⚛️ 🚀 Introducing React-Static — A progressive static-site framework for React!

  • How well that static site performs and how easily you can build that site is another story.ProsVery easy to get startedWell documentedConsSubpar developer experience for static functionality no hot-reloadingLarge per-page JS bundles, resulting in a lot of unnecessary duplicate code being downloaded.Difficult root component customizationDestructive routing.
  • We also knew that we needed to ditch built-in proprietary connectors ASAP; being able to get your data from anywhere is important, but the ability to use and access that data in your site is paramount.Most importantly, we needed a tool that would allow us to build things like an…
  • It’s insanely fast, touts fantastic SEO capabilities, and is probably the most React-friendly static-site library on the internet.Let’s get to it.How does it work?react-static starts by exporting a single JS bundle, which includes every template for your entire site.
  • To connect a component to this data, you use a convenient HOC called getRouteProps.The HTML files generated by react-static ensure that pages load instantly and are optimized for SEO.Once the page is loaded, your site invisibly and instantly transitions to your react app.At this point, navigating around your app will…
  • You’ve worked hard enough producing and organizing all of the data for your website, so the last thing you need is some superfluous GraphQL layer or custom component lifecycle lodging itself between your data and your pages.

Props and Data Flow in ReactJS – Kenlyn Terai – Medium

Props and Data Flow in #ReactJS:  #JavaScript

  • (3) There are only two requirements that define a JavaScript function as a React component:The function accepts a single “props” object argument with dataIt returns a React elementA simple “Functional” componentThe equivalent “Class” componentWhether you declare a component as a function or a class, it must never modify its own props.
  • All React components must act like pure functions with respect to their props.
  • = BoringTo sum up what props are in React, theyAre data passed to components — values can be anything: a string, an array, functions, and so onAre immutableEnable components to become more reusableSo, if props are read-only, what place do they have in creating dynamic web applications?
  • The render() method also calls the diff algorithm which recognizes any changes in the component and logs them for batching to the “real” DOM.Credit: Tarun Sharma: “Understanding virtual DOM react js” from React DocsHere is an example from Components and Props in the React Docs.
  • This code renders “Hello, Sara” on the page:function Welcome(props) { return h1Hello, {props.name}/h1;}const element = Welcome name=”Sara” /;ReactDOM.render( element, it on CodePen.Let’s recap what happens in this example:We call ReactDOM.render() with the Welcome name=”Sara” / element.React calls the Welcome component with {name: ‘Sara’} as the props.Our Welcome component returns a h1Hello, Sara/h1 element as the result.React DOM efficiently updates the DOM to match h1Hello, Sara/h1.

ReactJS comes with a slew of new words and new definitions for existing ones. “Props” is no exception. To understand the meaning of “props” in ReactJS, I turned to the context where it is used — in…
