Usage with class components

If you want to use the useSession() hook in your class components you can do so with the help of a higher order component or with a render prop.

Higher Order Component

import { useSession } from "next-auth/client"

const withSession = (Component) => (props) => {
  const [session, loading] = useSession()

  // if the component has a render property, we are good
  if (Component.prototype.render) {
    return <Component session={session} loading={loading} {...props} />
  }

  // if the passed component is a function component, there is no need for this wrapper
  throw new Error(
    [
      "You passed a function component, `withSession` is not needed.",
      "You can `useSession` directly in your component.",
    ].join("\n")
  )
}

// Usage
class ClassComponent extends React.Component {
  render() {
    const { session, loading } = this.props
    return null
  }
}

const ClassComponentWithSession = withSession(ClassComponent)

Render Prop

import { useSession } from "next-auth/client"

const UseSession = ({ children }) => {
  const [session, loading] = useSession()
  return children({ session, loading })
}

// Usage
class ClassComponent extends React.Component {
  render() {
    return (
      <UseSession>
        {({ session, loading }) => (
          <pre>{JSON.stringify(session, null, 2)}</pre>
        )}
      </UseSession>
    )
  }
}
