Learn advanced techniques and best practices of Angular programming for building enterprise web applications Key Features Get familiar with the core concepts of Angular. Discover best practices, tips, and tricks while working with Angular. Learn how to architect data driven web applications. Explore methods to pass data between components in Angular. Learn how to deploy and secure your Angular application. Description Angular is a Single Page Application (SPA) development framework open-sourced by Google. The Angular framework is written in TypeScript language, which enables a web developer to write JavaScript code in Object-Oriented fashion. TypeScript makes it easier to build a client-side web application with classes, interfaces, generics, inheritance, and other Object-Oriented features. TypeScript compiler takes care of transpiling these features into native JavaScript. Angular is a framework that comes with Dependency Injection, HTTP communication, Forms, and other features out of the box. This book will leverage on your prior programming knowledge to learn Angular. Microsoft .Net stack, C#, Windows Forms, WPF, ASP.NET have been widely used for developing desktop and web applications. We shall be referring to concepts from these technologies with Angular whenever applicable, thus having prior experience would be a great advantage. This book takes you from the basics of TypeScript language to building modular and robust enterprise web applications and deployment. What you will learn Learn how to orchestrate complex Angular applications. Get to know more about Dependency Injection in depth. Learn how to build template and dynamic forms in Angular. Learn how to use Angular routes in an application. Learn how to communicate with backend services using HTTP. Who this book is for This book is for readers who want to learn Angular. Having a basic Object-Oriented programming knowledge, programming experience with C#.Net/Java, and hands-on web development experience would be an added advantage. Table of Contents 1. Typescript – the underdog 2. Hello, Angular! 3. Building small and simple 4. Data Binding and Pipes 5. NgModule - in depth 6. Dependency Injection and Services 7. Building forms 8. Communication within Components 9. Consuming HTTP Resources 10. Routing Angular application 11. Deployment and tools About the Author Balram Chavan is a software professional having 11+ years of relevant experience working in cross domains. He has been awarded with GitHub Developer Program Membership for his contribution to open source world. He also contributes to multiple technology blogs and forums. Balram has also published many npm.js packages for Angular framework. LinkedIn Profile: https://www.linkedin.com/in/balram-chavan/
Learn to be a Python expert in ten easy lessons! Key Features Acquire knowledge of Python programming simply and easily. Learn about object-oriented programming and how it applies to Python. Make a splash with list comprehensions, generators, and decorators. Learn about file processing with Python, and how it makes JSON easy to deal with. Work with dictionaries and sets quickly and easily. Learn about what others have made available in the Python world. Pick up tricks and tips that will make you look like a Python expert in no time. Description This book is intended for the professional programmer who wants to learn Python for their place of business, or simply to extend their knowledge. You will learn the basics of the language--from how to define variables and implement looping and conditional constructs, to working with existing code. Once we have established the baseline for writing code in Python, you’ll learn how to create your own functions and classes, how to extend existing code, and how to work with Python-specific things like comprehensions and generators. With a solid foundation, you will then move on to learn about the existing Python libraries, called packages, and how to use them, as well as discovering little tips and tricks that will make you a hit with all the programmers at work, and really aid you in nailing that programming interview. What will you learn By the time you have finished this book, you will know enough to write complex Python programs and work with existing Python code. You will find out about the packages that make Python one of the most popular programming languages and will understand the “Pythonic” way of thinking and programming. Who this book is for This book is designed for programmers who have experience in at least one programming language. No prior Python experience is necessary, but it is assumed that you understand the basics of loops, conditionals and object-oriented constructs, such as classes. You should have or have access to a system that runs Python 3 (any version). Table of Contents 1. The history and installation of Python 2. Python types and constructs 3. The Nuts and Bolts 4. Structuring your Python projects 5. Object-oriented programming with Python 6. Advanced manipulations 7. File input and output 8. Imports and Exports 9. Miscellaneous 10.
