Three lives saved by the Elixir; three lives bound by it. The Elixir entwines the lives of those it touches. Once upon a time, Kylene, Zelenka, and Devon tasted it and escaped death. None were left without scars. Now, a shocking message from the Ice Queen—one of Mother Nature’s higher beings—sends each survivor on a quest. Kylene travels to the frozen depths of Blanchardwood, Zelenka heads back to the wilds of Faway Forest, and Devon journeys to a reclusive mountain temple. The three paths converge in a war against an ancient and tricky foe. And even the Elixir cannot save everyone. The fate of the world balances on the edge of a sword, and the outcome depends on whether the survivors will sacrifice their second chances. Escape back into the world of the Great Peninsula in this much-anticipated sequel to the award-winning ELIXIR BOUND. Perfect for fans of the Thrones of Glass series by Sarah J. Maas.

Languages may come and go, but the relational database endures. Learn how to use Ecto, the premier database library for Elixir, to connect your Elixir and Phoenix apps to databases. Get a firm handle on Ecto fundamentals with a module-by-module tour of the critical parts of Ecto. Then move on to more advanced topics and advice on best practices with a series of recipes that provide clear, step-by-step instructions on scenarios commonly encountered by app developers. Co-authored by the creator of Ecto, this title provides all the essentials you need to use Ecto effectively. Elixir and Phoenix are taking the application development world by storm, and Ecto, the database library that ships with Phoenix, is going right along with them. There are plenty of examples that show you the basics, but to use Ecto to its full potential, you need to learn the library from the ground up. This definitive guide starts with a tour of the core features of Ecto - repos, queries, schemas, changesets, transactions - gradually building your knowledge with tasks of ever-increasing complexity. Along the way, you'll be learning by doing - a sample application handles all the boilerplate so you can focus on getting Ecto into your fingers. Build on that core knowledge with a series of recipes featuring more advanced topics. Change your pooling strategy to maximize your database's efficiency. Use nested associations to handle complex table relationships. Add streams to handle large result sets with ease. Based on questions from Ecto users, these recipes cover the most common situations developers run into. Whether you're new to Ecto, or already have an app in production, this title will give you a deeper understanding of how Ecto works, and help make your database code cleaner and more efficient. What You Need: To follow along with the book, you should have Erlang/OTP 19+ and Elixir 1.4+ installed. The book will guide you through setting up a sample application that integrates Ecto.

Book Description Running concurrent, fault-tolerant applications that scale is a very demanding responsibility. After learning the abstractions that Elixir gives us, developers are able to build such applications with inconceivable low effort. There is a big gap between playing around with Elixir and running it in production, serving live requests. This book will help you fll this gap by going into detail on several aspects of how Elixir works and showing concrete examples of how to apply the concepts learned to a fully fledged application. In this book, you will learn how to build a rock-solid application, beginning by using Mix to create a new project. Then you will learn how the use of Erlang's OTP, along with the Elixir abstractions that run on top of it (such as GenServer and GenStage), that allow you to build applications that are easy to parallelize and distribute. You will also master supervisors (and supervision trees), and comprehend how they are the basis for building fault-tolerant applications. Then you will use Phoenix to create a web interface for your application. Upon fnishing implementation, you will learn how to take your application to the cloud, using Kubernetes to automatically deploy, scale, and manage it. Last, but not least, you will keep your peace of mind by learning how to thoroughly test and then monitor your application. What you will learn Use Elixir tools, including IEx and Mix Find out how an Elixir project is structured and how to create umbrella applications Discover the power of supervision trees, the basis for fault-tolerance Create a Domain-Specifc Language (DSL) that abstracts complexity Create a blazing-fast web interface for your application with Phoenix Set up an automatic deployment process for the cloud Monitor your application and be warned if anything unexpected happens Who this book is for Mastering Elixir is for you if you have experience in Elixir programming and want to take it to the next level.

Take an epic journey in this award-winning young adult fantasy, winner of Best YA Book for the 2019 Connecticut Author Project! A young woman's quest to become the next guardian of a secret healing Elixir is perfect for fans of Shadow and Bone and The Lord of the Rings. Katora Kase isn't the firstborn son nor does she possess the type of magic that conjures spells or bewitches others. In the land of the Great Peninsula--an epic fantasy world ruled by the Great Mother Nature and her offspring--those things aren't a measure of one's worth. And what Katora does possess is the subtle magic that marks her as the next guardian of a secret healing Elixir that is her family's legacy. It is such a highly guarded secret that Katora doesn't know of its existence until a rare snowstorm blows through with a message for her father, the current guardian. Katora sets off on a quest into the wilds of Faway Forest to find the flowers that give the Elixir its potency. Even though she is accompanied by her sister, her brother, an old family friend, and a handsome mapmaker, she feels alone. For it is her decision alone whether or not to bind herself to the Elixir's magic to serve and protect it until a new guardian is chosen. The forest hosts many dangers, including wicked beings that will stop at nothing to gain power, but the biggest danger Katora faces is whether to give up a piece of her independence for the Elixir.

Elixir and Phoenix are generating tremendous excitement as an unbeatable platform for building modern web applications. For decades OTP has helped developers create incredibly robust, scalable applications with unparalleled uptime. Make the most of them as you build a stateful web app with Elixir, OTP, and Phoenix. Model domain entities without an ORM or a database. Manage server state and keep your code clean with OTP Behaviours. Layer on a Phoenix web interface without coupling it to the business logic. Open doors to powerful new techniques that will get you thinking about web development in fundamentally new ways. Elixir and OTP provide exceptional tools to build rock-solid back-end applications that scale. In this book, you'll build a web application in a radically different way, with a back end that holds application state. You'll use persistent Phoenix Channel connections instead of HTTP's request-response, and create the full application in distinct, decoupled layers. In Part 1, start by building the business logic as a separate application, without Phoenix. Model the application domain with Elixir functions and simple data structures. By keeping state in memory instead of a database, you can reduce latency and simplify your code. In Part 2, add in the GenServer Behaviour to make managing in-memory state a breeze. Create a supervision tree to boost fault tolerance while separating error handling from business logic. Phoenix is a modern web framework you can layer on top of business logic while keeping the two completely decoupled. In Part 3, you'll do exactly that as you build a web interface with Phoenix. Bring in the application from Part 2 as a dependency to a new Phoenix project. Then use ultra-scalable Phoenix Channels to establish persistent connections between the stateful server and a stateful front-end client. You're going to love this way of building web apps! What You Need: You'll need a computer that can run Elixir version 1.5 or higher and Phoenix 1.3 or higher. Some familiarity with Elixir and Phoenix is recommended.
