Vue.js is a versatile and reactive framework suitable for building web applications, including spatial applications that utilize CARTO's features. CARTO provides essential backend functionality for spatial apps, allowing developers to focus on frontend user experience. The platform integrates seamlessly with Vue.js, and deck.gl is recommended for visualization capabilities. An example application demonstrates best practices for building scalable spatial apps with Vue.js and CARTO. The example uses well-supported open-source libraries like Vue Material, Vuex, Vue Router, Apache ECharts, and Turf.js to manage state, navigation, and spatial analysis. A layerManager module handles layers, and state management is achieved using Vuex. To get started, developers should read the guide and contact the platform if needed.
