Reviewer scorecard
“Real-time reactivity without WebSocket boilerplate. Server functions co-located with schema definition is elegant.”
“webpack compatibility with Rust speed. The migration path from webpack is smoother than switching to Vite or Turbopack.”
“The DX is genuinely excellent. If your app needs real-time, Convex eliminates an enormous amount of complexity.”
“For webpack-heavy projects, Rspack provides the biggest speed improvement with the least migration effort.”
“Reactive backends that push data to clients will become the default. Convex is building that future now.”
“Rust-based JS tooling replacing JavaScript tooling is the trend. Rspack, Biome, and SWC prove it works.”
