Session
This presentation shares our team's real-world experience migrating a production React application to Svelte 5 incrementally, without disrupting ongoing development. We faced mounting performance issues in our graphic editor and needed a framework with fine-grained reactivity. Rather than a risky complete rewrite, we developed bidirectional integration patterns that allowed React and Svelte components to coexist and communicate.
I'll demonstrate two key technical approaches: embedding Svelte 5 components within React applications and incorporating existing React components into new SvelteKit routes. Through code examples and performance comparisons, attendees will learn how to implement these patterns in their own projects, evaluate when migration makes business sense, and avoid common pitfalls we encountered.
This talk is ideal for frontend developers and technical leaders considering framework migrations but concerned about the risks of a complete rewrite. You'll leave with practical strategies for incremental adoption that balance technical improvements with business continuity.
