@aspnet/signalr

JavaScript and TypeScript clients for SignalR for ASP.NET Core

Installation

npm install @aspnet/signalr

Usage

Browser

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.

Node.js

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)

Example (Browser)

let connection = new signalR.HubConnection('/chat');

connection.on('send', data => {
    console.log(data);
});

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

Example (NodeJS)

const signalR = require("@aspnet/signalr");

let connection = new signalR.HubConnection('/chat');

connection.on('send', data => {
    console.log(data);
});

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