Discover best practices to create simple, robust, and scalable software solutions quickly and securely, and focus on what's important - the business and the end customer Key Features Discover strategies and tips for low-code and no-code development with the help of useful examples in this full-color guide Build enterprise-scale reactive web and mobile applications Explore the benefits of low-code development Book DescriptionOutSystems is a software development platform that speeds up the build phase by abstracting code and making almost everything visual. This means replacing textual language with visual artifacts that avoid lexical errors and speed up code composition using accelerators and predefined templates. The book begins by walking you through the fundamentals of the technology, along with a general overview of end-to-end web and mobile software development. You'll learn how to configure your personal area in the cloud and use the OutSystems IDE to connect with it. The book then shows you how to build a web application based on the best architectural and developmental practices in the market, and takes the same approach for the mobile paradigm. As you advance, you'll find out how to develop the same application, and the great potential of reusing code from one paradigm in another and the symbiosis between them is showcased.The only application that'll differ from the application in the exercise is the one used in business process technology (BPT), with a focus on a common market use case. By the end of this OutSystems book, you'll be able to develop enterprise-level applications on the web and mobile, integrating them with third parties and other systems on the market. You'll also understand the concepts of performance, security, and software construction and be able to apply them effectively. What you will learn Get to grips with the OutSystems infrastructure Develop reactive web and mobile applications in OutSystems using best practices in Service Studio Define and design Architecture Canvas (3-Layer Canvas) for your applications Integrate with external systems in OutSystems Enhance applications with BPT Manage and monitor your applications in the OutSystems infrastructure Who this book is forThis book is for back-end developers, tech leaders, UX/UI developers, frontend developers, (in general, full-stack developers), tech companies, and enterprises looking to learn how to develop web and mobile software quickly and disruptively by leveraging OutSystems, one of the most low-code platforms in the market. An IT background is not mandatory; however, experience in SQL, JavaScript, HTML, CSS, and C# is required to get started with this book.

Use a low-code programming approach to create event-driven applications from scratch by wiring together hardware devices, APIs, and online services Key Features Discover how you can automate the Internet of Things (IoT) without writing huge blocks of code Learn how to wire together flows using a browser-based visual editor Handle IoT data with little to no coding knowledge Book DescriptionNode-RED is a free and open source flow-based programming tool used to handle IoT data that allows programmers of any level to interconnect physical I/O, cloud-based systems, databases, and APIs to build web applications without code. Practical Node-RED Programming is a comprehensive introduction for anyone looking to get up to speed with the Node-RED ecosystem in no time. Complete with hands-on tutorials, projects, and self-assessment questions, this easy-to-follow guide will help you to become well versed in the foundations of Node-RED. You'll learn how to use Node-RED to handle IoT data and build web applications without having to write complex code. Once you've covered the basics, you'll explore various visual programming techniques and find out how to make sample flows as you cover web development, IoT development, and cloud service connections, and finally build useful real-world applications. By the end of this book, you'll have learned how to use Node-RED to develop a real-world application from scratch, which can then be implemented in your business. What you will learn Understand the history of Node-RED and why you need to learn a flow-based programming tool Use Node-RED to build Node.js-based applications Handle data for IoT devices using Node-RED flows Explore advanced Node-RED features such as connecting repositories and customizing the flow editor Find out what the MQTT protocol is and how it relates to Node-RED Create and publish your own nodes and flows using the Node-RED library Who this book is forThis Node-RED book is for web developers and IoT engineers with some background in JavaScript and Node.js. Although not necessary, familiarity with the concepts of electronics will help you to make the most out of this book.
