API

The package is available by importing its default function:

import indicatrix from 'indicatrix'

async indicatrix(  text: string,  promise: !Promise<T>|function(...*): !Promise<T>,  options=: !Options,): T

Will print the loading text and refresh the CLI line to show the ellipsis while the promise is loading.

  • text* string: The text to display in the CLI.
  • promise (!Promise<T> | function(...): !Promise<T>): The promise or an async function that returns the promise.
  • options !Options (optional): The optional options for the indicator, such as the refresh interval.

When called from the CLI application, indicatrix will print the supplied text and draw the ellipsis (. > .. > ... > .) animation at the end, until the promise is resolved.
