A complete guide to using IndexedDB

IndexedDB is a low-level API for client-side storage in web applications, offering a persistent NoSQL storage system within the browser that can accommodate various data types, including files, images, and structured data. It serves as a replacement for the deprecated WebSQL, providing greater storage capacity and supporting transactions, making it suitable for use cases like caching, PWAs, and gaming. The tutorial outlines the process of setting up IndexedDB for a web application, including database creation, data manipulation through API interactions, and implementing basic operations such as saving, retrieving, and deleting data in a to-do application. IndexedDB's limitations, such as scalability issues and synchronization challenges, are discussed, highlighting that while it is effective for smaller-scale applications, server-side databases or cloud-based solutions may be more appropriate for larger-scale applications. The tutorial is designed to help developers manage application data locally on the web using JavaScript, with practical examples and code snippets provided throughout.
