</p>
|
||||
|

|
||||
## Install
|
||||
|
||||
```
|
||||
$ npm install ora
|
||||
```
|
||||
|
||||
<a href="https://www.patreon.com/sindresorhus">
|
||||
<img src="https://c5.patreon.com/external/logo/become_a_patron_button@2x.png" width="160">
|
||||
</a>
|
||||
|
||||
|
||||
## 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 running 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.
|
||||
|
||||
##### hideCursor
|
||||
|
||||
Type: `boolean`<br>
|
||||
Default: `true`
|
||||
|
||||
Set to `false` to stop Ora from hiding the cursor.
|
||||
|
||||
##### 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 `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.
|
||||
|
||||

|
||||

|
||||
|

|
||||
<img src="screenshot-2.gif" width="480">
|
||||
|
||||
#### .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.
|
||||
|
||||
#### .color
|
||||
|
||||
Change the spinner color.
|
||||
|
||||
### ora.promise(action, [options|text])
|
||||
|
||||
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`
