Proxy in package.json not affecting fetch request

I am trying to fetch some data from the development server using React.

I am running the client on localhost:3001 and the backend on port 3000.

The fetch request :

 const laina = fetch('/api/users');
    laina.then((err,res) => {
      console.log(res);
    })

When I run my development server and webpack-dev-server I get the following output:

GET http://localhost:3001/api/users 404 (Not Found)

I tried specifying the proxy in the package.json so it would proxy the request to the API server, however nothing has changed.

Here is my package.json file:

.. and the webpack.config :

Please tell me, if you need to see anything else from my project. I apologies, if I'm missing something and not being thorough, I'm still quite new to using these technologies.
