Use this book to learn the Distributed Application Runtime (Dapr), a new event-driven runtime from Microsoft designed to help developers build microservices applications, using a palette of languages and frameworks that run everywhere: on-premises, in any cloud, and even on the edge. One of the most popular architectural patterns for implementing large, complex, distributed solutions is the microservices architectural style. Because solutions are composed of services based on various languages, frameworks, and platforms, the more complex and compartmentalized an application becomes, the more considerations a developer has to keep in mind. Much of the time this proves to be difficult. Introducing Distributed Application Runtime (Dapr) is your guide to achieving more with less through patterns. Part I of the book is about understanding microservices and getting up and running with Dapr, either on your machine or in any Kubernetes cluster. From there you are guided through the concepts of Dapr, how it works, and what it can do for you. You will wrap up with various ways to debug Dapr applications using Visual Studio Code locally, inside a container or Kubernetes. In Part II you will jump into the reusable patterns and practices, the building blocks of Dapr. You will go from service invocation, publish and subscribe, state management, resource bindings, and the Actor model to secrets; each building block is covered in detail in its own dedicated chapter. You will learn what Dapr offers from a functional perspective and also how you can leverage the three pillars of observability (logs, metrics, and traces) in order to gain insight into your applications. In Part III you will explore advanced concepts, including using middleware pipelines, integrating Dapr into web frameworks such as ASP.NET Core, or the runtimes of Azure Logic Apps and Azure Functions. The book features a multi-versed set of examples that cover not only the plain API of Dapr, but also the .NET SDK. Hence, most of the examples are in .NET 5, with a small number in JavaScript to exemplify the use of multiple languages. Examples show you how to securely use Dapr to leverage a variety of services in Microsoft Azure, including Azure Kubernetes Service, Azure Storage, Azure Service Bus, Azure Event Grid, Azure Key Vault, Azure Monitor, and Azure Active Directory among others. What You Will Learn Recognize the challenges and boundaries of microservices architecture Host Dapr inside a Kubernetes cluster or as a standalone process Leverage and use Dapr's ready-to-use patterns and practices Utilize its HTTP/gRPC APIs Use Dapr with ASP.NET Core and in .NET applications (with or without the SDK) Implement observability for Dapr applications Secure Dapr applications Integrate Dapr with the runtime of Azure Logic Apps and Azure Functions Realize the full potential of Visual Studio Code by using the right extensions that will contribute to a better development experience Who This Book Is For Developers and architects who want to utilize a proven set of patterns to help easily implement microservices applications

Learn how to build front-end applications that can help you ship applications faster with fewer defects. Many software projects fail because they are not planned well, or lack organization. Applying strategies from other industries can help you create better software. This book explores the "mise en place" technique from cooking and reveals how you can apply it to the art of creating software. In many professional kitchens, the work of preparing a meal is divided and performed in workstations to help create the whole. You'll review the philosophy behind this and see how to leverage this approach in your code. You'll also learn to visualize your applications as a series of components and build parts of your application in isolation - just like a professional chef crafting each part of the meal. The book describes to how to structure your code base for reuse, and how to communicate the code's intent to other developers. You'll develop your components in isolation and test these building blocks for quality at a granular level. Then compose these components as building blocks in increasingly complicated features. Finally, you'll apply some strategies not directly related to code to ensure maximum quality and efficiency. With Modern Front-end Architecture, developers of all levels will learn strategies that they and their teams can leverage to be more productive. What You'll Learn Structure an application as a series of components Build a component library that others in an organization can leverage Ensure quality and accessibility at a component level rather than a page or app level Test code in a way that gives the maximum amount of confidence while providing an excellent developer experience Automate repeatable tasks Who This Book Is For Front end developers looking to maximize their code for reuse, quality, and shipping features quickly. Experienced developers will pick up new techniques that they can apply to their code base. Less experienced developers will be able to start applications off on the right foot.

While the subject of design patterns for software development has been covered extensively, little has been written about the power of the pattern format in interface design. 'A Pattern Approach to Interaction Design' remedies this situation, providing for the first time an introduction to the concepts, and application of patterns in user interface design.
The author shows interface designers how to use patterns to capture and structure user interface design knowledge from their projects, and how to use them to understand each other's design principles and solutions when working with clients and software developers. As an example, a ready-to-use pattern language for the design of interactive exhibits is presented.
