海外TECH	DEV Community	Frontend performance pattern	https://dev.to/thanhlm/frontend-performance-pattern-19o7	Frontend performance patternOriginal post Why should you read this Common patterns use to optimize frontend performanceBoost your web app speedConvince your boss and colleague When should I care about performance First of all let s make an agreement that whenever we design a system structure for an app it means that we re making trade offs We cut some parts to gain others in order to make the system fit with the problem What if we want all It s impossible because resources when kick off the project is always limited however the problem on the opposite can grow endlessly Centralize vs DecentralizeMonolithic vs MicroserviceSSR vs CSROOP vs FPSQL vs No SQLLanguage X vs Language YAPI vs GraphQLStream vs BatchThen when should I care about performance And which is the trade off For me a frontend app has to maintain aspectsFunctional Your app must run with correct logicMaintainable Readable If it run right then it should be easy to maintain and add a new featurePerformance it should be fast delight the user journeyFunctional is easy to understand it is the only aspect that we can not make a trade off Then now our application becomes a slider between clean code vs performance it s depended on each project and the problem to trade offYou are a guy in the project so you have the right to know which is more important Do you want to launch many features at a fast pace or do you want the feature is running lighting fast I was really obsessing with performance and had a chance to see that many juniors got the same obsession as me Once upon a time I spend a day paralleling a script that validates the CSV file The optimization looks good reduce the time from minutes to minutes Sadly the script run only time a week and in turn it can only save about minutes a month on a free server Performance patternHere are some common patterns used to optimize performance And because it is quite popular so it s quite easy to apply for your project which our sacrifice much on Maintainenable Readable Split code LazyloadDifficulty EasyWhen to apply As soon as the project start we can start with a simple one like split code by pages routes After that if you want to take this further you can split the code by user interaction Spell Only load what users needHow It depends on your framework so search Google with this formula Framework code splittingExample on ReactCode Splitting Reactimport React Suspense from react const OtherComponent React lazy gt import OtherComponent function MyComponent return lt div gt lt Suspense fallback lt div gt Loading lt div gt gt lt OtherComponent gt lt Suspense gt lt div gt Prevent installing the duplicated libDifficulty Quite EasyWhen to apply When you start thinking about installing a new library Then we have options If you use existing lib pray it to fit with your problemIf you use new lib change the legacy code and pray it to fit with the legacy problem testing for regression bugsUse both libs ⇒ONLY this is your last hope like your PM is hanging a knife on your neckIn my current project we have libraries to handle date time momment date fns vàdayjs Which moment and date fns is big bundle size You might not need date fnsSpell Check packages json before searching installing new libraries Choose the library that supported ES and tree shakingDifficulty Easy but depends on communityWhen to apply All the time Bundle size and tree shaking support should be important points to consider Spell The newer library the more chance it is better But it does not guarantee that it is stable and correctly How Check library on redux bundle size is kB when Gzip and supported tree shakingMinimizing bundle size MUI Debounce user inputDifficulty Quite easyWhen to apply When we re hooking user typing scrolling event which some tasksSpell Search input ⇒DebounceDebounce Your Input Handlers Web Fundamentals Google DevelopersIn more advantage cases we can use debounce for API response A common case is to debounce the response for trading order book on weak computers Add loading lazy for tag img iframeDifficulty EasyWhen to apply Most of the time you see img tag unless you are sure that the img is above the foldSpell Image loading lazy ⇒️ lt img src F Fs us west amazonaws com Fsecure notion static com Feedb d a ba eebb FScreen Shot at PM png table block amp id ab ae bc bad dbda amp cache v loading lazy alt Nimbus gt Memorized functionDifficulty NormalWhen to apply When your function drain lots of CPU and RAMSpell Cache the expensive taskHow to use Memoize to cache JavaScript function results and speed up your codeIn addition you can use Web Worker to push those computations into background processesconst cachedResult useMemo gt CPU intensive task here dependencies Cache frontend assets using Service WorkerDifficulty Normal hard It s quite hard when starting but the result is worst itWhen to apply When you are working in a really big app bundle size is huge likes complex Admin CRMSpell Complex big web app ⇒Service WorkerExample in ReactReact PWA with WorkboxTrust me after you have done this users will only ever see the loading indicator for the beginning After that you can update the app in the background I will go into detail about how I do it in another post Virtual listDifficulty HardWhen to apply When you have a list containing lots of items Users have to scroll a while to view all itemsSpell You have a table more than items you are building something like feed on Facebook Twitter ⇒Virtual listReact VirtualI highly recommend this one Supper power and lightweight Forget outdated react window react virutalize When working with Virtual list developers should know about the concept how it works and also when the component is rerendered to take full power from it If not you re shooting on your foot Break long run functions into multiple short run functionsDifficulty HardWhen to apply When you run the function and your laptop hangs Spell Like AboveHow You break your long run CPU bound function into multiple short run functions with setTimeOut requestAnimationFrame However when breaking long run functions into many small ones is not an easy task sometimes your need to keep those functions running sequentially to make sure the function is always correct Optimistic updateDifficulty Easy normal hardEasy when you apply for simple entityNormal when those entities start conflicting with local and server and you need to solve the conflictHard when the logic is quite complex and you have also to deal with solving the conflict on local state and server stateFor eg The like button is easy the comment is normal and posting a status is a really hard caseWhen to apply When the feature is quite simple The success rate of the API is about Spell Simple logic success ⇒Optimistic updateCheat Code for a Lightning Fast Front End Building an Optimistic UI Lazy polyfill Dynamic polyfillDifficulty Normal hardWhen to apply When you re too tired don t have any other option to optimizeSpell When you see that the polyfill bundle size is quite huge but users are all high techHow Leading right now is Polyfill io However it is quite hard because you need to know how to set up in both frontend and backendWhich is the pattern that you use to optimize performance let me know I m excited to explore more	2022-02-18 03:57:41
