Using Semiotic if You’ve Never Used React – Elijah Meeks – Medium

  • Using Semiotic if You’ve Never Used ReactI released Semiotic to help folks using React deploy better data visualization.
  • If you’re interested in also understanding D3v4 better, my 2nd edition of D3.js in Action has a chapter on React that explains its core concepts from the perspective of a data visualization developer familiar with D3.Setting up Your React AppFor those of you coming from traditional web development with static source files included in your HTML doc, the biggest hurdle is the modern JavaScript development environment.
  • Now that you have Semiotic installed, you can import any of its components and use them almost as you see them in the interactive examples in the documentation.Using Semiotic in Your AppI say “almost” because the examples have code that look like this:const answers = [ {“question”:”Question 1″, “type”:”disagree”, “color”:”#d38779″, “value”:-294, “percent”:-0.09}, {“question”:”Question 1″, “type”:”stronglydisagree”, “color”:”#b3331d”, “value”:-24, “percent”:-0.007}, {“question”:”Question 1″, “type”:”agree”, “color”:”#00a2ce”, “value”:1927, “percent”:0.59}]import { ORFrame } from ‘semiotic’export default ORFrame size={[ 700,500 ]} data={answers} type=”bar” projection=”horizontal” oAccessor={“question”} rAccessor={“percent”} style={d = ({ fill: d.color })} margin={{ top: 30, bottom: 0, left: 80, right: 50 }} oPadding={20} oLabel={true} axis={{ orient: “top”, tickValues: [ -0.3, -0.15, 0, 0.2, 0.4, 0.6, 0.8, 1]}}/And that’s not really React ready.
  • Rather than just directly exporting or using ORFrame like you see above, you need to drop it somewhere in the render function of the component where you want to have data visualization.
  • So the real code would look more like this:import React from “react”;import { ORFrame } from ‘semiotic’const answers = const answers = [ {“question”:”Question 1″, “type”:”disagree”, “color”:”#d38779″, “value”:-294, “percent”:-0.09}, {“question”:”Question 1″, “type”:”stronglydisagree”, “color”:”#b3331d”, “value”:-24, “percent”:-0.007}, {“question”:”Question 1″, “type”:”agree”, “color”:”#00a2ce”, “value”:1927, “percent”:0.59}]export default class DivergingStackedBar extends React.Component {render() {return (divh1A diverging Bar Chart With Negative Values/h1ORFrame size={[ 700,500 ]} data={answers} type=”bar” projection=”horizontal” oAccessor={“question”} rAccessor={“percent”} style={d = ({ fill: d.color })} margin={{ top: 30, bottom: 0, left: 80, right: 50 }} oPadding={20} oLabel={true} axis={{ orient: “top”, tickValues: [ -0.3, -0.15, 0, 0.2, 0.4, 0.6, 0.8, 1]}} //div) } // End of the render function} // End of the componentYou may wonder why I put the data array outside of the render function.

I released Semiotic to help folks using React deploy better data visualization. But since announcing its release I’ve heard from a few people who want to try to develop with Semiotic but have never…

Simple React Router Example – Dan Buda – Medium

Simple React Router Example  #router #reactjs #react #reactjs

  • One of the things I love about React is how easy it is to make components and bring them all together.We’ll need to import a few things from React React Router Router to be able to make it all work.
  • And in our Link tags, we’ve included a to= and a path name that will be used in our Router code.So now for the Router:We use ReactDOM.render to tell our app how the navigation all fits together.
  • First, we want to use browserHistory in the main Router tag, and give our Router a starting point:So our App component, which will house our other components, is set up as the parent route that will use the path of just “/”.
  • Now we can add our Home component using IndexRoute to tell our Router that Home should load first upon getting to the site.The Home component/route is set up inside the App route because we want to set it as a child of App.
  • And now we can add our 2 link pages to the router:They are also added as children of the App component.

Just the basics of using React Router (version 2.8.1 — v4 just came out and I’ll monkey with that soon). So you can use React Router to handle all of your navigation, and once getting used to it, it…

React Native’s new FlatList component – Hacker Noon

React Native’s new FlatList component explained:

  • React Native’s new FlatList componentIncluding: How to migrate from ListView (soon to be deprecated), and how to try it in your own app without building React Native from source.The demo video posted on Facebook by Ahrens.
  • Everything below is still up-to-date and accurate.Update: There are now multiple new components: FlatList, SectionList, VirtualizedList, and VirtualizedSectionList.
  • Update: The original ListView is planned to be deprecated.Earlier in February, Spencer Ahrens published an experimental new React Native component called FlatList.
  • Copy this whole command into your terminal:This will download the latest version of FlatList and its related dependencies into your app’s node_modules so you can refer to it as in the examples above, without needing to checkout React Native’s master and build it from source.You could, for example, add the above command to your package’s postinstall script to make sure the files exist for every developer and build pipeline on your team (thanks to Bruno Lemos for this tip).
  • There’s a more extensive FlatListExample in React Native’s repo if you want to get a feel for the full set of props and how powerful the new component can be.

Including: How to migrate from ListView (soon to be deprecated), and how to try it in your own app without building React Native from source.

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

How we found and installed react fiber

How we found and installed #ReactJS fiber:  via @wschenk #Javascript

  • The other day, Rob Welan one of our awesome team, sent me a link to React Fibre.
  • After some research I found out that React Fiber may be coming to React 16.0.0 and is currently being developed in the Facebook React Master Branch .
  • Anytime you want to update just run in the react folder git pull origin master followed by npm run build and your app will be automatically updated.
  • /react/build/packages/react and npm link ..
  • Next you’ll want to cd into the react folder and run npm install followed by npm run build .

Recently we’ve been working on developing an amazing refresh of our client’s home automation web controller. We’ve been developing the front-end using React, Babel and Redux and have been absolutely loving it. It has been a steep initial learning curve but we found that was mostly because we were being “forced” to learn functional programming #winning.
