⚡ API Starter Kit

Declare your data model once. Generate everything.

---

A CLI tool that scaffolds full‑stack API projects from a declarative schema file.
Write your data model in .storm format and get complete, production‑ready backend code — controllers, services, models, DTOs, migrations, OpenAPI annotations — in C# (.NET) or PHP (Laravel 12+) with zero boilerplate.

---

📦 Quick Start

# 1. Install Python dependencies
pip install -r requirements.txt

# 2. Scaffold a project (pick your template)
python main.py --init --template dotnet-csharp --name MyApi          # .NET
python main.py --init --template laravel-php                         # Laravel

# 3. Edit schema.storm to define your data model

# 4. Generate all source files
python main.py --generate

📐 Schema Language (.storm)

Define your entire data model in a clean, readable syntax — one file, no ceremony.

// ═══ Enums ═══════════════════════════════════════════════════════════════

enum Status {
    Active   = "active",
    Inactive = "inactive",
    Pending  = "pending"
}

enum Role {
    Admin = "admin",
    User  = "user"
}

// ═══ Tables ═════════════════════════════════════════════════════════════

table User {
    id:        uuid pk;
    name:      string(min=2, max=100);
    email:     string(max=255) unique;
    password:  string(max=255);
    role:      Role;
    status:    Status;
    createdAt: datetime;
    updatedAt: datetime;
}

table Product {
    id:        int? pk;
    name:      string(min=1, max=200);
    price:     double(min=0) = 0;
    stock:     int(min=0) = 0;
    status:    Status;
    ownerId:   uuid;
    owner:     User;            // ← FK: BelongsTo User
    createdAt: datetime;
    updatedAt: datetime;
}

🔤 Type System

Storm Type	C#	PHP / OA	Migration	Notes
int	int	integer	integer	Supports pk, unique, min, max
long	long	integer	bigInteger
float	float	number	float
double	double	number	double
string	string	string	string	Supports min, max
bool	bool	boolean	boolean
uuid	Guid	string	uuid
datetime	DateTime	string (date‑time)	dateTime

• Append ? for nullable: int?, uuid?
• Reference another table → foreign key (BelongsTo / HasMany generated automatically)
• Reference an enum → typed enum column with casts
• Default values support constant expressions: price:double = 0, qty:int = 5 * 4

🧮 Expressions

Constant expressions in default values are evaluated at parse time:

Expression	Result
5 * 4	20
(1 + 2) * 3	9
-5	-5
!true	false
