Getting the current url on the client side in next.js

问题

So I am working on a nodejs app which I will have my new website on and I want to make a way for my user on the clientside to display different things, re-renderd depending on what the user is pressing on. My idea is that for example firstly the user would see "Please select a tool first" and then the user will select a tool in the navbar which then the page will be re-renderd and display the tool selected inside a jumbotron with the url being changed for example then /admin/[ToolSelected]. The only thing is tho that I do not know how to achive this. I was thinking that the client side code could detect what the url is and is placed as a page variable then the tool will displayed with a IF statement depending on what the page variable is.

Would my theory work or how can a achive this in a efficent way?

Here is my main page code:

// Including Navbar and css
import AdminLayout from '../comps/admin/adminLayout'

// the so called "tools" more will exist in the future
import Passform from '../comps/admin/tools/passform'


// Fetching the current url the user is on
var page = CURRENT_URL;


const jumbotron = {
  background: 'white'
}

const Admin = (page) => (

  <AdminLayout>

  <style global jsx>
  {
    `body {
      background: #eff0f3;
    }`
  }
  </style>
    <div className="jumbotron" style={jumbotron}>

    {(page == "passform") ? (
      <Passform/>
    ) : (
      <h3>Something is wrong :/ . {page}</h3>
    )}

    </div>
  </AdminLayout>
)

export default Admin

You can wrap your component with withRouter HOC, that will inject the router object, that has current pathname.

import { withRouter } from 'next/router';

const Admin = ({ router }) => (
  <AdminLayout>
    <style global jsx>
      {`
        body {
          background: #eff0f3;
        }
      `}
    </style>
    <div className="jumbotron" style={jumbotron}>
      {router.pathname == 'passform' ? <Passform /> : <h3>Something is wrong :/ . {page}</h3>}
    </div>
  </AdminLayout>
);

export default withRouter(Admin);
