You had me at “beautifully resilient apps with progressive enhancement”.
This is a great clear walkthrough of enhancing a form submission. A lot of this seems like first principles to me, but if you’ve only ever built single page apps, then thinking about a server-submission process first might well be revelatory.
I can see how this would be good to have fixed at the browser level.
Hui-Jing talks through her process of building a to-do app on Glitch using a progressive enhancement mindset:
I found that HTML out-of-the-box takes care of a lot of things when it comes to collecting user inputs from the front-end, which resulted in much less code required. This is not to say client-side Javascript is bad, because the experience was smoother (and faster) when I used it for updating content.
