Interview of @matheusml about #redux zero, a light state management solution for #reactjs

  • Redux Zero is a library which offers a simple way to handle state in modern applications.
  • With Redux Zero your component can focus 100% on the UI and just call the actions to update the state: – – Last but not least, plug the whole thing in your index file: – – Redux is great, but in some cases, it’s way too much.
  • With Redux Zero you just have a store and some actions.
  • One of our developers here at Concrete, Miguel Albernaz, was using this gist as a state management solution instead of Redux.
  • Redux Zero is one of the lightest state management solutions I’ve seen so far.

Although using Redux is straight-forward once you understand the approach and its nuances, after a while it gets repetitive. It’s easy to end up with a lot of “boilerplate” code that wires all the logic together. For this reason, multiple solutions addressing the issue have appeared.

CSS Modules with React: The Complete Guide – YoungInnovations’ Blog

CSS Modules with #ReactJS: The Complete Guide

  • css$/, use: [ { loader: ‘style-loader’, }, { loader: ‘css-loader’, options: { sourceMap: true, modules: true, localIdentName: ‘[local]___[hash:base64:5]’ } } ],}]CSS module makes CSS classes local for every component declared within by adding hashes in class names which are unique to each component, thus preventing CSS classes from one component overriding or conflicting with CSS in other components.Here is a simple example:panel.jsimport React from “react”;import style from “.
  • panelBody { padding: 15px;}Here classes panel and panelDefault are specific to Panel component and global class container comes from bootstrap applicable to whole site.An interesting thing to notice while writing multiple classes is that, if were to define class in html structure and do not define that class in CSS file, the genereated HTML will literally have undefined class.
  • panelBody { padding: 15px;}The generated HTML will be:div class=”undefined panelDefault___3JNN6″ div class=”panelBody___3OqQA”A Basic Panel/div/divSharing variables between CSS and JSOne of the things that excites me about CSS modules is ability to export variables from CSS file for use in JS file.
  • And there is a little extra step to get this working.With CSS modules, any CSS file a component is importing is local to the component as we are instructing webpack to map our CSS class names to unique hash based identifiers.A simple approach can be: define all locally scoped CSS along with each component js file and define global CSS in a separate direactory.All the CSS files inside app directory are locally scoped.locally coped css filesAnd CSS files inside styles directory can be global to whole site.To get this approach working, we have to add a simple configuration in our webpack config file.rules: [{ test: /\.
  • :)CSS module does not affect element and attribute selectorsWith CSS modules, class names are locally scoped to component in which it is defined, however, html element and attribute selectors are untouched.panel.jsdiv class=”panelDefault” div class=”panelBody” a color: salmon;}a{ text-decoration: none;}Here, above styles are global and applied across entire project.

In the developer community today, we are seeing new design patterns, libraries and frameworks trying to make front end systems even better. Web components are becoming de-facto in developing front…

Intro To Web Components: What They Are & How They Work

Intro to web components: What they are & how they work  #webcomponents #polymer #reactjs

  • A web component is a DOM element created through reusable code.
  • The idea behind web components is to create dynamic interface elements without writing custom JavaScript code or building your own libraries.
  • If you skim the Web Components intro guide it explains that components are built on four unique W3C technologies:

    Each of these features are separate and have their own specs on the W3C website.

  • If you do use Polymer alongside web component polyfills you can get large browser support for all four W3C technologies.
  • However if you’re willing to learn Polymer and dive into polyfills you can actually get web components running in all major browsers.

Reusable code is the bedrock of modern web design. With every frontend framework and Sass library out there you can find solutions to any problem.

Use Vue.js to create custom web components – Vue.js Tips

  • See browser support for Web Components on are-we-componentized-yet or caniuse.com

    But, with a bit of JS magic you can now turn your Vue.js component into web components, enabling you to use it in any web application, even using React, Angular or is a library written by @karol-f that allows you to use a Vue.js component as a custom element.

  • Once you register the custom element, you can insert its tag into standard HTML, SPA’s, React, Angular or Vue.js projects.
  • js file embedding Vue itself, the lib and your Vue.js components, registered to be used as custom elements.
  • Registering a custom element is done by using

    Note that is called when the element is inserted

    Also, the component’s tag has to meet a few requirements :

    More details in the W3C specs

    The custom element’s markup can be embedded in a tag inside the DOM.

  • I thought it would confuse developers that focus on porting their Vue.js components to custom elements.

Include Vue.js components in any HTML/JS application

Differences between AngularJS, VueJS and ReactJS – hello JS

Differences between #AngularJS, #VueJS and #ReactJS:

  • Another common question regarding ReactJS is whether it is necessary to learn Flux to learn ReactJS .
  • Unlike AngularJS , ReactJS is not a framework, it’s a library.
  • The prospect is that a lot of companies will still use AngularJS for quite a while.
  • It is entirely possible to write an application in ReactJS without the use of Flux and Redux .
  • The Facebook team with ReactJS solved these problems through the Virtual DOM – object that maps the whole tree of the DOM .

AngularJS is one of the most famous framework out there, gaining a lot of momentum lately. Some reasons for its popularity are: community engagement, open-source, the interest of the google team, etc…
