JavaScript: Functional Programming for JavaScript Developers. Functional Programming for JavaScript Developers

Ved Antani, Simon Timms, Dan Mantyla

JavaScript is a high-level, dynamic, untyped, lightweight, and interpreted programming language and functional programming is a style that emphasizes and enables smarter code that minimizes complexity and increases modularity. It's a way of writing cleaner code through clever ways of mutating, combining, and using functions. And JavaScript provides an excellent medium for this approach. By learning how to expose JavaScript's true identity as a functional language, we can implement web apps that are more powerful, easier to maintain and more reliable.The java script: Functional Programming for JavaScript Developers course will take you on a journey to show how functional programming when combined with other techniques makes JavaScript programming more efficient.The first module Mastering JavaScript, stress on practical aspects of Javascript development like—Functions and Closures, Runtime debugging techniques, project layout, events and DOM processing, build tools, Object-oriented patterns, isomorphism—everything that a modern Javascript project would need.The second module, Mastering JavaScript Design Patterns - Second Edition, will explore how design patterns can help you improve and organize your JavaScript code. You’ll get to grips with creational, structural, and behavioral patterns as you discover how to put them to work in different scenarios. This updated edition will also delve into reactive design patterns and microservices as they are a growing phenomenon in the world of web development. It will also show you some advanced patterns, including dependency injection and live post processing.The third module, Functional Programming in JavaScript, will help you to write real-world applications by utilizing a wide range of functional techniques and styles. It explores the core concepts of functional programming common to all functional languages, with examples of their use in JavaScript.

Instant OpenLayers Starter. Web Mapping made simple and fast!

Alessio Di Lorenzo, Giovanni Allegri

OpenLayers is an open source JavaScript web mapping library distinguished from other alternatives, like Leaflet or Google Maps APIs, because of its huge set of components. Having being on the scene for a long time, users can benefit from a large set of resources and documentations, and a wide and actively supportive community.Instant OpenLayers Starter gives you the possibility to produce your first “real” web map without being an experienced programmer or a GIS specialist. It provides you with an overview of the most popular vector and raster data formats used to share spatial information on the Web. By the end of the book you will be able to amaze your boss with a brand new web map and a bag of skills to give life to your geodata.Instant OpenLayers Starter guides you through a fast and effective journey of web mapping, to discover how easy it is to put maps in your web projects, from simple base maps to interactive geo mash-ups, Google Maps, OpenStreetmap, GeoRSS, Panoramio, and your data. Starting with a lot of geo-information sources and a powerful library, we will explore how to manage maps inside web pages using basic third-party base maps to the overlay of re-projected vector data, going through styling thematic data and data interaction.

RSpec Essentials. Develop testable, modular, and maintainable Ruby software for the real world using RSpec

Mani Tadayon

This book will teach you how to use RSpec to write high-value tests for real-world code. We start with the key concepts of the unit and testability, followed by hands-on exploration of key features. From the beginning, we learn how to integrate tests into the overall development process to help create high-quality code, avoiding the dangers of testing for its own sake.We build up sample applications and their corresponding tests step by step, from simple beginnings to more sophisticated versions that include databases and external web services. We devote three chapters to web applications with rich JavaScript user interfaces, building one from the ground up using behavior-driven development (BDD) and test-driven development (TDD).The code examples are detailed enough to be realistic while simple enough to be easily understood. Testing concepts, development methodologies, and engineering tradeoffs are discussed in detail as they arise. This approach is designed to foster the reader’s ability to make well-informed decisions on their own.

BPEL and Java Cookbook. Written by an SOA guru to help you orchestrate web services, the 100 recipes in this book will make integrating Java and BPEL a smooth process. Using the examples you'll avoid common problems and learn sophisticated techniques

Jurij Laznik

The Business Process Execution Language (BPEL) has become the de-facto standard for orchestrating web services. BPEL and web services are both clamped into Service-oriented Architecture (SOA). Development of efficient SOA composites too often requires usage of other technologies or languages, like Java. This Cookbook explains through the use of examples how to efficiently integrate BPEL with custom Java functionality.If you need to use BPEL programming to develop web services in SOA development, this book is for you.BPEL and Java Cookbook will show you how to efficiently integrate custom Java functionality into BPEL processes. Based on practical examples, this book shows you the solutions to a number of issues developers come across when designing SOA composite applications. The integration between the two technologies is shown two-fold; the book focuses on the ways that Java utilizes the BPEL and vice-versa.With this book, you will take a journey through a number of recipes that solve particular problems with developing SOA composite applications. Each chapter works on a different set of recipes in a specific area. The recipes cover the whole lifecycle of developing SOA composites: from specification, through design, testing and deployment.BPEL and Java Cookbook starts off with recipes that cover initiation of BPEL from Java and vice-versa. It then moves on to logging and tracing facilities, validation and transformation of BPEL servers, embedding of third-party Java libraries into BPEL. It also covers manipulation with variables in BPEL different techniques of Java code wrapping for web service usage and utilization of XML fa?ßades.After reading BPEL and Java Cookbook you will be able to circumvent many of the issues that developers experience during SOA composite application development.
