+# useQRCode
+
+Wrapper for [`qrcode`](https://github.com/soldair/node-qrcode).
+
+## Install
+
+```bash
+npm i qrcode@^1
+```
+
+## Usage
+
+```ts
+import { useQRCode } from '@vueuse/integrations/useQRCode'
+
+// `qrcode` will be a ref of data URL

+
+or passing a `ref` to it, the returned data URL ref will change along with the source ref's changes.
+
+```ts
+import { useQRCode } from '@vueuse/integrations/useQRCode'
+import { shallowRef } from 'vue'
+
+const text = shallowRef('text-to-encode')
+const qrcode = useQRCode(text)
+```
+
+```html
+<input v-model="text" type="text" />
+<img :src="qrcode" alt="QR Code" />
+```
+
+## Type Declarations
+
+```ts
+/**
+ * Wrapper for qrcode.
+ *
+ * @see https://vueuse.org/useQRCode
+ * @param text
+ * @param options
+ */
+export declare function useQRCode(
+  text: MaybeRefOrGetter<string>,
+  options?: QRCode.QRCodeToDataURLOptions,
