TypeScript and React: Pass component in props and return it from a function












2















I'm writing a Form component with React and TypeScript. I use Formik for the form logic. I want to pass the <Form /> component a specific form as a prop and render it. Here is what I tried:



import { Formik, FormikProps } from "formik";
import React, { PureComponent, ReactNode } from "react";

export interface Props {
component: ReactNode; // TODO: Change to one of LoginForm or RegisterForm.
handleSubmit(): void;
}

export class Form extends PureComponent<Props> {
renderForm = (formikProps: FormikProps<any>): ReactNode => {
const { component: FormComponent } = this.props;
return <FormComponent {...formikProps} />;
};

render() {
const { handleSubmit } = this.props;
return <Formik render={this.renderForm} />;
}
}

export default Form;


The problem is that the line where I return the <FormComponent /> throws the error:



[ts] JSX element type 'FormComponent' does not have any construct or call signatures.


renderForm has to return a ReactNode, so I can't change ReactNode to ComponentType (the latter would resolve the JSX error).



How would one do this in TypeScript?



Edit
So I got it working by doing this (thanks to estus):



import { Formik, FormikProps } from "formik";
import React, { PureComponent, ReactElement } from "react";

export interface Props {
component: React.ComponentType<any>; // TODO: Change to one of LoginForm or RegisterForm.
handleSubmit(): void;
}

export class Form extends PureComponent<Props> {
renderForm = (formikProps: FormikProps<any>): ReactElement<any> => {
const { component: FormComponent } = this.props;
return <FormComponent {...formikProps} />;
};

render() {
const { handleSubmit } = this.props;
return <Formik render={this.renderForm} />;
}
}

export default Form;
