Usage

• react-use-scripts will return a default export useScript and a named export { ScriptLoader }
• Use ScriptLoader as an element in your JSX and add optional children and/or fallback rendering

import * as React from 'react';
import { ScriptLoader } from 'react-use-scripts';

const App = () => {
  return (
    <ScriptLoader
      id="custom-script-id"
      src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"
      delay={500}
      onReady={() => console.log('ready!')}
      onError={(error) => console.log('an error has happened!', error)}
      fallback={(error) => (
        <span>This has errored! {JSON.stringify(error)}</span>
      )}
    >
      <span>Script has loaded succesfully!
    </ScriptLoader>
  );
};

• Append scripts to the document programmatically

import * as React from 'react';
import useScript from 'react-use-scripts';

const App = () => {
  const [startTrigger, setStartTrigger] = React.useState(false);
  const { ready, error } = useScript({
    src: 'https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js',
    onReady: () => console.log('ready!'),
    onError: (error) => console.log('an error has happened!', error),
    startTrigger,
  });

  const handleAppendScriptClick = () => {
    setStartTrigger(true);
  };

  return (
    <div>
      <button onClick={handleAppendScriptClick}>
        Click to start appending
      </button>
      {ready && <h1>Script appended to the head programmatically!</h1>}
      {error && <h1>Script has errored! {JSON.stringify(error)}</h1>}
    </div>
  );
};
