JavaScript and TypeScript clients for SignalR for ASP.NET Core

npm install @aspnet/signalr

See the SignalR Documentation at docs.microsoft.com for documentation on the latest release.

To use the client in a browser, copy *.js files from the dist/browser folder to your script folder include on your page using the <script> tag.

The following polyfills are required to use the client in Node.js applications:

• XmlHttpRequest - always
• WebSockets - to use the WebSockets transport
• EventSource - to use the ServerSentEvents transport
• btoa/atob - to use binary protocols (e.g. MessagePack) over text transports (ServerSentEvents)

    console.log(data);
});

    .then(() => connection.invoke("send", "Hello"));
