Unfortunately, out of the box Context comes with a limiting and not very convenient API. In most cases, I choose to wrap both the provider and consumer with a custom component and a hook. Some of the issues I highlight are more relevant to library maintainers, but most apply to app development as well.</p><p>In this post, we revisit an <code>AdaptivityContext</code> that allows components to read viewport dimension data — pixel <code>width</code> and breakpoint status, <code>isMobile</code>:</p><pre class="language-jsx"><code class="language-jsx"><span class="token keyword">const</span> <span class="token function-variable function">getWidth</span> <span class="token operator">=</span> <span class="token punctuation">(</span><span class="token punctuation">)</span> <span class="token operator">=></span> window<span class="token punctuation">.</span>innerWidth<span class="token punctuation">;</span><br><span class="token keyword">const</span> <span class="token function-variable function">isMobile</span> <span class="token operator">=</span> <span class="token punctuation">(</span><span class="token parameter"><span class="token literal-property property">w</span><span class="token operator">:</span> number</span><span class="token punctuation">)</span> <span class="token operator">=></span> w <span class="token operator"><</span> <span class="token number">600</span><span class="token punctuation">;</span><br><span class="token keyword">const</span> AdaptivityContext <span class="token operator">=</span> <span class="token function">createContext</span><span class="token punctuation">(</span><span class="token punctuation">{</span><br> <span class="token literal-property property">w</span><span class="token operator">:</span> <span class="token function">getWidth</span><span class="token punctuation">(</span><span class="token punctuation">)</span><span class="token punctuation">,</span><br> <span class="token literal-property property">isMobile</span><span class="token operator">:</span> <span class="token function">isMobile</span><span class="token punctuation">(</span>getWidth<span class="token punctuation">)</span><span class="token punctuation">,</span><br><span class="token punctuation">}</span><span class="token punctuation">)</span><span class="token punctuation">;</span></code></pre><p>If you've read my <a href="/2021/10/04/react-context-dangers/">post on Context performance issues,</a> you know it is not the best design choice — components that only care about <code>isMobile</code> will still re-render on every <code>width</code> change. Still, suppose that's what we happen to have on our project. How can custom <code>AdaptivityProvider</code> and <code>useAdaptivity</code> help us?</p><p><img src="/images/wrapped-context.jpg" alt=""></p><h2>Wrap useContext</h2><p>In raw context API, the consuming components utilize <code>useContext</code> hook (or a <code>Context.Consumer</code> component, but I don't know why anyone would choose it over the hook today). There's nothing especially wrong with <code>useContext</code>, but we can do so much better with a custom <code>useAdaptivity</code>!</p><p>If <code>useContext</code> is used outside <code>Provider</code>, you're left with either a static default value from <code>createContext</code> or cryptic <em>can't read property width of null</em> errors. Sometimes it's enough, but <code>AdaptivityContext</code> is supposed to be dynamic, and we get a lot of "bug reports" that are fixed with a "did you forget the provider?". A custom <code>useAdaptivity</code> gives us two stronger options:</p><ol><li>Show an explicit error message, like <code>console.error('useAdaptivity must be used inside AdaptivityProvider')</code></li><li>Give each component an independent size observer, and make <code>AdaptivityProvider</code> optional for advanced optimizations and overrides.</li></ol><p>Next, <code>useContext</code> has a 1:1 relationship to contexts. Fixing <code>AdaptivityContext</code> performance problems involves splitting it into two separate contexts — a frequently-changing one for <code>width</code>, and a more stable one for <code>isMobile</code>. <code>useAdaptivity</code> can subscribe to both contexts — it won't have any performance benefits, but it's backwards compatible and allows users to gradually update their apps to the new API:</p><pre class="language-jsx"><code class="language-jsx"><span class="token keyword">const</span> <span class="token function-variable function">useAdaptivity</span> <span class="token operator">=</span> <span class="token punctuation">(</span><span class="token punctuation">)</span> <span class="token operator">=></span> <span class="token punctuation">{</span><br> console<span class="token punctuation">.</span><span class="token function">warn</span><span class="token punctuation">(</span><span class="token string">'Please migrate to useMobile or useViewport for better performance'</span><span class="token punctuation">)</span><span class="token punctuation">;</span><br> <span class="token keyword">const</span> viewport <span class="token operator">=</span> <span class="token function">useContext</span><span class="token punctuation">(</span>ViewportContext<span class="token punctuation">)</span><span class="token punctuation">;</span><br> <span class="token keyword">const</span> mobile <span class="token operator">=</span> <span class="token function">useContext</span><span class="token punctuation">(</span>MobileContext<span class="token punctuation">)</span><span class="token punctuation">;</span><br> <span class="token keyword">return</span> <span class="token punctuation">{</span> <span class="token operator">...</span>viewport<span class="token punctuation">,</span> <span class="token operator">...</span>mobile <span class="token punctuation">}</span><span class="token punctuation">;</span><br><span class="token punctuation">}</span><span class="token punctuation">;</span></code></pre><p>Custom <code>useAdaptivity</code> hook also allows for an alternate context injection mechanism, like <a href="https://github.com/dai-shi/react-tracked" target="_blank" rel="noopener">react-tracked</a>. You can even bind to a global state manager instead of context. Nothing about <code>useAdaptivity</code> implies that it has anything to do with contexts!</p><p>So, a custom <code>useAdaptivity</code> hook gives us a lot of freedom — we can modify the contexts as we wish, replace them with other state management mechanism, and we can handle a missing provider as we see fit. That's convincing. What about <code>Provider</code>?</p><h2>Wrap Context.Provider, too</h2><p><code>React.createContext</code> gives you a <code>Context.Provider</code> component you're supposed to use for passing a context value. It lacks some important features, but we can easily fix that by wrapping it into a custom <code>Provider</code> component.Frankly, it's less of a concern than <code>useContext</code> — you often have a single <code>Provider</code>, and it has to be located in <em>some</em> component, so you can't go too wrong. For completeness, here's what I normally do with a custom <code>Provider</code>.</p><p>Raw <code>Context.Provider</code> with object context is a performance hazard — if you don't stabilize <code>value</code> reference yourself, every context consumer will re-render on every <code>Provider</code> render, because React updates them every time context value changes under strict equality. I don't know why this feature is not in react core, but it's one good reason to have a custom provider (see my <a href="/2021/04/05/useref-usememo/">post on custom memo</a> for details on <code>useObjectMemo</code>):</p><pre class="language-jsx"><code class="language-jsx"><span class="token keyword">const</span> <span class="token function-variable function">AdaptivityProvider</span> <span class="token operator">=</span> <span class="token punctuation">(</span><span class="token parameter"><span class="token punctuation">{</span> children<span class="token punctuation">,</span> <span class="token operator">...</span>context <span class="token punctuation">}</span></span><span class="token punctuation">)</span> <span class="token operator">=></span> <span class="token punctuation">{</span><br> <span class="token keyword">const</span> contextValue <span class="token operator">=</span> <span class="token function">useObjectMemo</span><span class="token punctuation">(</span>context<span class="token punctuation">)</span><span class="token punctuation">;</span><br> <span class="token keyword">return</span> <span class="token punctuation">(</span><br> <span class="token tag"><span class="token tag"><span class="token punctuation"><</span><span class="token class-name">AdaptivityContext.Provider</span></span> <span class="token attr-name">value</span><span class="token script language-javascript"><span class="token script-punctuation punctuation">=</span><span class="token punctuation">{</span>contextValue<span class="token punctuation">}</span></span><span class="token punctuation">></span></span><span class="token plain-text"><br> </span><span class="token punctuation">{</span>children<span class="token punctuation">}</span><span class="token plain-text"><br> </span><span class="token tag"><span class="token tag"><span class="token punctuation"></</span><span class="token class-name">AdaptivityContext.Provider</span></span><span class="token punctuation">></span></span><br> <span class="token punctuation">)</span><span class="token punctuation">;</span><br><span class="token punctuation">}</span><span class="token punctuation">;</span></code></pre><p>Just like <code>useContext</code>, raw <code>Providers</code> have a 1:1 relationship with contexts, making it harder to split / merge the contexts. To fix the coupling of <code>width</code> and <code>isMobile</code> updates, we must split <code>AdaptivityContext</code> into two parts. Easy with a custom provider:</p><pre class="language-jsx"><code class="language-jsx"><span class="token keyword">const</span> <span class="token function-variable function">AdaptivityProvider</span> <span class="token operator">=</span> <span class="token punctuation">(</span><span class="token parameter"><span class="token punctuation">{</span> children<span class="token punctuation">,</span> width<span class="token punctuation">,</span> isMobile <span class="token punctuation">}</span></span><span class="token punctuation">)</span> <span class="token operator">=></span> <span class="token punctuation">{</span><br> <span class="token keyword">const</span> viewportValue <span class="token operator">=</span> <span class="token function">useObjectMemo</span><span class="token punctuation">(</span><span class="token punctuation">{</span> width <span class="token punctuation">}</span><span class="token punctuation">)</span><span class="token punctuation">;</span><br> <span class="token keyword">const</span> mobileValue <span class="token operator">=</span> <span class="token function">useObjectMemo</span><span class="token punctuation">(</span><span class="token punctuation">{</span> isMobile <span class="token punctuation">}</span><span class="token punctuation">)</span><span class="token punctuation">;</span><br> <span class="token keyword">return</span> <span class="token punctuation">(</span><br> <span class="token tag"><span class="token tag"><span class="token punctuation"><</span><span class="token class-name">ViewportSizeContext.Provider</span></span> <span class="token attr-name">value</span><span class="token script language-javascript"><span class="token script-punctuation punctuation">=</span><span class="token punctuation">{</span>viewportValue<span class="token punctuation">}</span></span><span class="token punctuation">></span></span><span class="token plain-text"><br> </span><span class="token tag"><span class="token tag"><span class="token punctuation"><</span><span class="token class-name">MobileContext.Provider</span></span> <span class="token attr-name">value</span><span class="token script language-javascript"><span class="token script-punctuation punctuation">=</span><span class="token punctuation">{</span>mobileValue<span class="token punctuation">}</span></span><span class="token punctuation">></span></span><span class="token plain-text"><br> </span><span class="token punctuation">{</span>children<span class="token punctuation">}</span><span class="token plain-text"><br> </span><span class="token tag"><span class="token tag"><span class="token punctuation"></</span><span class="token class-name">MobileContext.Provider</span></span><span class="token punctuation">></span></span><span class="token plain-text"><br> </span><span class="token tag"><span class="token tag"><span class="token punctuation"></</span><span class="token class-name">ViewportSizeContext.Provider</span></span><span class="token punctuation">></span></span><br> <span class="token punctuation">)</span><span class="token punctuation">;</span><br><span class="token punctuation">}</span><span class="token punctuation">;</span></code></pre><p>Just like <code>useAdaptivity</code>, <code>AdaptivityProvider</code> also allows you to replace context with any other state management technology — just throw a <code><StoreProvider></code> in there and you're done.</p><p>Finally, a custom provider can handle context value in a smarter way — add default options or merge with another provider up the tree. If we had both <code>width</code> and <code>height</code>, we could allow partial overrides — user could use <code><ViewportSizeProvider width={100}></code> in a narrow sidebar, while preserving the <code>height</code> value:</p><pre class="language-jsx"><code class="language-jsx"><span class="token keyword">const</span> parentViewport <span class="token operator">=</span> <span class="token function">useContext</span><span class="token punctuation">(</span>ViewportSizeContext<span class="token punctuation">)</span><span class="token punctuation">;</span><br><span class="token keyword">const</span> contextValue <span class="token operator">=</span> <span class="token function">useObjectMemo</span><span class="token punctuation">(</span><span class="token punctuation">{</span><br> <span class="token operator">...</span>parentWiewport<span class="token punctuation">,</span><br> <span class="token operator">...</span>size<br><span class="token punctuation">}</span><span class="token punctuation">)</span><span class="token punctuation">;</span></code></pre><p>Of course, you could also have a custom mechanism of auto-detecting and updating context values:</p><pre class="language-jsx"><code class="language-jsx"><span class="token function">useLayoutEffect</span><span class="token punctuation">(</span><span class="token punctuation">(</span><span class="token punctuation">)</span> <span class="token operator">=></span> <span class="token punctuation">{</span><br> <span class="token keyword">const</span> <span class="token function-variable function">cb</span> <span class="token operator">=</span> <span class="token punctuation">(</span><span class="token punctuation">)</span> <span class="token operator">=></span> <span class="token punctuation">{</span><br> <span class="token function">setDetectedSize</span><span class="token punctuation">(</span><span class="token function">getViewportSize</span><span class="token punctuation">(</span><span class="token punctuation">)</span><span class="token punctuation">)</span><span class="token punctuation">;</span><br> <span class="token punctuation">}</span><span class="token punctuation">;</span><br> <span class="token function">cb</span><span class="token punctuation">(</span><span class="token punctuation">)</span><span class="token punctuation">;</span><br> window<span class="token punctuation">.</span><span class="token function">addEventListener</span><span class="token punctuation">(</span><span class="token string">'resize'</span><span class="token punctuation">,</span> cb<span class="token punctuation">)</span><span class="token punctuation">;</span><br> <span class="token keyword">return</span> <span class="token punctuation">(</span><span class="token punctuation">)</span> <span class="token operator">=></span> window<span class="token punctuation">.</span><span class="token function">removeEventListener</span><span class="token punctuation">(</span><span class="token string">'resize'</span><span class="token punctuation">,</span> cb<span class="token punctuation">)</span><span class="token punctuation">;</span><br><span class="token punctuation">}</span><span class="token punctuation">,</span> <span class="token punctuation">[</span><span class="token punctuation">]</span><span class="token punctuation">)</span><span class="token punctuation">;</span><br><span class="token keyword">const</span> contextValue <span class="token operator">=</span> <span class="token function">useObjectMemo</span><span class="token punctuation">(</span><span class="token punctuation">{</span><br> <span class="token operator">...</span>detectedSize<span class="token punctuation">,</span><br> <span class="token operator">...</span>props<br><span class="token punctuation">}</span><span class="token punctuation">)</span><span class="token punctuation">;</span></code></pre><p>You could have amazing combinations of inheritance, auto-detection and overrides. Really, there are endless possibilities once you are the master of your context provider. Just don't settle for raw <code>Context.Provider</code>.</p><hr><p>Wrapping both the provider and the consumer of a context into custom hooks gives you a lot of flexibility:</p><ul><li>Merge and split context as you want.</li><li>Replace raw contexts with another state injection technique.</li><li>Stabilize context object value.</li><li>Introduce smart dynamic defaults for context value.</li><li>Inherit from other providers up the tree with partial overrides.</li><li>Warn or fallback on missing provider.</li></ul><p>This flexibility is crucial if you're building a library, but it also helps a lot in any non-trivial app. Hope that convinces you!
