# SignalR
The **SignalR** service incorporates the required functionality to allow for:
* SignalR and/or REST requests to your service
* JWT Authentication of those requests
* The handling of the operations that are to be executed when a request is received
{% hint style="info" %}
**Quick Steps**
1. Add `SignalR` **plugin** to your solution.
2. Drag the `SignalR` service onto the Solution Explorer panel.
3. Set **properties** for the service. (See below for details.)
4. Add Server method (e.g. SendMessage) and Client method (e.g. ReceiveMessage) in the Methods Editor.
5. Drag required **functions** and **types** onto the design canvas of an event that was created for your service when you added the Server method (e.g. SendMessage) in the previous step.
6. Click **Debug** (on the top toolbar) to test and debug your solution, or right-click on the service or service event (in the Solution Explorer), then select Debug to specifically test and debug the service.

## Properties
### Hub URL
SignalR hub URL, e.g. `http://localhost/chatHub`.
**What is a hub?**\
SignalR uses hubs to communicate between clients and servers. [learn more](https://docs.microsoft.com/en-us/aspnet/core/signalr/introduction?view=aspnetcore-5.0).

### Security
The type of security used for authentication.
Select either `None` or `JWT Authentication`.
When selecting JWT Authentication, provide the following:
#### Secret key
Secret key used to validate the JWT token.
#### Claims
Comma-separated list of claim names to resolve on the event input, e.g. `"name,exp"`.

### Server methods
Click the **...** icon to open the `Methods Editor` to add a collection of server-side SignalR methods.
Specify the names and parameters of the server methods that are to be executed as events when your SignalR service is accessed.
### Client methods
Click the **...** icon to open the `Methods Editor` to add a collection of client-side SignalR methods.
Specify the names and parameters of the client methods that are to be executed as events when your SignalR service is accessed.

**Note:**\
For each `Event` that is created, you have to add relevant functions to that Event to execute the associated Method.
