Add TypeScript export functionality for DTO classes

[Copilot]

This PR implements TypeScript export functionality that generates TypeScript interface definitions from DTO classes, bringing feature parity with the Laravel Validated DTO package as requested in the issue.

Features Added

New Export Command

A new export:typescript command that scans DTO classes and generates TypeScript interfaces:

# Basic usage
php bin/hyperf.php export:typescript
# With custom options
php bin/hyperf.php export:typescript /custom/dto/path --output=/output/dir --filename=interfaces.ts

Intelligent Type Mapping

Comprehensive mapping from PHP cast types to TypeScript types:

• StringCast → string
• IntegerCast, FloatCast → number
• BooleanCast → boolean
• EnumCast → Union types (e.g., 'active' | 'inactive')
• DTOCast → Interface references
• ArrayCast → any[]
• ModelCast → object
• And more...

Example Output

Given a DTO like this:

class UserDTO extends ValidatedDTO
{
protectedfunctionrules(): array
{
return [
'name' => ['required', 'string'],
'email' => ['required', 'email'],
'age' => ['integer'],
'is_active' => ['boolean'],
];
}
protectedfunctioncasts(): array
{
return [
'name' => newStringCast(),
'email' => newStringCast(),
'age' => newIntegerCast(),
'is_active' => newBooleanCast(),
];
}
protectedfunctiondefaults(): array
{
return ['is_active' => true];
}
}

The export generates:

exportinterfaceUserInterface{name: string;email: string;age: number;is_active?: boolean;// Optional because it has a default value}

Technical Implementation

• ExportTypescriptCommand: Console command with flexible path and output options
• TypescriptExporter: Core logic for scanning DTO classes and generating interfaces
• Enhanced enum support: Automatically generates TypeScript union types from PHP enum cases
• Smart optionality: Properties marked optional based on default values and validation rules
• Configuration integration: Works with existing DTO configuration system

Configuration

Added TypeScript export configuration to the DTO config file:

'typescript' => [
'output_path' => BASE_PATH . '/resources/typescript',
'filename' => 'dtos.ts',
],

This implementation provides type safety for frontend applications while maintaining compatibility with the existing Hyperf ecosystem conventions.

Fixes#2.

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
