I have following scenario: I have an component here:
<div class="border shadow p-2">
<chart :config="barConfig" ref="linechart" />
</div>
Now i can access it like this:
let linechart = ref(null)
The thing is, linechart
is not just a normal HTML element. Usuall i would do something like:
let linechart = ref<HTMLElement>()
But its actually an component. I can access the methods from it with
linechart.value.update()
But typescript throws me an error that update()
does not exist. I have tried this:
import chart from "@/components/chart/chart.vue";
let linechart = ref<typeof chart>();
linechart.value.update();
But still no luck. Is there a way to get the exposed methods without an typescript error?
To be clear, the .update()
method works. Its just typescript that cannot find the method. How do i fix it?
I found it out. Its actually written in the docs.
https://vuejs.org/guide/typescript/composition-api.html#typing-component-template-refs
This works perfect:
import chart from "@/components/chart/chart.vue";
let linechart = ref<InstanceType<typeof chart>>();
linechart.value?.update();
