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…

The Provider and Higher-Order Component patterns with React

The provider and higher-order component patterns with #ReactJS:

  • The best way to create a reusable functionality is a Higher-Order Component.
  • const React, { Component, PropTypes } from “react” const theme = (ComponentToWrap) => { return class ThemeComponent extends Component { // let’s define what’s needed from the `context` static contextTypes = { theme: PropTypes.object.isRequired, } render() { const { theme } = this.context // what we do is basically rendering `ComponentToWrap` // with an added `theme` prop, like a hook return ( ) } } } export default theme
  • import React, { Component, PropTypes, Children } from “react” class ThemeProvider extends Component { static propTypes = { theme: PropTypes.object.isRequired, } // you must specify what you’re adding to the context static childContextTypes = { theme: PropTypes.object.isRequired, } getChildContext() { const { theme } = this.props return { theme } } render() { // `Children.only` enables us not to add a

    for nothing return Children.only(this.props.children) } } export default ThemeProvider

  • With the Provider , you are now able to pass the theme to any component who requires it.
  • Now that our theme is added to the context , we need a simple way for the components to grab it.

Lots of React libraries need to make their data pass through all your component tree. For instance, Redux needs to pass its store and React Router needs to pass the current location. This could…
