# `@inquirer/expand`
|
||||
|
||||
Compact single select prompt. Every option is assigned a shortcut key, and selecting `h` will expand all the choices and their descriptions.

# Usage
|
||||
|
||||
```js
|
||||
import { expand } from '@inquirer/prompts';
|
||||
// Or
|
||||
// import expand from '@inquirer/expand';
|
||||
|
||||
const answer = await expand({
|
||||
message: 'Conflict on file.js',
|
||||
default: 'y',
|
||||
choices: [
|
||||
{
|
||||
key: 'y',
|
||||
name: 'Overwrite',
|
||||
value: 'overwrite',
|
||||
},
|
||||
{
|
||||
key: 'a',
|
||||
name: 'Overwrite this one and all next',
|
||||
value: 'overwrite_all',
|
||||
},
|
||||
{
|
||||
key: 'd',
|
||||
name: 'Show diff',
|
||||
value: 'diff',
|
||||
},
|
||||
{
|
||||
key: 'x',
|
||||
name: 'Abort',
|
||||
value: 'abort',
|
||||
},
|
||||
],
|
||||
});
|
||||
```
|
||||
|
||||
## Options
|
||||
|
||||
| Property | Type | Required | Description |
|
||||
| -------- | ----------------------- | -------- | ----------------------------------------------------------------------------------------- |
|
||||
| message | `string` | yes | The question to ask |
|
||||
| choices | `Choice[]` | yes | Array of the different allowed choices. The `h`/help option is always provided by default |
|
||||
| default | `string` | no | Default choices to be selected. (value must be one of the choices `key`) |
|
||||
| expanded | `boolean` | no | Expand the choices by default |
|
||||
| theme | [See Theming](#Theming) | no | Customize look of the prompt. |
|
||||
|
||||
`Separator` objects can be used in the `choices` array to render non-selectable lines in the choice list. By default it'll render a line, but you can provide the text as argument (`new Separator('-- Dependencies --')`). This option is often used to add labels to groups within long list of options.
|
||||
|
||||
### `Choice` object
|
||||
|
||||
The `Choice` object is typed as
|
||||
|
||||
```ts
|
||||
type Choice<Value> = {
|
||||
value: Value;
|
||||
name?: string;
|
||||
key: string;
|
||||
};
|
||||
```
|
||||
|
||||
Here's each property:
|
||||
|
||||
- `value`: The value is what will be returned by `await expand()`.
|
||||
- `name`: The string displayed in the choice list. It'll default to the stringify `value`.
|
||||
- `key`: The input the use must provide to select the choice. Must be a lowercase single alpha-numeric character string.
|
||||
|
||||
## Theming
|
||||
|
||||
You can theme a prompt by passing a `theme` object option. The theme object only need to includes the keys you wish to modify, we'll fallback on the defaults for the rest.
|
||||
|
||||
```ts
|
||||
type Theme = {
|
||||
prefix: string | { idle: string; done: string };
|
||||
spinner: {
|
||||
interval: number;
|
||||
frames: string[];
|
||||
};
|
||||
style: {
|
||||
answer: (text: string) => string;
|
||||
message: (text: string, status: 'idle' | 'done' | 'loading') => string;
|
||||
error: (text: string) => string;
|
||||
defaultAnswer: (text: string) => string;
|
||||
highlight: (text: string) => string;
|
||||
};
|
||||
};
|
||||
```
