absolute https://openrom-store.pages.dev/... URL, but a
relative Location works identically in production while also working on
Cloudflare preview deployments and local wrangler pages dev — an absolute
hostname would break the last two. Easy to change if you'd rather pin it.
The task's seed listed publisher_id: m5dev while the description said
"publisher_id: m5dev" / "publisher_name: M5 Dev" — I used m5dev (matching
migration 0005's publisher row) with display name M5 Dev.

Summary by CodeRabbit

New Features
- Added the Cyberpunk Neon theme, featuring a dark palette with pink and cyan accents.
- Theme pages now include a color preview, palette details, and theme-specific apply, download, and installation options.
- Theme listings display color swatches and clearer category and download labels; themes are included in category filters.
- Added support for all-platform theme listings.

OpenROM now supports UI themes as `.orskin` palette files, so the storefront gains a first-class Themes category alongside the executable extensions. A theme is an ordinary `plugins` row with `category = 'Themes'`; no schema change was needed. The columns that normally describe conversion tooling carry the payload instead: `routes_json` holds the colour palette as an array of hex strings, and `platforms_json` is `["All Platforms"]` because a theme is not OS-specific. The storefront reads the palette positionally as Background, Surface, Accent and Text. Palette values come from D1, so they are untrusted input. `src/lib/theme.ts` validates every colour against `#rgb`/`#rgba`/`#rrggbb`/`#rrggbbaa` before it can reach a `style` attribute and drops anything else, so a crafted palette cannot break out of the attribute. `contrastText` picks a readable foreground by relative luminance so the preview stays legible on any palette. - Storefront: the Themes filter appears with a 🎨 label; a theme card swaps the conversion-route chips for a live swatch bar (up to 5 pills with a glow), and its actions become "Copy URI" (`openrom://theme/<id>`) and "Download .orskin". - Detail page: themes get a Live Preview mock OpenROM window painted with the theme's exact colours (with ROMeo), a Colour Palette Inspector listing Background/Surface/Accent/Text with 1-click copy for each hex, an "Apply in OpenROM" deep link and a "Download .orskin" button. The manifest panel labels the array `palette` rather than `routes` for a theme. - Seed: migration 0006 registers the verified launch theme Cyberpunk Neon 1.0.0 by M5 Dev, and `public/themes/cyberpunk-neon.orskin` ships the matching palette (the migration records its real SHA-256). The download URL is root-relative so it works on production, preview deployments and local wrangler alike. - tests/theme.test.ts covers hex validation including injection payloads, the role mapping, contrast selection and the deep-link/file-name helpers.

Walkthrough

The change adds the Cyberpunk Neon theme to the catalog and skin files. Theme helpers validate and map palette colors, and storefront cards and plugin pages provide theme-specific previews, apply links, downloads, and installation instructions.

Changes: Cyberpunk Neon theme support

Layer / File(s)	Summary
Theme package and catalog registration `public/themes/cyberpunk-neon.orskin`, `migrations/0006_cyberpunk_neon_theme.sql`	Adds the Cyberpunk Neon skin configuration and registers its publisher and plugin record. The upsert refreshes plugin fields without changing an existing download count.
Theme helpers and category labels `src/lib/theme.ts`, `src/lib/site.ts`, `tests/theme.test.ts`	Adds theme detection, color validation, palette and swatch mapping, contrast text selection, URI and filename helpers, and category labels. Tests cover the theme helpers and constants.
Theme-aware catalog cards `src/components/Card.astro`, `src/components/CategoryFilter.astro`, `src/components/Icon.astro`, `src/lib/site.ts`	Catalog cards show theme swatches and theme-specific copy and download labels. Category controls use formatted category labels. The icon map adds a palette icon, and platform icons include an all-platforms entry.
Theme plugin detail page `src/pages/plugin/[id].astro`	Theme pages expose a palette manifest, render a palette preview and inspector, and provide theme-specific apply, download, and installation instructions. Non-theme plugin flows remain available.

Include all-platform themes in platform filters

When a user selects Windows, Linux, or macOS, the exact-match filter hides Cyberpunk Neon. Treat All Platforms as a match for each selected platform.

Suggested fix

In src/pages/index.astro:

const matchesPlatform = - state.platforms.size === 0 || platforms.some((p) => state.platforms.has(p)); + state.platforms.size === 0 || + platforms.includes('All Platforms') || + platforms.some((p) => state.platforms.has(p));
