Anatomy

Import all parts and piece them together.

<script setup lang="ts">
import * as image from '@destyler/image'
import { normalizeProps, useMachine } from '@destyler/vue'
import { computed, useId } from 'vue'


const [state, send] = useMachine(image.machine({ id: useId() }))


const api = computed(() => image.connect(state.value, send, normalizeProps))
</script>


<template>
  <div v-bind="api.getRootProps()">
    <img v-bind="api.getImageProps()" >
    <div v-bind="api.getFallbackProps()" ></div>
  </div>
</template>
import * as image from '@destyler/image'
import { normalizeProps, useMachine } from '@destyler/react'
import { useId } from 'react'


export default function Image() {
  const [state, send] = useMachine(image.machine({
    id: useId(),
  }))


  const api = image.connect(state, send, normalizeProps)


  return (
    <div {...api.getRootProps()}>
      <img {...api.getImageProps()}/>
      <div {...api.getFallbackProps()}></div>
    </div>
  )
}
<script lang="ts">
  import * as image from '@destyler/image'
  import { normalizeProps, useMachine } from '@destyler/svelte'


  const id = $props.id()


  const [state, send] = useMachine(image.machine({ id }))


  const api = $derived(image.connect(state, send, normalizeProps))
</script>


<div {...api.getRootProps()}>
  <img {...api.getImageProps()} />
  <div {...api.getFallbackProps()} ></div>
</div>
import * as image from '@destyler/image'
import { normalizeProps, useMachine } from '@destyler/solid'
import { createMemo, createUniqueId } from 'solid-js'


export default function Image() {
  const [state, send] = useMachine(image.machine({
    id: createUniqueId(),
  }))


  const api = createMemo(() => image.connect(state, send, normalizeProps))


  return (
    <div {...api().getRootProps()}>
      <img {...api().getImageProps()}/>
      <div {...api().getFallbackProps()} ></div>
    </div>
  )
}

Listening for loading status changes

When the image has loaded or failed to load, the onStatusChange callback is invoked.

const [state, send] = useMachine(
  avatar.machine({
    onStatusChange(details) {
      // details => { status: "error" | "loaded" }
    },
  }),
)

Styling guide

Earlier, we mentioned that each avatar part has a data-part attribute added to them to select and style them in the DOM.

[data-scope="avatar"][data-part="root"] {
  /* Styles for the root part */
}


[data-scope="avatar"][data-part="image"] {
  /* Styles for the image part */
}


[data-scope="avatar"][data-part="fallback"] {
  /* Styles for the fallback part */
}

Methods and Properties

Machine Context

The image machine exposes the following context properties:

onStatusChange
(details: StatusChangeDetails) => void
Functional called when the image loading status changes.
ids
Partial<{ root: string; image: string; fallback: string; }>
The ids of the elements in the avatar. Useful for composition.
id
string
The unique identifier of the machine.
getRootNode
() => ShadowRoot | Node | Document
A root node to correctly resolve document in custom environments. E.x.: Iframes, Electron.
dir (default: "ltr")
"ltr" | "rtl"
The document's text/writing direction.

The image api exposes the following methods:

loaded
boolean
