9 React Tools To Master Your Component Workflow – Bits and Pieces

  • Basically, this project lets you define styled-components that posses their own encapsulated styles so that styling becomes an actual part of your components while avoiding the use of CSS classes as a mediator layer.
  • This project is growing in popularity to become the go-to choice for styling React components, and is defiantly worth checking out for your next app.
  • This project “scans” your app for React components and lets you render components with different states and props while mocking external dependencies, so you can see your app’s state in real-time.
  • React Sketch.appFor the UI designer / dev among you, React-sketchapp is Airbnb’s open source project built for design system which enables the rendering of React components using Sketch.
  • From sharing components between apps with Bit to styling with styled-components or using storybook to render and play with components in isolation, and all the way to less familiar projects like UiZoo and others, the React ecosystem is growing rapidly to help you build an amazing UI.

Best 9 React component tools and libraries that can make all the difference for mastering your work with React components for developing a beautiful UI for your React application. Check out the list.

Find my upcoming workshops: – Advanced React Component Patterns – The Beginner’s Guide to…

  • Making React components that can be used in multiple places is not hard.
  • Without the right patterns, you can find yourself with a highly complex component that requires a lot of configuration props and way too many if statements.
  • With this course, you’ll not only learn great patterns you can use, but also the strengths and weaknesses of each so you know which to reach for to provide your components the flexibility and power you need.
  • I have contributed to and published some of the most successful React components in the React ecosystem.
  • Through that experience, I’ve learned and taught patterns that enhnace flexibilty, usefulness, and simplicity.

How and Why to Bind a Callback Function in React Components

How and Why to Bind a Callback Function in #reactjs Components  #javascript

  • If you ask yourself, why you even have to bind callback functions and when you actually have to do this, this article is for you: Today we’re going to learn about binding the  keyword in React components.
  • Avoid binding by using the public class fields syntax, or bind your callbacks inside the constructor.
  • Another way to bind  is to do so in your parent component’s constructor by calling for your callback function: – – That’s it!
  • Instead of binding the callback function in your constructor, you can do so while passing it through a prop: – – Note: Whenever your component is re-rendered, returns a new function and passes it down your component tree.
  • Instead of using the public class field syntax, you could directly pass an arrow function down your props: – – Note: Like in the previous example, this creates a new callback each time your component is re-rendered and may cause unnecessary re-rendering of your component tree.

Why do we need to bind ‘this’? What’s the best way to bind a callback function in React components? Read about the why and how in this article and never worry about binding callbacks again!

@ZackArgyle 1. Start with plain React. 2. Lift state as needed. 3. Still feeling pain? Use Redux/Context/etc.

  • Currently, both components independently keep their values in the local state: – – However, we want these two inputs to be in sync with each other.
  • Since the props of both components are coming from the same parent component, the two inputs will always be in sync.
  • It will handle the change by modifying its own local state, thus re-rendering both inputs with the new values.
  • For example, if we enter 37 into the Celsius input, the state of the component will be: – – If we later edit the Fahrenheit field to be 212, the state of the will be: – – We could have stored the value of both inputs but it turns out…
  • The inputs stay in sync because their values are computed from the same state: – – Try it on CodePen.

Often, several components need to reflect the same changing data. We recommend lifting the shared state up to their closest common ancestor. Let’s see how this works in action.

Why build your forms with Redux Form – DailyJS – Medium

  • Why build your forms with Redux FormWhen I usually create forms for my React/Redux applications I tend to keep the value of the inputs on the application state, with little to no editing, (because my forms are usually simple), I never stopped to realize what that means.
  • It also receives an event handler that will update the state when the user interacts with it.It means that when the user types the letter “J” on the input, what is visible is not the same “J”, it may be an identical “J” that comes from the state, or whatever…
  • It keeps track of all common application form state such as:The fields that are in the form;The values of each field;The focused field;If the field values are valid;The fields that the user have interacted with;If the form is being submitted;If is happening any asynchronous validation.Let’s take a look at a…
  • It will also hand us the handleSubmit function, which will take care of the submission behavior.The Field component takes our input component as its props and acts as a container, bringing the application state to the input component and binding the event handlers to update the state in store.Look at…
  • Look that the default value of the input is defined when the high-order component reduxForm is called and comes to the input within the prop input and not from the react’s prop defaultValue, this way we guarantee that our form values are all represented in the application state.In summary, having…

Making ReactJS Realtime With Websockets

Making #ReactJS Realtime With #Websockets

  • Installation – Now, install create-react-app and also scaffold a new React app with the following commands: – npm install -g create-react-app – – create-react-app react-pusher – – Once all the necessary files are installed, change directory into react-“pusher and start the application with: – npm start – – By now,…
  • There are number of dependencies required for the application server, so let’s install them immediately: – npm install –save axios body-parser cors express pusher pusher-js – – To configure the entry point of the application, create a file called server.js and paste the code below into it: – const Pusher…
  • /ChatBox.css’; – export default ({ text, username, handleTextChange }) = ( – div – div className=”row” – div className=”col-xs-12″ – div className=”chat” – div className=”col-xs-5 col-xs-offset-3″ – input – type=”text” – value={text} – placeholder=”chat here…” – className=”form-control” – onChange={handleTextChange} – onKeyDown={handleTextChange} – / – /div – div className=”clearfix”/div – /div…

Why You Should Consider ReactJS for Your Web Application?

Here's Why You Should Consider #ReactJS for Your #Web Application.

  • Yes, we are talking about ReactJS – the JavaScript library which is the hot favorite of developers and is climbing the popularity charts every day.
  • Managing system updates is very easy with ReactJS because every change does not necessarily affect each component in the system.
  • Developers using ReactJS have free access to a variety of useful applications and tools from the community at large.
  • Apart from these, there are numerous other examples such as Uber, Salesforce, KISSmetrics, Tesla, Scribd, Reddit, Periscope and many more which have leveraged the power of ReactJS to build world-class interactive web applications.
  • If you are looking to develop SEO-friendly, interactive web applications with great UI and expect your application to handle heavy traffic, it’s time to migrate to ReactJS.

According to the 2016 StackOverflow developer survey, React.Js’s popularity had recently increased by over 300%.What is making ReactJS so popular? Let’s take a look why you should consider ReactJS for your web application?
