#ReactJS’s ⚛️ new Context #API:  by @kentcdodds #JavaScript

  • Here’s the simplest useful example I can come up with: – Here’s an even simpler version so you don’t have to open the codesandbox: – const ThemeContext = ThemeProvider extends React.Component { – state = {theme: ‘light’} – render() { – return ( – ThemeContext.Provider value={this.state.theme} – {this.props.children} – /ThemeContext.Provider…
  • , but if that’s not your jam, you could easily implement a Higher Order Component or something else using the context API (which is why it’s the best).
  • The React team will remove the warning about context being an experimental feature because it’s now a “first-class featureâ€� of the framework.
  • Here’s an example: – const ThemeContext = ThemeProvider extends React.Component {/* code */} – const ThemeConsumer = ThemeContext.Consumer – const LanguageContext = LanguageProvider extends React.Component {/* code */} – const LanguageConsumer = AppProviders({children}) { – return ( – LanguageProvider – ThemeProvider – {children} – /ThemeProvider – /LanguageProvider – ) -…

Building an eCommerce Scraper with Node.js and React.js

  • It allows the user to type in a specific product name, to crawl multiple e-commerce sites and asynchronously return useful results to the user.
  • UI and ArchitectureBuilding the front endTo make it short, the front end is really small (only two pages: one for the search box and another one for the results).
  • I moved everything from ‘search term’ to ‘search results items’ into Redux’s state, thus making the code structure cleaner and nicer.
  • Some other problematic factors include: – Not having pre-stored information that could be useful to make predictions.Each result item consisting only of the following data: title, price, URL and thumbnail.My conclusion was to use a weighted ranking algorithm.
  • In a more complete implementation, that data could be useful for some sort of Machine Learning algorithm to predict the most useful way to rank results.

This is a quick story about how I created a simple but end-to-end e-commerce scraping web application called “crawl-io”. The goal behind this article is to provide an example of an implementation so…

For #reactjs enthusiasts, I found this pretty cool!

  • My love for streaming entertainment dates back to the early days of RealPlayer and the misery of a million codecs.
  • That lead me to think:  is there a good open source component for embedding videos from popular video providers?
  • Let’s check out ReactPlayer, a very simple but useful streaming video player component for ReactJS!
  • Using the ReactPlayer component is really simple: – – ReactPlayer provides a number of options for both general and service-specific playback, also providing a number of event callbacks and even multi-source playback options.
  • ReactPlayer is an awesome utility for embedding popular media sources in your own site.

React’s safe Context API – codeburst

  • It’s purpose is to aid with that specific scenario ğŸ�‰ – But in older versions of React, you should not use it âš ï¸� – If you want your application to be stable, don’t use context.
  • You can read about the drawbacks of the current Context API here 📖 – The good news is there’s a new Context API in React@16.3! And it’s much better 🙌 – So, if you hadn’t heard of or used the Context API until now, there’s no need for FOMO 😅…
  • Here’s a demo of a theme toggle using the new safe version that’s currently obtainable in React@16.3ğŸ‘� – When would I need the Context API?It’s hard to think of an array of scenarios in which you’d need to use the Context API.
  • In many cases it will probably suffice ğŸ‘� – How might we handle it with the Context API?I’m not going to touch on the current release version of the Context API as the docs deter us from using it âš ï¸� – Instead we can take a look at how a solution…
  • Updating it might look like this – The consumer will pass a single render prop which is the current value for the Context ğŸ‘� – Much like Providers, you can have many Consumers within the component tree.

Ever needed to pass a prop down through many levels of the component tree? Did you do it manually? It’s not ideal is it? Did it have to pass through components where it looked out of place? The…

React’s ⚛️ new Context API

  • The provider component puts the data into context, and the Higher Order Component pulls the data out of context.
  • The first pull request to that repository is from Andrew Clark (react core team member) and it’s called “New version of context”.

  • The React team will remove the warning about context being an experimental feature because it’s now a “first-class feature” of the framework.
  • One question that I’ve seen a lot about the new context API (or the render prop pattern in general) is how to compose providers and consumers together.

Why is It Better to Use ReactJS over Others? – Aglowid It Solutions

Why is It Better to Use ReactJS over Others? 



#reactjs #ReactNative #React

  • If you hire ReactJS developer, they will not only create ultra-fast user interfaces but also with a simple Chrome extension, they can debug the codes.
  • Another advantage of using ReactJS development services is JSX.
  • Simply, JSX lets developers mix JavaScript and  HTML; with JSXTransformers, ReactJS turns all HTML tags into functions.
  • React-Native, also developed by Facebook in 2015 follows the footsteps of ReactJS to develop mobile applications for iOS, Android, and other platforms.
  • ReactJS with its Virtual DOM renders web pages on the server itself; and then sends it to the browser thereby making it easier for search engines.

React or ReactJS developed by Facebook back in 2013 is a JavaScript library that creates web interfaces which can change without a user reloading the page. If you hire ReactJS developer, they will not only create ultra-fast user interfaces but also with a simple Chrome extension, they can debug the codes. One of the prime…

Protected routes and Authentication with React and Node.js

Protected routes and Authentication with React and Node.js  #reactjs  #react #Nodejs

  • Front-end App ArchitectureI’m a huge fan of the React Boilerplate architecture so I created something similar to organize my code: – /src – └─── containers // React components associated with a Route – | └─── App // The entry point of the application – | └─── AuthPage // Component handling…
  • component={AuthPage} / – Route exact path=”/connect/:provider” component={ConnectPage} / – Route path=”” component={NotFoundPage} / – /Switch – /div – /Router – ); – } – } – – export default App;Creating the Authentication ViewsNow that all our routes are implemented we need the create our views.  –  The way we declared…
  • First of all, let’s create a forms.json file that will handle the creation of the form on each auth structure of the JSON will be like the following (you can see a customBootstrapClass key that is needed in the Input component): – { – “views”: { – “login”: [ -…
  • Here is the flow: – The user clicks on login with FacebookIt redirects him to another page so he can authorize the appOnce authorized, Facebook redirects the user to your app with a code in the URLSend this code to StrapiAt this point, we need to implement only one lifecycle…
  • catch(err = { – }); – } – – redirectUser = (path) = { – the Providers in the AuthPage – To do so, we need a SocialLinkcomponent like the following: – /** – * – * SocialLink – * – */ – – import React from ‘react’; – import…

So I started a side project to create a tiny boilerplate with nothing more than Create React App to implement the authentication flow with Strapi, a Node.js framework with an extensible admin panel…
