It is possible to use Svelte's draw
transition with a dynamically generated d
attribute of an SVG path. The key is to use Svelte's $:
reactive declarations to update the path's d
attribute whenever the function's output changes.
For example, let's say you have a function called getPath
that generates the d
attribute based on some input. Here's how you can use it with Svelte's draw
transition:
<script>
import { draw } from 'svelte/transition';
let input = '';
$: pathD = getPath(input); // dynamically generate path's d attribute
function getPath(input) {
// some code to generate the path's d attribute based on input
}
</script>
<svg width="100" height="100">
<path d={pathD} transition:draw={{ duration: 1000 }} />
</svg>
In this example, we use a reactive declaration $: pathD = getPath(input)
to update the pathD
variable whenever input
changes. We then pass the pathD
variable as the d
attribute of the path
element.
Finally, we add the transition:draw
directive to the path
element to animate its drawing based on the changes to the d
attribute. We can pass options to the draw
transition to control its duration and easing.
