The shared design language, NUI plumbing and FiveM CEF workarounds behind every 9AM Studios script.

Distributed as a shadcn registry: components are copied into each script rather than imported from a package, so a script can diverge when it genuinely needs to — while 9am-ui check makes sure nobody diverges by accident.

Extracted from 9am-vehicleshop v1.2.8, which is consumer #0.

Browse it all: bun run preview → http://localhost:5173.

@9am/viewport is the house scroll container: a drag-able custom scrollbar, layered "liquid glass" edge blur, and a header that blur-swaps to a sticky copy as you scroll. It also carries the CEF-103 workarounds — clipPath instead of overflow+radius, stacked fixed-blur bands because mask doesn't apply to backdrop-filter output, and JS-computed grid columns because :has() and @container don't exist in Chromium 103.

@9am/smooth-scroll exists because CEF will not wheel-scroll a clip-path'd container at all. Without it, the viewport is unscrollable in-game while working fine in your browser.

mkdir -p my-script/web && cd my-script/web
bun init -y

Add components.json:

{
  "$schema": "https://ui.shadcn.com/schema.json",
  "style": "new-york", "rsc": false, "tsx": true,
  "tailwind": {
    "config": "", "css": "src/index.css",
    "baseColor": "neutral", "cssVariables": true, "prefix": ""
  },
  "aliases": {
    "components": "@/components", "utils": "@/lib/utils",
    "ui": "@/components/ui", "lib": "@/lib", "hooks": "@/hooks"
  },
  "registries": {
    "@9am": {
      "url": "https://raw.githubusercontent.com/ilovehugetits/9am-ui/main/r/{name}.json"
    }
  }
}

Then:

bunx shadcn@latest add @9am/scaffold     # web skeleton + every dependency
cd .. && bunx 9am-ui lua                 # Lua side, from the resource root

The CLI is on npm as 9am-ui. Examples use bunx because the rest of the kit assumes bun, but npx 9am-ui works identically — the published binary is plain ESM with a node shebang.

Finally, edit web/src/nui.config.ts — it is the one kit file you are meant to change:

export const nuiConfig = {
  resourceName: "my-script",
  themeStorageKey: "my-script:theme",
  defaultTheme: "dark",
}

Keep the localStorage key in index.html in sync with themeStorageKey (it runs before first paint to avoid a theme flash), then:

cd web && bun install && bun run build
bunx 9am-ui doctor    # confirms the registry, theme import and the CEF css setup

Add the registries block above to your components.json, then take what you want:

bunx shadcn@latest add @9am/theme @9am/viewport @9am/data-table

Transitive dependencies resolve automatically — @9am/data-table pulls button, input, table, i18n and its three icons.

After adding @9am/theme, import it from your entry stylesheet:

@import "tailwindcss";
@import "tw-animate-css";
@import "./styles/9am-fonts.css";   /* or 9am-fonts-linked.css — see below */
@import "./styles/9am-theme.css";

9am-theme.css deliberately does not import a font stylesheet, because which one you want depends on your app:

Embedding is the better default: one command, nothing else to fetch, and in a NUI everything is served off local disk so there is no network round-trip to save. It becomes the wrong choice as soon as you have multiple entry points — every DUI is its own CEF instance, so each one would decode the entire 322 KB payload again with nothing shared between them.

9am-vehicleshop is the worked example: it has three entries (main NUI, phone, showroom stand) and client/showroom.lua calls CreateDui once per showroom slot, so it uses the linked variant everywhere.

FiveM's CEF is Chromium 103. Two things will silently ruin a build:

1. postcss.config.js must keep postcss-color-converter. The tokens are authored in oklch(), which CEF cannot parse. Without the conversion the UI renders completely unstyled in-game while looking perfect in bun run start. Verify with:

   bun run build && grep -c oklch dist/assets/*.css   # must be 0

2. installSmoothScroll() must run in main.tsx. Otherwise nothing scrolls in-game.

bunx 9am-ui doctor checks both, including scanning your built CSS for surviving oklch().

bunx 9am-ui check     # run from web/, wire it into CI

bun run build       # regenerates fonts, registry.json and r/
bun run typecheck
bun run preview     # eyeball it in both themes
git commit -am "feat(button): ..." && git push

r/ is committed on purpose — raw.githubusercontent.com serves committed files, which is what lets this repo act as a registry with no hosting at all.

Consumers pick the change up on their next shadcn add ... --overwrite. Nothing auto-updates; that is deliberate.
