Achieve File Upload Programmatically in Angular Uploader component

05 May 2021 / 1 minute to read

You can upload a file programmatically using upload method. The selected files data, get from getFilesData public method in uploader.

The upload method behaves differently based on its arguments.

If this method receives any files as arguments, those files only start to upload.
If it has no argument then all the selected files are will start to upload.
