  • 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.

The provider pattern in React is a powerful concept. You will not often see it when using plain React, but might consider using it when scaling your application in React. Basically it takes the clutter away of passing mandatory props, that are needed by every component, down your whole component tree.

But you will not only see it when using plain React. Often React’s provider pattern can be seen in action when using an external state management library. In Redux or MobX, you often end up with a component at the top of your component hierarchy that bridges your state layer (Redux/MobX/…) to your view layer (React). The component gets the state as props and after that each child component has implicitly access to the managed state.

But how does this work? This article gives you a walkthrough for React’s provider pattern. After reading it, you should be able to implement your own Provider in React. In addition, you will understand how a component in Redux or MobX works, if you have encountered these already.

There are two things you have to know about React before you can implement your own provider pattern in React: children and context.

React’s children are useful for nesting React components into each other. It is similar to nesting HTML tags into each other. You would only use React’s JSX syntax to accomplish it.
