ts-class-gen

A simple and powerful TypeScript class generator library that helps you programmatically generate TypeScript classes, interfaces, methods, and properties with clean, readable code.

Features

• 🚀 Simple API - Easy-to-use fluent interface for code generation
• 📝 TypeScript Support - Full TypeScript support with type definitions
• 🎯 Flexible - Generate classes, interfaces, methods, properties, and complete files
• 🔧 Customizable - Support for access modifiers, static members, inheritance, and more
• 📦 Lightweight - Minimal dependencies, focused on core functionality

Installation

npm install ts-class-gen

Quick Start

import { CGClass, CGProperty, CGMethod, CGFile, CGAccess } from 'ts-class-gen';

// Create a property
const idProperty = new CGProperty();
idProperty.name = 'id';
idProperty.type = 'number';
idProperty.access = CGAccess.private;

// Create a method
const getIdMethod = new CGMethod();
getIdMethod.name = 'getId';
getIdMethod.returnType = 'number';
getIdMethod.access = CGAccess.public;
getIdMethod.addBodyCode('return this.id;');

// Create a class
const userClass = new CGClass();
userClass.name = 'User';
userClass.isExport = true;
userClass.addProperty(idProperty);
userClass.addMethod(getIdMethod);

// Create a file
const file = new CGFile();
file.addClass(userClass);

// Generate the code
console.log(file.toString());

This will generate:

export class User {
    // #region Properties
    private id: number;
    // #endregion

    // #region Methods
    public getId(): number {
        return this.id;
    }
    // #endregion
}

API Reference

Core Classes

• CGClass - Generate TypeScript classes with properties, methods, inheritance
• CGInterface - Generate TypeScript interfaces
• CGProperty - Generate class/interface properties with types and access modifiers
• CGMethod - Generate methods with parameters and body code
• CGParameter - Generate method parameters
• CGFile - Generate complete TypeScript files with imports and multiple classes/interfaces

Enums

• CGAccess - Access modifiers: public, private, protected

Utilities

• StringBuilder - Efficient string building
• CGHelper - Helper methods for code generation

Advanced Usage

// Complex class with inheritance
const userClass = new CGClass();
userClass.name = 'User';
userClass.extendsClass = 'Person';
userClass.implementsInterfaces = ['IUser'];

// Complete file generation
const file = new CGFile();
file.addImport('import { BaseEntity } from "./base";');
file.addClass(userClass);
const code = file.toString();
