Typescript: How to add type check for history object in React?

Question

I have the following piece of code, which receives a history object as prop:

const ChildComponent = ({ history }) => (

You can use the RouteComponentProps interface, which declares all props passed by withRouter:

import { RouteComponentProps } from 'react-router-dom';
..
interface ChildComponentProps extends RouteComponentProps {
  /* other props for ChildComponent */
}
const ChildComponent : React.SFC = ({ history }) => (
  ..
);

The type parameter to RouteComponentProps is the type of the params property in match, so you won't need it unless you're matching named path segments.

Alternatively, if history doesn't come from withRouter but is passed by itself as a prop, you can import the type from history:

import { History } from 'history';
..
interface ChildComponentProps {
  history : History
  /* other props for ChildComponent */
}
const ChildComponent : React.SFC = ({ history }) => (
  ..
);
