‘REACT.JS’ — WHERE AND WHY TO USE IT? @nodejs #NodeJS #webdev #javascript #reactjs @reactjs

  • One such example is when Code Academy adopted Facebook’s library, React JS to write JavaScript UIs , which lead to certain important discussion points regarding how React JS can be put to good use in case of larger and complex applications similar to Code Academy.What is React?Simply put, React is a UI library created at Facebook to cater the development of interactive and reusable UI components.
  • One of the USPs of React is that it can perform both on client side and rendered server side and also can work together.React is intended to make the overall process of building reusable, modular, user interface components intuitive and simple.
  • In place of the traditional approach of writing user interfaces, it treats every UI (User Interface) element as a contained state machine.Why use React for larger applications?React is very a lightweight and simple library which only deals with view layer.
  • You should think over the possible performance issues when you build a web application which has a higher user interaction and view updates.
  • React is expressively more SEO friendly than other JavaScript MVC frameworks since it is based on the virtual DOM.The Bottom LineReact is a powerful, lightweight, battle-tested library to build user interfaces with JavaScript.

The Web has gone far too long since HTML5 first came into the picture and people started observing JavaScript as a language which could be used for building complex apps. Most of the APIs have…

  • Design simple views for each state in your application, and React will efficiently update and render just the right components when your data changes.
  • SourceI.e React is the V (View) in MVC that is used to render views like HTML pages dynamically based on some state, which is often in the form of data.
  • React then updates the generated views whenever the original state changes.Declarative views make your code more predictable and easier to debug.The virtual representation of views in memoryFor the browser’s case, we write HTML using JavaScript in React relying on the power of JavaScript to generate HTML that depends on some data, rather than enhancing HTML to make it work with that data.
  • SourceBuild encapsulated components that manage their own state, then compose them to make complex UIs.SourceSince component logic is written in JavaScript instead of templates, you can easily pass rich data through your app and keep state out of the DOM.Learn Once, Write AnywhereYou can develop new features in React without rewriting existing code.React can also render on the server using Node and power mobile apps using React Native.In order to write your first react components you have to be familiers with some of the features react offers like How to:Write React componentsRender data to the pageCommunicate components i.e pass data from one component to anther ?

React is declarative, efficient, and extremely flexible. What’s more, it works with the libraries and frameworks that you already know like jQuery’s UI plugin. React was built to solve one problem…

Quick Basics of ReactJs, Redux & Redux-Saga ~ NT

Quick basics of #ReactJS, #Redux & Redux-Saga:  #JavaScript #frontend

  • JSX Converts xml data into objects:

    Gets converted to

    React uses Components, which is the root of React to display and provide data, we do it via:

    Functional based:

    Class based:

    Using to state to manipulate the html, react renders when either props changes or state changes.

  • There are good practices for component render, we shouldn’t be mutating objects in render, because the render method then keeps trigger further render cylces;

    Not the best way:

    // Not the best way
    class LoggingButton extends React.Component {
    handleClick() {
    console.log(‘this is:’, this);
    }

    render() {
    // This syntax ensures `this` is bound within handleClick
    // The arrow function always creates a new anonymous function
    // and hence a new function is passed as props hence the button
    // would be re-rendered even if it’s props actually wouldn’t change
    return (
    button onClick={(e) = this.handleClick(e)}
    Click me
    /button
    );
    }
    }

    The good way:

    Keys – it help React identify which items have changed, are added, or are removed (list of rendering):

    Controlled component: In HTML, form elements such as input, textarea, and select typically maintain their own state and update it based on user input.

  • UnControlled components: Some times we need to access the components data and might not have the state to check the data being used, and which case we can use ref to fetch the data
    Don’t Overuse Refs: lifting the shared state up to their closest common ancestor
    Important: There should be a single “source of truth” for any data that changes in a React application.
  • Three principles:

    Single source of truth
    State is read-only
    Changes are made with pure functions

    Basics:

    Actions: These are payloads of information that send data from your application to your store.

  • function todoApp(state = initialState, action) {
    switch (action.type) {
    case SET_VISIBILITY_FILTER:
    return Object.assign({}, state, {
    visibilityFilter: action.filter
    })
    case ADD_TODO:
    return Object.assign({}, state, {
    todos: [
    …state.todos,
    {
    text: action.text,
    completed: false
    }
    ]
    })
    default:
    return state
    }
    }

    Store: Once we have the actions and the reducers in place, the orchestration is done by Store by bringing them together using “createStore” from redux and hence we get methods like:

    getState of the application
    dispatch the action to the reducer — Mapped distpatch to props when using “connect”
    subscribe the listeners — Mapped state to props when using “connect”

    Combine the reducers once we split them using combineReducer.

How Does ReactJS Solve the Problem of Data Changing Over Time?

How Does #ReactJS Solve the Problem of Data Changing Over Time? | Concepta  #b2b #enterprise

  • React Native compiles to native app components so you can build your apps in native iOS or native Android.
  • React.js, as its name implies, responds to data changes instantly and renders the right components for a smooth user experience.
  • React creates composable user interfaces with reusable components that react to data changes.
  • Whenever the data changes, React calls a new render method.
  • One thing you can be sure of is that your apps will have to handle more data, from more sources and in tighter refresh cycles.
