SignalR Share

This is a very simple .NET Core app with two signalR endpoints:

• Join Must be called with a string as group identifier. You'll subscribe to subsequent messages in the same group.
• Share Must be called with a string as group identifier, and any object as state data. That state data will be passed to Update() called on all other clients in the identified group.

Build and run

1. Open folder in VSCode
2. Ensure VSCode's C# extension is installed
3. Press F5 to build and run

Running on a server

You can adapt this to your CORS needs, I instead run both my SignalR client and this service on the same Apache virtual host. I proxy traffic on the /share endpoint to this service. These are the relevant lines of my configuration file.

RewriteEngine On
<Location /share>
  RewriteRule .* "ws://localhost:5000/share" [P,L]
</Location>
# If an existing asset or directory is requested go to it as it is
RewriteCond %{DOCUMENT_ROOT}%{REQUEST_URI} -f [OR]
RewriteCond %{DOCUMENT_ROOT}%{REQUEST_URI} -d
RewriteRule ^ - [L]

# If the requested resource doesn't exist, use index.html (SignalR client web-app)
RewriteRule ^ /index.html

This probably requires:

sudo a2enmod proxy_wstunnel rewrite
