Custom messages

Use the starting-message, success-message, and error-message attributes to customize the messages.

Download

<sl-file-download target-url="/" save-as-filename="home" id="example-2" starting-message="Here we go!" success-message="Oh yeah!!!" error-message="Oh no!!!!"></sl-file-download>

Timestamp on saved file name
