Elegant terminal spinner
npm install oraCheck out yocto-spinner for a smaller alternative.
import ora from 'ora';
const spinner = ora('Loading unicorns').start();
setTimeout(() => {
spinner.color = 'yellow';
spinner.text = 'Loading rainbows';
}, 1000);If a string is provided, it is treated as a shortcut for options.text.
Type: object
Type: string
The text to display next to the spinner.
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.
Type: string | () => string
Text or a function that returns text to display after the spinner text. No suffix text will be displayed if set to an empty string.
Type: string | object
Default: 'dots' 
The name of one of the provided spinners. See example.js in this repo if you want to test out different spinners. On Windows (except for Windows Terminal), it will always use the line spinner as the Windows command-line doesn't have proper Unicode support.
Or an object like:
{
frames: ['-', '+', '-'],
interval: 80 // Optional
}Type: string
Default: 'cyan'
Values: 'black' | 'red' | 'green' | 'yellow' | 'blue' | 'magenta' | 'cyan' | 'white' | 'gray'
The color of the spinner.
Type: boolean
Default: true
Set to false to stop Ora from hiding the cursor.
Type: number
Default: 0
Indent the spinner with the given number of spaces.
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.
Type: stream.Writable
Default: process.stderr
Stream to write the output.
You could for example set this to process.stdout instead.
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.
Type: boolean
Default: false
Disable the spinner and all log text. All output is suppressed and isEnabled will be considered false.
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 is no good way to implement discarding stdin properly there.

Change the text before the spinner.

Starts a spinner for a promise or promise-returning function. The spinner is stopped with .succeed() if the promise fulfills or with .fail() if it rejects. Returns the promise.
import {oraPromise} from 'ora';
await oraPromise(somePromise);Type: Promise | ((spinner: ora.Ora) => Promise)
Type: object
All of the options plus the following:
Type: string | ((result: T) => string) | undefined
The new text of the spinner when the promise is resolved.
Keeps the existing text if undefined.
Type: string | ((error: Error) => string) | undefined
The new text of the spinner when the promise is rejected.
Keeps the existing text if undefined.
Type: Record<string, Spinner>
All provided spinners.
Use chalk or yoctocolors:
import ora from 'ora';
import chalk from 'chalk';
const spinner = ora(`Loading ${chalk.red('unicorns')}`).start();JavaScript is single-threaded, so any synchronous operations will block the spinner's animation. To avoid this, prefer using asynchronous operations.
