Q: Initiate a message from server to client(s) #200

Open KingKnecht opened 3 years ago

KingKnecht commented 3 years ago

I'm trying to figure out how I could send messages from the server to clients. I have searched the issues here and found some topics about SignalR, but I have no idea how to do that nor if it is possible at all at the moment.

My example is the book list from the template. I can remove a book by its ISBN and I want other clients to have the modified list of books in sync.

There is BookService with following function:

removeBookByIsbn = ctx.Authorize <| fun isbn -> async {
    books.RemoveAll(fun b -> b.isbn = isbn) |> ignore
    //How to inform clients that the list has changed?
}

Thx

Hi @KingKnecht,

take a look at this sample - it shows how to properly setup a SignalR Hub for broadcasting.

Is there a Bolero project template that uses SignalR for real-time communication (not just one-way broadcast) between server and client rather than XHR requests?
