Lovefield - Relational Database for Web Apps

Lovefield is a relational database written entirely in JavaScript, designed for web applications. It provides a SQL-like query API, leveraging IndexedDB for persistent storage in the browser environment. Developed by Google, the package reached its last published version, 2.1.12, in February 2017. While the GitHub repository saw minor updates until January 2023, active feature development and official maintenance appear to have ceased significantly earlier, around 2015-2017, as indicated by project videos and publishing dates. Lovefield offers cross-browser compatibility (supporting older versions of Chrome, Firefox, IE, and Safari) but explicitly does not support Node.js due to its reliance on IndexedDB. Its key differentiators were bringing a relational model and SQL-like syntax to client-side data management before more modern alternatives emerged, offering atomic transactions and a query optimizer.
