Ionic2: How to include signalr?

Question

Trying to utilize signalr in Ionic2.

Steps taken:

• Installed signalr@2.2.1 and jquery@2.2.3 with npm.
• Importing them with

   import * as $ from 'node_modules/jquery';
   import 'node_modules/signalr';
  

• Trying to establish connection with server with $.hubConnection(..)
• Fails on run, giving following error:

jQuery was not found. Please ensure jQuery is referenced before the SignalR client JavaScript file.

Answer 1

I've found two options that have worked for me so far.

Option 1: You can add this block of code to the top of the jquery.signalR.js script file var $ = require('jquery'); window.jQuery = $;

Option 2: You can download signar-no-jquery package. This package worked out of the box for me.

Goodluck
