Why I Replaced Polling with Orbistats' WebSocket API (With Before/After Latency Numbers)

·1 views

Polling is the first thing everyone builds and the last thing anyone is proud of. Here's the migration, the code, and a way to measure your own before/after instead of trusting mine.

When I first ran into Web3, CryptoKitties were a thing, NFTs were everywhere, and DeFi was exploding.
