TypeSharp CLI 🔷

Automatically generate TypeScript from C# — keep your frontend and backend types in perfect sync.

TypeSharp is a developer-first CLI tool built for teams working with ASP.NET Core backends and TypeScript frontends (Vue, Nuxt, React, Angular). Stop duplicating your models. Let TypeSharp do it.

    public int Id { get; set; }
    public string Name { get; set; }
    public decimal? Price { get; set; }
    public ProductCategory Category { get; set; }
