*Show your support for Ora by buying this excellent [Node.js course](https://LearnNode.com/friend/AWESOME).*
## Usage
```js
const ora = require('ora');
const spinner = ora('Loading unicorns').start();
setTimeout(() => {
spinner.color = 'yellow';
spinner.text = 'Loading rainbows';
}, 1000);
```
## API
It will gracefully not do anything when there's no TTY or when in a CI.
### ora([options|text])
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.
##### spinner
Type: `string` `Object`<br>
Default: `dots` <img src="screenshot-spinner.gif" width="14">
Name of one of the [provided spinners](https://github.com/sindresorhus/cli-spinners/blob/master/spinners.json). See `example.js` in this repo if you want to test out different spinners.
Or an object like:
```js
{
interval: 80, // optional
frames: ['-', '+', '-']
}
```
##### color
Type: `string`<br>
Default: `cyan`<br>
Values: `black` `red` `green` `yellow` `blue` `magenta` `cyan` `white` `gray`
Color of the spinner.
##### interval
Type: `number`<br>
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: `WritableStream`<br>
Default: `process.stderr`
Stream to write the output.
You could for example set this to `process.stdout` instead.
##### enabled
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.
### 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 `` and persist the current text, or `text` if provided. Returns the instance.
#### .stopAndPersist([options])

##### options
Type: `Object`
###### symbol
Type: `string`<br>
