Using Higher Order Components in a React Application

  • If you have started using ReactJS recently often you might have felt that you are performing repeated logic in many components.
  • Well Higher Order Component (HOC) provides solution to such a kind of problems.
  • A function (Functional component in React) which takes a component and gives back another component.
  • So the exact benefits are:

    Functional components started from React V15.

  • But apart from that if we are careful enough we can have an architecture which can abstract logic that can be shared across other presentational components using HOC has great benefits.

If you have started using ReactJS recently often you might have felt that you are performing repeated logic in many components. For example consider an app having:

Using Props in React  #javascript #react #reactjs

  • In between the time it takes the first render of the component to fetching this data and setting it on our state that takes some time and during that time the length of videos is equal to 0 that is the reason that we see 0 for half a second when refreshing the page.
  • this.state = { videos: [] };When it is first rendered it does search of surfboards and it gets the response from this.stateApp is the parent of video list and video list need to get access to the videos that are in the app state.
  • passing data from the parent component App to the child component VideoList we are passing the list of videos just by defining a property on the JSX tag.Here we are passing video list to render method.
  • Anytime when App re render VideoList will get the videos as well.So now we have a functional VideoList component and it has array of videos to render.
  • Our video list component will receive props that contain an array of videos so we just loop over this array and for each video will generate one instance of video list for each item.Now each VideoListItem which is intended to show a single video now it will show a single li with a video.A map is a built in method that is a property of an array.

When we use functional component the props object will arrive as an argument to the function. const videos = props.videos; this is the array of videos. {props.videos.length} so this is saying that…

Higher Order Components: A React Application Design Pattern

Higher order components: A #ReactJS app design pattern

  • Because higher order components often wrap an existing component you’ll often find you can define them as a functional component.
  • You need some of your React components to be able to access this information, but rather than blindly making it accessible for every component you want to be more strict about which components receive the information.
  • A higher order function is a function that when called, returns another function.
  • We’ll discuss how pure functions keep code clean and how these same principles can be applied to React components.
  • In the React ecosystem these components are known as higher order components because they take an existing component and manipulate it slightly without changing the existing component .
