File Upload

A component that is used to upload multiple files.

Anatomy

To set up the file upload component correctly, you'll need to understand its anatomy and how we name its parts.

Each part includes a data-part attribute to help identify them in the DOM.

Examples

Learn how to use the FileUpload component in your project. Let's take a look at the most basic example:

import { FileUpload } from '@ark-ui/react/file-upload'
import { FileIcon } from 'lucide-react'

export const Basic = () => {
  return (
    <FileUpload.Root maxFiles={5}>
      <FileUpload.Label>File Upload</FileUpload.Label>
      <FileUpload.Dropzone>Drag your file(s) here</FileUpload.Dropzone>
      <FileUpload.Trigger>Choose file(s)</FileUpload.Trigger>
      <FileUpload.ItemGroup>
        <FileUpload.Context>
          {({ acceptedFiles }) =>
            acceptedFiles.map((file) => (
              <FileUpload.Item key={file.name} file={file}>
                <FileUpload.ItemPreview type="image/*">
                  <FileUpload.ItemPreviewImage />
                </FileUpload.ItemPreview>
                <FileUpload.ItemPreview type=".*">
                  <FileIcon />
                </FileUpload.ItemPreview>
                <FileUpload.ItemName />
                <FileUpload.ItemSizeText />
                <FileUpload.ItemDeleteTrigger>X</FileUpload.ItemDeleteTrigger>
              </FileUpload.Item>
            ))
          }
        </FileUpload.Context>
      </FileUpload.ItemGroup>
      <FileUpload.HiddenInput />
    </FileUpload.Root>
  )
}

import { FileUpload } from '@ark-ui/solid/file-upload'
import { For } from 'solid-js'

export const Basic = () => (
  <FileUpload.Root maxFiles={5}>
    <FileUpload.Label>File Upload</FileUpload.Label>
    <FileUpload.Dropzone>Drag your file(s) here</FileUpload.Dropzone>
    <FileUpload.Trigger>Choose file(s)</FileUpload.Trigger>
    <FileUpload.ItemGroup>
      <FileUpload.Context>
        {(context) => (
          <For each={context().acceptedFiles}>
            {(file) => (
              <FileUpload.Item file={file}>
                <FileUpload.ItemPreview type="image/*">
                  <FileUpload.ItemPreviewImage />
                </FileUpload.ItemPreview>
                <FileUpload.ItemPreview type=".*">Any Icon</FileUpload.ItemPreview>
                <FileUpload.ItemName />
                <FileUpload.ItemSizeText />
                <FileUpload.ItemDeleteTrigger>X</FileUpload.ItemDeleteTrigger>
              </FileUpload.Item>
            )}
          </For>
        )}
      </FileUpload.Context>
    </FileUpload.ItemGroup>
    <FileUpload.HiddenInput />
  </FileUpload.Root>
)

<script setup lang="ts">
import { FileUpload } from '@ark-ui/vue/file-upload'
</script>

<template>
  <FileUpload.Root :maxFiles="5">
    <FileUpload.Label>File Upload</FileUpload.Label>
    <FileUpload.Dropzone>Drop your files here</FileUpload.Dropzone>
    <FileUpload.Trigger>Choose file(s)</FileUpload.Trigger>
    <FileUpload.ItemGroup>
      <FileUpload.Context v-slot="{ acceptedFiles }">
        <FileUpload.Item v-for="file in acceptedFiles" :file="file" :key="file.name">
          <FileUpload.ItemPreview type="image/*">
            <FileUpload.ItemPreviewImage />
          </FileUpload.ItemPreview>
          <FileUpload.ItemPreview type=".*">
            <div>Generic Icon</div>
          </FileUpload.ItemPreview>
          <FileUpload.ItemName />
          <FileUpload.ItemSizeText />
          <FileUpload.ItemDeleteTrigger>X</FileUpload.ItemDeleteTrigger>
        </FileUpload.Item>
      </FileUpload.Context>
    </FileUpload.ItemGroup>
    <FileUpload.HiddenInput />
  </FileUpload.Root>
</template>

Using the Field Component

The Field component helps manage form-related state and accessibility attributes of an file upload. It includes handling ARIA labels, helper text, and error text to ensure proper accessibility.

import { Field } from '@ark-ui/react/field'
import { FileUpload } from '@ark-ui/react/file-upload'

export const WithField = (props: Field.RootProps) => (
  <Field.Root {...props}>
    <FileUpload.Root maxFiles={5}>
      <FileUpload.Label>Label</FileUpload.Label>
      <FileUpload.Trigger>Select</FileUpload.Trigger>
      <FileUpload.ItemGroup />
      <FileUpload.HiddenInput data-testid="input" />
    </FileUpload.Root>
    <Field.HelperText>Additional Info</Field.HelperText>
    <Field.ErrorText>Error Info</Field.ErrorText>
  </Field.Root>
)

import { Field } from '@ark-ui/solid/field'
import { FileUpload } from '@ark-ui/solid/file-upload'

export const WithField = (props: Field.RootProps) => (
  <Field.Root {...props}>
    <FileUpload.Root maxFiles={5}>
      <FileUpload.Label>Label</FileUpload.Label>
      <FileUpload.Trigger>Select</FileUpload.Trigger>
      <FileUpload.ItemGroup />
      <FileUpload.HiddenInput data-testid="input" />
    </FileUpload.Root>
    <Field.HelperText>Additional Info</Field.HelperText>
    <Field.ErrorText>Error Info</Field.ErrorText>
  </Field.Root>
)

<script setup lang="ts">
import { Field } from '@ark-ui/vue/field'
import { FileUpload } from '@ark-ui/vue/file-upload'
</script>

<template>
  <Field.Root>
    <FileUpload.Root :maxFiles="5">
      <FileUpload.Label>Label</FileUpload.Label>
      <FileUpload.Trigger>Select</FileUpload.Trigger>
      <FileUpload.ItemGroup />
      <FileUpload.HiddenInput data-testid="input" />
    </FileUpload.Root>
    <Field.HelperText>Additional Info</Field.HelperText>
    <Field.ErrorText>Error Info</Field.ErrorText>
  </Field.Root>
</template>
