How to start nodejs with custom params from vscode

In the preview version of VSCode it is not yet possible to pass arguments to node from the launch.json. But the workaround mentioned above works fine.
I have created a bug on our side and will make sure it’s fixed with the next release.

Update:

The fix is in VSCode since v0.3 with this in .settings/launch.json:

"configurations": [
    {
        ...

        // Optional arguments passed to the runtime executable.
        "runtimeArgs": [],

        ...

So to e.g. run Node.js (v0.12) with ES6 support use "runtimeArgs": ["--harmony"],
