connect(url) issues

[zhangboli51]

SO this is the error referring from : this.connected = await this.hubService.connect(url).toPromise();

and URL refer to const url = 'http://localhost:4200/signalr';

and the following is error from compiler.

ERROR in C:/Users/bgm3325/Desktop/easystart/irm-pro/src/app/app.component.ts (63,52): Argument of type '"http://localhost:4200/signalr"' is not assignable to parameter of type 'boolean'.

Whoops, looks like last version I accidentally removed that.

I will update in a few minutes and let you know when to install latest.

[stephen-moyer]

Fixed. Install latest npm install ngx-signalr-hubservice@latest --save and you should be good to go. LMK if it works.

You have to include jQuery in your index.html for signalr to work.

[zhangboli51]

Just simply add this <script src="https://ajax.aspnetcdn.com/ajax/jQuery/jquery-3.2.1.min.js"></script> to my index.html , but it doesn't work.

testsignalr.zip Try this test project I use. It should work.

[stephen-moyer]

Are you sure you have an asp.net signalr server running? You need to change the port the app is trying to connect to.

[stephen-moyer]

You need to change the url you're using for your signalr server.
