To fix CORS request issues for a socket.io connection with a webpack proxy, you can add a proxy configuration in your webpack configuration to proxy requests to the socket.io server. Here's how you can do it:

  1. In your webpack configuration file, add a proxy configuration to proxy requests to the socket.io server. For example, you can add the following code snippet:
1
2
3
4
5
6
7
8
devServer: {
  proxy: {
    '/socket.io': {
      target: 'http://localhost:3000', // Your socket.io server URL
      ws: true
    }
  }
}


  1. Make sure to replace 'http://localhost:3000' with the actual URL of your socket.io server.
  2. Restart your webpack dev server for the changes to take effect.


By configuring the webpack dev server to proxy requests to the socket.io server, you should no longer encounter CORS issues when making socket.io requests from your client-side code.
