JSConf Chile Day 1
summary
Benchmarks compare binary formats (MessagePack, Protocol Buffers, Avro) showing much smaller payloads than JSON and differing strengths for RPC: Protocol Buffers give tiny, fast RPC payloads while Avro can win throughput tests. Node 18 additions covered an integrated test runner, watch, stream map/filter, argument parser and undici HTTP client. A LiFi prototype using Arduino and Johnny-Five demonstrated visible‑light byte transfer (demo speeds ~60–600 ms per character); a web performance segment reported real‑world issues like deferred LCP images and very low use of priority hints, recommending real‑user measurement, CDNs and proper caching.
