reactDoes React's Error Boundary catch dynamic chunk loading failures?
Handling Production Chunk Load Errors In a production React application using React.lazy for code splitting, dynamically imported modules are fetched as separate chunks. When a network failure or a missing asset occurs—such as a 404 error resulting from a deployment mismatch or an incorrect publicPath —the browser console typically reports an uncaught promis
Does Rollup preserve re-exported symbols when tree-shaking a library build?
Goal is to configure a Rollup library build that maximizes downstream tree-shaking while keeping the declared public API intact. Static tree-shaking relies on ES module syntax and accurate sideEffects metadata, and code splitting is driven by dynamic import() with manualChunks shaping. Output format choice between es and cjs changes interop helpers and expor
