API

This library follows a non-error-throwing philosophy. If you provide an invalid option or an invalid value for a valid option it will be ignored.

Initialization:

new Spinnies([options])

Parameters

• options - object:

  • color - string: Any valid chalk color. The default value is white.

  • succeedColor - string: Any valid chalk color. The default value is green.

  • failColor - string: Any valid chalk color. The default value is red.

  • spinnerColor - string: Any valid chalk color. The default value is greenBright.

  • succeedPrefix - string: The default value is ✓.

  • failPrefix- string: The default value is ✖.

  • spinner- object:

    • interval - number
    • frames - string[]

    You can see the already provided spinner here.

  • disableSpins - boolean: Disable spins (will still print raw messages).

Note: If you are working in any win32 platform, the default spin animation will be overriden. You can get rid of this defining a different spinner animation manually, or by using the integrated VSCode terminal or Windows Terminal.

Example:

const spinner = { interval: 80, frames: ['🍇', '🍈', '🍉', '🍋'] }
const spinnies = new Spinnies({ color: 'blue', succeedColor: 'green', spinner });
