海外TECH	DEV Community	Starting with React-Redux	https://dev.to/mohitm15/starting-with-react-redux-1dno	Starting with React ReduxHello everyone this is my first post on Dev to In this post I am trying to explain the use of Redux in ReactJS with an example Here I have taken some references from YouTube Channel CodeWithHarry and Google for information I will first explain to you the need for Redux and explain it with the code For reference you can check out Github to view the code anytime View Live Demo View on Github Why do we need Redux When a JavaScript Application grows big it becomes difficult to manage its state For example in the given architecture if I want to use the state defined in Child C of the Contact js in the Child B of the Home js then I had to do prop drilling where I have to pass the state as props over various components But Redux solves this problem by managing the application s state with the help of a single global object called Store This provides consistency to the application and makes testing easy Redux ArchitectureThe Architecture consists of components mainly Action Reducer Store and View And believe me they work in the same way as their name suggests Action is a plain object that describes the intention to cause change like adding or deleting a task in a To do List app Reducer is a function that determines changes to an application state Like in the To do List app action will trigger a change in the value of state task Array that the reducer will determine It returns the new state and tells the store how to do it Simply it uses the action it receives to determine the change Store projects all the state variables to the view which is the UI of the application Now let s make our hands dirty and start coding with an example to understand Redux more deeply I will tell you the concept and later you can start with your stuff to do with it Also I have added some tasks for deep understanding in the end Example Redux Boilerplate Here we try to create a webApp where we define the states in different components and perform onclick events from different components The states we define are the countValue and darkMode enabling If you directly want to see the whole code you can view it on Github View on Github Setting Up React AppCreate a folder in your desktop named redux boilerplate and open it in the VSCode Now open the terminal and create the react app npx create react app redux boilerplateNote You ll need to have Node gt and npm gt on your machine Now add the Bootstrap by using the CDN link of CSS here and script link here If you are new just simply copy the lt link gt and lt script gt from both the links and paste it to the public gt gt index html file at appropriate place ProTip To check bootstrap added successfully just simply paste the code to App js file and see red colored font import App css function App return lt gt lt h className text danger gt Hello World lt h gt lt gt export default App Creating NavBar and Shop ComponentCreate a folder components in src folder Now create a file Navbar js amp another file Shop js both in components folder NavBar jsimport React from react const Navbar gt return lt div gt lt nav className navbar navbar expand lg navbar dark bg dark gt lt div className container fluid gt lt a className navbar brand href gt Redux BoilerPlate lt a gt lt button className navbar toggler type button data bs toggle collapse data bs target navbarSupportedContent aria controls navbarSupportedContent aria expanded false aria label Toggle navigation gt lt span className navbar toggler icon gt lt span gt lt button gt lt div className collapse navbar collapse id navbarSupportedContent gt lt ul className navbar nav me auto mb mb lg gt lt li className nav item gt lt a className nav link active aria current page href gt Home lt a gt lt li gt lt li className nav item gt lt a className nav link href about gt About lt a gt lt li gt lt ul gt lt div gt lt div gt lt div className form check form switch mx gt lt input className form check input type checkbox id flexSwitchCheckDefault gt lt label className form check label text light htmlFor flexSwitchCheckDefault gt Darkmode lt label gt lt div gt lt div gt lt div gt lt button className btn btn info mx gt CountValue lt button gt lt div gt lt div gt lt nav gt lt div gt export default Navbar Shop jsimport React from react const Shop gt return lt gt lt div className container p gt lt div className alert alert success role alert gt lt h gt Redux BoilerPlate lt h gt lt div gt lt h className my gt Simple Starter template for redux store lt h gt lt div className container my gt lt h className display gt This is LightMode lt h gt lt div gt lt div className container d flex gt lt button className btn lg btn success mx gt lt button gt lt h className display gt You Count Value lt h gt lt button className btn lg btn danger mx gt lt button gt lt div gt lt div gt lt gt export default Shop Paste the above code in Navbar js amp Shop js respectively Add the components in App js usingimport Navbar from components Navbar import Shop from components Shop return lt gt lt Navbar gt lt div className container p gt lt Shop gt lt div gt lt gt This will show the navbar at top and Shop component on screen Installing ReduxTo install the redux just open a new tab in terminal and run npm i redux npm i react redux npm i redux thunkGet more info here Creating Action Creator and ReducersNow we ll create action creators and reducers function which will change the countValue and enable darkMode As discussed action creators create the action to change the state variable and reducer is a pure function that takes action amp the previous state of the application and returns the new state Action consists of type and payload to be supplied to Reducer function The type defines the action type and the payload defines the value to be substituted with the previous one To do this we will create a folder name state inside the src folder Inside the src folder we create two more folders action creatorsreducerNow we create index js file in action creators folder and write code for action creator We will create action here export const increaseCount countValue gt return dispatch gt dispatch type increase payload countValue Here increaseCount is a function that returns a function named dispatch which dispatches type amp payload Try to write action creators for decreaseCount enableDarkMode and enableLightMode in the same file You can compare your code with the full code of state action creators index js from here Now we make Reducers Reducers need not to be a single one for the different states we have different reducers Like here we ll create two reducers file named countReducer js and darkmodeReducer js inside reducer folder which will look after the countValue and darkMode state variables Let s create countReducer js to change the count value const reducer state action gt if action type increase return state action payload else if action type decrease return state action payload else return state export default reducer As you can see above it takes the state variable and action from the action creator as a parameter and returns the modified state with the help of the action payload Try to create darkModeReducer js by own first and compare your results from below const reducer state OFF action gt if action type darkmode state action payload else if action type lightmode state action payload return state export default reducer BonusSince for large complex applications we know that we require many reducers and handling them individually is a messy task So redux provides us combineReducers which combines all the reducer functions and export them as a single reducer function For this create a file index js in reducer folder and paste the below code import combineReducers from redux import countValueReducer from countReducer import darkmodeReducer from darkmodeReducer combinnig all the reducers hereconst reducer combineReducers countValue countValueReducer darkmode darkmodeReducer export default reducer Creating StoreTo recall a store is a global place where all the things defined is exposed to all the application Simply every part of the application gets access to the store Here we will create a file store js inside the state directory Use to code below for store js import applyMiddleware createStore from redux import thunk from redux thunk import reducer from reducer export const store createStore reducer applyMiddleware thunk You have seen many new things here let s understand them one by one createStore It takes the reducers preloaded state and enhancer function optional to create the store It returns an object that holds the complete state of your app applyMiddleware Returns a store enhancer that applies the given middleware redux thunk Helps to execute asynchronous functions Hurray store is created Now I want to give access of store to the overall application So we go to the file src index js main index js file and import the store here The file will look likeimport React from react import Provider from react redux import store from state store ReactDOM render lt Provider store store gt lt App gt lt Provider gt See complete file here Also we create a file index js inside state directory This will increase the accessbility of action creators as we export all the action creators from here to all the components like Navbar js export as actionCreators from action creators index Second Last StepAs far as now we have not added any function to the button and darkmode toggle but now we got access to the state variables through store we can use them to display their values on the UI To access the state we use useSelector hook In the navbar js file we import the hook first usingimport useSelector from react redux and then use it as const countValue useSelector state gt state countValue const darkmode useSelector state gt state darkmode And change the value of countValue from to countValue like this lt button className btn btn info mx gt CountValue countValue lt button gt So far we have use the countValue state we also need to use darkMode state in App js and Shop js App jsimport useSelector from react redux import App css import Navbar from components Navbar import Shop from components Shop function App const darkmode useSelector state gt state darkmode let darkmodeStyle backgroundColor ddd color whitesmoke return lt gt lt Navbar gt lt div className container p style darkmodeStyle gt lt Shop gt lt div gt lt gt export default App In shop js just simply import the useSelector hook like in Navbar js usingimport useSelector from react redux and then use it as inside Shop component const darkmode useSelector state gt state darkmode Last StepNow we have access to the variables that we use to bring the changes on view Here state values will be first changed by the user from the front end Then we need to generate those actions which triggers reducer functions and finally alter the values of the state on view To do this we use useDispatch hook which dispatches the action creators and bindActionCreators to bind all action creators Time to use them In Navbar js and Shop js import them asimport useSelector useDispatch from react redux import bindActionCreators from redux import actionCreators from state index And in Navbar js we use enableDarkMode action creator to dispatch const dispatch useDispatch to dispacth the action creator functions const enableDarkMode bindActionCreators actionCreators dispatch We will add this darkMode functionality to toggle button present in navbar like this lt input className form check input onClick gt darkmode OFF enableDarkMode ON enableDarkMode OFF type checkbox id flexSwitchCheckDefault gt And add the styling in the App js as const darkmode useSelector state gt state darkmode let darkmodeStyle if darkmode ON darkmodeStyle backgroundColor ddd color whitesmoke return lt gt Also change a div component in Shop js to switch the title on the main page from LightMode to DarkMode Shop js lt div className container my gt lt h className display gt This is darkmode ON DarkMode LightMode lt h gt lt div gt Now you will be able to change background color To use countValue action creator to dispatch we need to code in Shop js const dispatch useDispatch const balance useSelector state gt state countValue const increaseCount decreaseCount bindActionCreators actionCreators dispatch We will add this increaseCount decreaseCount functionality to and buttons present in screen like this lt div className container d flex gt lt button className btn lg btn success mx onClick gt increaseCount gt lt button gt lt h className display gt You Count Value balance lt h gt lt button className btn lg btn danger mx onClick gt decreaseCount gt lt button gt lt div gt Now you will be able to change the countValue For reference Complete Navbar js file is here Complete Shop js file is here Complete App js file is here ConclusionCheers you have build the basic template for redux Now you can come up with as many functionalities and components to the application You can take up some challenges by trying tasks like adding a login page displaying the profile page or categorizing the type of users Try to come up with your own ideas and send the PRs over here Thank you for your time Happy Coding ️	2021-11-21 14:45:55

海外TECH	DEV Community	Ruby 3	https://dev.to/shayanholakouee/ruby-3-1o2g	Ruby Ruby has been released This major new version has goals of improving performance concurrency and support for Typing The headline improvement is the performance with Yukihiro Matsumoto aka Matz the chief designer of Ruby saying that Ruby will be three times faster than Ruby Ruby has gained popularity because in addition to being fun to use it is useful because of its mix of different programming styles ーfunctional dynamic and object oriented Tests run using the Optcarrot benchmark which measures single thread performance based on NES s game emulation workload Ruby has shown the promised three times faster performance than Ruby The performance is achieved by Ruby when used in JIT mode This is new in Ruby and should provide performance improvements in limited workloads such as games AI and other applications where the majority of the time is spent in calling a few methods many times The developers say that while Ruby has significantly decreased the size of JIT ed code it is still not ready for optimizing workloads like Rails which often spend time on many methods and therefore suffer from i cache misses This will be exacerbated by JIT so the performance will actually be worse The developers say Ruby will offer further improvements on this issue Another area that has helped performance is the move to add better concurrency support The new release adds experimental support for Ractor as well as Async Fiber Ractor is an Actor model like concurrent abstraction that can provide a parallel execution feature without thread safety concerns This is achieved because ractors don t share normal objects communication between ractors is supported by exchanging messages The experimental nature of Ractor means the specification and implementation may be changed in the future Fiber Scheduler has also been introduced for intercepting blocking operations This allows for lightweight concurrency without changing existing code Other improvements add support for static typing The developers have created a “foundational type signature language called RBS which is used to describe the types of Ruby programs The idea is that RBS will support commonly seen patterns in Ruby programs and will allow developers to create advanced types including union types method overloading and generics It also supports duck typing with interface types Ruby ships with the rbs gem which allows parsing and processing type definitions written in RBS The Ruby team says type checkers including TypeProf and other tools supporting RBS will understand Ruby programs much better with RBS definitions	2021-11-21 14:07:41
