海外TECH	DEV Community	Exploring React Relay 13’s Rust compiler	https://dev.to/logrocket/exploring-react-relay-13s-rust-compiler-9bm	Exploring React Relay s Rust compilerWritten by Samson Omojola️The Relay compiler is a GraphQL code generation tool used for React apps Previously created in JavaScript the compiler was recently rewritten in Rust In this article we ll explore its features how it works and why the rewrite was necessary Overview of Relay and its compilerThere are quite a number of GraphQL clients available in the market but Relay comes with some distinct features and advantages One advantage Relay has is that it lets you think in terms of small scopes Using GraphQL fragments in RelayFor instance when creating a component you can tell Relay to only source the specific data required inside that particular component by creating a fragment This way you never need to worry about the big picture Each component can have its own fragment and at compile time all the fragments stitch together into a query that proceeds to fetch all the needed data The concept of a fragment living inside a component along with its view code is called colocation The advantage of colocation is that there is no over fetching data which allows your application to perform better There is also no under fetching data which prevents errors that might occur from missing data Another advantage of colocation is that a component only rerenders when specifying data in its fragment changes thereby preventing unnecessary re renders Relay s data maskingRelay also provides its scope management advantage at runtime after data responds to a query with data the compiler creates data files that serve each component its own required data when the component is about to render This concept is called data masking The advantage of this is that components cannot assess data that wasn t specified in their GraphQL fragments This way changes made to a component and its data dependencies do not affect another component As one component cannot rely on another for data data masking prevents data dependency bugs and provides your application with stability Fragments can easily be used in multiple components are easy to refactor and make your application efficient Why Relay needs a compilerRelay uses a compiler to improve runtime performance and guarantee stability With Relay much of the components work and GraphQL s communication executes at build time thereby improving your application s runtime performance significantly Refetching and paginationTasks like refetching data and pagination in applications can be tricky to implement and are error prone Through Relay s APIs like useRefetchableFragment and usePaginationFragment Relay takes advantage of its compiler to automate these tasks With Relay s out of the box pagination feature you only need a few lines of code to implement pagination in your app compared to implementing it manually The compiler helps you create the custom query needed for pagination and helps you keep track of information that s often needed when paginating like data that s already loaded and the amount of data that has yet to load It hides away a lot of complexity which is great if you simply want to put a quick pagination feature together Automatic type generationThe Relay compiler also enables automatic type generation to implement type safety in your application and prevent bugs The Relay compiler optimizes performance in your application by removing redundancies in queries and as a result reduces the size of your query payload The compiler creates compact optimized queries that run your app smoothly at runtime It also helps to save your users bandwidth and improve your application s performance by excluding the schema or string representation of GraphQL fragments from your application bundle Using a unique query IDAnother way the Relay compiler helps users save bandwidth is rather than sending a long query to your application s server the compiler generates a unique query ID and uses that to source data from the server The limitations of JavaScript in Relay s compilerAs mentioned above the previous compiler was written in JavaScript According to the React Relay team JavaScript was originally picked for the compiler because it was the language that the Relay runtime and other GraphQL tools were written in But in spite of all the attempts made to optimize the JavaScript compiler its performance dwindled over time The team s biggest challenge with JavaScript was the fact that it s a single threaded language In Node js you can t run multiple threads with shared memory Although worker threads can be created to share memory with the size of schema that Relay has this method wouldn t have been efficient Why Relay uses Rust for the new compilerWith the previous JavaScript compiler as the Relay codebase grew it took increasingly more time to compile code According to the React Relay team the constant increase in the number of queries in Relay s codebase had been slowing down performance It eventually became suboptimal for the problem it was created to solve When it became obvious JavaScript wouldn t cut it anymore a number of languages which didn t have JavaScript s single thread limitations and had strong internal support were considered before landing on Rust C was eliminated for its steep learning curve and its weak memory safety Java was eliminated for not providing enough low level control and OCaml was eliminated for its inefficient concurrency In the end React settled on Rust for its speed memory safety and concurrency and with it large data structures that can be easily and safely shared across different threads The new Rust based compiler is faster has many new features and was designed with scaling in mind Features of Relay s new Rust compilerThe new compiler was created as a collection of independent modules that can be used in other GraphQL tools Basically the same modules used in the new React Relay compiler are also used internally in GraphQL tools for other platforms The compiler comes with features like TypeScript support Support for remote persisted queries The no inline directive applied to fragments to prevent them from inlining The requireddirective which simplifies null checksThe required directive can be added to fields in a GraphQL fragment to handle null values generated at runtime Take the fragment below as an example const data useFragment graphql fragment ArticleComponent article on Article tech article required action NONE title required action NONE Above you have a basic fragment requesting the titles of tech articles The required directive attached to the title field performs a null check on it If the title is null then its parent field tech article is declared null as well by Relay The same thing happens with the required directive applied to the tech article field Now the action parameter is the important part This is where you specify what you want Relay to do if it finds a null field When action is set to NONE instead of throwing an error your UI renders fine and nothing displays wherever the title value is used in your UI There are of course other options you can apply to your fields when handling null checks This feature is especially useful when performing many null checks in your code According to React Relay team the rewrite was also done to support some future plans like abstracting more common complexities in apps and shipping with more out of the box features beyond pagination One tool that was built into the new compiler but is not public yet is a VS Code extension that makes using GraphQL easier by autocompleting field names as you type and showing you information on a field when you hover over it Why many use Rust to rewrite JavaScript toolingIt seems that a lot of JavaScript tooling is currently being rewritten in Rust But why Better speed better performance and better memory efficiency Instead of the traditional garbage collection method that JavaScript uses Rust uses a much more efficient memory management system making it faster and more performant The Next js team recently added a Rust compiler to the framework to replace JavaScript tools like Babel and Terser This was done to maximize performance achieve faster builds and refresh rates Their new Rust compiler is times faster than Babel and seven times faster than Terser Fast and memory efficient Rust found a way to bring both low level control and high level comfort design to the software world Memory safety which is one of Rust s most prominent features and biggest selling points lets you easily identify and get rid of bugs at compile time We are also starting to see Rust alternatives for tooling like Prettier ESLint and Webpack spring up ConclusionRust which was voted the most loved programming language in the last six years and appears to complement JavaScript really well With JavaScript s simplicity and ease of use and Rust s speed and memory efficiency I believe both languages together would be unstoppable Full visibility into production React appsDebugging React applications can be difficult especially when users experience issues that are hard to reproduce If you re interested in monitoring and tracking Redux state automatically surfacing JavaScript errors and tracking slow network requests and component load time try LogRocket LogRocket is like a DVR for web and mobile apps recording literally everything that happens on your React app Instead of guessing why problems happen you can aggregate and report on what state your application was in when an issue occurred LogRocket also monitors your app s performance reporting with metrics like client CPU load client

Complexity	https://dev.to/itstrueintheory/why-your-css-is-always-messy-and-chaotic-understanding-css-complexity-3o94	Why Your CSS is Always Messy and Chaotic Understanding CSS ComplexityDoes the thought of making a minor style update in a large front end project give you pause It does for me It can be especially hard when I m modifying a project written by another team even if the change is small Somehow CSS stylesheets preprocessed or otherwise are always a jumbled mess of classes and ids Why is it common to have clean JS Python PHP code and spaghetti CSS in the same code base This week I want to take a look at what makes CSS complex using the ontology of software complexity from John Ousterhout s excellent book A Philosophy of Software Design This post sets the table for why CSS gets so messy before we dig into design patterns and solutions next week What is Complexity Let s start off with a complexity definition From A Philosophy of Software Design Complexity is anything related to the structure of a software system that makes it hard to understand and modify the system This definition fits CSS quite well Complex CSS is hard to understand and harder to modify obligatory link to the CSS stool joke Ousterhout also points out three symptoms of complexity that make a piece of code hard to work with Change AmplificationChange amplification occurs when a seemingly simple change requires changes in multiple places Example in CSS land  you are tasked with changing all paragraph text colors on a website from black to navy With a simple HTML page it s as simple as a one line p color navy On a large project you spend the whole day defeating the highest specificity that applies to all  lt p gt  elements on all pages only to discover the checkout gadget s shipping confirmation modal has a paragraph element that somehow inherited text color from the teal heading Cognitive LoadCognitive load is the amount of information a developer needs to keep in mind in order to make a change Example in CSS land  You are asked to change the font size of the hero section CTA button on large viewports from px to px Here s a list of information you may have to keep in mind Default body font size from user agent stylesheets Existing button font size for small and medium viewports font size of hero section text because the em unit seems like a good fit Maybe we use rem instead does the project use the standard px rem size or px rem size for ease of calculation Potential hero section variation of the button and its font size Any font size utility classes the project may have Unknown UnknownsYou face unknown unknowns when it is not obvious where to get the information needed to complete a task or where to make the necessary change Example in CSS land  You are changing the error message color for a  lt span gt  element in a login widget on the category page Do you make the change in utilities css  form css  widget css  login css  category css or index css Depending on your project s CSS methodology this could be a component variation a new component or a new utility class Why CSS gets ComplexNext let s take a look at different technical causes of CSS complexity Selector SpaceWhile CSS properties belong to a single matched element at a time CSS selectors are matched against all elements in the DOM So as a project grows in size and the number of total selectors both actual and potential grows we have a natural increase in CSS complexity The total number of CSS properties in the DOM grows linearly with DOM size a page with n total elements at x properties per element have at most nx total adjustable properties On the other hand the size of the set of potential selectors grows exponentially with respect to DOM depth Assume using only a single class per element a m level deep DOM element has  m number of applicable class based selectors Since the total number of potential selectors grows exponentially on large projects it impacts both cognitive load and change amplification to understand and modify its implemented subset If you ever wondered why front end developers spend so much time tinkering with and cursing at CSS selectors it s because the selector solution space for any given change is HUGE SpecificityIn my experience there s no quicker road to unmanageable CSS than specificity escalation Because any moderately complex project will have a huge set of potential selectors for each change and because CSS selector specificity score is additive in nature a project s average CSS selector specificity tends to increase as it grows As Chris Coyier pointed out in this answer about CSS code smell when you see a selector like  articles comments ul gt li gt a button in your dev tools it s already too late  Specificity related complexity is symptomatic in all categories We already covered the need to create ever more specific CSS selectors in the change amplifications case eventually reaching id selectors   important and inline styles Specificity escalation also means developers reading and modifying CSS now need to keep a detailed mental model of the DOM in their mind when working is it  comments inside  articles or is it  comments inside uls inside  articles Lastly ever increasing selector length means the number of locations that a style change may belong to also increases linearly In the selector example above should the change go in articles css  comments css  global css or just use find in the project  and what if you use a preprocessor that supports nested selector Source OrderCSS source order gives us a way to consistently predict how a style resolves when multiple selectors have the same specificity score It also handles when multiple values are declared for the same property in the same scope an especially tricky combination with CSS shorthands The rule is simple the value that appears last wins Straight forward right Not so fast This means each change we make is potentially affected by all other selectors with the same specificity Your  nav button could be affected by  header button In fact you need to be aware of the intersection of all sets of elements matched by each selector with the same specificity score as the one you are working on I can t even keep the entire DOM in my head at once never mind the subset matched by all stylesheets It s easy to see how this is a significant cognitive load that grows with project size Source order is an even bigger problem in large projects where multiple stylesheets are included per page either plain CSS or via preprocessor imports Assume you are changing the color of the span in the following BEM based DOM structure to green lt div class widget gt lt div class widget content gt lt div class media box gt lt span class media box label gt Change Me lt span gt lt div gt lt div gt lt div gt and the CSS files widget css widget widget content color red media css media media label color blue If you have no guarantees on the order of the stylesheet imports which file do you change This is a clear case of unknown unknowns and it grows linearly with project file size Do you change both just to be safe and thus engage in change amplification Or do you write  widget widget content media box and engage in specificity escalation InheritanceCSS inheritance governs how certain CSS properties when not specified inherit values from their parent elements Some common properties that inherit include color  font size and line height Inheritance is not as problematic as the other issues covered so far It s a layer of abstraction that has little impact on change amplification and does not produce unknown unknowns What it does is lead to additional cognitive load even if the issues are mostly discovered via the browser can you picture what hello world in the below example look like lt div class a gt lt div class b gt lt div class c gt lt div class d gt lt p gt Hello World lt p gt lt div gt lt div gt lt div gt lt div gt a color blue font size px letter spacing px line height b font size px font weight letter spacing px c color teal font weight font family Serif d font size px font family arial Final WordI hope I ve convinced you that CSS is inherently complex and its complexity grows superlinearly with the size of your project Next time you get frustrated with a design change that seems to take much longer than it should know it s probably caused by the project s CSS complexity Next time you see a long selector in a code review call it out and nip specificity escalation in the bud And if you are starting a new project I hope this post has further convinced you to adopt a tried and true CSS methodology and enforce it really enforce it No need to make CSS more complex than it has to
