                    Do you mean to emit `F11` event ? https://stackoverflow.com/questions/7179535/set-window-to-fullscreen-real-fullscreen-f11-functionality-by-javascript – Revansiddh Jun 14 '19 at 11:53

        You can refer @chiragrupani/fullscreen-react package. It supports both class components and hooks/function components. Also, it supports allowing multiple elements to enter full screen. It's usage is simple as:
Install: npm i @chiragrupani/fullscreen-react
- Add button/icon which triggers full screen. You can also make it to toggle between entering and exiting full screen.
 
<button onClick={e => this.setState({isFullScreen: true})}>Go Fullscreen</button>
- Wrap the element that you want to enter fullscreen with FullScreen Component provided by npm package as shown below:
 
    <FullScreen
        isFullScreen={this.state.isFullScreen}
        onChange={(isFullScreen) => {
            this.setState({ isFullScreen });
        }}
        >
        <div>Fullscreen</div>
    </FullScreen>
For hooks, the code is similar:
export default function FSExampleHook() {
  let [isFullScreen, setFullScreen] = React.useState(false);
  return (
    <>
      <button onClick={(e) => setFullScreen(true)}>Go Fullscreen</button>
      <FullScreen
        isFullScreen={isFullScreen}
        onChange={(isFull: boolean) => {
          setFullScreen(isFull);
        }}
      >
        <div>Fullscreen</div>
      </FullScreen>
    </>
  );
}
PS: I am not author of this library, but I am using it in my production site.
