[Feature Request] Intercepting hardcoded localhost WebSockets for HMR (.NET Hot Reload / dotnet watch)

Payload không nêu tên tệp hoặc bài kiểm thử nào của code-server. Hãy bắt đầu bằng cách lần theo việc xử lý ngữ cảnh trình duyệt đối với các WebSockets localhost gửi đi và lớp proxy tích hợp, sau đó kiểm tra cách aspnetcore-browser-refresh.js được chèn vào sử dụng các cổng ws/wss tạm thời. Kết quả cần là một quy trình làm việc dotnet watch thuần trình duyệt, trong đó Hot Reload kết nối thông qua code-server mà không gặp lỗi localhost.

What is your suggestion?

Implement a client-side interceptor or dynamic proxy mechanism within code-server's browser context that can catch outbound WebSocket requests to localhost:<port> and seamlessly route them through code-server's built-in proxy layer back to the remote workspace.

Why do you want this feature?

Developers relying on code-server for a pure browser-based development experience cannot use .NET's Hot Reload (dotnet watch).

When running dotnet watch, the .NET SDK dynamically injects a script (aspnetcore-browser-refresh.js) into the DOM that attempts to establish an HMR WebSocket connection to a random, ephemeral port on localhost (e.g., ws://localhost:40777).

Because the browser executes this locally, it queries the user's physical machine rather than the remote code-server container. The connection drops, and Hot Reload fails:
Firefox can’t establish a connection to the server at ws://localhost:40777/

Firefox can’t establish a connection to the server at ws://localhost:43067/.     aspnetcore-browser-refresh.js:318:25
WebSocket failed to connect.     aspnetcore-browser-refresh.js:19:15
Firefox can’t establish a connection to the server at wss://localhost:33935/.     aspnetcore-browser-refresh.js:318:25
WebSocket failed to connect.     aspnetcore-browser-refresh.js:19:15
Unable to establish a connection to the browser refresh server.     aspnetcore-browser-refresh.js:23:13

Are there any workarounds to get this functionality today?

There are no workarounds for a pure browser workflow (e.g., coding on an iPad or a locked-down laptop without CLI access).

Are you interested in submitting a PR for this?

No, I do not have the familiarity with the code-server networking/proxy codebase to implement this reliably.
