## Install
|
||||
|
||||
```
|
||||
$ npm install ora
|
||||
```
|
||||
|
||||
## Usage
|
||||
|
||||
```js
|
||||
const ora = require('ora');
|
||||
|
||||
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`](#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'` <img src="screenshot-spinner.gif" width="14">
|
||||
|
||||
Name of one of the [provided spinners](https://github.com/sindresorhus/cli-spinners/blob/main/spinners.json). 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:
|
||||
|
||||
```js
|
||||
{
|
||||
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 <kbd>Enter</kbd> 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](https://github.com/chalk/chalk):
|
||||
|
||||
```js
|
||||
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.
