Why use React?

This isn’t a rhetorical question. I genuinely want to know why developers choose to build websites using React.

There are many possible reasons. Alas, none of them relate directly to user experience, other than a trickle-down justification: happy productive developers will make better websites. Citation needed.

It’s also worth mentioning that some people don’t choose to use React, but its use is mandated by their workplace (like some other more recent technologies I could mention). By my definition, this makes React enterprise software in this situation. My definition of enterprise software is any software that you use but that you yourself didn’t choose.

Inertia

By far the most common reason for choosing React today is inertia. If it’s what you’re comfortable with, you’d need a really compelling reason not to use it. That’s generally the reason behind usage mandates too. If we “standardise” on React, then it’ll make hiring more straightforward (though the reality isn’t quite so simple, as the React ecosystem has mutated and bifurcated over time).

And you know what? Inertia is a perfectly valid reason to choose a technology. If time is of the essence, and you know it’s going to take you time to learn a new technology, it makes sense to stick with what you know, even if it’s out of date. This isn’t just true of React, it’s true of any tech stack.

This would all be absolutely fine if React weren’t a framework that gets executed in browsers. Any client-side framework is a tax on the end user. They have to download, parse, and execute the framework in order for you to benefit.

But maybe React doesn’t need to run in the browser at all. That’s the promise of server-side rendering.

The front end

There used to be a fairly clear distinction between front-end development and back-end development. The front end consisted of HTML, CSS, and client-side JavaScript. The back end was anything you wanted as long as it could spit out those bits of the front end: PHP, Ruby, Python, or even just a plain web server with static files.

Then it became possible to write JavaScript on the back end. Great! Now you didn’t need to context-switch when you were scripting for the client or the server. But this blessing also turned out to be a bit of a curse.

When you’re writing code for the back end, some things matter more than others. File size, for example, isn’t really a concern. Your code can get really long and it probably won’t slow down the execution. And if it does, you can always buy your way out of the problem by getting a more powerful server.

On the front end, your code should have different priorities. File size matters, especially with JavaScript. The code won’t be executed on your server. It’s executed on all sorts of devices on all sorts of networks running all sorts of browsers. If things get slow, you can’t buy your way out of the problem because you can’t buy every single one of your users a new device and a new network plan.

Now that JavaScript can run on the server as well as the client, it’s tempting to just treat the code the same. It’s the same language after all. But the context really matters. Some JavaScript that’s perfectly fine to run on the server can be a resource hog on the client.

And this is where it gets interesting with React. Because most of the things people like about React still apply on the back end.

React developers

When React first appeared, it was touted as front-end tool. State management and a near-magical virtual DOM were the main selling points.

Over time, that’s changed. The claimed speed benefits of the virtual DOM turned out to be just plain false. That just left state management.

But by that time, the selling points had changed. The component-based architecture turned out to be really popular. Developers liked JSX. A lot. Once you got used to it, it was a neat way to encapsulate little bits of functionality into building blocks that can be combined in all sorts of ways.

For the longest time, I didn’t realise this had happened. I was still thinking of React as being a framework like jQuery. But React is a framework like Rails or Django. As a developer, it’s where you do all your work. Heck, it’s pretty much your identity.

But whereas Rails or Django run on the back end, React runs on the front end …except when it doesn’t.

JavaScript can run on the server, which means React can run on the server. It’s entirely possible to have your React cake and eat it. You can write all of your code in React without serving up a single line of React to your users.

That’s true in theory. The devil is in the tooling.

Priorities

Next.js allows you to write in React and do server-side rendering. But it really, really wants to output React to the client as well.

By default, you get the dreaded hydration pattern—do all the computing on the server in JavaScript (yay!), serve up HTML straight away (yay! yay!) …and then serve up all the same JavaScript that’s on the server anyway (ya—wait, what?).

It’s possible to get Next.js to skip that last step, but it’s not easy. You’ll be battling it every step of the way.

Astro takes a very different approach. It will do everything it can to keep the client-side JavaScript to a minimum. Developers get to keep their beloved JSX authoring environment without penalising users.

Alas, the collective inertia of the “modern” development community is bound up in the React/Next/Vercel ecosystem. That’s a shame, because Astro shows us that it doesn’t have to be this way.

Switching away from using React on the front end doesn’t mean you have to switch away from using React on the back end.

Why use React?

The titular question I asked is too broad and naïve. There are plenty of reasons to use React, just as there are plenty of reasons to use Wordpress, Eleventy, or any other technology that works on the back end. If it’s what you like or what you’re comfortable with, that’s reason enough.

All I really care about is the front end. I’m not going to pass judgment on anyone’s choice of server-side framework, as long as it doesn’t impact what you can do in the client. Like Harry says:

…if you’re going to use one, I shouldn’t be able to smell it.

Here’s the question I should be asking:

Why use React in the browser?

Because if the reason you’re using React is cultural—the whole team works in JSX, it makes hiring easier—then there’s probably no need to make your users download React.

If you’re making a single-page app, then …well, the first thing you should do is ask yourself if it really needs to be a single-page app. They should be the exception, not the default. But if you’re determined to make a single-page app, then I can see why state management becomes very important.

In that situation, try shipping Preact instead of React. As a developer, you’ll almost certainly notice no difference, but your users will appreciate the refreshing lack of bloat.

Mostly though, I’d encourage you to investigate what you can do with vanilla JavaScript in the browser. I totally get why you’d want to hold on to React as an authoring environment, but don’t let your framework limit what you can do on the front end. If you use React on the client, you’re not doing your users any favours.

You can continue to write in React. You can continue to use JSX. You can continue to hire React developers. But keep it on your machine. For your users, make the most of what web browsers can do.

Once you keep React on the server, then a whole world of possibilities opens up on the client. Web browsers have become incredibly powerful in what they offer you. Don’t let React-on-the-client hold you back.

And if you want to know more about what web browsers are capable of today, come to Web Day Out in Brighton on Thursday, 12th March 2026.

Decision time

I’ve always associated good design with thoughtfulness. Like, I should be able to point to any element in an interface and the designer should be able to tell me the reasons it’s there. Those reasons may be rooted in user needs or asthetics or some other consideration, but the point is that there’s a justification for it. Justify every pixel!

But I’ve come to realise that this is a bit reductionist. Now when I point at an interface element, I still expect the designer to be able to justify its inclusion, but I’d also like to know the trade-offs that were made.

Suppose there’s a large hero image. I’m sure the designer would have no problem justifying its inclusion on the basis of impact and the emotional heft it delivers. But did they also understand the potential downsides? Were they aware of the performance implications of including a large image?

I hope the answer to both questions is yes. They understood the costs, but they decided that, on balance, the positives outweighed the negatives.

When it comes to the positives, universal principles of design often apply. Colour theory, typography, proximity, and so on. But the downsides tend to be specific to the medium that the design is delivered in.

Let’s say you’re designing for print. You want to include an extra typeface just for footnotes. No problem. There isn’t really a downside. In print, you can use all the typefaces you want. But if this were for the web, then the calculation would be different. Every extra typeface comes with a performance penalty. A decision that might be justified in one medium might not work in another medium.

It works both ways; on the web you can use all the colours you want, without incurring any penalties, but in print—depending on the process you’re using—you might have to weigh up that decision very differently.

From this perspective, every design decision is like a balance sheet. A good web designer understands the benefits and the costs behind each decision they make.

It’s a similar story when it comes to web development. Heck, we even have the term “tech debt” to describe decisions that we know aren’t for the best in the long term.

In fact, I’d say that consideration of the long-term effects is something that should play a bigger part in technical decisions.

When we’re weighing up the pros and cons of using a particular tool, we have a tendency to think in the here and now. How might this help me right now? How might this hinder me right now?

But often a decision that delivers short-term gain may well end up delivering long-term pain.

Alexander Petros describes this succinctly:

Reopen a node repository after 3 months and you’ll find that your project is mired in a flurry of security warnings, backwards-incompatible library “upgrades,” and a frontend framework whose cultural peak was the exact moment you started the project and is now widely considered tech debt.

When I wrote about making the Patterns Day website I described my process as doing it “the long hard stupid way”—a term that Frank coined in a talk he gave a few years back. But perhaps my hands-on approach is only long, hard and stupid in the short time. With each passing year, the codebase will retain a degree of readability and accessibility that I would’ve sacrificed had I depended on automated build processes.

Robin Berjon puts this into the historical perspective of Taylorism and Luddism:

Whenever something is automated, you lose some control over it. Sometimes that loss of control improves your life because exerting control is work, and sometimes it worsens your life because it reduces your autonomy.

Or as Marshall McLuhan put it:

Every extension is also an amputation.

…which is fine as long as the benefits of the extension outweigh the costs of the amputation. My worry is that, when it comes to evaluating technology for building on the web, we aren’t considering the longer-term costs.

Maintenance matters. With the passing of time, maintenance matters more and more.

Maybe we avoid thinking about the long-term costs because it would lead to decision paralysis. That’s understandable. But I take comfort from some words of wisdom on the web from the 1990s. Tim Berners-Lee’s style guide for hypertext:

Because hypertext is potentially unconstrained you are a little daunted. Do not be. You can write a document as simply as you like. In many ways, the simpler the better.

Chain of tools

I shared this link in Slack with my co-workers today:

Cultivating depth and stillness in research by Andy Matuschak.

I wasn’t sure whether it belonged in the #research or the #design channel. While it’s ostensibly about research, I think it applies to design more broadly. Heck, it probably applies to most fields. I should have put it in the Slack channel I created called #iiiiinteresting.

The article is all about that feeling of frustration when things aren’t progressing quickly, even when you know intellectually that not everything should always progress quickly.

The article is filled with advice for battling this feeling, including this observation on curiosity:

Curiosity can also totally change my relationship to setbacks. Say I’ve run an experiment, collected the data, done the analysis, and now I’m writing an essay about what I’ve found. Except, halfway through, I notice that one column of the data really doesn’t support the conclusion I’d drawn. Oops. It’s tempting to treat this development as a frustrating impediment—something to be overcome expediently. Of course, that’s exactly the wrong approach, both emotionally and epistemically. Everything becomes much better when I react from curiosity instead: “Oh, wait, wow! Fascinating! What is happening here? What can this teach me? How might this change what I try next?”

But what really resonated with me was this footnote attached to that paragraph:

I notice that I really struggle to generate curiosity about problems in programming. Maybe it’s because I’ve been doing it so long, but I think it’s because my problems are usually with ephemeral ideas, incidental to what I actually care about. When I’m fighting some godforsaken Javascript build system, I don’t feel even slightly curious to “really” understand those parochial machinations. I know they’re just going to be replaced by some new tool next year.

I feel seen.

I know I’m not alone. I know people who were driven out of front-end development because they felt the unspoken ultimatum was to either become a “full stack” developer or see yourself out.

Remember Chris’s excellent post, The Great Divide? Zach referenced it recently. He wrote:

The question I keep asking though: is the divide borne from a healthy specialization of skills or a symptom of unnecessary tooling complexity?

Mostly I feel sad about the talented people we’ve lost because they felt their front-of-the-front-end work wasn’t valued.

But wait! Can I turn my frown upside down? Can I take Andy Matuschak’s advice and say, “Oh, wait, wow! Fascinating! What is happening here? What can this teach me?”

Here’s one way of squinting at the situation…

There’s an opportunity here. If many people—myself included—feel disheartened and ground down by the amount of time they need to spend dealing with toolchains and build systems, what kind of system would allow us to get on with making websites without having to deal with that stuff?

I’m not proposing that we get rid of these complex toolchains, but I am wondering if there’s a way to make it someone else’s job.

I guess this job is DevOps. In theory it’s a specialised field. In practice everyone adding anything to a codebase partakes in continual partial DevOps because they must understand the toolchains and build processes in order to change one line of HTML.

I’m not saying “Don’t Make Me Think” when it comes to the tooling. I totally get that some working knowledge is probably required. But the ratio has gotten out of whack. You need a lot of working knowledge of the toolchains and build processes.

In fact, that’s mostly what companies hire for these days. If you’re well versed in HTML, CSS, and vanilla JavaScript, but you’re not up to speed on pipelines and frameworks, you’re going to have a hard time.

That doesn’t seem right. We should change it.

Lighthouse bookmarklet

I use Firefox. You should too. It’s fast, secure, and more privacy-focused than the leading browser from the big G.

When it comes to web development, the CSS developer tooling in Firefox is second-to-none. But when it comes to JavaScript and network-related debugging (like service workers), Chrome’s tools are currently better than Firefox’s (for now). For example, Chrome has a tab in its developer tools that lets you run Lighthouse on the currently open tab.

Yesterday, I got the Calibre newsletter, which always has handy performance-related links from Karolina. She pointed to a Lighthouse extension for Firefox. “Excellent!”, I thought, and I immediately installed it. But I had some qualms about installing a plug-in from Google into a browser from Mozilla, particularly as the plug-in page says:

This is not a Recommended Extension. Make sure you trust it before installing

Well, I gave it a go. It turns out that all it actually does is redirect to the online version of Lighthouse. “Hang on”, I thought. “This could just be a bookmarklet!”

So I immediately uninstalled the browser extension and made this bookmarklet:

Lighthouse

Drag that up to your desktop browser’s bookmarks toolbar. Press it whenever you’re on a site that you want to test.

Frustration

I had some problems with my bouzouki recently. Now, I know my bouzouki pretty well. I can navigate the strings and frets to make music. But this was a problem with the pickup under the saddle of the bouzouki’s bridge. So it wasn’t so much a musical problem as it was an electronics problem. I know nothing about electronics.

I found it incredibly frustrating. Not only did I have no idea how to fix the problem, but I also had no idea of the scope of the problem. Would it take five minutes or five days? Who knows? Not me.

My solution to a problem like this is to pay someone else to fix it. Even then I have to go through the process of having the problem explained to me by someone who understands and cares about electronics much more than me. I nod my head and try my best to look like I’m taking it all in, even though the truth is I have no particular desire to get to grips with the inner workings of pickups—I just want to make some music.

That feeling of frustration I get from having wiring issues with a musical instrument is the same feeling I get whenever something goes awry with my web server. I know just enough about servers to be dangerous. When something goes wrong, I feel very out of my depth, and again, I have no idea how long it will take the fix the problem: minutes, hours, days, or weeks.

I had a very bad day yesterday. I wanted to make a small change to the Clearleft website—one extra line of CSS. But the build process for the website is quite convoluted (and clever), automatically pulling in components from the site’s pattern library. Something somewhere in the pipeline went wrong—I still haven’t figured out what—and for a while there, the Clearleft website was down, thanks to me. (Luckily for me, Danielle saved the day …again. I’d be lost without her.)

I was feeling pretty down after that stressful day. I felt like an idiot for not knowing or understanding the wiring beneath the site.

But, on the other hand, considering I was only trying to edit a little bit of CSS, maybe the problem didn’t lie entirely with me.

There’s a principle underlying the architecture of the World Wide Web called The Rule of Least Power. It somewhat counterintuitively states that you should:

choose the least powerful language suitable for a given purpose.

Perhaps, given the relative simplicity of the task I was trying to accomplish, the plumbing was over-engineered. That complexity wouldn’t matter if I could circumvent it, but without the build process, there’s no way to change the markup, CSS, or JavaScript for the site.

Still, most of the time, the build process isn’t a hindrance, it’s a help: concatenation, minification, linting and all that good stuff. Most of my frustration when something in the wiring goes wrong is because of how it makes me feel …just like with the pickup in my bouzouki, or the server powering my website. It’s not just that I find this stuff hard, but that I also feel like it’s stuff I’m supposed to know, rather than stuff I want to know.

On that note…

Last week, Paul wrote about getting to grips with JavaScript. On the very same day, Brad wrote about his struggle to learn React.

I think it’s really, really, really great when people share their frustrations and struggles like this. It’s very reassuring for anyone else out there who’s feeling similarly frustrated who’s worried that the problem lies with them. Also, this kind of confessional feedback is absolute gold dust for anyone looking to write explanations or documentation for JavaScript or React while battling the curse of knowledge. As Paul says:

The challenge now is to remember the pain and anguish I endured, and bare that in mind when helping others find their own path through the knotted weeds of JavaScript.

PPK writes of modern web development:

Tools don’t solve problems any more, they have become the problem.

I think he’s mostly correct, but I think there is some clarification required.

Web development tools fall into two broad categories:

  1. Local tools like preprocessors, task managers, and version control systems that help the developer output their own HTML, CSS, and JavaScript.
  2. Tools written in HTML, CSS, and JavaScript that the end user has to download for the developer to gain benefit.

It’s that second category that contain a tax on the end user. Stop solving problems you don’t yet have.
