SignalR connection with typescript in .NET MVC project

To connect to SignalR in a .NET MVC project using TypeScript, you need to perform the following steps:


Install the SignalR client library for TypeScript: npm install @aspnet/signalr

Import the library in your TypeScript file: import * as signalR from "@aspnet/signalr";

Create a connection to the SignalR hub:

javascript

Copy code

const connection = new signalR.HubConnectionBuilder()

    .withUrl("/chatHub")

    .build();

Start the connection: await connection.start();

Register for hub events:

typescript

Copy code

connection.on("ReceiveMessage", (user: string, message: string) => {

    console.log(user + ": " + message);

});

Call methods on the hub: connection.invoke("SendMessage", user, message);

These are the basic steps to connect to SignalR in a .NET MVC project using TypeScript. For more detailed information, you can refer to the official SignalR documentation: https://docs.microsoft.com/en-us/aspnet/core/signalr/javascript-client?view=aspnetcore-3.1


You can also handle connection errors and disconnections:

javascript

Copy code

connection.onclose(() => {

    console.error("Disconnected");

});


connection.start().catch(err => {

    console.error(err.toString());

});

Finally, to stop the connection, you can use the connection.stop() method.

These are the basic steps to connect to SignalR in a .NET MVC project using TypeScript. It's important to note that the above code is just a sample and may need to be modified to fit your specific use case.
