Summary/Abstract: The article addresses the development of a cross-platform application using the Ionic hybrid web development framework for the client-side and the NoSQL Firebase database for implementing the server-side. The modern market often requires IT specialists to quickly develop high-quality solutions designed to solve specific business problems. Relevant tasks include developing a client-side application that works across multiple devices simultaneously and minimizing the server-side by leveraging cloud services that provide Database as a Service (DBaaS). Hybrid web development allows for the simultaneous creation of web and mobile applications, such as for Android and iOS, with the Ionic framework being one of the most popular solutions for hybrid development. This framework enables the development of cross-platform applications using web development tools, namely HTML, CSS, and JavaScript, and integrates with three of the most common web frameworks: Angular, React, and Vue. Additionally, it includes its own set of native visual components. Firebase is a popular tool for quickly building applications without managing infrastructure. It provides a scalable cloud-based NoSQL database for real-time data storage and synchronization. Built on Google's infrastructure, Firebase automatically scales. One of the key challenges when using NoSQL databases is ensuring data integrity during data deletion and editing operations. Using a cross-platform application developed by the authors to manage a small coffee shop's website as an example, this article proposes algorithms to ensure data integrity when using the Firebase NoSQL database. During the development of the application, the RxJS library was used to support real-time functionality, utilizing the Observer pattern to simplify the handling and composition of asynchronous or callback code.
