A performant way to use PouchDB@7 on React Native in 2022
Oscar Franco created a great SQLite driver react-native-quick-sqlite, which provides a low-level API to execute SQL queries, fast bindings via JSI. JSI has a smaller overhead than the traditional RN bridge's. So, this is much faster than react-native-sqlite-2, which I made to get PouchDB to work on RN before.

đź“ś I made JSON.parse() 2x faster: Radek proposes to improve the performance of Hermes by using very fast C++ libs based on SIMD instructions. Interesting to read even if you don't use React-Native. Ongoing discussions on the Hermes PR.

I made JSON.parse() 2x faster
Thanks! There's a preliminary PR with a discussion here: https://github.com/facebook/hermes/pull/933 (and broader context here: https://github.com/facebook/hermes/issues/811 ). But we'll see if there's any interest on Hermes' side to merging it. They definitely want to improve the parser, but it's unclear to me if they want to take on the simdjson/simdutf dependencies.

Don't pay for painfully slow React Native iOS builds anymore.
💉 Building and injecting a JS bundle a basic concept: If the native code wasn’t changed, simply create JS bundle and inject it into the precompiled application. (You must take an extra step to convert a js file to bytecode if you use the Hermes js engine.)
