File Input Component

Input

The Component has two main inputs, one for the accepted file types and the other for the display text, which are by default set to "*", and "Click or Drag to Upload a File" respectively.

  @Input('accepts') accepts : string = "*";
  @Input('displayText') displayText : string = "Click or Drag to Upload a File";

Alternatively the styling on the component can be passed in by means of an HTML inline style set as the following input:

  @Input("styles")
  styles: string =
    "height : 100px; width : 100%; padding : 20px;";

Outputs

The Component has two output events, the File Metadata as a File and the File Data as a Uint8Array, these must be handled by the parent component.

  @Output() fileMetaSet = new EventEmitter<File>();
  @Output() fileDataSet = new EventEmitter<Uint8Array>();

Parent Component

HTML

The Component should be included in the HTML for the parent component with an accepted file type and event handlers for the fileDataSetSet and fileMetaSetSet events.

<file-input [accepts]="'image/*'" (fileDataSet)="setfileDataSet($event)" (fileMetaSet)="setfileMetaSet($event)"></file-input>

  setfileMetaSet(event: File){
    this.fileMeta = event;
  }

  setfileDataSet(event: Uint8Array){
    this.fileData = event;
  }
