Squoosh && Sharp && Svgo

Unplugin-imagemin supports two compression modes

Sharp The typical use case for this high speed Node.js module is to convert large images in common formats to smaller, web-friendly JPEG, PNG, WebP, GIF and AVIF images of varying dimensions.

Squoosh is an image compression web app that reduces image sizes through numerous formats. Squoosh with rust & wasm

Svgo Support compression of pictures in svg format

✨Warning

Although squoosh has done a good job, there will be all kinds of problems in future node versions, so don't use squoosh mode for the time being.

Due to the loading problem of squoosh, unplugin-imagmin currently only supports versions below node 18.

Due to the rapid update of vite version and squoosh stop maintenance and other unstable factors

It is recommended that mode choose sharp.
