Navigate using react-router-dom v6 after performing user action

Question

I started learning react about 15 days back. The following code adds the post correctly but does not redirect to "/". I am using react-router-dom v6.

render(){
  return <div>
              <Routes>
                <Route exact path="/" element={
                      <div>
                      <Title title={'Arijit - Photowall'}/>   
                        <Photowall posts={this.state.posts} onRemovePhoto={this.removePhoto} /> 

                      </div>

      } >
                          </Route>
                    <Route path="/addPhotos" element={ 
                     
                    <AddPhoto onAddPhoto={(addedPost)=>{
          
                      this.addPhoto(addedPost)
                      
                      
                      }}
                      
                      >
                        <Navigate to="/" />
                      </AddPhoto>
                      
                     }/>
                  </Routes>
        </div>
}

In react-router-dom@6 the way to issue imperative navigation actions is to use the navigate function returned from the useNavigate hook. The code you've shared in the snippet is from a class component though, so you'll need to create a Higher Order Component to use the useNavigate hook and inject the navigate function as a prop.

Example:

import { useNavigate } from 'react-router-dom';

const withNavigate = Component => props => {
  const navigate = useNavigate();
  return <Component {...props} navigate={navigate} />;
};

Decorate the component in your snippet with this withNavigate HOC.

export withNavigate(MyComponent);

Access the navigate function from props.

render(){
  const { navigate } = this.props;

  return (
    <div>
      <Routes>
        <Route
          path="/"
          element={(
            <div>
              <Title title={'Arijit - Photowall'}/>   
              <Photowall posts={this.state.posts} onRemovePhoto={this.removePhoto} /> 
            </div>
          )}
        />
        <Route
          path="/addPhotos"
          element={( 
            <AddPhoto
              onAddPhoto={(addedPost) => {
                this.addPhoto(addedPost);
                navigate("/");
              }}
            />
          )}
        />
      </Routes>
    </div>
  );
}

Routes must be contained into a Router (Usually) BrowserRouter, so, you should put them all inside of that component, something like this:

<BrowserRouter>
    <div className="App">
      <Box data-testid="app-container">
        <Routes>
          <Route path={"/"} element={<Home />} />
          <Route path={"/edit"} element={<edit/>} />
          <Route path={"/whatever"} element={<whatever/>} />
        </Routes>
      </Box>
    </div>
</BrowserRouter>

regarding to the navigate, in react-router-dom v6 you must use the hook useNavigate() and it works as:

  const navigate = useNavigate();

   <Button
       text={ES.common.back}
       onClick={() => navigate("/")}
   ></Button>

You'll have to import

import { useNavigate } from "react-router-dom";
