|

|
|
```js

|
|
|
|

|
|
|
|

|
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`<br>
|
|
Default: `false`
|
|
|
|
Force enabling of the spinner regardless of the `stream` not being run inside a TTY context and/or in a CI environment.
|
|
|
|
