Web development has two flavors of graceful degradation
Offline-first is great for web apps
He mentions, briefly:
But it seems to me this conflates two very different use-cases that we should consider separately:
- A single page web app (an "app" from here on)
- A website that consists of multiple pages (a "site" from here on)
Not everything on the web is an app
The generational disconnect I mentioned earlier seems to be coming from the fact that web developers are in two groups, with different "default" ways of thinking about web development. The first group, who turned up in the past 5 or maybe even 10 years, think of it as application development with the web as a medium. The second group, which includes myself, who started 20 years ago think of it as building a set of discrete pages. Obviously, both groups can and do build both types.
Progressive rendering isn't very useful for apps
Progressive rendering is essential for sites
Long live web development, in every flavor
As I argue every time I give my Stuff Everybody Knows talk, web development is not a competition between single page web apps and multi-page web sites. Neither is going to "win". There will always be both kinds of web experiences, and what counts as "graceful degradation" is very different depending which one you're building.
Nobody's arguing that graceful degradation is a bad policy, merely what it looks like, and I think these widely diverged use-cases is the source of the disagreement. In fact, as I mentioned on Twitter early this month, web app development and web site development are so different now that they probably shouldn't be called the same thing anymore. Both types of developers are web developers, but you should probably specify which flavor you're talking about. Web app development and web site development (pick your own terminology if you don't like mine, just make it unambiguous) are so different now that rules from one flavor almost never apply to the other.
