How to upload image instantly via FilePond

I want to make a program that takes a number of photos from the user. And every photo will be uploaded to the server as soon as it is selected. How can I do this?

<script>
    FilePond.registerPlugin(
      FilePondPluginImagePreview
    );

    $('.fileUpload').filepond({
        allowDrop: true,
        allowBrowse: true,
        allowMultiple: true,
        allowReplace: true,
        allowRevert: true,
        allowRemove: true,
        allowProcess: true,
        maxFiles: 15,
        maxParallelUploads: 1,
        itemInsertLocation: 'before',
        dropOnElement: true,
        dropValidation: true,
        instantUpload: true,
        server: {
            url: './',
            timeout: 0,
            process: {
                url: 'api/UploadPictures/Upload',
                method: 'POST',
            },
            revert: null,
            restore: null,
            load: null,
            fetch: null,
        }
    });
</script>
