Personally, I've yet to see a real solid case for SPAs. I know that may be confused for negativity towards the SPA technology, but I always found it to be a technology looking for a problem. Again, in my experience, SPAs break the web 99% of the time. The times that they don't (e.g. Gmail), I still don't see what an SPA brings to the table that a simple MPA didn't. Yeah Gmail is nice, but it's no where near as good as a decent desktop or mobile mail app. And its miles away from a good, well structured MPA. SPAs just seem to sit in this no-mans land for me, and I'm not sure that more technology is the answer. It's like Flash. When Flash came out I used to be a Flash developer for a while. But I had an epiphany as to why Flash development was so hard. It was the entire concept of the timeline, something that is at the core of Flash. A timeline is a sequence of keyed steps over time. The problem with this is that it make interactivity next to impossible; you were constantly fighting against the core purpose of Flash (play items in sequence over time). How do you handle users interrupting this sequence with their constant demands for interactivity? The answer was to throw the entire timeline concept out the window and generate all objects, items and stuff using code. That way you could handle arbritary interactions from the user. Well, I'm sure you can imagine how ridiculous that got over time. Frameworks and libraries and hacks and workarounds and generally just a big fat mess because Flash devs were constantly trying use Flash for something it was never designed to do in the first place. For me, personally, SPAs and the related technology bear some of the similar hallmarks. Some developers want to use Web Browsers to write the equivalent of desktop apps. But browsers and the web in particular do not have the same interaction patterns as desktop apps (or mobile). But that is absolutely fine! The web is something else, it is its own thing. But thats just me. By all means go for it! You are right that progress in technology is a good thing. I'm just wary of misdirected technological gains, like smart-jars, digital credit cards and smart smoke alarms that require internet connections. To sum up; I wouldn't say it's negativity, it's more that some people are just not convinced by the concept at its core.
