API

ora(text)

ora(options)

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.

prefixText

Type: string | () => string

Text or a function that returns text to display before the spinner. No prefix text will be displayed if set to an empty string.

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. On Windows, it will always use the line spinner as the Windows command-line doesn't have proper Unicode support.

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.

indent

Type: number
Default: 0

Indent the spinner with the given number of spaces.

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: stream.Writable
Default: process.stderr

Stream to write the output.

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

isEnabled

Type: boolean

Force enable/disable the spinner. If not specified, the spinner will be enabled if the stream is being run inside a TTY context (not spawned or piped) and/or not in a CI environment.

Note that {isEnabled: false} doesn't mean it won't output anything. It just means it won't output the spinner, colors, and other ansi escape codes. It will still log text.

isSilent

Type: boolean
Default: false

Disable the spinner and all log text. All output is suppressed and isEnabled will be considered false.

discardStdin

Type: boolean
Default: true

Discard stdin input (except Ctrl+C) while running if it's TTY. This prevents the spinner from twitching on input, outputting broken lines on Enter key presses, and prevents buffering of input while the spinner is running.

This has no effect on Windows as there's no good way to implement discarding stdin properly there.

FAQ

How do I change the color of the text?

Use Chalk:

const ora = require('ora');
const chalk = require('chalk');

const spinner = ora(`Loading ${chalk.red('unicorns')}`).start();

Why does the spinner freeze?

JavaScript is single-threaded, so synchronous operations blocks the thread, including the spinner animation. Prefer asynchronous operations whenever possible.
