How to use beforeUpload in assetManager?

[andykramer]

Hi,
for file size limitation reason, i would like to use the method beforeUpload of the assteManager.

How is the correct way to use this methode?

I try to use it like this:

var editor = grapesjs.init({
  assetManager: {
    multiUpload: true,
    beforeUpload: (files) => {
       console.log(files);
    },
  },
});

Thanks

You can return false in beforeUpload in order to cancel the upload.

Hello artf
I know, but beforeUpload is never called.
I try something like this:

assetManager: {
  multiUpload: true,
  beforeUpload: (files) => {
   console.log(files);
   var maxFilesize = 3300000;
   var errorMessage = "";
   var error = false;

   for (let i = 0; i < files.length; i++) {
     if (files[i].size > maxFilesize) {
       errorMessage += "Image: " + files[i].name + " is too large. (" + files[i].size + ")\n";
       error = true;
     }
   }
   if (!error) {
     return true;
   }
   alert(errorMessage);
   return false;
 },
},

But this does not work! not even "console.log(files)"

Did you configure properly the uploader or you're using the default embedAsBase64 option? In that case beforeUpload triggers only before the real upload of files.
