  • Project mention: A brief history of web development. And why your framework doesn't matter | | 2024-04-29

    > It’s important to be aware of what you are getting if you go with React, and what you are getting is a far cry from what a framework would offer, with all the corresponding pros and cons.

    Would you like to elaborate on that?

    In my experience, with something as great, size/ecosystem-wise as React, there will almost always be at least one "mainstream" package for whatever you might want to do with it, that integrates pretty well. Where a lot of things might come out of the box with a framework, with a library I often find myself just needing to install the "right" package, and from there it's pretty much the same.

    For example, using or installing and using

    Or something like out of the box, vs installing and using

    Or perhaps vs

    Even adding something that's not there out of the box is pretty much the same, like or

    React will typically have more fragmentation and therefore also choice, but I don't see those two experiences as that different. Updates and version management/supply chain will inevitably be more of a mess with the library, admittedly.

    Now, projects like Next exist and add what some might regard as the missing pieces and work well if you want something opinionated and with lots of features out of the box, but a lot of those features (like SSR) are actually pretty advanced and not always even necessary.
