Evolving Patterns in React

  • A good way of bypassing this is to use props destructuring together with JSX spread , as you can see here: – – So now, you can change the props needed for and be sure that those props are not referenced in multiple components.
  • If you are using Redux, you will recognize that the function is a HOC — takes your component and adds a bunch of props to it.
  • Let’s implement a basic HOC that can add props to existing components.
  • Each HOC will introduce an additional React Component in your DOM/vDOM structure.
  • Render props can be used in situations where you need some reusable logic inside the component and you don’t want to wrap your component in a HOC.

Let’s take a closer look at some of the patterns that are emerging in the React ecosystem. These patterns improve readability,…

Introduction To Redux

  • Before you start reading this article, I will suggest you read the first part of this Redux series to have a basic understanding of Redux features and functionalities, – – The events happening in the application are called actions.
  • There are 3 core benefits to having immutable state – – To change the store, you dispatch an action that is ultimately handled by a reducer.
  • A reducer is a function that takes state and an action and returns a new state.
  • When the store is created, Redux calls the reducers and uses their return values as an initial state.
  • In this article, we saw what actions, store, and reducers are in Redux.

In this article, we will see what Actions, Store and Reducers are,.

Infinite scroll techniques in React – LogRocket

Infinite scroll techniques in #reactjs – LogRocket  #javascript

  • Infinite scrolling technically requires adding a scroll event listener to the window object or a certain div.
  • Implementing from the ground upAs mentioned earlier, infinite scroll is about attaching event listeners to DOM elements while watching for when the scrollbar hits the bottom of the div.
  • Look at the render function of this Component below: – Say you want to load more li items into the ul tag each time the div with the class App gets to the end of the div, how do you tackle this problem?
  • Here is what the final component should look like: – Using an infinite scroll libraryWhile the first method showed how relatively easy it is to implement infinite scroll in React applications, you might not be so content to implement event listeners yourself.
  • Instead, there is hasMoreItems which is used to tell the Infinite scroll component to detach the event listenerAn alteration to the loadMore function, which sets the hasMoreItems state to false once the items his 200ConclusionAnd there you have it, two different methods that allow you to implement infinite scroll in…

Infinite scroll techniques In React – LogRocket

  • This determines when the scroll has reached the bottom of the div and then performs actions accordingly.In this tutorial, I will explain two methods of implementing infinite scroll in React:The first method describes implementing everything from the ground upThe second method uses an already available infinite scroll library/componentA basic understanding…
  • The items hold the number of items available to be shown as li tags while the loading state will show when the infinite loader is fetching more items.Next, create a function that renders all items:This function loops through the number of items present and create a li tag showing the…
  • Define the ComponentWillMount method:In the method above, a scroll listener was added to the myscroll ref which references the div being targeted.
  • In your application, you probably want to make a fetch or axios call to your server and then change state.But no matter your use case, the concept remains the same.Here is what the final component should look like:Using an infinite scroll libraryWhile the first method showed how relatively easy it is…
  • Instead, there is hasMoreItems which is used to tell the Infinite scroll component to detach the event listenerAn alteration to the loadMore function, which sets the hasMoreItems state to false once the items his 200ConclusionAnd there you have it, two different methods that allow you to implement infinite scroll in…

React Lifecycle Events for Sencha Devs

  • A big plus is that, like ExtJS, React’s components have some simple lifecycle events.
  • Lucky for us, we can use our knowledge of ExtJS lifecycle events to help us understand React’s and that gives us a nice place to start learning.
  • If you set the component state here you will still only get the initial render and not an extra one.
  • As you’d expect, this method is called just before our component is removed from the DOM.
  • I hope you found this quick ExtJS React event comparison helpful.

Welcome Sencha developer! So, you want to learn React. Maybe you’re wondering where to start? Well, getting a basic understanding of React’s components is a great place to start. A big plus is that, like ExtJS, React’s components have some simple lifecycle events. Lucky for us, we can use our knowledge of ExtJS lifecycle events to help us understand React’s and that gives us a nice place to start learning. So, let’s take a quick look at them and see if we can understand when to use each one.

Building Small Apps with React

Building Small Apps with React  #reactjs #javascript #AppDev #programming #coding

  • Enter Cerebro: a cross platform extensible electron app that provides the perfect tools to build something small but useful with React.
  • Now we can do a bit of setup:

    Our plugin, cerebro-weather, will allow users to search for a city and then show a concise preview of the weather conditions of that city if it exists.

  • Create an file with the following:

    This function makes an initial request to the API to search for a given city.

  • We convert this response to JSON and retrieve the weather details for the first location with the location’s , which is its unique identifier and the only actual way to retrieve weather data from the API.
  • This gets the weather data with our API function, and displays the first consolidated weather report.

Guide developers that newly learned React to build a small but useful app with Cerebro
