This is a quick post showing quickly how to make latest version of React Hook Form work with Ionic Framework ReactJS Components.

The previous post example will only work on older versions of the form library.

This is based on the Controller API discussed here in the documentation - https://react-hook-form.com/api#Controller

const App: React.FunctionComponent = () => {
  const { handleSubmit, control } = useForm();

  /**
   *
   * @param data
   */
  const onSubmit = (data: any) => {
    debugger;
    alert(JSON.stringify(data, null, 2));
  };

  return (
    <IonApp>
      <IonPage>
        <IonHeader>
          <IonToolbar>
            <IonButtons slot="start">
              <IonBackButton />
            </IonButtons>
            <IonTitle>Detail</IonTitle>
          </IonToolbar>
        </IonHeader>
        <IonContent>
          <p>Details</p>
          <form onSubmit={handleSubmit(data => console.log(data))}>
            <IonItem>
              <IonLabel>Gender</IonLabel>
              <Controller
                render={({ onChange, onBlur, value }) => (
                  <IonSelect placeholder="Select One" onIonChange={onChange}>
                    <IonSelectOption value="FEMALE">Female</IonSelectOption>
                    <IonSelectOption value="MALE">Male</IonSelectOption>
                  </IonSelect>
                )}
                control={control}
                name="gender"
                rules={{ required: true }}
              />

                    message: "invalid email address"
                  }
                }}
