Alpine Adapter

shell

pnpm add @tanstack/charts @tanstack/alpine-charts alpinejs d3-scale

import Alpine from 'alpinejs'
import { charts } from '@tanstack/alpine-charts'

Alpine.plugin(charts)
Alpine.start()

html

<div x-data="{ chartOptions }" x-chart="chartOptions"></div>

The directive element owns its contents. Alpine effects forward option changes to the shared host and directive cleanup destroys the runtime.

Lifecycle

charts registers x-chart. The directive evaluates its expression inside an Alpine effect, creates one shared adapter controller, and forwards each complete ChartOptions value. Cleanup destroys the controller, removes the surface, and restores the element's prior inline layout and host class.

Browser-only contract

The directive requires Alpine and normal DOM APIs. It does not prerender a server shell or provide a hydration path. Start it in the browser after registering Alpine.plugin(charts).

Presentation and rendering

The directive element itself becomes .ts-chart-host; normal HTML class and style attributes own its presentation. The className chart option applies to the rendered SVG surface. The package exposes the SVG directive only; use renderSvg to replace SVG serialization without replacing the shared host.

Exports: charts, ChartOptions, ChartTooltipBodyRenderContext, AlpineChartTooltipBody, ChartDefinition, and ChartPoint.

const chartOptions = {
  definition,
  ariaLabel: 'Revenue',
  renderTooltipBody({ points, defaultBody, pinned, dismiss }) {
    const body = document.createElement('div')
    body.append(defaultBody)
    body.append(`Focused rows: ${points.length}`)
    if (pinned) {
      const close = document.createElement('button')
      close.textContent = 'Close'
      close.addEventListener('click', dismiss)
      body.append(close)
    }
    return body
  },
