This Week In React-Native #137: Expo Code Elimination, Monorepo, Hermes, Chain React, EAS, Skia, Expo Router, VisionCamera, React-Native-Graph
📜 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.

Alternatives for realtime offline-first JavaScript applications
I think that my Storage implementation that is built-in into JavaScript in QuickJS and Sciter is still unbeatable as an integrated JS Storage solution:
-
Sciter, the 5 MB Electron alternative, has switched to JavaScript
"custom version of React he publishes..."
It is not a a custom version of React but rather extension of DOM model by just these:
1. Native JSX support. In Sciter QuickJS was extended to support JSX literals out of the box: https://github.com/c-smile/quickjspp/blob/master/quickjs-jsx...
2. Native methods:
- Element.patch(...JSX expression...) - native VDOM reconciliation implementation. -
Txiki.js: Tiny JavaScript runtime built with QuickJS and libuv
In fact 1.8 Mb is quite a lot for QuickJS.
Whole Sciter engine that includes as QuickJS as HTML/CSS engines is about 6 Mb.
My port of QuickJS [1] that also includes persistent storage (think of MongoDB built into JS) is 736 Kb on Windows.

Mongita is to MongoDB as SQLite is to SQL
I've added built-in persistence to QuickJS: https://github.com/c-smile/quickjspp/blob/master/storage/doc/introduction.md

Show HN: Svelte NodeGUI, a lightweight Electron alternative with native UI
I might go a little offtopic here. Any plans to integrate https://github.com/c-smile/quickjspp. That way you can target mobile platforms too. QT supports mobiles well
As for desktop only this is great. Great work. Many people are commenting on NodeGUI only. They have forgotten to mention how Svelte also contribytes to saving memory footprint and cpu cycles over other frameworks with a much easier way to write apps. Add a small learning curve to that.
