How to make a React Error Boundary with Typescript

I found this over here and I'm shamelessly copying it here for quick reference.

import React, { Component, ErrorInfo, ReactNode } from "react";

interface Props {
  children: ReactNode;

interface State {
  hasError: boolean;

class ErrorBoundary extends Component<Props, State> {
  public state: State = {
    hasError: false

  public static getDerivedStateFromError(_: Error): State {
    // Update state so the next render will show the fallback UI.
    return { hasError: true };

  public componentDidCatch(error: Error, errorInfo: ErrorInfo) {
    console.error("Uncaught error:", error, errorInfo);

  public render() {
    if (this.state.hasError) {
      return <h1>Sorry.. there was an error</h1>;

    return this.props.children;

export default ErrorBoundary;

For more fun maybe pass in a component for it to default to. idk go nuts.
