Web Application Design Patterns

Ever notice that—in spite of their pervasiveness—designing web applications is still challenging? While their benefits motivate their creation, there are no well-established guidelines for design. This often results in inconsistent behaviors and appearances, even among web applications created by the same company. Design patterns for web applications, similar in concept to those for web sites and software design, offer an effective solution. In Web Application Design Patterns, Pawan Vora documents design patterns for web applications by not only identifying design solutions for user interaction problems, but also by examining the rationale for their effectiveness, and by presenting how they should be applied. Design interfaces faster, with a better rationale for the solutions you choose. Learn from over more than 100 patterns, with extensive annotation on use and extension. Take a short-cut into understanding the industry with more than 500 full-color screenshots.

Apply design patterns to solve problems in software architecture and programming using C# 7.x and .NET Core 2 Key FeaturesEnhance your programming skills by implementing efficient design patterns for C# and .NETExplore design patterns for functional and reactive programming to build robust and scalable applicationsDiscover how to work effectively with microservice and serverless architecturesBook Description Design patterns are essentially reusable solutions to common programming problems. When used correctly, they meet crucial software requirements with ease and reduce costs. This book will uncover effective ways to use design patterns and demonstrate their implementation with executable code specific to both C# and .NET Core. Hands-On Design Patterns with C# and .NET Core begins with an overview of object-oriented programming (OOP) and SOLID principles. It provides an in-depth explanation of the Gang of Four (GoF) design patterns such as creational, structural, and behavioral. The book then takes you through functional, reactive, and concurrent patterns, helping you write better code with streams, threads, and coroutines. Toward the end of the book, you’ll learn about the latest trends in architecture, exploring design patterns for microservices, serverless, and cloud native applications. You’ll even understand the considerations that need to be taken into account when choosing between different architectures such as microservices and MVC. By the end of the book, you will be able to write efficient and clear code and be comfortable working on scalable and maintainable projects of any size. What you will learnMake your code more flexible by applying SOLID principlesFollow the Test-driven development (TDD) approach in your .NET Core projectsGet to grips with efficient database migration, data persistence, and testing techniquesConvert a console application to a web application using the right MVPWrite asynchronous, multithreaded, and parallel codeImplement MVVM and work with RxJS and AngularJS to deal with changes in databasesExplore the features of microservices, serverless programming, and cloud computingWho this book is for If you have a basic understanding of C# and the .NET Core framework, this book will help you write code that is easy to reuse and maintain with the help of proven design patterns that you can implement in your code.

Inhaltsangabe:Abstract: In 1994 the Gang of Four, consisting of Erich Gamma, Richard Helm, Ralph Johnson and John Vlissides, published the book Design Pattern - Elements of Reusable Object-Oriented Software. Within that book the four information scientists described 23 design patterns, which they classi?ed into the categories Creational Design Pattern, Structural Design Pattern and Behavioral Design Pattern. Even though design patterns exist since 15 years at present, they have not lost relevance. Due to new concepts the usage of design patterns within web application is increasing. Meanwhile all 23 established design patterns are available as PHP implementations. Aside web languages like AJAX, JavaScript, XHTML and CSS also appreciate the strength of design patterns. At first web languages like AJAX, PHP, et cetera will be analyzed if they qualify for the usage of design patterns. At second the usage of design patterns within open source web applications like Typo3, Joomla, Wordpress, et cetera will be examined. At third various web developers of 1&1, web.de, Telekom, et cetera will be interviewed to investigate if and in which amount design patterns are used by companies. Intention of this thesis is to determine the relevance of design pattern within web applications. Thereby advantages will also be shown like disadvantages. Also the question, if design patterns should be used by default or only if the concerning project reached a specific size, will be answered.

Technology is meant to make life easier and to raise its quality. Our interaction with technology should be designed according to human needs instead of us being required to adapt to technology. Even so, technology may change quickly and people and their habits change slowly. With the aim of supporting user acceptance of iTV, the focus of this book is on the usability of iTV applications. A method for developing interaction design patterns especially for new technologies is presented for the first time. The main characteristics covered in this new approach are: systematic identification of recurrent design problems; usability as a quality criterion for design solutions; integration of designers into the pattern development process including identification of designers' needs, and iterative evaluation and optimisation of patterns to encourage designers to accept and use them; usability testing to identify proven design solutions and their trade-offs; presentation of specific design guidelines.
