How to use OXC in VS Code with nested config files?

[daronspence]

Hello!

New to a lot of JS toolchain stuff so apologies if this is a dumb question.

I have a Laravel monorepo with 8 different apps. On our customer facing application, I want to enable OXC for linting of JS/Vue files. The documentation describes OXC as "no config" but I'm having issues making any of it work at all.

I installed the extension into VS Code. I do NOT have the Eslint extension enabled. Is that also required? Do I need an extra extension to get the squigglies to appear?

If I run npx oxlint@latest from the root of my customer applicatin, it does work as expected, but I get zero feedback onType or onSave when modifying .vue or .js files.

The oxc_language_server output has no errors and even after enabling tracing in the extension settings and restarting, I see nothing in the trace output either. My config file is located at /Users/daron/Work/project/Client-Application/.oxlintrc.json but I have the project folder open at the root of my workspace. If I open just the Client-Application as a standalone project, it still doesn't work.

Here is my oxlintrc.json config:

{
    "env": {
        "browser": true
    },
    "globals": {
        "AppData": "readonly"
    },
    "settings": {},
    "rules": {
        "eqeqeq": "warn",
        "import/no-cycle": "error"
    }
}

I tried writing the following code in a .vue component and expected to at least see some errors re: the == usage. Unfortuantely, I see no errors. If I run the CLI command, I do see those lines in the output.

if (1 == 2) {
    console.log('test');
}
const thing = (testing, unused) => {
    if (testing == 1) {
        console.log('hi me');
        unused--;
        debugger;
    }
}

Happy to provide more details. I saw the presentation at Vite Conf and wanted to give it a shot!

I also installed oxc extension but I cannot use it. 😭 I created a question at here.

Nested configuration isn’t supported yet. It is listed as a feature expected to be available before the Oxlint beta #5653.
