## API
### 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.
##### prefixText
Type: `string`
Text to display before 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. 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`<br>
Default: `cyan`<br>
Values: `black` `red` `green` `yellow` `blue` `magenta` `cyan` `white` `gray`
Color of the spinner.
##### hideCursor
Type: `boolean`<br>
Default: `true`
Set to `false` to stop Ora from hiding the cursor.
##### indent
Type: `number`<br>
Default: `0`
Indent the spinner with the given number of spaces.
##### 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: `stream.Writable`<br>
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.
### 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.
#### .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`<br>
Default: `' '`
Symbol to replace the spinner with.
###### text
Type: `string`<br>
Default: Current `text`
Text to be persisted after the symbol
###### prefixText
Type: `string`<br>
Default: Current `prefixText`
Text to be persisted before the symbol.
