# Usage
|
||||
|
||||
```js
|
||||
import { select, Separator } from '@inquirer/prompts';
|
||||
// Or
|
||||
// import select, { Separator } from '@inquirer/select';
|
||||
|
||||
const answer = await select({
|
||||
message: 'Select a package manager',
|
||||
choices: [
|
||||
{
|
||||
name: 'npm',
|
||||
value: 'npm',
|
||||
description: 'npm is the most popular package manager',
|
||||
},
|
||||
{
|
||||
name: 'yarn',
|
||||
value: 'yarn',
|
||||
description: 'yarn is an awesome package manager',
|
||||
},
|
||||
new Separator(),
|
||||
{
|
||||
name: 'jspm',
|
||||
value: 'jspm',
|
||||
disabled: true,
|
||||
},
|
||||
{
|
||||
name: 'pnpm',
|
||||
value: 'pnpm',
|
||||
disabled: '(pnpm is not available)',
|
||||
},
|
||||
],
|
||||
});
|
||||
```
|
||||
|
||||
## Options
|
||||
|
||||
| Property | Type | Required | Description |
|
||||
| -------- | ----------------------- | -------- | ------------------------------------------------------------------------------------------------------------------------------------------- |
|
||||
| message | `string` | yes | The question to ask |
|
||||
| choices | `Choice[]` | yes | List of the available choices. |
|
||||
| default | `string` | no | Defines in front of which item the cursor will initially appear. When omitted, the cursor will appear on the first selectable item. |
|
||||
| pageSize | `number` | no | By default, lists of choice longer than 7 will be paginated. Use this option to control how many choices will appear on the screen at once. |
|
||||
| loop | `boolean` | no | Defaults to `true`. When set to `false`, the cursor will be constrained to the top and bottom of the choice list without looping. |
|
||||
| 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;
|
||||
description?: string;
|
||||
short?: string;
|
||||
disabled?: boolean | string;
|
||||
};
|
||||
```
|
||||
|
||||
Here's each property:
|
||||
|
||||
- `value`: The value is what will be returned by `await select()`.
|
||||
- `name`: This is the string displayed in the choice list.
|
||||
- `description`: Option for a longer description string that'll appear under the list when the cursor highlight a given choice.
|
||||
- `short`: Once the prompt is done (press enter), we'll use `short` if defined to render next to the question. By default we'll use `name`.
|
||||
- `disabled`: Disallow the option from being selected. If `disabled` is a string, it'll be used as a help tip explaining why the choice isn't available.
|
||||
|
||||
`choices` can also be an array of string, in which case the string will be used both as the `value` and the `name`.
|
||||
|
||||
## 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;
|
||||
help: (text: string) => string;
|
||||
highlight: (text: string) => string;
|
||||
description: (text: string) => string;
|
||||
disabled: (text: string) => string;
|
||||
keysHelpTip: (keys: [key: string, action: string][]) => string | undefined;
|
||||
};
|
||||
icon: {
|
||||
cursor: string;
|
||||
};
|
||||
indexMode: 'hidden' | 'number';
|
||||
};
|
||||
```
|
||||
|
||||
### `theme.style.keysHelpTip`
|
||||
|
||||
This function allows you to customize the keyboard shortcuts help tip displayed below the prompt. It receives an array of key-action pairs and should return a formatted string. You can also hook here to localize the labels to different languages.
|
||||
|
||||
It can also returns `undefined` to hide the help tip entirely. This is the replacement for the deprecated theme option `helpMode: 'never'`.
|
||||
|
||||
```js
|
||||
theme: {
|
||||
style: {
|
||||
keysHelpTip: (keys) => {
|
||||
// Return undefined to hide the help tip completely.
|
||||
return undefined;
|
||||
|
||||
// Or customize the formatting. Or localize the labels.
|
||||
return keys.map(([key, action]) => `${key}: ${action}`).join(' | ');
|
||||
};
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### `theme.indexMode`
|
||||
|
||||
Controls how indices are displayed before each choice:
|
||||
|
||||
- `hidden` (default): No indices are shown
|
||||
- `number`: Display a number before each choice (e.g. "1. Option A")
