I want to explore making frameworks less "framework-y". I'm curious how far you could go in that direction.
I want simpler things and less to worry about.

Yesterday at TPAC I publicized my draft proposal for adding a declarative templating API to the DOM.
github.com/justinfagnan...
The repo has:
📖 Explainers for the templating API and DOM scheduler API
🏗️ Full prototype implementations
⚗️ a JSX transform
⚛️ a mini React-like framework

- Surprise that, until 4.0, it had used XMLHttpRequest instead of fetch.
- Surprise that some features rely on eval().

This is quite a banger feature for web perf engineers. In Chrome Canary, you can now turn on an experimental feature to throttle single requests!

This is golden to check the performance impact of a delayed resource. 👏

Hi @bkardell.com I enjoyed your Blessing of the Strings article but had a question. I've set a Content-Security-Policy: require-trusted-types-for 'script' header
If I use setHTMLUnsafe() with a string, it will cause a TypeError. The whole reason to use setHTMLUnsafe is to set unsafe HTML.

With Firefox enabling sanitizer API in nightly, I'm pretty excited to see if frameworks will pick this feature up sooner rather than later and offer an alternative to "dangerouslySetInnerHtml". I can see a setHTML and setHTMLUnsafe directive pair letting users pass in options to those functions.

If you’ve been using third-party UI libraries to build your websites, then you might be pleasantly surprised by what’s possible with plain ol’ #HTML these days. While those libraries can be useful for some projects and scenarios, they’re probably a lot less necessary than you might think. #webdev
