A React Navbar Component by Dan on CodePen

A simple, responsive #Navbar using #ReactJS:  @CodePen #Coding

  • I’m going to give it a name of NavComponent because that just makes way too much sense, and inside the render function, toss in an empty (for now) set of tags to wrap around everything else that will go in there: – – And underneath all that I’m going to…
  • This will give my a “hamburger” icon (courtesy of Font Awesome) for smaller screens that need a drop down menu.
  • Since our drop-down menu is contained in the “narrowLinks” className, we’re going to target that in our function: – – And then tell our function to toggle the drop-down based on its current CSS display value: – – And to make the new function work, we need to give our…
  • I obviously don’t want to see both sets of links all the time, and since we’re using mobile-first design, we’re going to set our “navWide” links to hidden: – – And we’re also going to stick our hamburger icon and drop-down links on the left side of the screen, just…
  • And finally a media query to switch between our mobile drop-down menu and our larger screen mode with just a row of our links: – – For a working example, click here.

I use React a lot, and I use navbars a lot, so this was just an obvious one for me. This is nothing extravagant. I’m not using React Router in this example, just some tags. But it is responsive, so that’s fun.

The Pros and Cons of ReactJS for your Online Business

The Pros and Cons of ReactJS for your #OnlineBusiness via @janlgordon

  • With React, it is possible for webmasters and online business owners to develop large web-based applications that change data while reloading pages.
  • Webmasters can also use React together with other forms of frameworks or JavaScript libraries like Angular in MVC.
  • It makes it possible to reuse components that didn’t produce changes, and this makes programming more comfortable and precise for online business owners.
  • The great news for webmasters is that Google might still find the React component when just the client-side is rendered.
  • ReactJS is a great framework for online business.

This isn’t quite a ReactJS guide for the layman. But it is a useful for business owners, if only to glean enough to know how to talk with your techie

Vue vs React: Battle of the Javascript Frameworks

  • I’ve created two nearly identical sample applications, one in Vue and one in React, if you’d like to give either framework a shot in the context of the samples in this article.
  • The biggest difference is that React popularized a Virtual DOM (we’ll get into this later) and created a new syntax called JSX that allows developers to write HTML in JavaScript.
  • Unlike earlier JavaScript frameworks that had ‘batteries included,’ both React and Vue are fairly barebones with functionality like routing and state management handled by separate frameworks.
  • Both React and Vue are focused solely on the UI layer, and leave functionality such as routing and state handling to companion frameworks.
  • In Vue there’s no need to call a state management function like , as the data parameter on the Vue object acts as the holder for application data.

React vs Vue.js. Are you in the market for a shiny new JavaScript UI framework? Find out the main similarities & differences between these two popular ones.

Protected routes and authentication with React Router v4

Protected routes and authentication with React Router v4  #ReactJS

  • In this post we’ll break down the “Redirects (Auth)” example on the React Router documentation to learn how to create authenticated routes (routes that only certain users can access based on their authentication status) using React Router.
  • It would be nice if, just like React Router gives us a component, they also gave us a component which would render the only if the user was authenticated.
  • So now what we’re doing is when the user authenticates, we change to true which causes a re-render and then renders the component taking the user to the route.
  • First, inside of our component when we redirect the user for not being authenticated, we’ll need to pass along the current route they’re trying to visit so we can come back to it after they authenticate.
  • Now we need to modify our component so that if the user was redirected there from a previous route, once they authenticate, they’re taken back to that original route.

Protected routes are an important part of any web application. In this post we’ll break down the “Redirects (Auth)” example on the React Router documentation to learn how to create authenticated routes (routes that only certain users can access based on their authentication status) using React Router.

Creating an Accessible React Website

Creating an Accessible #ReactJS Website:  via @dagda1 #JavaScript

  • The problem is that a newly server rendered page works great with a screen reader but when you change routes in an SPA, the screen reader does not know that there is new content.
  • With this higher order component in place, I can now add the correct labelling to any component such as the component previously described: – – The higher order component above takes care of displaying an error below each invalid field but a screen reader will not automatically pick this up…
  • Below is an exmple of such a validaion summary from gov.uk that I based our validation summary on: – – At first glance this is complete overkill for 2 fields but in the context of a screen reader, this is a great practice.
  • In the event of an error, focus is placed on the element in the component and a link is created for each validation error.
  • Below is a help container that expands and contracts when a link is clicked: – – A combination of , and are used to correctly instruct the screen reader that new content is toggled between visible and invisible states.

I’ve recently been working on an online application form in the form of a multistep wizard that had strict accessibility requirements. I’ …

React Digest #122 for November 20, 2017

  • How Redux Can Make You a Better Developer When React came out I was really amazed with its easiness of use and learning curve.
  • When I first started learning React I wasn’t aware of the fact that React is just a library and not a fully fledged framework.
  • Other frameworks would give you solutions and architecture out of the box which is not the case with React lib.
  • Getting from Redux to a state machine This article is about Stent – a Redux-liked library that creates and manages state machines.
  • In this post we’ll break down the “Redirects (Auth)” example on the React Router documentation to learn how to create authenticated routes (routes that only certain users can access based on their authentication status) using React Router.

When React came out I was really amazed with its easiness of use and learning curve. When I first started learning React I wasn’t aware of the fact that React is just a library and not a fully fledged framework. I wasn’t aware that I would need to make all decisions about architecture and what exactly I would need to use in order to solve some common tasks. Other frameworks would give you solutions and architecture out of the box which is not the case with React lib. Yes, someone might say that I was naive and dumb but that naivety and my will to learn new things pushed me forward and made me a better developer and decision maker.
