用法

¥Usage

TypeScript

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

const text = ref('')

const { base64 } = useBase64(text)

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

如果你使用对象、数组、映射或集合，你可以在选项中提供序列化器。否则，你的数据将由默认序列化器序列化。对象和数组将通过 JSON.stringify 转换为字符串。 =在 stringify 之前，Map 和 Set 会分别转换为对象和数组。

¥If you use object, array, map or set you can provide serializer in options. Otherwise, your data will be serialized by default serializer. Objects and arrays will be transformed in string by JSON.stringify. Map and set will be transformed in object and array respectively before stringify.
