What happens when a web dev goes down the React Native rabbit hole with a weekend hack project? You get a custom file-based router built from scratch, with suspense and error handling, and some clever use of Metro internals.
In this talk from the React Universe Meetup in Wrocław (April 2024), Szymon Chmal, Senior Software Engineer at Callstack, walks through how curiosity led him to explore file routing in React Native. Along the way, he uncovered undocumented Metro APIs, tackled dynamic imports, and discovered ways to replicate familiar patterns from Next.js, all with a surprisingly lean setup.
Expect some laughs, real talk about dev pain points, and a ton of practical insights.
