Getting Started With React Programming

Getting Started With #ReactProgramming by @KumarPraveen179 cc @CsharpCorner  #Reactjs

  • You should know the basic concepts of JavaScript like – – – Basically, it is a JavaScript library for building user interfaces.
  • We can say that it’s a new type of JS library, offering a new approach to build/update a View.
  • It creates a virtual DOM to track the changes when the application state is updated and uses the virtual DOM to update only those parts of a page which have been changed.
  • It was first deployed on Facebook’s Newsfeed in 2011 and after that, on – – Where To Use React – – As we discussed above, it’s a JavaScript library so, it is possible to use React everywhere where JavaScript code can be executed.
  • In the upcoming article, I will explain more about virtual DOM using programming example along with the graphical view.

React is a JavaScript library for building user interfaces. It is developed by Facebook to facilitate the building with the interactive, stateful and reusable UI components.

  • They are a great resource, but pick and choose wisely so that your project can continue to grow.After playing around with different options, I ultimately used vanilla javascript and event listeners for the keyboard shortcuts.
  • In app.js I wrote a handleKeyDown method:handleKeyDown(e) { if (e.ctrlKey e.which === 87) { this.props.toggleWebcamModal() } else if (e.ctrlKey e.which === 83) { this.props.openSaveModal() } else if (e.ctrlKey e.shiftKey e.which === 68) { this.handleClear() }}The numbers are unicode key values that are particular to a keyDown event.
  • Check out the link that I reference at the end: it lays out the different key code values for keyDown functions.
  • To set the event listener to listen for my keyDown commands, I used the lifecycle event, componentWillMount in app.js so that the listener begins to do it’s job right before the component mounts.
  • It is dispatched through the addons reducer and React rerenders app state as an empty array.I also created a tooltip that, on hover over the keyboard icon at the top of the screen, shows a menu of keyboard shortcuts!Deciding on a course of action with all of my options was the most time- consuming part of implementing the keybindings.

I am now a graduate of the Flatiron School! Check out https://o-lio.herokuapp.com/ to view my final project! To create Olio — defined as a miscellaneous collection of things — we created a Rails API…
