Repository

Where Canon lives in the monorepo, how a component file is built, and the conventions every file follows.

The monorepo#

One Turborepo workspace on Bun. Apps consume packages; nothing in an app is imported by a package.

Inside packages/canon#

The package's exports map turns each folder into an import path. Counts are read from the file system on every build.

Canon documents 165 components. Some files export a whole family (dialog.tsx exports the root, trigger, content, header and footer), and a few internal helpers, such as choice-cards.tsx and the prompt editor's parts, have no page of their own.

Anatomy of a component file#

Every Canon file follows the same shape. Badge is the smallest complete example.

  1. Client directive. "use client" only when the file holds state, effects or event handlers. Button has it; Badge doesn't.
  2. Base UI primitive. Interactive parts wrap a primitive from @base-ui/react/<part>, which brings roles, focus management and keyboard behavior.
  3. cva variants. cva(base, { variants, defaultVariants }) holds the classes, and the variants object is exported so other files can borrow the look.
  4. data-slot. Each rendered part names itself, such as data-slot="badge". Parents style children through it (in-data-[slot=button-group]) and globals.css keys motion to it.
  5. render prop. useRender with mergeProps lets the component render as another element, such as a Next Link, keeping its classes, props and state.
  6. className last. cn(variants({ variant }), className) merges the caller's classes after the component's, so an override always wins.
  7. Named exports at the bottom. One export { Badge, badgeVariants } block closes the file. No default exports.

The render prop in button.tsx#

Button keeps Base UI's button semantics for native buttons. Given a render element such as a link, it renders that element through useRender instead, so links stay links.

packages/canon/src/components/button.tsx
function rendersNativeButton(render: ButtonPrimitive.Props["render"]) {    return (        render === undefined ||        typeof render === "function" ||        (React.isValidElement(render) && render.type === "button")    );}function Button({    className,    variant = "default",    size = "default",    ...props}: ButtonPrimitive.Props & VariantProps<typeof buttonVariants>) {    const classes = cn(buttonVariants({ variant, size, className }));    if (!rendersNativeButton(props.render)) {        const { render, nativeButton, focusableWhenDisabled, ...rest } = props;        return (            <ButtonElement                render={render as React.ReactElement}                className={classes}                {...(rest as React.ComponentProps<"button">)}            />        );    }    return (        <ButtonPrimitive data-slot="button" className={classes} {...props} />    );}// Links styled as buttons keep their link semantics instead of Base UI's// button role and keyboard handling.function ButtonElement({    render,    className,    ...props}: React.ComponentProps<"button"> & {    render: React.ReactElement;    className: string;}) {    return useRender({        render,        props: mergeProps<"button">({ className }, props),        state: { slot: "button" },    });}export { Button, buttonVariants };

Conventions#

The small agreements that let files compose without reading each other.

File conventions
ConventionRule
data-slotEvery rendered part sets one, in kebab case, prefixed by its component (dialog-content, settings-row). 548 distinct names exist today. globals.css keys open and close motion to 18 of them: dropdown-menu-content, dropdown-menu-sub-content, context-menu-content, context-menu-sub-content, menubar-content, popover-content, select-content, combobox-content, hover-card-content, tooltip-content, dialog-content, alert-dialog-content, dialog-overlay, alert-dialog-overlay, sheet-overlay, sheet-content, collapsible-content, illustration.
data-iconMark an icon inside a button or badge data-icon="inline-start" or "inline-end". The padding on that side tightens by 2px so the label stays optically centered.
Sizesxs 24px, sm 28px, default 32px and lg 36px, with square icon-xs, icon-sm, icon and icon-lg at the same heights.
type="button"A native button that doesn't submit a form says so. Base UI's Button sets it; hand-written <button> elements must.
IconsFrom lucide-react, aria-hidden="true" beside text, 16px unless a size class is set. globals.css sets every svg.lucide to a 1.75 stroke.
ExportsNamed exports in one block at the end of the file. No file in packages/canon has a default export.
Imports between Canon filesUse the public path, @oration/canon/components/<file>, even inside packages/canon. The save bar imports Button that way.
TimingMotion comes from spring and exit in @oration/canon/lib/springs. No hand-written durations.

Two cn functions

Most packages/canon files import cn from the bare cn package, which doesn't know text-13 or text-2xs are font sizes. App code should import cn from @oration/canon/lib/utils, which does.

The docs site#

Canon's pages live in the Handbook app, so every example renders real packages/canon code.

apps/handbook/src
components/design/  registry/   pages.ts (every page), rules.ts (named rules, refusals),              loaders.ts (generated), digest.ts (llms.txt), types.ts  kit/        authoring primitives: sections, tables, examples, code, usage  site/       sidebar, header, search, table of contents, page frame  content/    one folder per page: doc.tsx, demos.tsx, guidance.tsapp/design/  page.tsx                 the overview  [...slug]/page.tsx       every other page, driven by the registry  llms.txt/route.ts        the index and brief for agents  llms-full.txt/route.ts   every component's guidance and props

Add a page by adding an entry to registry/pages.ts, then run bun run design:sync in apps/handbook. It regenerates loaders.ts and writes a stub doc.tsx so a new entry never breaks the build. The authoring guide is components/design/README.md.

Tooling#

Commands read from the root, apps/web and apps/handbook package.json files.

Commands
CommandRunsUse it to
bun run devturbo run devStart the web app (next dev --port 3000).
bunx biome check --write <paths>Biome on the given filesFormat and lint, applying safe fixes. Pre-commit runs the same on staged files.
bun run lintturbo run lintCheck the whole repo without writing.
bun run check-typesNot definedType-check every package. In apps/web this is bun run typecheck.
bun run ui-add <name>Not definedPull a shadcn component. The ui alias in apps/web/components.json points at @oration/canon/components, so it lands in packages/canon.
bun run design:syncbun scripts/design-sync.tsRegenerate Canon's loaders and stubs after editing the registry. Run it in apps/handbook.
  • A shadcn component arrives in shadcn's style. Before anyone uses it, bring it onto Canon tokens, add data-slot names and write its page.
  • Never edit registry/loaders.ts by hand; design:sync owns it.
