<b>Lightweight, beautiful and user-friendly interactive prompts</b><br />
|
|
|
<sub>>_ Easy to use CLI prompts to enquire users for information▌</sub>
|
|

|
<br />
|
|
|
|
|
|
* **Simple**: prompts has [no big dependencies](http://npm.anvaka.com/#/view/2d/prompts) nor is it broken into a [dozen](http://npm.anvaka.com/#/view/2d/inquirer) tiny modules that only work well together.
|
|
|
* **User friendly**: prompt uses layout and colors to create beautiful cli interfaces.
|
|
|
* **Promised**: uses promises and `async`/`await`. No callback hell.
|
|
|
* **Flexible**: all prompts are independent and can be used on their own.
|
|
|
* **Testable**: provides a way to submit answers programmatically.
|
|
|
* **Unified**: consistent experience across all [prompts](#-types).

## ❯ Examples
|
|
|
|
|
|
### Single Prompt
|
|
|
|
|
|
Prompt with a single prompt object. Returns an object with the response.
|
|
|
|
|
|
```js
|
|
|
const prompts = require('prompts');
|
|
|
|
|
|
(async () => {
|
|
|
const response = await prompts({
|
|
|
type: 'text',
|
|
|
name: 'meaning',
|
|
|
message: 'What is the meaning of life?'
|
|
|
});
|
|
|
|
|
|
console.log(response.meaning);
|
|
|
})();
|
|
|
```
|
|
|
|
|
|
### Prompt Chain
|
|
|
|
|
|
Prompt with a list of prompt objects. Returns an object with the responses.
|
|
|
Make sure to give each prompt a unique `name` property to prevent overwriting values.
|
|
|
|
|
|
```js
|
|
|
const prompts = require('prompts');
|
|
|
|
|
|
const questions = [
|
|
|
{
|
|
|
type: 'text',
|
|
|
name: 'username',
|
|
|
message: 'What is your GitHub username?'
|
|
|
},
|
|
|
{
|
|
|
type: 'number',
|
|
|
name: 'age',
|
|
|
message: 'How old are you?'
|
|
|
},
|
|
|
{
|
|
|
type: 'text',
|
|
|
name: 'about',
|
|
|
message: 'Tell something about yourself',
|
|
|
initial: 'Why should I?'
|
|
|
}
|
|
|
];
|
|
|
|
|
|
(async () => {
|
|
|
const response = await prompts(questions);
|
|
|
|
|
|
// => response => { username, age, about }
|
|
|
})();
|
|
|
```
|
|
|
|
|
|
### Dynamic Prompts
|
|
|
|
|
|
Prompt properties can be functions too.
|
|
|
Prompt Objects with `type` set to `falsy` values are skipped.
|
|
|
|
|
|
```js
|
|
|
const prompts = require('prompts');
|
|
|
|
|
|
const questions = [
|
|
|
{
|
|
|
type: 'text',
|
|
|
name: 'dish',
|
|
|
message: 'Do you like pizza?'
|
|
|
},
|
|
|
{
|
|
|
type: prev => prev == 'pizza' ? 'text' : null,
|
|
|
name: 'topping',
|
|
|
message: 'Name a topping'
|
|
|
}
|
|
|
];
|
|
|
|
|
|
(async () => {
|
|
|
const response = await prompts(questions);
|
|
|
})();
|
|
|
```
|
|
|

|
|
|
|
|
Type: `Function`<br>
|
|
|
Returns: `Object`
|
|
|
|
|
|
Prompter function which takes your [prompt objects](#-prompt-objects) and returns an object with responses.
|
|
|
|
|
|
|
|
|
#### prompts
|
|
|
|
|
|
Type: `Array|Object`<br>
|
|
|
|
|
|
Array of [prompt objects](#-prompt-objects).
|
|
|
These are the questions the user will be prompted. You can see the list of supported [prompt types here](#-types).
|
|
|
|
|
|
Prompts can be submitted (<kbd>return</kbd>, <kbd>enter</kbd>) or canceled (<kbd>esc</kbd>, <kbd>abort</kbd>, <kbd>ctrl</kbd>+<kbd>c</kbd>, <kbd>ctrl</kbd>+<kbd>d</kbd>). No property is being defined on the returned response object when a prompt is canceled.
|
|
|
|
|
|
#### options.onSubmit
|
|
|
|
|
|
Type: `Function`<br>
|
|
|
Default: `() => {}`
|
|
|
|
|
|
Callback that's invoked after each prompt submission.
|
|
|
Its signature is `(prompt, answer, answers)` where `prompt` is the current prompt object, `answer` the user answer to the current question and `answers` the user answers so far. Async functions are supported.
|
|
|
|
|
|
Return `true` to quit the prompt chain and return all collected responses so far, otherwise continue to iterate prompt objects.
|
|
|
|
|
|
**Example:**
|
|
|
```js
|
|
|
(async () => {
|
|
|
const questions = [{ ... }];
|
|
|
const onSubmit = (prompt, answer) => console.log(`Thanks I got ${answer} from ${prompt.name}`);
|
|
|
const response = await prompts(questions, { onSubmit });
|
|
|
})();
|
|
|
```
|
|
|
|
|
|
#### options.onCancel
|
|
|
|
|
|
Type: `Function`<br>
|
|
|
Default: `() => {}`
|
|
|
|
|
|
Callback that's invoked when the user cancels/exits the prompt.
|
|
|
Its signature is `(prompt, answers)` where `prompt` is the current prompt object and `answers` the user answers so far. Async functions are supported.
|
|
|
|
|
|
Return `true` to continue and prevent the prompt loop from aborting.
|
|
|
On cancel responses collected so far are returned.
|
|
|
|
|
|
**Example:**
|
|
|
```js
|
|
|
(async () => {
|
|
|
const questions = [{ ... }];
|
|
|
const onCancel = prompt => {
|
|
|
console.log('Never stop prompting!');
|
|
|
return true;
|
|
|
}
|
|
|
const response = await prompts(questions, { onCancel });
|
|
|
})();
|
|
|
```
|
|
|
|
|
|
### override
|
|
|
|
|
|
Type: `Function`
|
|
|
|
|
|
Preanswer questions by passing an object with answers to `prompts.override`.
|
|
|
Powerful when combined with arguments of process.
|
|
|
|
|
|
**Example**
|
|
|
```js
|
|
|
const prompts = require('prompts');
|
|
|
prompts.override(require('yargs').argv);
|
|
|
|
|
|
(async () => {
|
|
|
const response = await prompts([
|
|
|
{
|
|
|
type: 'text',
|
|
|
name: 'twitter',
|
|
|
message: `What's your twitter handle?`
|
|
|
},
|
|
|
{
|
|
|
type: 'multiselect',
|
|
|
name: 'color',
|
|
|
message: 'Pick colors',
|
|
|
choices: [
|
|
|
{ title: 'Red', value: '#ff0000' },
|
|
|
{ title: 'Green', value: '#00ff00' },
|
|
|
{ title: 'Blue', value: '#0000ff' }
|
|
|
],
|
|
|
}
|
|
|
]);
|
|
|
|
|
|
console.log(response);
|
|
|
})();
|
|
|
```
|
|
|
|
|
|
### inject(values)
|
|
|
|
|
|
Type: `Function`<br>
|
|
|
|
|
|
Programmatically inject responses. This enables you to prepare the responses ahead of time.
|
|
|
If any injected value is found the prompt is immediately resolved with the injected value.
|
|
|
This feature is intended for testing only.
|
|
|
|
|
|
#### values
|
|
|
|
|
|
Type: `Array`
|
|
|
|
|
|
Array with values to inject. Resolved values are removed from the internal inject array.
|
|
|
Each value can be an array of values in order to provide answers for a question asked multiple times.
|
|
|
If a value is an instance of `Error` it will simulate the user cancelling/exiting the prompt.
|
|
|
|
|
|
**Example:**
|
|
|
```js
|
|
|
const prompts = require('prompts');
|
|
|
|
|
|
prompts.inject([ '@terkelg', ['#ff0000', '#0000ff'] ]);
|
|
|
|
|
|
(async () => {
|
|
|
const response = await prompts([
|
|
|
{
|
|
|
type: 'text',
|
|
|
name: 'twitter',
|
|
|
message: `What's your twitter handle?`
|
|
|
},
|
|
|
{
|
|
|
type: 'multiselect',
|
|
|
name: 'color',
|
|
|
message: 'Pick colors',
|
|
|
choices: [
|
|
|
{ title: 'Red', value: '#ff0000' },
|
|
|
{ title: 'Green', value: '#00ff00' },
|
|
|
{ title: 'Blue', value: '#0000ff' }
|
|
|
],
|
|
|
}
|
|
|
]);
|
|
|
|
|
|
// => { twitter: 'terkelg', color: [ '#ff0000', '#0000ff' ] }
|
|
|
})();
|
|
|
```
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
## ❯ Prompt Objects
|
|
|
|
|
|
Prompts Objects are JavaScript objects that define the "questions" and the [type of prompt](#-types).
|
|
|
Almost all prompt objects have the following properties:
|
|
|
|
|
|
```js
|
|
|
{
|
|
|
type: String | Function,
|
|
|
name: String | Function,
|
|
|
message: String | Function,
|
|
|
initial: String | Function | Async Function
|
|
|
format: Function | Async Function,
|
|
|
onRender: Function
|
|
|
onState: Function
|
|
|
stdin: Readable
|
|
|
stdout: Writeable
|
|
|
}
|
|
|
```
|
|
|
|
|
|
Each property be of type `function` and will be invoked right before prompting the user.
|
|
|
|
|
|
The function signature is `(prev, values, prompt)`, where `prev` is the value from the previous prompt,
|
|
|
`values` is the response object with all values collected so far and `prompt` is the previous prompt object.
|
|
|
|
|
|
**Function example:**
|
|
|
```js
|
|
|
{
|
|
|
type: prev => prev > 3 ? 'confirm' : null,
|
|
|
name: 'confirm',
|
|
|
message: (prev, values) => `Please confirm that you eat ${values.dish} times ${prev} a day?`
|
|
|
}
|
|
|
```
|
|
|
|
|
|
The above prompt will be skipped if the value of the previous prompt is less than 3.
|
|
|
|
|
|
### type
|
|
|
|
|
|
Type: `String|Function`
|
|
|
|
|
|
Defines the type of prompt to display. See the list of [prompt types](#-types) for valid values.
|
|
|
|
|
|
If `type` is a falsy value the prompter will skip that question.
|
|
|
```js
|
|
|
{
|
|
|
type: null,
|
|
|
name: 'forgetme',
|
|
|
message: `I'll never be shown anyway`,
|
|
|
}
|
|
|
```
|
|
|
|
|
|
### name
|
|
|
|
|
|
Type: `String|Function`
|
|
|
|
|
|
The response will be saved under this key/property in the returned response object.
|
|
|
In case you have multiple prompts with the same name only the latest response will be stored.
|
|
|
|
|
|
> Make sure to give prompts unique names if you don't want to overwrite previous values.
|
|
|
|
|
|
### message
|
|
|
|
|
|
Type: `String|Function`
|
|
|
|
|
|
The message to be displayed to the user.
|
|
|
|
|
|
### initial
|
|
|
|
|
|
Type: `String|Function`
|
|
|
|
|
|
Optional default prompt value. Async functions are supported too.
|
|
|
|
|
|
### format
|
|
|
|
|
|
Type: `Function`
|
|
|
|
|
|
Receive the user input and return the formatted value to be used inside the program.
|
|
|
The value returned will be added to the response object.
|
|
|
|
|
|
The function signature is `(val, values)`, where `val` is the value from the current prompt and
|
|
|
`values` is the current response object in case you need to format based on previous responses.
|
|
|
|
|
|
**Example:**
|
|
|
```js
|
|
|
{
|
|
|
type: 'number',
|
|
|
name: 'price',
|
|
|
message: 'Enter price',
|
|
|
format: val => Intl.NumberFormat(undefined, { style: 'currency', currency: 'USD' }).format(val);
|
|
|
}
|
|
|
```
|
|
|
|
|
|
### onRender
|
|
|
|
|
|
Type: `Function`
|
|
|
|
|
|
Callback for when the prompt is rendered.
|
|
|
The function receives [kleur](https://github.com/lukeed/kleur) as its first argument and `this` refers to the current prompt.
|
|
|
|
|
|
**Example:**
|
|
|
```js
|
|
|
{
|
|
|
type: 'number',
|
|
|
message: 'This message will be overridden',
|
|
|
onRender(kleur) {
|
|
|
this.msg = kleur.cyan('Enter a number');
|
|
|
}
|
|
|
}
|
|
|
```
|
|
|
|
|
|
### onState
|
|
|
|
|
|
Type: `Function`
|
|
|
|
|
|
Callback for when the state of the current prompt changes.
|
|
|
The function signature is `(state)` where `state` is an object with a snapshot of the current state.
|
|
|
The state object has two properties `value` and `aborted`. E.g `{ value: 'This is ', aborted: false }`
|
|
|
|
|
|
### stdin and stdout
|
|
|
|
|
|
Type: `Stream`
|
|
|
|
|
|
By default, prompts uses `process.stdin` for receiving input and `process.stdout` for writing output.
|
|
|
If you need to use different streams, for instance `process.stderr`, you can set these with the `stdin` and `stdout` properties.
