Por fin me he quitado de encima un potencial problema que me traía de cabeza. El tema de una aplicación crítica ahora se visualiza decentemente y es operativo en el #Webview que usa Microsoft en sus aplicaciones.

La solución es algo enrevesada: incluye un pipeline complejo con #gulp y #webpack usando #SASS, #PostCSS, transpilación de módulos JavaScript, un par de #polyfills, un #ponyfill, una pizca de magia arcana y varios artificios quirúrgicos. Dista de ser perfecta pero por lo menos es funcional.

A Polyfill for the HTML “switch” Element, by @tomayac:

#html #forms #polyfills

This is mostly a question into the void, because I don't know how that's done in the real world.
When people are talking about #polyfills, in the context of #webdev, one argument that always pops up, is that they increase bundle size.
My thought: isn't it possible to dynamically load #javascript when a missing feature is detected in a browser? Does this incur a latency penalty that makes this unfeasible? Or is this actually a valid option?

Still have to rely on webextension-polyfill, but, hopefully, it's not long until #Chrome will expose Extension APIs under browser.* namespace, just like #Firefox.

Y'all remember #PolyfillIO?

I realize the lesson there is; don't depend on code from domains you don't control, and in an ideal world that's what you should do

But is there still a need there? Are there #webPlatform features you'd like to use but you don't want to introduce a build process just to bundle the #polyfill from #NPM?

Or is there no point in #polyfills since #browsers don't share caches between origins these days so there's no precaching benefit anymore?

🌗 加速JavaScript生態系統-失控的Polyfills
➤ 為什麼node_modules文件夾如此龐大？
✤ https://marvinh.dev/blog/speeding-up-javascript-ecosystem-part-6/
許多流行的npm包依賴於比它們需要的多6-8倍的包，其中大部分是不必要的polyfills，這是node_modules文件夾如此龐大的主要原因之一。 eslint生態系統似乎受到影響最大。本文探討了這個問題的起源，並提供了一些解決方案。
+ 這是一個非常有用的文章，讓我更好地瞭解了npm包和polyfills之間的關係。
+ 我從未想過polyfills可能會導致這麼多的依賴問題。這篇文章提供了一些很好的解決方案。
