TFW you are tired of reusing always the same pattern to enable/disable debugging and you'd like to have some tiny tool to deal with it ... because it's an awesome pattern 🥰 github.com/WebReflectio...

if you have any interest in a possible future where JSON can serialize and deserialize more than just 5 types, follow this space/proposal 👋 es.discourse.group/t/jsonregist...

JSONRegistry - Allows branded instances in regular JSON

I've written so many serializer/encoder/decoder but I feel like going back to basics every single time, although this time I think I've nailed a prototype that works well with both native JSON API and...

getOrInsertComputed in Map/WeakMap is actually pretty cool, it simplifies caching a lot and it's not limited to synchronous values, example: const cache = new Map; const asText = async page => fetch(page).then(r => r.text()); await cache.getOrInsertComputed('index', asText);

whenever I read posts like "don't us JS Array reduce" I'm like: const gcd = (a, b) => (b ? gcd(b, a % b) : a); const lcm = (a, b) => (a * b) / gcd(a, b); [2, 3, 4, 5].reduce((p, c) => lcm(p, c)); // 60 [12, 18, 36].reduce((p, c) => gcd(p, c)); // 6 I mean ... 🤷

apparently my account has been compromised on bsky ... it's honestly the only service out there that never offered me (until today), or enforced, 2FA, it was kinda inevitable, yet my deepest apologies if my account spam/scammed you by any mean 🙏

in case anyone is interested, I am documenting what I am working on regularly (each week) with links and every other detail needed to understand where I come from and where I am heading. This is OSS to me, nobody can blame me for not being transparent 😇 github.com/WebReflectio...

in today "nobody asked for it, thanks!" news, the recent issue filed against flatted module (333M downloads per months) kinda "scared" me to the point I rewrote the whole thing in a binary friendly format: flatted-view: please test it, thank you 🙏 github.com/WebReflectio...

in today "good morning OSS" news, @golang receives its first *flatted* implementation, making flatted now usable in JS, TS, Python, PHP and, ultimately Go 🥳 Huge thank to Harald Fielker for helping out (writing everything), lets' go beyond 300M Downloads! github.com/WebReflectio...

today I’ve quickly glued together two libraries that makes custom elements without shadow dom as fast and as simple as it can get and for every browsers … after reading the N post about ShadowDOM issues with CSS. You can stop that madness already 👋 github.com/WebReflectio...

JS Proxy are wonderful, penalized by TS inability to actually understand/deal with these but the things that these unlock are incredible! It might be a niche use case but if you need cached results, here my next go-to library: github.com/WebReflectio...

if you use Proxies and you bind methods returned on `get` trap, please read carefully why that's a bad idea and how to avoid doing that: es.discourse.group/t/reflect-se...

I swear I read binding before and because that’s a delicate topic I’d like to explain to future readers how not to bind methods because: obj.method === obj.method should always be true obj.method in...
