SignalR Service bindings for Azure Functions
This set of articles explains how to authenticate and send real-time messages to clients connected to Azure SignalR Service by using SignalR Service bindings in Azure Functions. Azure Functions supports input and output bindings for SignalR Service.
|Return the service endpoint URL and access token||Input binding|
|Send SignalR Service messages||Output binding|
Add to your Functions app
Functions 2.x and higher
Working with the trigger and bindings requires that you reference the appropriate package. The NuGet package is used for .NET class libraries while the extension bundle is used for all other application types.
|C#||Installing the NuGet package, version 3.x|
|C# Script (online-only in Azure portal)||Adding a binding||To update existing binding extensions without having to republish your function app, see Update your extensions.|
For details on how to configure and use SignalR Service and Azure Functions together, refer to Azure Functions development and configuration with Azure SignalR Service.
Annotations library (Java only)
To use the SignalR Service annotations in Java functions, you need to add a dependency to the azure-functions-java-library-signalr artifact (version 1.0 or higher) to your pom.xml file.
<dependency> <groupId>com.microsoft.azure.functions</groupId> <artifactId>azure-functions-java-library-signalr</artifactId> <version>1.0.0</version> </dependency>
