使い方

import { QrCode } from "@yamada-ui/react"

import { QrCode } from "@/components/ui"

import { QrCode } from "@workspaces/ui"

<QrCode.Root>
  <QrCode.Frame>
    <QrCode.Pattern />
  </QrCode.Frame>
  <QrCode.Overlay />
</QrCode.Root>

サイズを変更する

<VStack>
  <For each={["2xs", "xs", "sm", "md", "lg", "xl", "2xl", "3xl", "4xl"]}>
    {(size, index) => (
      <QrCode.Root key={index} size={size} value="https://yamada-ui.com" />
    )}
  </For>
</VStack>

カラースキームを変更する

<Wrap gap="md">
  <For each={["red", "orange"]}>
    {(colorScheme, index) => (
      <QrCode.Root
        key={index}
        colorScheme={colorScheme}
        value="https://yamada-ui.com"
      />
    )}
  </For>
</Wrap>

色を変更する

<Wrap gap="md">
  <For each={["blue", "green"]}>
    {(color, index) => (
      <QrCode.Root key={index} color={color} value="https://yamada-ui.com" />
    )}
  </For>
</Wrap>

エラー修正レベルを変更する

エラー修正レベルを変更する場合は、eccにL、M、Q、Hを設定します。

<Wrap gap="md">
  <For each={["L", "M", "Q", "H"]}>
    {(ecc, index) => (
      <QrCode.Root key={index} ecc={ecc} value="https://yamada-ui.com" />
    )}
  </For>
</Wrap>

オーバーレイを使う

QrCode.Overlayを使うことで、QRコード上にアイコンなどを配置できます。

<QrCode.Root size="xl" value="https://yamada-ui.com">
  <QrCode.Frame>
    <QrCode.Pattern />
  </QrCode.Frame>

  <QrCode.Overlay>
    <Icon boxSize="14" color="currentColor" viewBox="0 0 196 196">
