Introducing SignalR.TypeScript

Hello, fellow programmers.

If you, like me, love both SignalR and TypeScript, you might find this interesting and/or useful.

What is this?

SignalR.TypeScript helps you generate TypeScript type definitions for your SignalR hubs. It also generates type definitions for the items you pass between client and server.

Some benefits of using TypeScript include:

If you prefer to use TypeScript instead of raw JavaScript on your client code, this tool can be really handy and would save you from hand-rolling your .d.ts files or using “any” everywhere. Please note that this is still in “alpha” so there might be rough edges.

How do I use this with Visual Studio 2012 or 2013?

Supported .NET types

Known issues/current limitations
