TypeScript and React: Pass component in props and return it from a function
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty height:90px;width:728px;box-sizing:border-box;
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;

ReactNode
is React element type, while component
prop is expected to be React component.
It likely should be:
export interface Props
component: React.ComponentType;
handleSubmit(): void;
renderForm has to return a ReactNode, so I can't change ReactNode to ComponentType (the latter would resolve the JSX error).
component
prop and renderForm
return type aren't connected. The former is a component and the latter is an element.
