Lazy Loading😴😴 In React [Easy way]

#react #javascript #webdev #frontend

React lazy load package helps to load React component that renders children elements when they enter the viewport.

Lets Us see the live example for that I have used iTunes API to show the how react-lazy-load works.

Where I used it?

I used react lazy load component to wrap the image element. so that all images in the site doesn't fetch on the first request.

It only makes the fetch request whenever the user scrolls to that position.

Nice article Sai!

One humble suggestion, 'please format your code'. At first glance I couldn't understand what was going on as your code looks like this

export default (props)=>{

function formatDate(date, format){
    return moment(date).format(format);
  };

    return(
          <ul >
         </ul>
   )
}

No matter how cool the logic is, It is always a good idea to follow a consistent formatting.

I know fiddling with indentation sucks, that is why we have a tool called prettier, which takes care of formatting for you. I strongly suggest you use that.

Side note: Why do you need to define formatDate inside the react component ?

This looks like magic! Does it just get the next x amount of items from props? I have a JSON that I want to lazy load images from in this way, is there anything else I need to do?
