README

ora-classic

Legacy mirror of the ora package before it switched to the pure ESM syntax in August 2021. I have decided to publish this as a separate package for those who are not ready to migrate, or explicitly need to use the classic syntax for compatibility reasons.

Elegant terminal spinner



Install

$ npm install ora-classic

Usage

const ora = require('ora-classic');

const spinner = ora('Loading unicorns').start();

setTimeout(() => {
    spinner.color = 'yellow';
    spinner.text = 'Loading rainbows';
}, 1000);

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.

Instance

.start(text?)

Start the spinner. Returns the instance. Set the current text if text is provided.

.stop()

Stop and clear the spinner. Returns the instance.

.succeed(text?)

Stop the spinner, change it to a green ✔ and persist the current text, or text if provided. Returns the instance. See the GIF below.

.fail(text?)

Stop the spinner, change it to a red ✖ and persist the current text, or text if provided. Returns the instance. See the GIF below.

.warn(text?)

Stop the spinner, change it to a yellow ⚠ and persist the current text, or text if provided. Returns the instance.

.info(text?)

Stop the spinner, change it to a blue ℹ and persist the current text, or text if provided. Returns the instance.

.isSpinning

A boolean of whether the instance is currently spinning.

.stopAndPersist(options?)

Stop the spinner and change the symbol or text. Returns the instance. See the GIF below.

options

Type: object

symbol

Type: string
Default: ' '

Symbol to replace the spinner with.

text

Type: string
Default: Current 'text'

Text to be persisted after the symbol

prefixText

Type: string
Default: Current prefixText

Text to be persisted before the symbol. No prefix text will be displayed if set to an empty string.

.clear()

Clear the spinner. Returns the instance.

.render()

Manually render a new frame. Returns the instance.

.frame()

Get a new frame.

.text

Change the text after the spinner.

.prefixText

Change the text before the spinner. No prefix text will be displayed if set to an empty string.

.color

Change the spinner color.

.spinner

Change the spinner.

.indent

Change the spinner indent.

ora.promise(action, text)

ora.promise(action, options)

Starts a spinner for a promise. The spinner is stopped with .succeed() if the promise fulfills or with .fail() if it rejects. Returns the spinner instance.

action

Type: Promise

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.

Disclaimer

This repository is a fork of the ora package for Node JS. It mirrors the final version (5.4.1, June 2021) before transitioning from the CommonJS syntax to ESM (6.0.0, August 2021). The original work is licensed under MIT and as such, I claim no personal copyright for this publishing. All credit should go to the original developer @sindresorhus.

I am not trying to promote this over the original package. Rather, I am encouraging freedom of choice between the classic 'CommonJS' syntax and the emerging 'ESM' syntax. I have published this as a separate package under a distinct name in order to help developers make informed decisions when managing their dependencies. If you are not ready to transition to ESM and don't want to have to tiptoe around ora's recent updates, you can download this instead.

This is only a legacy publication and not an official project. I have never worked directly on the 'ora' library. I have absolutely no affiliation with @sindresorhus as a developer, or any of their contributors. Since this is only a mirror of a previous version, I will not be actively maintaining this repository. However, I cannot guarantee that this will work in the future. If something does break, I will try my best to fix it. Hopefully we will have all transitioned to ESM by the time that does actually happen.
