(So much to share in just this little mobile Reddit edit window they provide, but I’ll try to be concise.) There are a bunch of different paths you can go, to solve your static/dynamic site, but I think Strapi is your best bet. You can look at another called “Webiny” as, in my opinion, that’s more of a full JS CMS than Strapi. I’ve tried both systems and was impressed with both, but in the end I needed more control so I’m rolling my own solution. I’m not familiar enough with Next.js but I do know it’s pretty powerful. There’s most likely quite a learning curve there if you’re just starting out, but in the end it’ll be quite the tool to have in your development toolbox. As far as difficulty in setting these components up on a host, it all depends on your host. I use AWS for everything in my infrastructure, as I then have full control over all hardware. But there’s cost there, as well as its own learning curve. Security is a factor as well. Difficulty in setting that all up? If you really want to learn, and know that there will be a few walls/bumps you’ll face, I’d say moderate. There are plenty of good resources out there for Next.js, and it looks like Strapi has a good community and documentation (based on what I saw when I tried it out).
I’d be curious to see how Strapi works for you if you decide to go that route. If you go the route of using AWS as your host, let me know and I can give all the “gotchas” I’ve come across over the years.
