Quick start

Installation:

pnpm add solid-chartjs chart.js
# or
yarn add solid-chartjs chart.js
# or
npm i solid-chartjs chart.js

Demo: solid-chartjs.vychs.com

Usage:

import { onMount } from 'solid-js'
import { Chart, Title, Tooltip, Legend, Colors } from 'chart.js'
import { Line } from 'solid-chartjs'

const MyChart = () => {
    /**
     * You must register optional elements before using the chart,
     * otherwise you will have the most primitive UI
     */
    onMount(() => {
        Chart.register(Title, Tooltip, Legend, Colors)
    })

    const chartData = {
        labels: ['January', 'February', 'March', 'April', 'May'],
        datasets: [
            {
                label: 'Sales',
                data: [50, 60, 70, 80, 90],
            },
        ],
    }
    const chartOptions = {
        responsive: true,
        maintainAspectRatio: false,
    }

    return (
        <div>
            <Line data={chartData} options={chartOptions} width={500} height={500} />
        </div>
    )
}

If you don't want to import and register the controllers, elements, scales, and plugins you want to use, you can use the following solution:

[!NOTE]
It is considered to better use the tree-shakable way, to decrease the bundle size.

import 'chart.js/auto'
import { DefaultChart } from 'solid-chartjs'

<DefaultChart type="line" data={data} options={options} />

Chart Props

Prop	Description	Type
width	The width of the chart canvas in pixels.	number | undefined
height	The height of the chart canvas in pixels.	number | undefined
fallback	A fallback element to display when chart fails.	JSX.Element
type	The type of the chart.	keyof ChartTypeRegistry
data	The chart data object.	ChartData | undefined
options	The chart options object.	ChartOptions | undefined
plugins	The chart plugins object.	Plugin[] | undefined

Examples

Check out /dev folder and run the SolidJs application to see how it works.

You can also use the DefaultChart components:

[!NOTE]
DefaultChart is a wrapper around Chart component, so you can use all the props from Chart component. DefaultChart component does not have its registrable elements registered by default, so you need to register them yourself unless you use chart.js/auto.

import { onMount } from 'solid-js'
import {
    Chart,
    LineController,
    CategoryScale,
    PointElement,
    LineElement,
    LinearScale,
} from 'chart.js'
import { DefaultChart } from 'solid-chartjs'

const MyChart = () => {
    onMount(() => {
        Chart.register(LineController, CategoryScale, PointElement, LineElement, LinearScale)
    })

    // ... your data and options objects

    return <DefaultChart type="line" data={data} options={options} width={400} height={300} />
}

Usage of fallback prop:

const fallback = () => {
    return (
        <div>
            <p>Chart is not available</p>
        </div>
    )
}

<DefaultChart type="bar" data={chartData} options={chartOptions} fallback={fallback} />
