A basic example of using lighthouse , puppeteer, and jest to do performance testing. https://github.com/justinribeiro/lighthouse-jest-example
Got around to updating my blog-pwa project from @polymer 3 to LitElement, @workboxjs, and @RollupJS. Amazingly smooth and web perf is nice little bump on 3G.
My love of developing film knows no bounds. Developing 4x5 Kodak Super-XX film pack with an SP-445. https://justinribeiro.com/chronicle/2019/04/08/developing-4x5-kodak-super-xx-film-pack-with-an-sp-445/
Working around polymer modulizer errors with object rest spread properties. Because sometimes you just have to.
I'm really happy to see long task surface on the performance panel in M74. 🎉 Incredibly useful. https://developers.google.com/web/updates/2019/03/devtools#longtasks
Fantastic piece by Jamie Alberico on making sense of
Lighthouse perf numbers. If you're not measuring your web perf, you're doing your users a disservice. https://www.searchenginejournal.com/a-technical-seo-guide-to-lighthouse-performance-metrics/292703/
Digging this explainer on Never-Slow Mode by
Alex Russell. The notion of per-interaction budgets/limits is in my opinion something you should probably be thinking about already (regardless of whether it's feature policy that happens or not). https://github.com/slightlyoff/never_slow_mode
Trying to pare down my parts buy list for PhotoFair tomorrow. Who am I kidding, that never works.🤣 https://4photofair.wordpress.com/
I dig the Ergotron LX monitor arms, but could not source a wall mount. Time to cut, weld, and mount my own. https://justinribeiro.com/chronicle/2019/02/15/welding-up-a-custom-ergotron-lx-wall-mount-bracket/
I maintain that examples like this is where WebAssembly shines and is most accessible to devs today; replacement of poor computation perf to smooth perf across browsers/embed VMs. A really well written analysis from Surma. https://developers.google.com/web/updates/2019/02/hotpath-with-wasm
We had a great wide ranging conversation with
@auchenberg about Visual Studio Code, web standards, DevTools, and his latest experimental extension for Code, browser-preview with Chrome headless. Don't miss it! https://thewebplatformpodcast.com/183-visual-studio-code
Working on a show pitch, basically The Great British Bake Off but for web components. You get a mix of devs in a tent focused on WC output (think lit, stencil, et cetera) while @Paul_Kinlan (the show requires a Paul by definition) and @notwaldorf review.
It would be glorious.
lit-html hits 1.0.0 https://github.com/Polymer/lit-html/releases/tag/v1.0.0, as lit-element follows suit: https://github.com/Polymer/lit-element/releases/tag/v2.0.0🎉♥👍
I ♥ the web and say words. The Web Platform podcast. Work on web performance and help companies build on the platform. Ordinary. ☕ powered, 👪 driven.
