Redirect to previous path on login - React Router v4

Question

I am using react router v4 and trying to implement a functionality where no matter what route the user clicks on, he gets taken to the login page i.e. if he is not logged in

Answer 1

Previous answers are not detail enough.

Solution:

Router

  
    {publicRouteList()}
    
    {getLoggedRouteList(state.logged)}
    
  

getLoggedRouteList

const getLoggedRouteList = (logged) => {
  if (!logged) {
    return (
       {
          return (
            
          );
        }}
      />
    );
  }

  const output = [];
  output.push(
    /* Here place route list that need logged */
  );
  return output;
}

Login Component

class Login extends React.Component {
  login = async param => {
    const { location } = this.props;
    const { state } = location;

    /* Here place request login api */

    // go to state.from if set before
    if (state && state.from) {
      history.replace(state.from);
    }
    // else go to home
    else {
      history.replace('/');
    }
  }
}
