Agile Web Development with Rails 7

Description

Rails 7 completely redefines what it means to produce fantastic user experiences and provides a way to achieve all the benefits of single-page applications - at a fraction of the complexity. Rails 7 integrates the Hotwire frameworks of Stimulus and Turbo directly as the new defaults, together with that hot newness of import maps. The result is a toolkit so powerful that it allows a single individual to create modern applications upon which they can build a competitive business. The way it used to be. Ruby on Rails helps you produce high-quality, beautiful-looking web applications quickly - you concentrate on creating the application, and Rails takes care of the details. Rails 7 brings many improvements, and this edition is updated to cover the new features and changes in best practices. We start with a step-by-step walkthrough of building a real application, and in-depth chapters look at the built-in Rails features. Follow along with an extended tutorial as you write a web-based store application. Eliminate tedious configuration and housekeeping, seamlessly incorporate jаvascript, send and receive emails, manage background jobs with ActiveJob, and build real-time features using WebSockets and ActionCable. Test your applications as you write them using the built-in unit, integration, and system testing frameworks, internationalize your applications, and deploy your applications easily and securely. Rails 1.0 was released in December 2005. This book was there from the start, and didn't just evolve alongside Rails, it evolved with Rails. It has been developed in consultation with the Rails core team. In fact, Rails itself is tested against the code in this book. What You Need: All you need is a Windows, Mac OS X, or Linux machine to do development on. This book will take you through the steps to install Rails and its dependencies. If you aren't familiar with the Ruby programming language, this book contains a chapter that covers the basics necessary to understand the material in the book. Rails 7 introduced an entirely new way to produce state of the art user experiences comparable to the ones provided by Webpack and libraries such as React.js, but without the inherent complexity of adding in the complete Node.js ecosystem. "The best book to get started in the Rails world. A comprehensive, coherent, and concise overview of the Ruby on Rails framework. It treats learning in a gradual way, creating an application from scratch using the latest technologies" - Luis Miguel Cabezas Granado, Ruby on Rails and PHP developer at Junta de Extremadura (Spain) and PHP book writer at Anaya Multimedia Getting Started Installing Rails Installing on Windows Installing on macOS Installing on Linux Choosing a Rails Version Setting Up Your Development Environment Rails and Databases Instant Gratification Creating a New Application Hello, Rails!
