In JSZip, you can list files inside a ZIP archive using zip.fileswhich is an Object with key = filename and value = file metadata object.
JSZip.loadAsync(fileContent).then(function(zip) {
for(let [filename, file] of Object.entries(zip.files)) {
// TODO Your code goes here
console.log(filename);
}
}).catch(function(err) {
console.error("Failed to open", filename, " as ZIP file:", err);
})Full example
