The frameworks that are popular at the moment make it harder.

I put together a simple set of frameworks, engines and libraries that let me build real-time SPAs really quickly and easily. I've built a complex production app with it in a couple of weeks and it works really well. I tried to promote it a while ago and those who tried it seemed to really like it but it never became popular.

Promoting technical solutions these days is literally impossible if you're not a rock star developer.

I don't even care about promoting it anymore. It's my own secret toolkit now.

If people want to believe that SPAs are harder to build, that's fine. But I'm going to keep building them because for me with my tooling of choice it's much much easier.
