海外TECH	DEV Community	React to Elm Migration Guide	https://dev.to/jesterxl/react-to-elm-migration-guide-30np	React to Elm Migration GuideThis guide will help you learn and migrate to Elm with assumption you already know the basics of React The Elm guide is great and will give you a thorough understanding of everything you need to know in a good order This guide is different Instead we re going to start with the fundamentals of JavaScript amp React and how you d do the equivalent if any in Elm If you already know React we ll use those firm groundings so you can feel more comfortable

framework in that it provides many fundamentals needed to build applications There is enough features that you can adopt that it is a sliding scale Just want JSX and variables Cool Want a Context to emulate Redux Cool Want to swap out the render for something like Preact Cool Modular to add and swap out parts with large community support to modify it to suit your needs It s assumed you can write React in JavaScript There are basic runtime typings enforced for component properties built into React If you want something more TypeScript support has been added as well A popular project create react app rose in popularity because of it s ability to handle the compiler toolchain for you Teams do not have to know about Webpack or JavaScript build targets such as CommonJS ES or ES While they don t have to maintain the core for cyber security findings or build reasons you the team will still have to upgrade more than you might want to Out of the box you get a simple development environment with the ability to save a file and see it live reload Tests are setup and ready to go Finally a production build with all kinds of optimizations are there Having simple basic commands of start test and build give you all you need to build most apps While you can utilize npm yarn is supported for those who want additional features that yarn provides Top What is Elm Elm is a strongly typed functional language compiler package manager and framework You write in the Elm language and it compiles to JavaScript for use in the browser The Elm compiler has basic modes of development and production It optionally has a REPL if you want to test some basic code The package manager uses it s own website and structure using elm json instead of package json The framework is what Elm is most known for and was the inspiration for Redux You code in Elm in the Elm framework install Elm libraries and compile using the Elm compiler into JavaScript Most learning apps will compile to an HTML page which includes the JavaScript and CSS automatically For more commonly advanced applications you ll just compile to JavaScript and embed in your own index html This often works better when you want to do additional HTML and CSS things to the main HTML file There is a create elm app but it tends to violate the Elm philosophy of not using complex hard to maintain JavaScript build tool chains

Top Thinking In ReactReact s always been about the ease of creating components then composing those components together into an application Look at a UI see the seems in your mind and decide who will manage the various pieces of state MockComponent HierarchyRepresent UI StateDetermine Where State Lives Mock DataIn React you ll mock the data you get from the potential back end API or back end for front end that you ll build Below we hard code some mock JSON so our components can show something and we can visually design amp code around this data category Sporting Goods price stocked true name Football category Sporting Goods price stocked true name Baseball category Sporting Goods price stocked false name Basketball category Electronics price stocked true name iPod Touch category Electronics price stocked false name iPhone category Electronics price stocked true name Nexus Component HierarchyNext you ll either create components from that data that you ll represent and see how each is a component with it s own ability to represent the data visually and possibly handle user input…or do the same to a design comp given to you by a designer Whether that s the small components in the tree or the bigger ones who bring it all together that s up to you Typically you ll either eyeball the data and the components will start to visualize in your mind OR you ll see the design comp and start to slice the various parts into a component tree in your head FilterableProductTable orange brings all components togetherSearchBar blue receives all user inputProductTable green displays and filters the data collection based on user inputProductCategoryRow turquoise displays a heading for each categoryProductRow red displays a row for each product Represent UI StateThird you ll think strongly about state if you didn t “figure out out going through Step Most data can be props but if a component is controlled perhaps it may have it s own state that would help it interact with other components Favor props but use state where you need to encapsulate it into components Whether using an Object Oriented class based approach or a Functional one often components will contain things you feel it s best for them to manage internally Determine Where State LivesLastly identify who owns the source of truth While many components can have their own internal state the “state of the app is typically owned by one or a select few The interactions between these components will help you sus out where it should probably live and how you ll manage it events Context Hooks Redux etc Top ElmWhile many myself included wish to immediately jump to building components Elm encourages thinking hard about your Model first Elm s types allow you to make impossible application states impossible and simplifying how you represent things The good news if you screw this up the Elm compiler has the best error messages in the industry and allows you to refactor without fear Model DataComponent HierarchyModel Data ChangesHandle Events Model DataStep is to model your data using Elm s type system Like React some will either be dictated like an API or it s something you can customize from a BFF However this can be heavily influenced by your Designer s comp as well type alias Product category String price String stocked Bool name String type alias Model products List Product initialModel Product category Sporting Goods price stocked True name Football Product category Sporting Goods price stocked True name Baseball Product category Sporting Goods price stocked False name Basketball Product category Electronics price stocked True name iPod Touch Product category Electronics price stocked False name iPhone Product category Electronics price stocked True name Nexus Component HierarchyAlmost the exact same as React except there is no state in components all state is your Model Your FilterableProductTable SearchBar etc are just functions that often take in the model as the first and only parameter Model Data ChangesEven if you use Redux in React you still reserve the right to occasionally keep internal component state Not so in Elm all state is in your model That means your SearchBar blue would have a currentFilter String on your model to capture what the current filter if any exists You d also have a onlyInStock Bool for the checkbox In React both of those could be state in the component via this statestate in the component via FilterableProductTable that you d pass up via eventsstate in Reduxstate in a Hookstate in a shared ContextIn Elm there is no question where it s in the model Model Event ChangesIn Elm you do not need to decide “where UI state lives because…all data lives in the Model Instead you need to decide how to change that data For simple applications it s much like you d do in Redux create a Message containing the new data and write code to change your model based on that message type Msg ToggleOnlyInStock BoolNow that you have your message you ll dispatch it when the user clicks the checkbox label input type checkbox onClick ToggleOnlyInStock not model onlyInStock text Only show products in stock Lastly change the data based on the message update msg model ToggleOnlyInStock toggle gt model onlyInStock toggle Top Development ReactUsing create react app you ll run npm start and your changes compile errors will be reflected quickly in the open browser window For a production build run npm run build ElmUsing elm live you ll run elm live and your changes compile errors will be reflected quickly in the open browser window For a production build run elm make with the optimize flag It s recommended you additionally utilize uglifyjs first with compress then again with mangle or some other compressor mangler library Top Testing ReactUsing create react app you ll run npm test which uses Jest internally If you are dealing with a lot of data on the UI or using TypeScript use JSVerify for property tests For end to end tests Cypress is a great choice ElmFor Elm unit tests often do not provide value given the compiler s correctness They re better expressed using end to end tests and those are more likely to expose your race conditions If you are dealing with a lot of data on the UI use elm test for property tests While normally for unit tests it has fuzzers and shrinkers built in For end to end tests Cypress is a great choice Top Routing ReactWhile there are a variety of choices react router is one many settle on function Home return lt h gt Home lt h gt function About return lt h gt About lt h gt function Users return lt h gt Users lt h gt function App return lt Router gt lt div gt lt nav gt lt ul gt lt li gt lt Link to gt Home lt Link gt lt li gt lt li gt lt Link to about gt About lt Link gt lt li gt lt li gt lt Link to users gt Users lt Link gt lt li gt lt ul gt lt nav gt lt div gt lt Router gt ElmElm has routing built in using the Browser library home h text Home about h text About users h text Users app div nav ul li a href home text Home li a href about text About li a href users text Users Top Error Boundaries ReactIn React you ll build a component or set of components to wrap common error areas so in case a volatile part of the UI throws you can handle it gracefully in the UI First create a basic wrapper component class ErrorBoundary extends React Component constructor props super props this state hasError false static getDerivedStateFromError error Update state so the next render will show the fallback UI return hasError true componentDidCatch error errorInfo You can also log the error to an error reporting service logErrorToMyService error errorInfo render if this state hasError You can render any custom fallback UI return lt h gt Something went wrong lt h gt return this props children Once you ve got your component with logging and a fallback UI you just wrap the dangerous components lt ErrorBoundary gt lt MyWidget gt lt ErrorBoundary gt ElmElm does not have runtime errors caveat port dangers in section down below The compiler will ensure that all possible errors are handled This means you either model those error states in your model ignore them with blank strings or design different UI s for those states Data not there You must handle it case dataMaybe of Just data gt addProduct data Nothing gt Your UI or data must compensate somehow here For now we just return all the products unchanged model productsHTTP operation you need to work fail You must handle it case result of Error err gt model result ProductSaveFailed err Ok data gt mdoel result ProductSaveSuccess data in UIcase result of ProductSaveFailed err gt errorViewAndRetry err ProductSaveSuccess gt goToProductViewTop HTTP Reactclass Weather extends React Component constructor
