Azure Function examples in Java

To run it on your machine just use the following commands:

cd {folder}
mvn clean install
mvn azure-functions:run

Deploy to Azure Functions with mvn azure-functions:deploy:

mvn azure-functions:deploy

Run the following command to view near real-time streaming logs:

func azure functionapp logstream <APP_NAME> 

You need to have an Azure Subscription to deploy to Azure. Checkout Azure's free offerings And you need to be logged-in to your Azure Account within your az-cli. Run az login to log in.

Make sure to follow the best practices for Azure Functions:

• Avoid long running functions
• Take care of cross function communication
• Make your functions stateless
• Write defensive functions
• Organize functions for performance and scaling
• Don't mix test and production code in the same function app
