Best a way to uplaod zip file using ionic? Ionic 2 or 3

Question

Should upload zip file using ionic framework. But I'm not too good with ionic and this is my try:

 <ion-input type="file" formControlName="zipFiles" (change)="zipFilesUpload($event)"></ion-input>

and in ts:

  zipFilesUpload(event) {
    console.log(event)
    this.zipFiles = <File>event.target.files[0];
  }

Is this enough? Will this work on ionic? is there a better way?

How do I upload a file to the server now?

I've googled some solutions but I can't find anything acceptable. I don't need to unzip the file just to send.
