Bklit UI

Composable chart components for React, distributed via the @bklit shadcn registry. Charts are installed as source into the user's project.

IMPORTANT: Run shadcn CLI commands with the project's package runner: npx shadcn@latest, pnpm dlx shadcn@latest, or bunx --bun shadcn@latest.

Current Project Context

!`npx shadcn@latest info --json`

Use the JSON above for framework, aliases, Tailwind version, installed components, and resolved paths. Confirm the @bklit registry is configured before adding charts.

Principles

1. Install before inventing. Use npx shadcn@latest add @bklit/<chart> — charts are registry components, not hand-rolled SVG.
2. Compose, don't flatten. Root chart → Grid → series → axes → ChartTooltip. See composition.md.
3. Theme with tokens. Use chartCssVars and --chart-* variables — never hardcode one-off colors. See theming.md.
4. Read the doc page first. Each chart has props, data shape, and examples at https://ui.bklit.com/docs/components/<slug>.
5. Browse variants. Gallery: https://ui.bklit.com/charts/<slug> — Studio: https://ui.bklit.com/studio?chart=<slug>.

Critical Rules

These rules are always enforced. Each links to Incorrect/Correct examples.

Composition → composition.md

• Series and axes live inside the root chart — LineChart, BarChart, AreaChart, etc.
• One root per chart — use ComposedChart for mixed series types.
• Grid before series so lines/bars render above grid lines.
• ChartTooltip as a chart child — required for crosshair and hover context.

Theming → theming.md

• Use chartCssVars from @bklitui/ui/charts instead of raw "var(--chart-…)" strings.
• Series palette: --chart-1 … --chart-5 for multi-series charts.
• Tooltip surfaces: bg-popover text-popover-foreground — avoids white-on-white in light mode.

Animation → animation.md

• Default duration ~1100ms for cartesian enter animations unless the doc specifies otherwise.
• Replay: change revealSignature or remount with a new key.
• Live charts: use paused on LiveLineChart to debug without stopping the rAF loop manually.

Tooltips → tooltips.md

• Custom content via ChartTooltip content prop or children patterns from docs.
• indicatorColor function for candlestick / dynamic crosshair colors.
• Custom indicators: use useChart() — do not track mouse globally outside chart context.

Installation → installation.md

• Require @bklit registry in components.json.
• Install: npx shadcn@latest add @bklit/<slug>.
• Let the CLI install peer dependencies — do not pin @visx/* / motion manually unless resolving a conflict.

Workflow

1. Run npx shadcn@latest info --json — verify @bklit registry and aliases.
2. Pick a chart from the catalog (or ask the user what story the data tells).
3. Open the doc URL for data shape and props.
4. If not installed: npx shadcn@latest add @bklit/<slug>.
5. Compose with grid, series, axes, tooltip — apply theming tokens.
6. Point the user to the gallery or Studio URL for variant inspiration.
