Learnings from React Conf 2021 |
https://dev.to/alexeagleson/learnings-from-react-conf-2021-17lg
|
Learnings from React Conf I recently had the opportunity to join the digital React Conf and listen to some talks from a really great list of speakers This post aims to summarize in many ways for myself the big take aways that I learned from the conference For example there were some great talks on design UI that I found interesting but since I am more involved with the coding side those will be the areas that I focus on primarily So without further preamble here s an unordered list of some of the new topics I found most compelling Conference Video LinkReact Release CandidateUpdating to React Suspense and Server ComponentsReact DocsUnusual React EnvironmentsCross Platform with React NativeDeveloper ToolingThe Future of MemoizationShopify s HydrogenAll the RestBonus TipsWrapping Up Conference Video LinkThe entire hour conference is currently available on Youtube for anyone to watch for free Note they have stated they will be releasing individual videos of each talk so it is possible this video link will go down in the near future I will aim to update links to the individual talks if that occurs React Release CandidateThe official release candidate for React was released to coincide with the start of the conference This version is considered to be the expected version for the official release in early barring any major issues found in the next couple of months So although you may not want to upgrade your critical production applications just yet as of today React v is as close as its ever been to finalized You re definitely encouraged to use it from the get go with any new projects you create Of course the big topic of discussion in the conference were focused around the new features of React itself Updating to React Run the following command in your existing React project npm install react beta react dom betaNote that as of today you can also install the RC version rather than beta as is now a release candidate Check the versions on NPM to see what is available Then all you need to do is change the app mount point presumably in your index file from const container document getElementById root ReactDOM render lt App gt container To const container document getElementById root const root ReactDOM createRoot container root render lt App gt And you re ready to begin working with React Suspense and Server ComponentsSuspense is already available in React you may have worked with code before that looks like this const MyComponent React lazy gt import MyComponent const App gt return lt Suspense fallback lt Loading gt gt lt MyComponent gt lt Suspense gt However this use of code splitting with Suspense is happening on the client side where development is driven now is implementing Suspense on the server side Currently SSR server side rendering is an all or nothing approach If we have a page with a header nav content and comments that we are generating with SSR then the time it takes to serve that page will be equal to the slowest of its individual components If every other component takes s and comments takes s then you still need to wait for comments before the app can be sent to the client This is no longer true with React server components It s now possible that despite being rendered on the server you can wrap your lt Comments gt in a lt Suspense gt with a fallback loading spinner or whatever you want and the app will be sent with the fallback in place until it is ready Once it is ready the bundle containing the rendered comments will be sent to the client to replace the fallback component As a bonus the React is smart enough to watch for user interaction If one suspended component has been clicked while it s still loading React will immediately stop what it is doing elsewhere and prioritize the loading of that component The key takeaway for server components is that they are always rendered on the server and never sent to be rendered on the client There are two critical take aways from this Server components will have no impact on your bundle size since they always render on the serverServer components can have direct access to your databaseIf you would like to learn more about server components here s a great talk from Dan covering all the details And if you would like to see Suspense in action Dan Abramov of the React team has created a codesandbox example Hit the refresh button to see the effect You ll want to open the full link in another tab to see the example of the code and how it s composed React DocsThe React documentation has finally been modernized with hooks first content They ve already been released in beta and are planning to be released officially to replace the current documentation when React ships Discussion of the new React docs starts around Unusual React EnvironmentsI really enjoyed Sarah Rainsberger s talk which focused on unusual development environments for React My wife has been working with React this year for the first time and really connected with this talk particularly the idea that someone would be able to learn React and its concept without necessarily having to go through a prerequisite stage of learning command line tools NPM etc Thanks to online coding environments like codesandbox glitch and repl it for example you can begin writing real programs in React in a few seconds without installing any dependencies and that s really powerful One of my favourite trends in conferences I ve seen is the push to include speakers who are relatively new to the technology talking about their experiences and aimed at new developers in similar positions It helps a lot to break down the walls that people often hit when they are overwhelmed with the amount of new tools and concepts they need to learn when getting started The talk begins around Cross Platform with React NativeThe React team seems to be really pushing for parity of developer experience between all kinds of platforms There was a lot of talk about what React Native is being used for these days and how optimizations being applied for one platform Android for example end up being applied to other platforms iOS in ways that they were not expecting They discuss how React Native is being used to develop native experiences on not only mobile platforms but OS s like Windows parts of the Microsoft Office suite and Xbox the dashbaord for the new Xbox Series X as well Here s an image that really demonstrates what they are trying to achieve If you want to watch it yourself this talk starts around Developer ToolingThere was a lot of focus on new and coming updates to developer tooling for React with a talk from Brian Vaughn He summarized the big focuses the tooling will be seeing in the coming months Integrating the profiler and timeline to work togetherReact Native supportCPU and memory profilingThis talk starts around The Future of MemoizationOne of the most interesting talks that at times went completely over my head was from Xuan Huang about the future of memoization in React In the context of React memoization is used primarily to indicate to React which components may or may not need to re render depending on some kind of state Typically for a component you can explicitly state that if the props do not change you do not need to re render the component More info on React memo With the useMemo hook we can create a memoized value that will not be recalculated if values in the dependency array do not change Setting up this kind of scenario is notoriously cumbersome sometimes requiring the use of a lot of extra code and potentially the useEffect hook to achieve your goal It also has the unfortunate side effect of making the flow of your code less linear less likely to follow logically from top to bottom Xuan s talk demonstrated this concept by showing an example in real time then did a and started writing a theoretical example of how it could look To be hones the new example looked a lot more complicated than the original But he brought it all together by explaining that all the code he was writing if everything goes well this idea is still in development could be handled for you automatically A tool that detects areas where memoization would help optimize your components and be applied automatically Crazy stuff Check it out yourself the talk begins at Shopify s HydrogenShopify is part of the React Server Component working group and has bet heavily on the power of server components for their new React framework called Hydrogen Hydrogen is a brand new React based framework designed to unify the combination of server components smart caching and Shopify s API Shiopify maintains their own documentation on Hydrogen s support for React server components which they claim to maintain their own stable abstraction layer over server components so you can use them with confidence despite their current state All the RestThere were still more talks Some I missed simply due to time constraints or lunch or kids or whatnot others were outside the scope of the work I normally do though I m always interested in learning anyway even if it s not directly applicable Either way I d encourage you to check out some of the other talks React for DesignersAccessibility in ReactUsing External StoresRelayJapanese FormsReact Working GroupsMachine Learning and React Native Bonus TipsHere s a couple simple and practical things I picked up that are easy to pick up and use today Like most of the talks these are new features of React Fortunately the upgrade path to React is aimed to be very simple and completely backward compatible See the section at the start of this post on React Update for a simple example of how to make the update in a couple of lines BatchingPrevious state updates would always be batched into a single render even if they were called multiple times in a row There was a limitation for this however if the function calling these state updates was asynchronous the updates would not be batched This is no longer true as of React The below code example in v would trigger two separate state updates in v they will be batched together fetchFromApi then gt setLoading false setError false Deferred StateOne of my favourite new hooks I learned about that I thought was great was the useDeferredValue hook The first time they showed it in Shruti Kapoor s talk I thought it was fantastic Not surprisingly it kept coming up at least another times in other talks as it seems to be extremely useful in a lot of scenarios Basically what it does is allow you to specify a piece of state that you know will take longer to process than the other state of the component and allow the component to render itself without waiting for the big one When the big one is ready it will render that one in To give an example large lists usually meet this criteria If you have a filter button that changes the state of a large list of items being rendered The below example comes from the React documentation on the feature function App const text setText useState hello const deferredText useDeferredValue text timeoutMs return lt div className App gt Keep passing the current text to the input lt input value text onChange handleChange gt But the list is allowed to lag behind when necessary lt MySlowList text deferredText gt lt div gt Wrapping UpI hope you learned something from this post and I hope you get the chance to check out some of these talks Please check some of my other learning tutorials Feel free to leave a comment or question and share with others if you find any of them

NES and SNES creator Masayuki Uemura dies at It s a sad moment for gamers Kotakureports Masayuki Uemura the lead creator of the Famicom and Super Famicom aka NES and SNES died on December th at the age of He started working at Sharp where he sold solar cell and light sensor technology but he s best remembered for a long and highly influential run at Nintendo that effectively revived the video game industry following the crash Uemura first became involved with Nintendo after the company s Gunpei Yokoi asked about using Sharp solar cells to produce light gun games The future console designer joined Nintendo in and the company released gun games that included a home friendly game called Duck Hunt yes the predecessor of the NES title Company president Hiroshi Yamauchi put Uemura in charge of the R amp D division responsible for hardware including consoles and in November famously called Uemura asking him to build a machine that lets you play arcade games on your TV The result was s Famicom the system that would become the NES outside of Japan You know at least some of what happened next The Famicom and NES were wild successes selling nearly million units combined and rejuvenating interest in home consoles Uemura then led work on the Super Famicom whose global launch as the SNES further cemented Nintendo s reputation He also produced some NES games including Ice Climber and three sports titles He retired from Nintendo in but continued to serve as an advisor and would go on to teach and research video games as a professor at Ritsumeikan University It s hard to overstate Uemura s influence The video game business as it exists today arguably owes much to the skill of Uemura and his team when they designed their first TV consoles He also helped grow Japan s overall tech industry by making Nintendo a global force in electronics While he certainly wasn t the only star at Nintendo he was one of the most directly influential |
