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
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.
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.
