fix: add `"EADDRINUSE"` as `code` to server `Error` #4045

Closed davidmurdoch closed 1 year ago

davidmurdoch commented 1 year ago

This PR sets the code property related to the error "listen EADDRINUSE: address already in use { address }" to "EADDRINUSE", making detecting this kind of "address in use" error programmatically much easier and straightforward. This property existed in Ganache v6 and earlier and was removed in v7.0.0 in error.

Previously:

{
  "message": "listen EADDRINUSE: address already in use 127.0.0.1:5001"
}

Now:

{
  "code": "EADDRINUSE",
  "message": "listen EADDRINUSE: address already in use 127.0.0.1:5001"
}

Fixes #4020
