#Reactjs #javascript

  • Well, Reacto is a suggestion to the react community.
  • You can also get suggestions from npm registry right from Reacto.
  • Start creating new class-based react components now, and see how it looks anytime you’ll edit the file.
  • Today, I really hope that I can give something back to all of you, so that new developers start programming with the right tools, for free.
  • If you have any suggestions or feedback, feel free to comment below or open a new issue on github using “feedback” and “idea” labels.

It all started with a need for a software, free, that would provide everything for react development. I started working on this personal project two months ago and it is with an extreme joy that I am…

Snapshot Tests in React Using Jest

  • Today we’re talking about snapshot tests using Jest.
  • When writing snapshot tests using jest, you should basically just follow the next template: – – You use to create a component with desired props, transform it to JSON and then check if it matches a snapshot.
  • Here’s a more concrete example – let’s say we have a dummy component called , for which we want to write a snapshot test: – – For our Input component, it can look something like this: – – To run the test, you just need to type command in terminal….
  • Output snapshot file will be created, and when running the test next time, jest will compare that output snapshot file to our updated component.
  • Keep in mind that all of these output snapshot files should be committed alongside the modules they are covering and their tests, as they are part of the test.

Build a Server-rendered ReactJS Application with Next.js from @tgrecojs on @eggheadio

Build a Server-rendered ReactJS Application with Next.js - #react course by @tgrecojs

  • In this course we we’ll see just how quickly next.js makes the process of building server-rendered ReactJS applications by creating and deploying an application that loads blog posts from the Google Blogger API.
  • Along the way we’ll learn about many of the amazing features Next.js provides for us out of the box, such as route prefetching and code-splitting, thus allowing us to spend more time developing and virtually no time setting up our environment.
  • Additionally, we’ll learn about the core concepts behind the framework and see how we can leverage them to create dynamic routes and integrate Material-UI on the server.
  • We won’t have to worry about using any specific architecture to handle state, instead we will just pass our data as ReactJS using Next.js’ lifecycle hook.
  • Throughout this course we will see why Next.js has gained such an amazing reputation as a “minimalist framework” by supplying users with “pretty” error messages.

Choosing Between React and Vue For WordPress Development

Choosing Between #ReactJS and #VueJS For WordPress Development -

  • In React, component state is mutated using the function setState(), while in Vue, you just change the variable value directly or you use v-model directive in an HTML template and it’s all magical.
  • Any mildly complex Vue or React app needs state management — using Redux, V\uex or similar — for app state and that involves state update function.
  • When creating React or Vue components this way, you have to write your own change handlers to modify state.
  • Vue’s data model is inspired by React and other frameworks based on observables.
  • In the React world create-react-app is a CLI tool, like Vue CLI for scaffolding apps.

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.

React Tutorial: A Comprehensive Guide to learning React.js in 2018

  • These components are defined either in pure JavaScript or they can be defined in what the React team calls “JSX”.
  • The reason the React team went with this approach is because, since the virtual DOM is a JavaScript representation of the actual DOM, React can keep track of the difference between the current virtual DOM(computed after some data changes), with the previous virtual DOM (computed befores some data changes).
  • In more layman’s terms, because manipulating the actual DOM is slow, React is able to minimize manipulations to the actual DOM by keeping track of a virtual DOM and only updating the real DOM when necessary and with only the necessary changes.
  • The process looks something like this, – – Some user event which changes the state of your app → Re-render virtual DOM -> Diff previous virtual DOM with new virtual DOM -> Only update real DOM with necessary changes.
  • Signal to notify our app some data has changed→ Re-render virtual DOM -> Diff previous virtual DOM with new virtual DOM -> Only update real DOM with necessary changes.

Grid system based on styled-components and flexbox for #Reactjs

  • Set of React components that implement but with .
  • Furthermore, it allows to customize grid configuration like gutter width… – – Highly inspired by the excellent which the API is nearly the same than this module.
  • Use the configuration for fixed width value.
  • The grid use same defaults than .
  • You can customize values using component from styled-components.

GitHub is where people build software. More than 27 million people use GitHub to discover, fork, and contribute to over 80 million projects.
