使用Vue3实现在浏览器端进行zip文件压缩

npm install jszip

<script lang="ts" setup>
import { ref } from 'vue'
import JSZip from 'jszip'
import { saveAs } from 'file-saver' // 注意这里我假设你已经有file-saver库了

interface FileData {
  file: File
  fileName: string
}

const fileDatas = ref<FileData[]>([])
const isCompress = ref(false) // 是否启用压缩
const compressionLevel = ref(6) // 压缩级别
const packagingPercentage = ref(0) // 压缩进度

// 文件上传处理函数
const fileUpload = (file: File) => {
  fileDatas.value.push({
    file,
    fileName: file.name
  })
}

// 打包为zip文件
const packageAsZip = async () => {
  packagingPercentage.value = 0

  const zip = new JSZip()
  fileDatas.value.forEach((fileData) => {
    zip.file(fileData.fileName, fileData.file)
    packagingPercentage.value += 100 / fileDatas.value.length // 简化进度计算
  })

  let content: Blob

  if (isCompress.value) {
    content = await zip.generateAsync({
      type: 'blob',
      compression: 'DEFLATE',
      compressionOptions: { level: compressionLevel.value }
    })
  } else {
    content = await zip.generateAsync({ type: 'blob' })
  }

  saveAs(content, 'compressed_files.zip')
}
</script>
