Laravel Prompts Skill

Laravel Prompts is a PHP package for adding beautiful and user-friendly forms to your command-line applications, with browser-like features including placeholder text and validation. It's pre-installed in Laravel and supports macOS, Linux, and Windows with WSL.

When to Use This Skill

This skill should be triggered when:

• Building Laravel Artisan commands with interactive prompts
• Creating user-friendly CLI applications in PHP
• Implementing form validation in command-line tools
• Adding text input, select menus, or confirmation dialogs to console commands
• Working with progress bars, loading spinners, or tables in CLI applications
• Testing Laravel console commands with prompts
• Converting simple console input to modern, validated, interactive prompts

Quick Reference

Basic Text Input

use function Laravel\Prompts\text;

// Simple text input
$name = text('What is your name?');

// With placeholder and validation
$name = text(
    label: 'What is your name?',
    placeholder: 'E.g. Taylor Otwell',
    required: true,
    validate: fn (string $value) => match (true) {
        strlen($value) < 3 => 'The name must be at least 3 characters.',
        strlen($value) > 255 => 'The name must not exceed 255 characters.',
        default => null
    }
);

Password Input

use function Laravel\Prompts\password;

$password = password(
    label: 'What is your password?',
    placeholder: 'password',
    hint: 'Minimum 8 characters.',
    required: true,
    validate: fn (string $value) => match (true) {
        strlen($value) < 8 => 'The password must be at least 8 characters.',
        default => null
    }
);

Select (Single Choice)

use function Laravel\Prompts\select;

// Simple select
$role = select(
    label: 'What role should the user have?',
    options: ['Member', 'Contributor', 'Owner']
);

// With associative array (returns key)
$role = select(
    label: 'What role should the user have?',
    options: [
        'member' => 'Member',
        'contributor' => 'Contributor',
        'owner' => 'Owner',
    ],
    default: 'owner'
);

// From database with custom scroll
$role = select(
    label: 'Which category would you like to assign?',
    options: Category::pluck('name', 'id'),
    scroll: 10
);

Multiselect (Multiple Choices)

use function Laravel\Prompts\multiselect;

$permissions = multiselect(
    label: 'What permissions should be assigned?',
    options: ['Read', 'Create', 'Update', 'Delete'],
    default: ['Read', 'Create'],
    hint: 'Permissions may be updated at any time.'
);

// With validation
$permissions = multiselect(
    label: 'What permissions should the user have?',
    options: [
        'read' => 'Read',
        'create' => 'Create',
        'update' => 'Update',
        'delete' => 'Delete',
    ],
    validate: fn (array $values) => ! in_array('read', $values)
        ? 'All users require the read permission.'
        : null
);

Confirmation Dialog

use function Laravel\Prompts\confirm;

// Simple yes/no
$confirmed = confirm('Do you accept the terms?');

// With custom labels
$confirmed = confirm(
    label: 'Do you accept the terms?',
    default: false,
    yes: 'I accept',
    no: 'I decline',
    hint: 'The terms must be accepted to continue.'
);

// Require "Yes"
$confirmed = confirm(
    label: 'Do you accept the terms?',
    required: true
);

Search (Searchable Select)

use function Laravel\Prompts\search;

$id = search(
    label: 'Search for the user that should receive the mail',
    placeholder: 'E.g. Taylor Otwell',
    options: fn (string $value) => strlen($value) > 0
        ? User::whereLike('name', "%{$value}%")->pluck('name', 'id')->all()
        : [],
    hint: 'The user will receive an email immediately.',
    scroll: 10
);

Suggest (Auto-completion)

use function Laravel\Prompts\suggest;

// Static options
$name = suggest('What is your name?', ['Taylor', 'Dayle']);

// Dynamic filtering
$name = suggest(
    label: 'What is your name?',
    options: fn ($value) => collect(['Taylor', 'Dayle'])
        ->filter(fn ($name) => Str::contains($name, $value, ignoreCase: true))
);

Multi-step Forms

use function Laravel\Prompts\form;

$responses = form()
    ->text('What is your name?', required: true, name: 'name')
    ->password(
        label: 'What is your password?',
        validate: ['password' => 'min:8'],
        name: 'password'
    )
    ->confirm('Do you accept the terms?')
    ->submit();

// Access named responses
echo $responses['name'];
echo $responses['password'];

// Dynamic forms with previous responses
$responses = form()
    ->text('What is your name?', required: true, name: 'name')
    ->add(function ($responses) {
        return text("How old are you, {$responses['name']}?");
    }, name: 'age')
    ->submit();

Progress Bar

use function Laravel\Prompts\progress;

// Simple usage
$users = progress(
    label: 'Updating users',
    steps: User::all(),
    callback: fn ($user) => $this->performTask($user)
);

// With dynamic labels
$users = progress(
    label: 'Updating users',
    steps: User::all(),
    callback: function ($user, $progress) {
        $progress
            ->label("Updating {$user->name}")
            ->hint("Created on {$user->created_at}");
        return $this->performTask($user);
    },
    hint: 'This may take some time.'
);

Loading Spinner

use function Laravel\Prompts\spin;

$response = spin(
    callback: fn () => Http::get('http://example.com'),
    message: 'Fetching response...'
);

Key Concepts

Input Types

Laravel Prompts provides several input types for different use cases:

• text() - Single-line text input with optional placeholder and validation
• textarea() - Multi-line text input for longer content
• password() - Masked text input for sensitive data
• confirm() - Yes/No confirmation dialog
• select() - Single selection from a list of options
• multiselect() - Multiple selections from a list
• suggest() - Text input with auto-completion suggestions
• search() - Searchable single selection with dynamic options
• multisearch() - Searchable multiple selections
• pause() - Pause execution until user presses ENTER

Output Types

For displaying information without input:

• info() - Display informational message
• note() - Display a note
• warning() - Display warning message
• error() - Display error message
• alert() - Display alert message
• table() - Display tabular data

Validation

Three ways to validate prompts:

1. Closure validation: Custom logic with match expressions validate: fn (string $value) => match (true) {strlen($value) < 3 => 'Too short.', default => null}
2. Laravel validation rules: Standard Laravel validation validate: ['email' => 'required|email|unique:users']
3. Required flag: Simple requirement check required: true

Transformation

Use the transform parameter to modify input before validation:

$name = text(
    label: 'What is your name?',
    transform: fn (string $value) => trim($value),
    validate: fn (string $value) => strlen($value) < 3
        ? 'The name must be at least 3 characters.'
        : null
);

Terminal Features

• Scrolling: Configure visible items with scroll parameter (default: 5)
• Navigation: Use arrow keys, j/k keys, or vim-style navigation
• Forms: Press CTRL + U in forms to return to previous prompts
• Width: Keep labels under 74 characters for 80-character terminals

Working with This Skill

For Beginners

Start with basic prompts:

1. Use text() for simple input
2. Add required: true for mandatory fields
3. Try confirm() for yes/no questions
4. Use select() for predefined choices

Example beginner command:

$name = text('What is your name?', required: true);
$confirmed = confirm('Is this correct?');
if ($confirmed) {
    $this->info("Hello, {$name}!");
}

For Intermediate Users

Combine multiple prompts and add validation:

1. Use the form() API for multi-step input
2. Add custom validation with closures
3. Use search() for database queries
4. Implement progress bars for long operations

Example intermediate command:

$responses = form()
    ->text('Name', required: true, name: 'name')
    ->select('Role', options: ['Member', 'Admin'], name: 'role')
    ->confirm('Create user?')
    ->submit();

if ($responses) {
    progress(
        label: 'Creating user',
        steps: 5,
        callback: fn () => sleep(1)
    );
}

For Advanced Users

Leverage advanced features:

1. Dynamic form fields based on previous responses
2. Complex validation with Laravel validation rules
3. Custom searchable prompts with database integration
4. Transformation functions for data normalization
5. Testing strategies for command prompts

Example advanced command:

$responses = form()
    ->text('Email', validate: ['email' => 'required|email|unique:users'], name: 'email')
    ->add(function ($responses) {
        return search(
            label: 'Select manager',
            options: fn ($value) => User::where('email', 'like', "%{$value}%")
                ->where('email', '!=', $responses['email'])
                ->pluck('name', 'id')
                ->all()
        );
    }, name: 'manager_id')
    ->multiselect(
        label: 'Permissions',
        options: Permission::pluck('name', 'id'),
        validate: fn ($values) => count($values) === 0 ? 'Select at least one permission.' : null,
        name: 'permissions'
    )
    ->submit();

Navigation Tips

• Arrow keys or j/k - Navigate options in select/multiselect
• Space - Select/deselect in multiselect
• Enter - Confirm selection or submit input
• CTRL + U - Go back to previous prompt (in forms)
• Type to search - In search/multisearch prompts
• Tab - Auto-complete in suggest prompts

Testing

Test commands with prompts using Laravel's built-in assertions:

use function Pest\Laravel\artisan;

test('user creation command', function () {
    artisan('users:create')
        ->expectsQuestion('What is your name?', 'Taylor Otwell')
        ->expectsQuestion('What is your email?', '[email protected]')
        ->expectsConfirmation('Create this user?', 'yes')
        ->expectsPromptsInfo('User created successfully!')
        ->assertExitCode(0);
});

test('displays warnings and errors', function () {
    artisan('report:generate')
        ->expectsPromptsWarning('This action cannot be undone')
        ->expectsPromptsError('Something went wrong')
        ->expectsPromptsTable(
            headers: ['Name', 'Email'],
            rows: [
                ['Taylor Otwell', '[email protected]'],
                ['Jason Beggs', '[email protected]'],
            ]
        )
        ->assertExitCode(0);
});

Best Practices

Design Guidelines

• Keep labels concise (under 74 characters for 80-column terminals)
• Use hint parameter for additional context
• Set appropriate default values when sensible
• Configure scroll for lists with many options (default: 5)

Validation Strategy

• Use required: true for mandatory fields
• Apply Laravel validation rules for standard checks (email, min/max, etc.)
• Use closures for complex business logic validation
• Provide clear, actionable error messages

User Experience

• Add placeholders to show expected input format
• Use pause() before destructive operations
• Show progress bars for operations taking >2 seconds
• Display informational messages after actions complete
• Group related prompts in forms for better flow

Performance

• Use search() callbacks with length checks to avoid expensive queries: options: fn (string $value) => strlen($value) > 0? User::where('name', 'like', "%{$value}%")->pluck('name', 'id')->all(): []
• Limit database results with pagination or top-N queries
• Cache frequently-accessed option lists
• Use spin() for HTTP requests and long operations

Common Patterns

User Registration Flow

$responses = form()
    ->text('Name', required: true, name: 'name')
    ->text('Email', validate: ['email' => 'required|email|unique:users'], name: 'email')
    ->password('Password', validate: ['password' => 'required|min:8'], name: 'password')
    ->submit();

Confirmation Before Destructive Action

$confirmed = confirm(
    label: 'Are you sure you want to delete all users?',
    default: false,
    hint: 'This action cannot be undone.'
);

if (! $confirmed) {
    $this->info('Operation cancelled.');
    return;
}

Dynamic Multi-step Form

$responses = form()
    ->select('User type', options: ['Regular', 'Admin'], name: 'type')
    ->add(function ($responses) {
        if ($responses['type'] === 'Admin') {
            return password('Admin password', required: true);
        }
    }, name: 'admin_password')
    ->submit();

Batch Processing with Progress

$items = Item::all();

$results = progress(
    label: 'Processing items',
    steps: $items,
    callback: function ($item, $progress) {
        $progress->hint("Processing: {$item->name}");
        return $this->process($item);
    }
);
