React’s ⚛️ new Context API – DailyJS – Medium

React’s ⚛️ new Context API   #reactjs

  • 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 – ) -…

It’s way more ergonomic, it’s no longer “experimental,” and it’s now a first-class API! OH, AND IT USES A RENDER PROP! NOTE: This is a cross-post from my newsletter. I publish each email to my blog…

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…

From React To Preact In Seconds – Devcenter

“From React To Preact In Seconds” by @codekayy  #React #reactjs #javascript #coding

  • From React To Preact In SecondsSo I decided to try out Preact after I heard it mentioned in an event that I attended earlier this year.
  • So I added the configuration to my webpack config – resolve: { – ‘alias’: { – ‘react’: ‘preact-compat’, – ‘react-dom’: ‘preact-compat’, – ‘react-addons-test-utils’: ‘preact-test-utils’, – ‘preact-css-transition-group’ – } – }Then I installed the modules by running – $ npm install -save preact preact-compat preact-test-utils version of my react module is…
  • xI aliased react-addons-test-utils and because I’m using the modules in my app.ResultsThe size of my app before changing to preact is shown below – When using reactI got the result below after changing to preact – When using preactGotchasWhen children is not supplied to a component, preact returns an empty array while…
  • You may lose some capabilities of React but not likely as I’ve not lost any.

What I learned making my first open source React component

  • A folder for your code, a folder for your demo app (plus dev server and hot loading, yay\o/), a folder that you should use and I didn’t, some build stuff for shipping… – – Basically, it gives you everything you need so you can focus on your component and don’t…
  • You need a demo page so you can show off your component in action.
  • react-lazyload-fadein, for example, has a demo page that shows off different ways you can use it.
  • People will find out about your component in different ways.
  • Especially if someone could figure out how to slurp in the README file and make that demo page for you 🤔 – – The React community is a bit silly and loves to invent new patterns to bicker about.
