Angular 2 encode image to base64

Question

I want to encode the uploaded files to base64 so that I can pass them to the request. The problem is that I\'m using Angular 2 with Typescript and I couldn\'t find any info

Answer 1

So I find the solution:

compontent.ts

changeListener($event) : void {
  this.readThis($event.target);
}

readThis(inputValue: any): void {
  var file:File = inputValue.files[0];
  var myReader:FileReader = new FileReader();

  myReader.onloadend = (e) => {
    this.image = myReader.result;
  }
  myReader.readAsDataURL(file);
}

component.html
