How to start nodejs with custom params from vscode

Question

Is there any way to start nodeJS with additional command line parameters?

like:

--harmony_generators
--harmony_arrow_functions

UPD:

workaround for now:

1. create .bat (windows) file with:

   • {{path-to-node}}\node.exe --harmony_generators --harmony_arrow_functions %*

2. add path to your .bat file as source of runtimeExecutable in .\settings\launch.json

3. profit :)

Answer 1

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"],

Answer 2

In My case I was running this command and parameter: node app.js read --title="SomeTitle"

and to solve that i used this:

"args": [
            "read",
            "\--\--title\=='SomeTitle'"
        ]

and the output was this:

node --inspect=10398 --debug-brk app.js read --title='Title'

That suited me well.

The suggestion to use runtimeArgs don't worked for me because its passed "before" invoking my app.js.
