This book will show you how to harness the power of Appsmith, an open-source low-code platform with a large set of integration tools and an active community.

The book begins with an introduction to Appsmith and its features. As you explore the platform, you will learn about widgets, UI Canvas, and data stores, among other things. Authors Rahul Sharma and Rajat Arora then show you how to build customizations and navigation workflows, as well as how to handle error handling, debugging, and troubleshooting with Appsmith. You will also learn efficient monitoring and authentication for deploying production-ready systems. Low-Code Development with AppSmith provides examples, realistic scenarios, and explanations of the tools you'll need to build successful low-code apps, helping you gain practical skills.

Upon completing this book, you will be able to use Appsmith to build low-code solutions that suit your business requirements.

What You Will Learn:
Understand low-code development and the factors driving its adoption
Solve your business's most pressing issues with Appsmith
Gain an understanding of the key concepts of app development, such as data management, APIs, troubleshooting, and debugging
Model different design patterns for low-code development

When developing applications in Appsmith, you’ll often interact with jаvascript methods that are asynchronous (async) or synchronous (sync). Understanding the difference between these two types of methods is vital to the performance and functionality of your applications. jаvascript is single-threaded, meaning it can only perform one operation at a time. Sync methods are executed sequentially, blocking the execution thread until they are completed. This might be fine for simple, quick operations, but for tasks that take longer to execute (like network requests, file operations, or database queries), using sync methods can lead to an unresponsive or slow application. This is where async methods come in.

Async methods are non-blocking; they allow jаvascript to continue executing other code while the async operation is being processed. When the async operation is completed, a callback function is executed to handle the result. In jаvascript, async functions usually return a promise, which is an object that represents the eventual completion (or failure) of an asynchronous operation and its resulting value.

Appsmith provides a variety of widgets, each with different properties, to help developers design intuitive and efficient user interfaces. Understanding when and where to use sync and async methods with these widget properties is crucial for a smooth and responsive app experience.

Who This Book Is For:
Anyone interested in designing technical solutions with minimal programming. This book assumes a basic understanding of object-oriented programming and jаvascript.
