Building Vue.js Applications with GraphQL. Develop a complete full-stack chat app from scratch using Vue.js, Quasar Framework, and AWS Amplify

Heitor Ramon Ribeiro

Since its release by Facebook in 2012, GraphQL has taken the internet by storm. Huge companies such as Airbnb and Audi have started to adopt it, while small to medium-sized companies are now recognizing the potential of this query-based API.GraphQL may seem strange at first, but as you start to read about and experience more of it, you won’t want to use REST APIs anymore.With the recipes in this book, you will learn how to build a complete real-time chat app from scratch. Starting by creating an AWS Amplify environment, you will delve into developing your first GraphQL Schema. You will then learn how to add the AppSync GraphQL client and create your first GraphQL mutation. The book also helps you to discover the simplicity and data fetching capabilities of GraphQL that make it easy for front-end developers to communicate with the server. You will later understand how to use Quasar Framework to create application components and layouts. Finally, you will find out how to create Vuex modules in your application to manage the app state, fetch data using the GraphQL client, and deploy your application to the web.By the end of this book, you’ll be well versed in proof-of-concept full-stack applications that explore the power of GraphQL with AWS Amplify, and you'll be able to use Quasar Framework to create your Vue applications.

Clean Code in C#. Refactor your legacy C# code base and improve application performance by applying best practices

Jason Alls

Traditionally associated with developing Windows desktop applications and games, C# is now used in a wide variety of domains, such as web and cloud apps, and has become increasingly popular for mobile development. Despite its extensive coding features, professionals experience problems related to efficiency, scalability, and maintainability because of bad code. Clean Code in C# will help you identify these problems and solve them using coding best practices.The book starts with a comparison of good and bad code, helping you understand the importance of coding standards, principles, and methodologies. You’ll then get to grips with code reviews and their role in improving your code while ensuring that you adhere to industry-recognized coding standards. This C# book covers unit testing, delves into test-driven development, and addresses cross-cutting concerns. You’ll explore good programming practices for objects, data structures, exception handling, and other aspects of writing C# computer programs. Once you’ve studied API design and discovered tools for improving code quality, you’ll look at examples of bad code and understand which coding practices you should avoid.By the end of this clean code book, you’ll have the developed skills you need in order to apply industry-approved coding practices to write clean, readable, extendable, and maintainable C# code.

Modular Programming with JavaScript. Modularize your JavaScript code for better readability, greater maintainability, and enhanced testability

Sasan Seydnejad, Shamasis Bhattacharya

Programming in the modular manner is always encouraged for bigger systems—it is easier to achieve scalability with modular programming. Even JavaScript developers are now interested in building programs in a modular pattern. Modules help people who aren’t yet familiar with code to find what they are looking for and also makes it easier for programmers to keep things that are related close together.Designing and implementing applications in a modular manner is highly encouraged and desirable in both simple and enterprise level applications. This book covers some real-life examples of modules and how we can translate that into our world of programming and application design. After getting an overview of JavaScript object-oriented programming (OOP) concepts and their practical usage, you should be able to write your own object definitions using the module pattern. You will then learn to design and augment modules and will explore the concepts of cloning, inheritance, sub-modules, and code extensibility. You will also learn about SandBoxing, application design, and architecture based on modular design concepts. Become familiar with AMD and CommonJS utilities. By the end of the book, you will be able to build spectacular modular applications in JavaScript.

Python 2.6 Graphics Cookbook. Learn how to use Python’s built-in graphics capabilities to create static and animated graphics for a range of real-world purposes. Over 100 recipes take you from basic shape creation to developing interactive GUIs

Mike Ohlson de Fine, Michael J Ohlson

Python is a great object-oriented and interactive programming language that lets you develop graphics, both static and animated, using built-in vector graphics functions that are provided with Python.Python 2.6 Graphics Cookbook is a collection of straightforward recipes and illustrative screenshots for creating and animating graphic objects using the Python language. This book makes the process of developing graphics interesting and entertaining by working in a graphic workspace without the burden of mastering complicated language definitions and opaque examples.If you choose to work through all the recipes from the beginning, you will learn to install Python and create basic programs for making lines and shapes using the built-in Tkinter module. The confusing topic of color manipulation is explored in detail using existing Python tools as well as some new tools in the recipes. Next you will learn to manipulate font size, color, and placement of text as placing text exactly where you want on a screen can be tricky because font height, inter-character spacing, and text window dimensions all interfere with each other. Then you will learn how to animate graphics, for example having more than one independent graphic object co-exist and interact using various Python methods.You will also learn how you can work with raster images, such as converting their formats using the Python Imaging Library. Next you will learn how you can combine vector images with raster images so that you can animate the raster images with ease. You will also walk through a set of recipes with the help of which you can handle and manipulate blocks of raw data that may be hundreds of megabytes in size using datastreams, files, and hard drives. You will also learn how you can use Inkscape to dismantle existing images and use parts of them for your own graphics and Python programs. At the end of the book you will learn how you can create GUIs for different purposes.
