How do I zip and download all the files (keeping the folder structure) from a document library using Jsom and jzip Library?
Download multiple files then compress to one zip file using JSZip & JSZip-utils generate a single zip with multiple files with in multiple folder.from the code below I am able generate each zip for each folder with in a document library i want a single zip for all the folders
You could consider the following solution:
getBinaryContent(path, callback) from JSZipUtils to load
file content by file urlExample
loadFiles("Documents/2013",
function(files) {
var zip = new JSZip();
zipFiles(zip,files,0,function(content){
console.log('Done.');
saveAs(content, "archive.zip");
});
},
function(sender,args){
console.log(args.get_message());
}
);
where
function zipFiles(zip,files,index,complete){
index = index || 0;
var curFile = files.get_item(index);
JSZipUtils.getBinaryContent(curFile.get_serverRelativeUrl(), function (err, data) {
if(err) {
throw err; // or handle the error
}
zip.file(curFile.get_name(), data, {binary:true});
index++;
if(index < files.get_count()) {
zipFiles(zip,files,index,complete);
}
else {
zip.generateAsync({type:"blob"})
.then(function(content) {
complete(content);
});
}
});
}
function loadFiles(folderUrl,success,error){
var ctx = SP.ClientContext.get_current();
var web = ctx.get_web();
var folder = web.getFolderByServerRelativeUrl(folderUrl);
var files = folder.get_files();
ctx.load(files);
ctx.executeQueryAsync(
function() {
success(files);
},
error);
}

It isn't clear what version you are using from your question. Microsoft just announced this feature is coming with the modern SharePoint libraries in Office 365.

I put this together that will let you zip an array of image urls.

You can manage zip folder structure by modifying this line
filename = filename.replace(/[\/\*\|\:\<\>\?\"\\]/gi, '').replace("httpsi.imgur.com","");
//_spBodyOnLoadFunctionNames.push("AddZipIcon" );
function AddZipIcon() {
// for SP online
$(".ms-qcb-root ul li:nth-child(3)" ).each(function () {
$(this).first().before('<li class=" ms-qcb-item" >' +
'<a class=" ms-qcb-button ms-qcb-buttons-alignmentfix js-listview-qcbUploadButton js-callout-body js-qcb-button ms-qcb-glyph" type=" button" ' +
'title=" Select files and download as a zip file" accesskey=" z" onclick=" ConvertToZip()" ><span class=" ms-qcb-glyph ms-listview-glyph-withmargin ms-listview-sync-glyph ms-core-form-heading" ><img style=" height:20px;width:25px;" src="https://" /></span><span class=" ms-qcb-glyph ">Zip</span></a></li>')
});
}
function CheckDownloadZip()
{
return true;
}
function ConvertToZip()
{
var seldocs = GetSelectedItemsDocsURLs();
if(seldocs != null)
{
var dialog = SP.UI.ModalDialog.showWaitScreenWithNoClose('Creating Zip with selected files', 'Please wait while the files are added to zip...');
// alert("packaging..");
DownloadPackage(seldocs);
dialog.close(0);
}
}
function GetSelectedItemsDocsURLs()
{
var tempurls = [];
var items = SP.ListOperation.Selection.getSelectedItems(ctx);
if (items.length== 0) {
alert("Please select an item from the list" );
return null;
}
else
{
for (var i in items)
{
var getFileName = _spPageContextInfo.webAbsoluteUrl + "/_api/web/lists('" + SP.ListOperation.Selection.getSelectedList()+ "')/items(" + items[i].id + ")/?$select=EncodedAbsUrl" ;
$.ajax({
url: getFileName,
type: "GET" ,
headers: {
"accept" : "application/json;odata=verbose"
},
success: function (listData) {
tempurls.push(listData.d.EncodedAbsUrl);
// filename = fileURL.substr(fileURL.lastIndexOf('/') + 1);
},
error: function (error) {
console.log(JSON.stringify(error))

async: false

return tempurls;
