How to use React’s Provider Pattern

How to use React's Provider Pattern  #reactjs #webdev

  • Therefore you could use React’s context to give every component access to the colored theme.
  • That way every component that needs to be styled according to the colored theme could get the necessary information from React’s context object.
  • You have the Provider component that makes properties accessible in React’s context and components that consume the context.
  • This Provider component uses React’s context to pass down the state implicitly.
  • You provide the state to your component as props, the component wraps it into React’s context and all child components can access the state by using a higher order component such as from the react-redux library.

This article gives you a walkthrough for React’s provider pattern. After reading it, you should be able to implement…

Now that it’s okay to use @reactjs again, I can say: I’ve been working on this @WordPress + React thing for awhile

  • Postlight’s Headless WordPress + React Starter Kit is an automated toolset that will spin up two things: – – The following setup will get WordPress running locally on your machine, along with the WordPress plugins you’ll need to create and serve custom data via the WP REST API.
  • To install and start WordPress, run the following command: – – When that completes successfully, the WordPress REST API will be available at http://localhost:8080.
  • To import data and media from a live WordPress install locally, use Migrate DB Pro.
  • At this point you can start setting up custom fields, and if necessary, creating custom REST API endpoints in the Postlight Headless WordPress Starter theme.
  • Once you have Docker installed on your computer, you can run the container locally using this command:

8 things to learn in React before using Redux

8 things to learn in #ReactJS before using #Redux:

  • A component can manage a whole lot of state, pass it down as props to its child components and pass a couple of functions along the way to enable child components to alter the state in the parent component again.
  • Component A is the only component that manages local state but passes it down to its child components as props.
  • In addition, it passes down the necessary functions to enable B and C to alter its own state in A.

    Now, half of the local state of component A is consumed as props by component C but not by component B.

  • When you lift the local state management down to component C, all the necessary props don’t need to traverse down the whole component tree.
  • When a library such as Redux “connects” its state managements layer with React’s view layer, you will often run into a higher order component that takes care of it (connect HOC in react-redux).

Facts about React that should be known before using Redux (or MobX). Most important: Learn React first, then opt-in Redux…

Stop Managing CSS – Charlie Hulcher – Medium

Stop Managing CSS  #cssinjs #react #styledcomponents #css #http2 #reactjs

  • Stop Managing CSSA response to Managing CSS JS in a HTTP/2 WorldThis article on getting great performance out of HTTP/2 would have excited me hugely before.
  • Sane structure and tooling around SCSS that allows for the best loading benefits with HTTP/2 is definitely the future when your styles are separate from everything else.I believed in separating styles, behavior, and structure for a long time.
  • Keep style alongside behavior and structure.Coming from that context, reading about the right way to manage CSS felt like watching exciting evolution for a dated paradigm.
  • A cleaner design for a horse harness is a beautiful thing but doesn’t beat the engine.Solving the problem of chunked CSS delivery in order to get performance benefits from HTTP/2 sounds to me like reinventing the wheel from what you’re probably already doing.
  • Why rebuild that process in parallel for CSS?The core problem comes down to managing CSS inclusion/exclusion from the project through a human process.
