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.

This book will show you how monitoring containers and keeping a keen eye on the working of applications helps improve the overall performance of the applications that run on Docker. With the increased adoption of Docker containers, the need to monitor which containers are running, what resources they are consuming, and how these factors affect the overall performance of the system has become the need of the moment.This book covers monitoring containers using Docker's native monitoring functions, various plugins, as well as third-party tools that help in monitoring. Well start with how to obtain detailed stats for active containers, resources consumed, and container behavior. We also show you how to use these stats to improve the overall performance of the system. Next, you will learn how to use SysDig to both view your containers performance metrics in real time and record sessions to query later. By the end of this book, you will have a complete knowledge of how to implement monitoring for your containerized applications and make the most of the metrics you are collecting

ElasticSearch is a distributed search server similar to Apache Solr with a focus on large datasets, a schema-less setup, and high availability. This schema-free architecture allows ElasticSearch to index and search unstructured content, making it perfectly suited for both small projects and large big data warehouses with petabytes of unstructured data.This book is your toolkit to teach you how to keep your cluster in good health, and show you how to diagnose and treat unexpected issues along the way. You will start by getting introduced to ElasticSearch, and look at some common performance issues that pop up when using the system. You will then see how to install and configure ElasticSearch and the ElasticSearch monitoring plugins. Then, you will proceed to install and use the Marvel dashboard to monitor ElasticSearch. You will find out how to troubleshoot some of the common performance and reliability issues that come up when using ElasticSearch. Finally, you will analyze your cluster’s historical performance, and get to know how to get to the bottom of and recover from system failures.This book will guide you through several monitoring tools, and utilizes real-world cases and dilemmas faced when using ElasticSearch, showing you how to solve them simply, quickly, and cleanly.

Moodle gives you the power to create and customize feature-rich plug-ins. If you can write Moodle plug-ins, you can make it do just about anything. From making the site easier to administer, to new features, to completely changing the way it looks; plug-ins are the method Moodle offers to customize and extend its functionality. This book will show you how to build all sorts of Moodle plug-ins: admin plug-ins, Blocks, Activities, Grading components, Reports, Fliters that change the way your site works and looks. You will develop standard Moodle plug-ins such as Activities, Filters, and Blocks by creating functioning code that you can execute in your own Moodle installation. Writing modular plug-ins for Moodle will be a large focus of this book.This book will take you inside Moodle and provide you with the ability to develop code the “Moodle way”.This book will expose you to all of the core code functions in Moodle, in a progressive, understandable way. You will learn what libraries are available, what the API calls are, how it is structured and how it can be expanded beyond the plug-in system.You will begin by getting an understanding of the basic architecture that Moodle uses to operate in. Next you will build your first plug-in; a block. You will carry on building other Moodle plug-ins, gaining knowledge of the “Moodle way” of coding, before plunging deeper into the API and inner libraries. Lastly, you will learn how to integrate Moodle with other systems using a variety of methods.When you have completed, you will have a solid understanding of Moodle programming and knowledge of how to extend its functionality in whatever way you want.

Educators use the Moodle web application to create effective online learning sites. Creating such learning environments that suit Design and Technology subjects requires understanding and implementation of both basic and advanced Moodle features.This book takes a detailed look at Moodle features with examples of how to fully support the Design and Technology curricula using Moodle. It will guide you to incorporate specific modules and blocks to enhance learning as well as allow detailed tracking of performance by using formative and summative assessment tools with ease.We start with setting up a very basic Moodle course for Design and Technology, and then set up some basic resources and some interactive material. You will customize your own courses and create a course for each of the key areas of the DT subjects and add material to them. We will create some basic reporting and assessment tools and enhance the look of the course. We will use Moodle's detailed and sophisticated gradebook to assess your student s ' learning progress in activities from an assignment to an offline activity. Then we will support students in designing a product or trying a new recipe in food technology in market research to find out exactly what the public wants in relation to their product, by designing a questionnaire. We will allow product design or resistant material students use the HTML features of the questionnaire module to incorporate images into the questions to make it clearer to respondents what it is they are trying to make and sell.We will allow students in construction to gather and organize their research material in a great deal of detail and also allow them to better understand their target market and the materials used in their construction through detailed questioning. We will allow food technology students to discuss and receive constructive feedback on food products that contribute to health issues that will enable them to make informed decisions and therefore better quality products. Then we explore several components within Moodle's core functionality and some third-party sources to display the progress of the student's work and development. We then have an overview of the different design portfolios available. Finally we look at additional ways to enhance the teaching and learning of D ' T with Moodle using third-party modules and add-ons.
