As I understand <Route path="/" component={App} /> will gives App routing-related props like location and params. If my App component has many nested child components, how do I get the child component to have access to these props without:
- passing props from App
- using window object
- creating routes for nested child components
I thought this.context.router would have some information related to the routes, but this.context.router seems to only have some functions to manipulate the routes.

You can use useNavigate, useLocation and useMatch in your component to get matchPath, navigate and location .
const Child = () => {const location = useLocation();const navigate = useNavigate();const match = useMatch("write-the-url-you-want-to-match-here");return (<div>{location.pathname}</div>)}export default ChildV5.1 & Hooks (Requires React >= 16.8)
You can use useHistory, useLocation and useRouteMatch in your component to get match, history and location .
const Child = () => {const location = useLocation();const history = useHistory();const match = useRouteMatch("write-the-url-you-want-to-match-here");return (<div>{location.pathname}</div>)}export default ChildV4 & V5
You can use withRouter HOC in order to inject match, history and location in your component props.
class Child extends React.Component {static propTypes = {match: PropTypes.object.isRequired,location: PropTypes.object.isRequired,history: PropTypes.object.isRequired}render() {const { match, location, history } = this.propsreturn (<div>{location.pathname}</div>)}}export default withRouter(Child)V3
You can use withRouter HOC in order to inject router, params, location, routes in your component props.
class Child extends React.Component {render() {const { router, params, location, routes } = this.propsreturn (<div>{location.pathname}</div>)}}export default withRouter(Child)Original answer
If you don't want to use the props, you can use the context as described in React Router documentation
First, you have to set up your childContextTypes and getChildContext
class App extends React.Component{getChildContext() {return {location: this.props.location}}render() {return <Child/>;}}App.childContextTypes = {location: React.PropTypes.object}Then, you will be able to access to the location object in your child components using the context like this
class Child extends React.Component{render() {return (<div>{this.context.location.pathname}</div>)}}Child.contextTypes = {location: React.PropTypes.object}If the above solution didn't work for you, you can use import { withRouter } from 'react-router-dom';
Using this you can export your child class as -
class MyApp extends Component{// your code}export default withRouter(MyApp);And your class with Router -
// your code<Router>...<Route path="/myapp" component={MyApp} />// or if you are sending additional fields<Route path="/myapp" component={() =><MyApp process={...} />} /><Router>
