How To Import Plain Javascript Helper Classes Into React?

I have a React class that I have written in ES6 style such as: export default class App extends React.Component { constructor(props) { super(props); let HClass

Solution 1:

Currently, new HelperClass() is only available inside your constructor. You can use the some_function there only.

Generally, you'll do:

For use inside specific method:

// outside the constructormyMethod() {
  let HClass = newHelperClass();
  HClass.some_function();
}

For use in any method:

// inside the constructorthis.props.HClass = new HelperClass();

// to callthis.props.HClass.some_function();

Or, simply using this:

// inside the constructorthis.HClass = newHelperClass();

// to callthis.HClass.some_function();
