That was really cool! One small question: is the ".mjs" extension a typo? I thought that was Node-only and wouldnt work in the browser.
Not sure. Anyone can tell if it matters in browser? cc @rauschma
For modules, filename extensions don’t matter, but they must be served with JS MIME types: https://mimesniff.spec.whatwg.org/#javascript-mime-type …
Thanks. So you mean the response MIME of server right?
From my article on dynamic import(): https://developers.google.com/web/updates/2017/11/dynamic-import … Although browsers support other MIME types, only `text/javascript` should be used for JavaScript: https://html.spec.whatwg.org/multipage/scripting.html#scriptingLanguages …pic.twitter.com/9mrCYDVd0n
But isn’t text/javascript obsolete? I’ve always thought application/javascript is the most correct MIME type for JavaScript.
That’s not the case. See the links in my previous tweet for the explanation.
Hmm
If you google, everyone says that application/javascript is the correct one. See also: https://tools.ietf.org/html/rfc4329#section-8 …
