How to start nodejs with custom parameters from vscode

Question

Is there a way to start nodeJS with additional command line options?

like:

- harmony_generators
--harmony_arrow_functions

UPD:

workaround:

• create a .bat (windows) file using

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

• add path to .bat file as runtimeExecutable source in . \ settings \ launch.json

• profit:)

Answer 1

In the VSCode preview version, it is not yet possible to pass the node arguments from the launch.json file. But the workaround mentioned above works fine. I created an error on our side and make sure that it is fixed with the next version.

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, for example, run Node.js (v0.12) with ES6 support "runtimeArgs": ["--harmony"],

Answer 2

In my case, I ran this command and parameter: node app.js read --title = "SomeTitle"

and decide that I used this:

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

and the output was as follows:

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

I really liked it.

The suggestion to use runtimeArgs does not work for me because it passed the "before" call to my app.js.

With the current version 1.36.1, you can add arguments to your launch.json Example:

 { "version": "0.2.0", "configurations": [ { "type": "node", "request": "launch", "name": "Launch Program", "program": "${workspaceFolder}/index.js", "args":["my-url=http://192.168.1.24:8984/api/", "port=3000"] } ] } 

In your node application, you can capture Args:

  process.argv.forEach(function (val, index, array) { console.log(val); } 

Now you can start debugging Visual Studio code and see how the arguments are displayed

If you run the application from the console , it should look like this:

 node index.js my-url=http://192.168.1.24:8984/api/ port=3000 

The result in both cases:

 my-url=http://192.168.1.24:8984/api/ port=3000

Edit ./settings/launch.json (debug menu> gear icon)

There is an args entry here that you can edit
