React (and specifically Next.js) is the new IBM[0]: You’ll never get fired for picking it, but it’s going to be expensive, bloated, difficult to get right, and it’s going to be joyless implementing it every step of the way.
Can't tell about Next.js but my conclusions on React are strictly opposite to yours, as someone with 8 years of exp with React, 15 years of exp in the industry, doing front, back and infra on a daily basis. A former teammate also told me last month that his new shop just rewrote their entire front codebase from Elm to React, because of how simple and fast it is to implement anything with React, and how easy it is to find good developers and well maintained packages for it.
“If it ain't broke, don't fix it.”
“If it ain't broke, don't fix it.”
But it wasn't until lately that the value proposition started making sense to me, because it's just so mature and popular now.
I still haven't seen a newer framework that offers anything beyond a slightly more optimal, or just as often simply different developer UX.
