Combining LiveView with Svelte for Advanced Web Applications

LiveView and Svelte are often seen as competing technologies for developing web applications, but Miguel Camba explains that they can work together seamlessly. Phoenix LiveView is known for facilitating the development of real-time applications, simplifying the synchronization between the data and UI, and handling user interactions effortlessly. However, interfaces that require advanced JavaScript features, such as animations or video and audio interactions, can be challenging to implement exclusively with LiveView. DockYard's experience with building a feature-rich WYSIWYG visual editor for BeaconCMS highlighted Svelte's capabilities in handling complex UI interactions. Initially, creating a standalone Svelte application and integrating it with a LiveView backend proved cumbersome due to the complexities of designing a suitable API. The solution came with the discovery of `live_svelte`, a library enabling Svelte components to be invoked from within a LiveView app. This approach allows developers to enjoy the benefits of both technologies: Svelte handles the demanding UI elements while LiveView manages state and events. Ultimately, this combination provided a highly productive development experience and negated the need for a REST API, leading to a more streamlined integration. The partnership of LiveView and Svelte is portrayed not as a rivalry, but as a formidable duo in the realm of web app development.
