Mongoose for Application Development. Mongoose streamlines application development on the Node.js stack and this book is the ideal guide to both the concepts and practical application. From connecting to a database to re-usable plugins, it's all here

Simon Holmes

Mongoose is all about putting the data model where it should be: in your application. You can control everything from within your application in JavaScript, eliminating the need to work with the database or a separate management system.Mongoose for Application Development is a practical, hands-on guide that takes you from installing the technology stack through the steps of developing a web application. It covers the key features of Mongoose and how to use them to rapidly develop a Node.js and MongoDB application.This book introduces the full technology stack of Node.js, MongoDB, Express, and Mongoose. It will take you through the process of building an application on this stack with a focus on how Mongoose makes the process quicker and easier.You will see how Mongoose removes a layer of complexity when dealing with MongoDB whilst giving you more control over your data from your application. You will learn how to define schemas and models for your data in JavaScript. Using these schemas and models, you will learn how to build the cornerstone of any web application that will include CRUD operations (creating, reading, updating, and deleting data). If you want to learn how to build applications quickly and efficiently using Node.js, then Mongoose and this book are ideal for you.Using practical examples throughout, Mongoose for Application Development not only teaches you about the concepts of Mongoose, but walks through how to use them to build a real-life application.

Unity 2021 Shaders and Effects Cookbook. Over 50 recipes to help you transform your game into a visually stunning masterpiece - Fourth Edition

John P. Doran

Shaders enable you to create powerful visuals for your game projects. However, creating shaders for your games can be notoriously challenging with various factors such as complex mathematics standing in the way of attaining the level of realism you crave for your shaders.The Unity 2021 Shaders and Effects Cookbook helps you overcome that with a recipe-based approach to creating shaders using Unity. This fourth edition is updated and enhanced using Unity 2021 features and tools covering Unity's new way of creating particle effects with the VFX Graph. You'll learn how to use VFX Graph for advanced shader development. The book also features updated recipes for using Shader Graph to create 2D and 3D elements. You'll cover everything you need to know about vectors, how they can be used to construct lighting, and how to use textures to create complex effects without the heavy math. You'll also understand how to use the visual-based Shader Graph for creating shaders without any code.By the end of this Unity book, you'll have developed a set of shaders that you can use in your Unity 3D games and be able to accomplish new effects and address the performance needs of your Unity game development projects.
