Plotly.js for Svelte
This is an unofficial package that lets you efficiently use plotly.js inside your Svelte or SvelteKit app.
Usage
- Install using
yarn add svelte-plotly.jsornpm install svelte-plotly.js. - Choose a Plotly distribution:
- If you want to use
plotly.js-dist, just install it. - If you want to use a different distribution, take a look at this section.
- If you want to use
- Use in your app:
<script lang="ts">
import Plot from 'svelte-plotly.js';
const data = [
{
x: [1, 2, 3, 4, 5],
y: [1, 2, 4, 8, 16]
}
];
</script>
<Plot
{data}
layout={{
margin: { t: 0 }
}}
fillParent='width'
debounce={250}
/>
Custom Plotly distribution
Let's say you want to use svelte-plotly.js with a custom Plotly.js distribution, for example plotly.js-basic-dist-min. If you use Vite for bundling, the recommended way to do this would be to install plotly.js-basic-dist-min and then register it as an alias for plotly.js-dist by adding the following to your vite.config.js:
resolve: {
alias: {
"plotly.js-dist": "plotly.js-basic-dist-min",
lodash: "lodash-es",
},
},
If you don't use Vite, or this approach doesn't work for you, you can also use the libPlotly prop of the Plotly component:
<script lang="ts">
import Plot from 'svelte-plotly.js';
import libPlotly from 'plotly.js-basic-dist-min';
</script>
<Plot {libPlotly} ... />
