Answer 1

I used event maxfilesexceeded with method addFile and rans into infinite loop of event call. It should be the problem of using addFile because I didn't see it mentioned in both official site or GitHub wiki. Finally I solved with addedfile event. The Dropzone.js is the latest version when I write (4.3.0).

init: function() {
  this.on('addedfile', function(file) {
    if (this.files.length > 1) {
      this.removeFile(this.files[0]);
    }
  });
}
