API

It will gracefully not do anything when there's no TTY or when in a CI.

Spinner([options|text])

If a string is provided, it is treated as a shortcut for options.text.

options

Type: object

text

Type: string

Text to display after the spinner.

spinner

Type: string object
Default: dots

Name of one of the provided spinners. See example.js in this repo if you want to test out different spinners.

Or an object like:

{
	interval: 80, // optional
	frames: ['-', '+', '-']
}

color

Type: string
Default: cyan
Values: black red green yellow blue magenta cyan white gray

Color of the spinner.

hideCursor

Type: boolean
Default: true

Set to false to stop Ora from hiding the cursor.

interval

Type: number
Default: Provided by the spinner or 100

Interval between each frame.

Spinners provide their own recommended interval, so you don't really need to specify this.

stream

Type: WritableStream
Default: process.stderr

Stream to write the output.

You could for example set this to process.stdout instead.

enabled

Type: boolean
Default: false

Force enabling of the spinner regardless of the stream not being run inside a TTY context and/or in a CI environment.
