Node API for .NET

Advanced interoperability between .NET and JavaScript in the same process

Call .NET from JS

Load .NET assemblies from JavaScript and use nearly any APIs.

Run Node.js or another JS runtime in a .NET application, with advanced interop capabilities.

Automatically generate TypeScript type definitions for .NET assemblies.

Optionally compile a C# library to a fully native Node.js addon that does not depend on the .NET runtime.

Pass classes, collections, streams, and more seamlessly between JS and .NET.

Build-time source-generation or runtime code-generation optimizes interop performance.

.NET exceptions convert to/from JS errors, with combined stack traces.
