想要在前端项目中压缩图片然后再上传到后端保存就需要一个压缩工具的帮助暂时有两个依赖库可以选择image-conversion和yireen/squoosh-browser看了官方仓库地址和更新时间等详情发现还是yireen/squoosh-browser最新一些所以就选择了yireen/squoosh-browser。
yireen/squoosh-browser地址yireen/squoosh-browser - npm
yireen/squoosh-browsergithub地址GitHub - myeveryheart/squoosh-browser: An image compression tool run in browser while squoosh/lib can not.
image-conversion地址image-conversion - npm 安装
执行命令
pnpm install yireen/squoosh-browser 使用
创建一个工具文件然后添加下面内容
import Compress from yireen/squoosh-browser
import {defaultPreprocessorState,defaultProcessorState,encoderMap,EncoderState
} from yireen/squoosh-browser/dist/client/lazy-app/feature-meta/*** 图片压缩编码器枚举*/
export enum CompressEncoderEnum {// eslint-disable-next-line no-unused-varsmozJPEG mozJPEG,// eslint-disable-next-line no-unused-varsavif avif,// eslint-disable-next-line no-unused-varswebP webP
}/*** 判断文件类型是否为图片格式* param fileType*/
export const isImage (fileType: string): boolean {return /(png|jpg|jpeg|gif|webp|awebp|avif|svg\xml|svg|x-icon|vnd.microsoft.icon)$/.test(fileType)
}/*** 判断是否需要压缩的图片格式* param imageType*/
export const isNeedCompress (imageType: string): boolean {return /(png|jpg|jpeg|webp|avif)$/.test(imageType)
}/*** 压缩图片* param file* param encoder*/
export const compressImage async (file: File, encoder: CompressEncoderEnum) {if (isNeedCompress(file.type)) {const compress new Compress(file, {encoderState: {type: encoder,options: encoderMap[encoder].meta.defaultOptions} as EncoderState,processorState: defaultProcessorState,preprocessorState: defaultPreprocessorState})return compress.process()}return file
}
