A flexible CSharp to TypeScript generator that is Gulp, Webpack and Grunt friendly, written in TypeScript.

Uses the following library for parsing C# code from TypeScript: https://github.com/ffMathy/FluffySpoon.JavaScript.CSharpParser

Usage examples

These recipes help you quickly get started with common scenarios you may need. Feel free to contribute with your own!

The following code shows general usage. The examples below only differ in the EmitOptions provided.

import { Emitter } from '@fluffy-spoon/csharp-to-typescript-generator';

var csharpCode = "insert the CSharp model code here - you could also read it from a file.";
var emitter = new Emitter(csharpCode);
var options = <EmitOptions>{ 
  defaults: <DefaultEmitOptions>{ },
  file: <FileEmitOptions>{ }
var typescriptCode = emitter.emitFile(options);

Default settings

var typescriptCode = emitter.emit();

Given the following CSharp model code:

namespace MyNamespace {
  public class MyClass {
    public bool myField;
    public int MyProperty { get; set; }
    public string MyOtherProperty { get; set; }
    public double? MyNullableProperty { get; set; }
    public class MySubclass {
      public List<string> MyListProperty { get; set; }
      public MyGenericType<SomeType, SomeOtherType> MyGenericProperty { get; set; }
      public Task MyFunction(string input1, int input2) { 
        //some code

The following TypeScript code would be generated:

declare namespace MyNamespace {
  interface MyClass {
    myField: boolean;
    myProperty: number;
    myOtherProperty: string;
    myNullableProperty?: number;
  namespace MyClass {
    interface MySubclass {
      myListProperty: string[];
      myGenericProperty: MyGenericType<SomeType, SomeOtherType>;
      MyFunction(input1: string, input2: number): Promise;
