In this tutorial, you will learn about using WebSharper UI to implement a simple Model-View-Update (MVU) application pattern, similar to the Elm architecture. In subsequent tutorials, you will learn about enhancing this pattern to a full-scale application development architecture (The WebSharper Architecture) that has superior performance and sufficient flexibility to implement any type of web application.

On a single-pane of glass, users can get cost visibility, monitor & secure resources, and perform operations - all in real-time. In the last post, we look at how you can implement pub-sub with AWS Lambda. We compared several event sources you can use, SNS, Kinesis streams and DynamoDB streams, and the tradeoffs available to you. Let’s look at another messag[...]
