My post was not about what is probable but what is possible. Hey is an app, not a website, that has been built by an entire team of developers over 2+ years, with multiple millions of dollars, not a gatsby app on Netlify made in 30 minutes. They could have made this work fully offline in React in this time, if they wanted to.

Off-line support is trivial. https://twitter.com/javan/status/1274168003773566977

Ummm, anyone claiming offline support is trivial has clearly never written offline support. I'll give you a clue: cache invalidation (and data reconciliation) is hard.

In your post you made it sound like most SPA frameworks will take care of this for you.

> With a SPA framework, it could add it to the local list of emails and push to the server in the background, so it would transition instantly regardless of connectivity. It would also work offline.

None of this happens automatically with SPA frameworks, and it requires a custom implementation of offline functionality in the context of the business domain (what to store, what to send to the server when connection is reestablished, which data to re-synchronize). It's hard to do, which I think is why most SPAs don't do it.

Moreover, it's clear that DHH is not interested in even something like basic PWA support, and will instead spend his time attacking Apple for not approving their app on the app store.

Let me paint a somewhat less strawman-y picture of DHH for the benefit of those who doesn't know him:

- He is the guy who built Rails and inspired a huge number of other frameworks from Symfony and Laravel to parts of modern JavaEE.

- "His" apps (obviously built together with others) were early examples of actually working Ajax.

- He has been preaching against the hunt for unicorns for a decade or so I think, talking about sanity and sustainability.

- I think the thing about PWA is less that he isn't interested in it and more that he wants things to just work across all browsers.

- The thing about Apple is less about attacking Apple and more about defending himself - and in the process a number of smaller devs - against abuse from Apple.

I have a lot of nice things to say about Apple, but for cases like this where you wonder if it was Apple or Oracle who called you to extort money then Apple deserves all the criticism rhey get (and then some more if you ask me). Just because one is mostly nice doesn't make it OK to run an extortion racket on the side.

(Apples platform, Apples riles one might say but as far as I have seen so far they didn't break any of the rules, so even by that rule Apple is in the wrong here until they change their rules to add something tvat allows them to do this.)
