svelte-chart-apex v0.1.0

Svelte Apex Charts

Create and update dynamic SVG charts in Svelte(Kit) using ApexCharts - demo

Quick-Start

pnpm add apexcharts svelte-chart-apex -D
npm i apexcharts svelte-chart-apex -D
# Bring your own ApexCharts library.
# It is listed as a peer dependency.

<script>
  import { renderChart } from 'svelte-chart-apex';

  /** @type {import('svelte-chart-apex').Chart} */
  const chart = {
    options: {
      // Provide your own ApexChars options.
      chart: { type: 'bar' },
      series: [{ name: 'sales', data: [5, 6, 13, 26] }],
      xaxis: { categories: [2020, 2021, 2022, 2023] }
    }
  };
</script>

<!-- After the chart is created, chart.ref and chart.node are set. -->
<!-- This allows all ApexCharts methods to be used. (e.g. dataURI) -->
<div use:renderChart={chart}></div>

<!-- When the <div> element is unmounted, the chart gets destroyed. -->

<button
  type="button"
  on:click={() => {
    // chart.node is also available, which points to the <div> element.
    chart.ref?.updateSeries([{ data: [7, 10, 20, 23] }]);
  }}
>
  Update Series
</button>

Features

Compared to the svelte-apexcharts library,

• Supports SvelteKit - no more window is not defined error.
• Supports TypeScript - be confident with the chart options.
• Provides the chart reference - all Apex methods can be used.

chart.ref?.updateOptions({ xaxis: { labels: { show: false } }, yaxis: { min: 20, max: 100 } });
chart.ref?.addXaxisAnnotation({ x: 40, label: { text: 'Lorem Ipsum' } });
// And many more. Reference the ApexCharts documentation.

Notes

The Chart Object

• Create a chart object and pass the reference as the action parameter.
• This is necessary to update and provide chart.ref and chart.node.

<div use:renderChart={chart}></div>

Server-Side Rendering

• ApexCharts does not support SSR, and the issue is marked as stale.
• This StackOverflow post shows other ways of handling SSR errors.
