响应式的 Base64 转换。支持 plain text，buffer，files，canvas，objects，maps，sets 和 images。

示例

源码

文本输入

Base64

Buffer 输入

new ArrayBuffer(1024)

用法

TypeScript

import { useBase64 } from '@vueuse/core'
import { Ref, ref } from 'vue'

const text = ref('')

const { base64 } = useBase64(text)

import { useBase64 } from '@vueuse/core'
import { ref } from 'vue'
const text = ref('')
const { base64 } = useBase64(text)

如果你使用对象、数组、Map 或 Set，你可以在选项中提供序列化器。否则，你的数据将使用默认的序列化器进行序列化。对象和数组将通过 JSON.stringify 转换为字符串。Map 和 Set 将在转换为对象和数组之后再进行字符串化。
