Get path params in react-router v4

In order to receive the path param in you component, you need to first connect your component with withRouter HOC from react-router so that you can access the Router props and get the path params from the match props as this.props.match.params.id

Sample Code:

import {withRouter} from 'react-router';

class BookDetailedView extends React.Component {
    render() {
        var id = this.props.match.params.id


    }
}
export default withRouter(BookDetailedView) ;

or simply passing it with render prop in route as

<Route path="/details/:id" render={({match}) => (
          <BookDetailedView
            bookStateUpdated = {this.bookStateUpdated}
            book = {this.state.books}
            id={match.params.id}
          />
)}/>

From the React Documentation of match

match

A match object contains information about how a <Route path> matched
the URL. match objects contain the following properties:

• params – (object) Key/value pairs parsed from the URL corresponding to the dynamic segments of the path
• isExact – (boolean) true if the entire URL was matched (no trailing characters)
• path – (string) The path pattern used to match. Useful for building nested s
• url – (string) The matched portion of the URL. Useful for building nested s

You’ll have access match objects in various places:

1. Route component as this.props.match
2. Route render as ({ match }) => ()
3. Route children as ({ match }) => ()
4. withRouter as this.props.match
5. matchPath as the return value

If a Route does not have a path, and therefore always matches, you’ll
get the closest parent match. Same goes for withRouter
