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 users = fetch('/api/users');
    users.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 : enter image description here

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.

Solution

  • You can modify your fetch request API url to give the complete hostname since 

     fetch('http://localhost:3000/api/users')

    also make sure that you have CORS enabled on your backend

    In case your want to redirect through webpack, your can try devServer.proxy as

    devServer: { 
    inline: true, 
    contentBase: './dist', 
    port: 3001, 
    proxy: { "/api/**": { target: 'http://localhost:3000', secure: false }  }
 }
