  , but if we use the same component again to draw attention to content in a sidebar, it should be an . Often, we just kind of lazily dodge this whole issue by making it a and saying “good enough”…but, it’s not really good enough. Thankfully, we have other options! One used by several UI component libraries is something known as the “as” prop pattern, which allows you to pass the semantic tag into a custom component and then render the wrapper as that. import React from 'react'; export default function Callout(props) { const { as: Element, children } = props; return {children}Element> } Callout.defaultProps = { as: 'p', }; Enter fullscreen mode Exit fullscreen mode This works by destructuring the props, which then allows us to alias that ‘props.as’ value as “Element” and pass it right into the component tag itself. We’ve also included a defaultProps safety net, here, so that the element will always be rendered with something as the tag. That means that when we use this component, it will look like this in our JSX: TestCallout> Enter fullscreen mode Exit fullscreen mode …and then like this in the browser, when we inspect the element: All things considered, it’s an easy thing to add to our components, and it makes a hell of a difference for preserving the semantic structure! Don’t Forget Your Children! Another challenge that comes with writing reusable components has to do with the accessibility information attached to the children inside those components. Things like icons, labels, alt text, and more are all all variable content that can be easily overlooked when a component is being reused in different situations and contexts. You always want to make sure that you’re including unique and descriptive content for these elements, even if that makes the generalization of a given component slightly harder. So, for example, let’s say you’re creating a product card component that’s going to include a photo of the product, a name, a price, and a “Purchase” button. That product photo is going to different for every single one of those cards, so you need to make sure that you’ve accounted for variable alt text and you’re not just repeating “Product photo” as the alt text for every single card. Use Fragments One more thing we can do to make our apps as accessible as possible is to make use of fragments. Because fragments weren’t fully supported until React 16.2 (in 2017), some folks who established their coding habits in React before that point can kinda forget to make use of them. Which is a shame, because fragments are incredibly helpful for preserving that DOM structure! Basically, when we want to add multiple elements to a React component, they need to have some kind of wrapper. As we know, this: return (

  Hello Worldh1>

  Nice to meet you!p> ); Enter fullscreen mode Exit fullscreen mode …is just going to end in an error. They need to be inside some kind of container element, and (pre-fragments) that was usually a . We can see the obvious downside of this: lots (and lots, and lots) of effectively meaningless and unnecessary divs cluttering up the DOM because we needed them in order to make React play nice. This is disruptive from an accessibility standpoint in a couple different ways: Assistive technologies make use of landmark elements to understand the structure of the page – tags like main, nav, section, article, footer, and more. By using those elements at the highest levels, we allow them to understand the structure of the page and what’s in it. When this is cluttered with divs…it’s less useful. When HTML is expecting a specific order or structure with nested elements, throwing random in there creates invalid HTML. That includes things like s that expect s or s, or s that expect s. Our browsers are usually adaptive enough to still render something, even when there’s a weird div in the middle breaking things…but (once again) this really throws a wrench in the works for screen readers and other assistive technologies. Thankfully, fragments allow us to create empty wrappers that will satisfy the needs of the JSX, and then not actually render anything in the HTML. So we can write code like this: return ( <>

  Hello Worldh1>

  Nice to meet you!p> > ); …to solve the problem and get the best of both worlds. Use an Accessibility Linter Especially if you’re just starting out with accessibility, it can be extremely helpful to have something to help check your code and remind you of guidelines that you might have forgotten about while you were working. For React and JSX, I recommend the eslint-plugin-jsx-a11y – a plugin that will review your JSX for common accessibility issues. It will throw errors when you’ve neglected to write alt text or include captions for media, assesses the autocomplete validity of your forms, checks for associated labels, and so much more! Keep in mind, this is only checking your static code in the editor – not the actual, rendered DOM – so it’s not a replacement for proper accessibility testing in the browser. However, it’s still an immensely helpful tool that you can use to catch things early and help build the habit of coding accessibly. Handling Component Re-Renders Beyond the JSX, though, there are other things to consider – we also have to keep in mind the how a component re-render will impact the accessibility of our application. One of the ways this can be most disruptive is by throwing off the focus state. The focus is how a browser shows which item is currently highlighted, when a user is navigating via keyboard or assistive technology. You’ve probably used it before to quickly navigate between form fields or options in a dropdown without reaching for your mouse…but you can (and should!) try it yourself – just hit tab after you load a page, and you should see the focus appear on the first selectable element. By repeatedly pressing tab, the user can cycle through interactive elements on the page without needing to point and click. The focus order is the order in which those elements are highlighted, and that default focus order is determined by (you guessed it) – the order of elements in the DOM. The React Component Lifecycle I’m going to assume you’re all at least vaguely familiar with the React component lifecycle, so I won’t spend much time here beyond just pointing out that the DOM gets updated not only when the application first loads, but then again each time a component re-renders – which, as we know, is primarily when new props are passed or state is updated, unless we’re manually forcing a re-render. *Image from https://projects.wojtekmaj.pl/react-lifecycle-methods-diagram/ * When you’re focusing on an element in a component that gets re-rendered, that focus is often either just lost or it gets bumped to another element – both of which are disorienting and frustrating for a user. That means that it’s our job as the developer to make sure we’ve got a plan in place for re-focusing when we know we’re going to trigger a component re-render that changes the structure of the DOM – things like confirmation or error text that appears, secondary or conditional form questions, pop-up modals that get triggered, etc. ⚠️ Before we dig into some technical approaches for manually managing focus, I want to start by saying that the focus is not something you should touch, unless you absolutely have to. Overriding the natural focus order should only be done to accommodate or fix disruptions we have made to the DOM. Generally, you really don’t want to mess with the focus order – the default order is going to be the most intuitive, so unless we’ve done something to mess that up, we don’t wanna put our hands in it. These approaches should ONLY be used in order to fix what we have broken by messing with the DOM. With great power comes great responsibility, and this is a tool to be used cautiously. That said, there are a couple ways to do this, depending on what you’re trying to accomplish. The simplest way is to use the autoFocus prop. AutoFocus autoFocus will automatically shift the focus to the element it’s applied to, overriding the default focus order. Let’s take a look at an example.

  Username label> Password label> form> I’ve placed the autoFocus prop here on the Password input box, and even when we refresh the page, the focus jumps over everything else on the page and focuses in the Password box. We can see how this might be harmful when misused – if this was a full page and I were to remove autoFocus, the focus will naturally start somewhere much more logical – probably the navigation. This is not a real-world situation where I would override the focus, I’m only doing it here to demonstrate the approach because the situations in which you would want something like this tend to be more complex. This is primarily useful to us when we’re using it in conditionally rendered components. One of the most common use cases here is a form question that triggers a followup question if the user selects “Yes”. If the user selects “No”, there’s no second question that appears. In that case, it makes total sense that we’d want the focus to automatically shift to that new input box as soon as it renders after the user has made the yes/no selection in the previous question. Refs & UseEffect() Another way to accomplish the same goal with a more hands-on approach is using refs and hooking into the lifecycle of the component with useEffect. In this case, we manually set the element we want to redirect the focus to by creating a ref and adding it to the element, then calling focus() on that ref with the useEffect hook. In this code sample, I’m just recreating what we did with autoFocus – forcing the focus to override the natural order and jump to the second input box – but using this method, instead. Here, I’ve got the same super simple fake login component with those two input boxes. I’ve set up my ref – passwordinput – with useRef() and added it to the password input box in the JSX. By using the useEffect() hook, we’re telling React to do this thing immediately after component render – and in our case “this thing” is setting the element tagged with that passwordinput ref to be the current focus target. export default function Login(props) { const pwinput = useRef(null); useEffect(() => { pwinput.current.focus(); }) return ( Username label>
  Password label> form> ) } If you prefer classes instead of functional components, you can accomplish the same thing by using componentDidMount(). This approach is most useful when (for whatever reason) there’s a different action that you want to trigger the focus change that’s not the component render – for example, closing a modal and re-focusing where the user left off. With this approach, you can call that same focus() function wherever you need it. It just give you a little more control than the autoFocus approach. Single Page Applications & Page Titles Finally, let’s talk about page titles. The page title is the first element that gets announced by a screen reader, when a user loads your page. They’re important for giving your user a gist of what’s on the page so they know what to expect, orienting them within the larger structure of your application, helping them tell tabs apart, and helping them set useful bookmarks. Ideally, your page title will include a short description of the page content, as well as your application or brand name. Image from https://www.mainstreetroi.com/where-are-the-webpage-titles-descriptions-and-headers/ The issue, of course, is that the page title doesn’t automatically update as a user navigates through your React app because it’s a single page application. So…we’re not actually changing any pages, and therefore not triggering page title updates. Obviously, from an accessibility standpoint, this is not ideal. The easiest way to fix this, in my opinion, is to use a library called [react-helmet](https://github.com/nfl/react-helmet), which helps manage changes to the document head. It is, seriously, one of the most dead-easy libraries I have ever used in my life. You just add it to your app, import it, and then anywhere in the component that you’re calling from your router, you can write: My Page Titletitle>Helmet> You can put them anywhere in the component and it will work, but I like to keep them at the top – I think it makes the most organizational sense. Literally…it’s just that easy. Really nice, genuinely quick accessibility win! More Resources These are just a few of the most helpful things that you can do, to get some quick accessibility wins in the books when you’re first starting out with accessibility in React – this is not intended to be a full and complete guide to making your app accessible. If you’re looking to dive a little deeper (and I hope you are!), then I highly recommend these resources: A Guide to Keyboard Accessibility: JavaScript (blog) React and Accessibility Fundamentals (video) React Docs: Accessibility (documentation) Accessibility in React (documentation) Avoid Analysis Paralysis I’ve found accessible development to be one of the the places where it’s easiest to fall into analysis paralysis – there’s always something that you feel like you need to do more research on first, something that you heard someone else is doing, or just a vague feeling that you don’t really know enough yet to start tackling accessible coding, yourself. Just one more blog, one more conference talk, one more video, and then you’ll be ready to start writing accessible code. Meanwhile, our applications – and more importantly, our users – are stuck with the same old inaccessible code that we just keep writing. In my opinion, the best thing we can do is to start writing accessible code to the best of our ability*,* with the acknowledgement that we might make a mistake! Accessibility isn’t an on/off switch, it’s a sliding scale. We code accessible features as we’re able, based on what we know right now and the current accessibility-related guidance. It might not be perfect 100% of the time, but anything is better than ignoring accessibility entirely. And hey – code isn’t carved into stone, right? You can always go back and refactor something once you’ve learned how to do it better. It can be easy to build up the idea of coding accessibly in our heads into something so large and intimidating that we can always find an excuse for putting it off. But in reality, as I hope that I’ve demonstrated here, accessible code is just a series of small to moderate adjustments to your development and testing process that are all absolutely do-able by developers of all experience levels. After all, learning new stuff is just part of our job. Frameworks, libraries, best practices, even languages themselves change and evolve over time – once you start thinking of accessibility the same way and recognize that it’s not an optional upgrade, you can start to build accessible development into your existing processes and patterns at work!
