Frameworks like React are often perceived as accelerators, or even as the only sensible way to do web development. There’s this notion that a more “modern” stack (read: JS-heavy, where the JS ends up running on the user’s browser) allows you to be more agile, release more often with fewer bugs, make code more maintainable, and ultimately launch better sites. In short, the claim is that this approach will offer huge improvements to developer experience, and that these DevEx benefits will trickle down to the user.
But over the years, this narrative has proven to be unrealistic, at best. In reality, for any decently sized JS-heavy project, you should expect that what you build will be slower than advertised, it will keep getting slower over time while it sees ongoing work, and it will take more effort to develop and especially to maintain than what you were led to believe, with as many bugs as any other approach.
Where it comes to performance, the important thing to note is that a JS-heavy approach (and particularly one based on React & friends) will most likely not be a good starting point; in fact, it will probably prove to be a performance minefield that you will need to keep revisiting, risking a detonation with every new commit.
I really like the thinking that goes into this approach. It seems so counter-intuitive at first, but there’s no arguing with the snappy resilient results.
Turns out, if you have a website and you think of the browser as a way to navigate documents — rather than a runtime to execute arbitrary code and fetch, compile, and present them — things can be a lot simpler than our tools often prime us to make them.
A stack is also technical debt, non-transferable knowledge, accelerated obsolescence, and vendor lock-in. That means fragility and overall unnecessary complication. Popular stacks inevitably turn into cargo cults that build in spite of the web, not for it.
The web platform does not require build toolchains. Always default to, and regress to, the fundamentals of CSS, HTML, and JavaScript. Those core standards are the web stack.
This is an excellent one-stop shop of interface patterns:
This is an organic collection of common JS patterns that can be replaced with just HTML, CSS, and no, or very low, JS. As HTML and CSS continue to mature, this collection should expand.
