Visual Studio Code not performing error checking in Javascript

Question

I've tried following these instructions:

https://code.visualstudio.com/Docs/runtimes/nodejs

I am not getting the green/red swiggly lines at all. Is there something I'm missing?

You can also see the same thing in this video:

As far as I know, they're running the default editor. I've tried installing typings and typescript using npm. I've Followed that tutorial to get Javascript intellisense for node.js, but I fail to get either error/warning checking or any type information for node.js modules.

Is there a location the type files should be installed to in order to make them global to every JS project you create in VS Code?

Answer 1

Maybe you didn't use the -g flag to install them globally? Alternately, perhaps it's a missing jsconfig.json file?

Answer 2

OK, so I managed get get some code suggestions working after reading up online. Without using the whole Typings tools, I acquired node.d.ts (found it on my computer inside C:\Program Files (x86)\Microsoft VS Code\resources\app\extensions) and placed that in my project's directory structure inside the ".vscode" folder. At the top of my .js file I added the following line:

/// <reference path=".vscode/node.d.ts" />

The code seems to be recognized now. I read up on this tip here: How to Import Intellisense files into vsCode (Visual Studio Code)

Answer 3

If you are using ESLint and you have an .eslint.js file in the project root you also need the eslint dependency installed in the project. Otherwise, if there is a .eslint.js file but the ESLint dependency is not installed Visual Studio Code will report nothing in the editor.
