海外TECH	DEV Community	React Router and nested routes	https://dev.to/imkevdev/react-router-and-nested-routes-fmn	React Router and nested routesCross posted from Following the public launch of Remix v nested routes have become all the rage at least within my tiny corner of cyberspace But what are nested routes why are they meaningful and how can you use nested routes in your React app React RouterNested routes have existed in React Router since very early on heck it was initially named react nested router Now on version React Router is one of the most popular React packages and will be used throughout this post to demonstrate the concept of nested routes I will also include React Router v code samples and demos but I will refer to the v version when explaining the code Nested routesIn my own words a nested route is a region within a page layout that responds to route changes For example in a single page application when navigating from one URL to another you do not need to render the entire page but only those regions within the page that are dependent on that URL change In the wireframe above when clicking on a header link the main content will be rendered to show the content for this route while the header remains unchanged Similarly when clicking on the left navigation links the page s content section will update to show the new content but the header footer and navigation menu remain unchanged This layout could be implemented in several ways export default function App return lt div className app gt lt BrowserRouter gt lt Routes gt lt Route path catalog id element lt Catalog gt gt lt Route path catalog element lt Catalog gt gt lt Route path welcome element lt Welcome gt gt lt Route index element lt Home gt gt lt Routes gt lt BrowserRouter gt lt div gt Flat routing structure v Flat routing structure vIn the above flat structure we have four routes declared in a single file catalog id and catalog would render the lt Catalog gt component which includes the left navigation and the content area If the id param is present then it would show the content for that id if not it would show some default content welcome shows a welcome message and the final catch all route shows the home page including the lt Header gt and lt Footer gt Navigating between the different routes would cause the main section to render with the updated content This includes the lt Header gt lt Footer gt and lt Nav gt even if they are not changing If you play around with the demo you will probably feel that it works well is snappy and there are no glaring bugs This routing structure is fairly common and I have personally encountered it numerous times on production However this structure is not optimized and when navigating from one URL to another the CPU is doing a lot of work that it doesn t need to In our example this overhead is negligible but on a more complex application it may result in visible jank amp deteriorate the user experience To make re renderings more apparent I have added the following code snippet but initially left it commented out If you are sensitive to flashing images please use caution React useLayoutEffect gt if ref amp amp ref current ref current style background color faaa setTimeout gt ref current style background color none Let s get nestedThe above routing structure could be optimized by using nested routes to avoid rendering components that have not changed As a default rule we only want to render what has changed When a user clicks on the left navigation links the only component we want to render is the content section Similarly when a user clicks on a header link we only render the main section export default function App return lt div className app gt lt BrowserRouter gt lt Routes gt lt Route path welcome element lt Welcome gt gt lt Route path element lt Header gt lt Routes gt lt Route path catalog element lt div className two column ref ref gt lt Nav gt lt div className content gt lt Routes gt lt Route path id element lt Content gt gt lt Route index element lt p gt Use the left nav to selet a catalog item lt p gt gt lt Routes gt lt div gt lt div gt gt lt Route index element lt Home gt gt lt Routes gt lt Footer gt gt lt Routes gt lt BrowserRouter gt lt div gt Nested routes v Nested routes v Instead of having three routes on a single level we now have six routes spread over three levels At the topmost level we have two routes path and path welcome These two routes were separated because the lt Header gt and lt Footer gt are not visible on the lt Welcome gt page On the second level we have two routes path catalog and index These are used to render the lt Catalog gt or lt Home gt respectively As you can see in the code snippet above the lt Header gt and lt Footer gt are included in the element attribute for path instead of being declared within lt Catalog gt and lt Home gt as we had done in the flat structure Finally on the inner most level there are two more routes The first path exposes the id param with path id Since this route is a nested route of path catalog then the path is built onto its parent s matching in catalog id The index route is used when no id is present If you experiment with the demo you will see that each component is only rendered when needed making this solution much more optimized than the one we saw earlier I love it ConclusionNested routes aren t a new concept If I remember correctly I was using some form of nested routes way back in on C s MVC framework it s been a while so let me know if I m mixing things up Yet I still encounter cases when developers opt for a flat structure when nested routes would be the better solution While I believe that nested routes could help you today I expect that nested routes would become even more important in the near future with concepts such as Islands Architecture and frameworks like Remix gaining traction Give it a go and you won t turn back Thank you for reading amp have a good one

海外TECH	DEV Community	This Week In React #92: Remix, MDX 2, Lifetime Analysis, Story of React, Quick Start Docs, TypeScript, Node.js, Deno...	https://dev.to/sebastienlorber/this-week-in-react-92-remix-mdx-2-lifetime-analysis-story-of-react-quick-start-docs-typescript-nodejs-deno-50mj	This Week In React Remix MDX Lifetime Analysis Story of React Quick Start Docs TypeScript Node js Deno Hi everyone Trending this week the convergence of frameworks and tools using standard web APIs Remix Deno Node js MDX v freshly released exciting for interactive content authors Quite calm on the React Native side A good amount of TypeScript content It s exciting to see Vercel continues its investment to bring us faster DX porting tsc and hiring NAPI RS creator The plan is indeed to cover all the build pipeline including replacing Webpack  Support the newsletter     Recommend it to your friends it really helps  Sponsorise This Week In React  Write testimonials on Twitter  Retweet the latest Twitter thread  Reply to this email  feedback is welcome ReactRemix Not Another Framework Remix builds on top of Web standard APIs Ryan Florence can t predict if Remix will stick but gives good reasons to learn it the knowledge you acquire won t be lost It s like React no need to learn another templating language and the JS knowledge you get by using JSX remains usable in many other places Remix is also designed to be framework agnostic On Twitter  Ryan Florence teases us on the next possible targets for Remix I bet on Qwik and Solid I increasingly see Remix as a potential gateway to Deno also based on web APIs and possibly the next framework to outlive React Unrelated  Kent C Dodds had a serious car accident MDX Official launch for MDX This technology permits to interleave Markdown and JSX quite easily very convenient to create interactive content ie Josh Comeau s website Docusaurus v improves on many things fixes a few syntax problems significantly improves performances can support other frameworks Lifetime Analysis for React Component ArchitectureAlan is inspired by the concepts of lifetime analysis and ownership of objects in Rust to deduce where to put his React state I feel like I do exactly this intuitively Original reading a little verbose initially but this makes sense at the end No need to understand Rust Creating a Schema Based Form SystemTania explains how to drive the rendering of a React form with a JSON schema The example is based on Formik and Yup but it is above all the technique that matters and can be useful for integration with a CMS or backend that sends you such schema Extras Dan Abramov rewrote the React Quick Start docs  beta site and it looks great  The Story of React nice retrospective on the story of React from JQuery Backbone to Next js Remix Pause Your React App with Breakpoints for those still using console log  react zorm new React form lib uncontrolled typed and based on Zod leveraging web APIs FormData to integrate nicely with Remix The baseline for web development in those stats on the web got the ecosystem talking this week React doesn t have such good scores and in particular Next js beaten by Gatsby on Core Web Vitals   Over fetching means three things to me on the advantages of GraphQL with Relay compared to modern alternatives Remix loaders Next js getServerProps tRPC  Next js avoid returning too much data in getStaticProps and getServerProps Recoil React concurrent rendering strict mode Docusaurus beta nice release SWR supports  mjs  optimistic UI auto error rollback Gatsby v  Nx ️Remix Atomic design and storybook SponsorsStream powerful Chat amp Feeds for React amp React NativeStream is the maker of enterprise grade APIs and SDKs that help product and engineering teams solve two common problems at scale  in app chat and social activity feeds With Stream developers can integrate any type of messaging or feed experience into their app in a fraction of the time it would take to build these features from scratch  Stream Chat makes it easy for developers to integrate rich real time messaging into their applications Stream provides robust client side SDKs for popular frameworks such as React  React Native Flutter Android Angular Compose Unreal and iOS It also supports Expo managed workflow Unlock enterprise grade features functions and UI components completely free for your startup or side project with the Maker Account React Native React Native Versions TIL about this tool to know usage of each React Native version Expo SDK Might be useful to convince your boss to upgrade Deep dive into React Native s New Architecture introduce pieces of the new architecture JSI Fabric Turbomodules Codegen   We will be focusing a lot on Expo web this year exciting Demo React Native Skia  shaders  path interpolations  React Native Performance ️ RNR Behind Our Decision to Cancel Chain React Partners Start React Native learn everything about gestures and animations with William Candillon React Native Weekly stay up to date React Native core updates TypeScript Weekly the best TypeScript links every week right in your inbox ES next News learn about the latest in JavaScript and cross platform tools Tailwind Weekly all things Tailwind CSS new issue every Saturday Gi pre vetted remote React amp React Native developers you can trust on contract or full time basis Infinite Red US React Native experts making your idea a reality Software Mansion the co creators of React Native and the technological core of many tech companies OtherPorting tsc to Go not Rust With the arrival of new bundlers type checking becomes the bottleneck in larger codebases Donny Vercel is the author of SWC  Rust He attempted a complete rewrite in Rust POC compiles x faster than tsc but it s a lot of work compared to a port that would draw on existing tsc code Problem the tsc codebase is difficult to port to Rust shared mutability GC and Go is better suited for this specific task The plan of SWC and Vercel is clear they will provide us fast tooling for the everything we need transpilation typechecking minification and bundling About porting tsc another alternative in Rust exists  tyty  but for the moment it s a side project not yet open sourced Deno in Deno shares its retrospective with improvements on the core opcalls perf FFI their Deno Deploy service V isolates comparable to Cloudflare good target for Remix I m excited about the compatibility with web APIs and Node js compat mode With Node js gradually implementing web APIs see below we might be able to switch from one to the other more easily through meta frameworks like Remix Extras Node js v will support fetch natively   JSON modules unflagged and maybe a new API Response json Node js debugging and error handling with Error Cause nice introduction to this ES feature Trailing Slashes on URLs Contentious or Settled my analysis on trailing slashe  done for Docusaurus seems useful for the community Zach Leatherman Eleventy Netlify presented it in a more appealing way This should also help Gatsby  V v Intl improvements prettier plugin tailwindcss to sort classNames Updates from the th meeting of TC not much Note there s an enum proposal  stage Turborepo v allows in particular to create dependencies on env variables The TypeScript converging point   Can we express every JavaScript program through TypeScript types  Stefan answers  Not yet  and explains limitations by typing the CLI package commander
