Fork from https://github.com/imagemin/imagemin-mozjpeg Repackage to support cjs and upgrade package dependencies Removed binary from the package so that you can link to the most updated binary yourself !!! You should install the mozjpeg library manually
You need to install mozjpeg in your system first !!!
$ npm install imagemin-mozjpeg
import imagemin from "imagemin";
import imageminMozjpeg from "imagemin-mozjpeg";
(async () => {
await imagemin(["images/*.jpg"], {
binaryPath: "/opt/homebrew/opt/mozjpeg/bin/cjpeg",
destination: "build/images",
plugins: [imageminMozjpeg()],
});
console.log("Images optimized");
})();
Returns a Promise<Buffer>
