Laravel Typegen is an awesome library that lets you generate TypeScript types from your Laravel code

Features

• Generate TypeScript types from Laravel models
• Support Relationhips
• Support Enum (from PHP8.1)
• Generate route.d.ts file for ziggy
• Provide useful types for Laravel (e.g. pagination, etc.)

Installation

You can install this package via composer:

$ npm install -D @7nohe/laravel-typegen

Usage

Edit package.json

{
    "scripts": {
        "typegen": "laravel-typegen"
    },
}

$ npm run typegen

Enum Support

We also support php8.1 enums.

<!-- app/Enums/GenderType.php -->
<?php

namespace App\Enums;

enum GenderType: string
{
    case Male = 'Male';
    case Female = 'Female';
    case Other = 'Other';
}

Then,cast model attributes to enums.

<!-- app/Models/User.php -->
<?php

namespace App\Models;
use App\Enums\GenderType;

class User extends Authenticatable
{
    /**
     * The attributes that should be cast.
     *
     * @var array<string, string>
     */
    protected $casts = [
        'gender'            => GenderType::class,
    ];

This library will generate the following TypeScript types:

export type User = {
    id: number;
    name: string;
    email: string;
    gender: GenderType;
    email_verified_at?: string;
    created_at?: string;
    updated_at?: string;
    posts?: Post[];
};
export enum GenderType {
    Male = "Male",
    Female = "Female",
    Other = "Other"
}

Laravel Enum Support

If you use Laravel Enum, use the option --laravel-enum.

{
    "scripts": {
        "typegen": "laravel-typegen --laravel-enum"
    },
}
