Document how to use plugin configuration via ESLint

[fregante]

eslint-config-xo can be used from eslint:

{
	"extends": "xo"
}

But it does not include the plugin config:

https://github.com/xojs/xo/blob/a30cf0b710063953a015066bdfd9514eab41900c/config/plugins.cjs

Is it possible to move it to eslint-config-xo and use it as such?

{
	"extends": [
		"xo",
		"xo/import",
		"xo/node",
		etc

		// or
		
		"xo/with-plugins",
	]
}

Same answer as #618 (comment)

Is it? I'm setting most plugin configuration via my custom config here, both via extend: [plugin:"import/recommended"] and by setting each rule:

https://github.com/fregante/eslint-config-pixiebrix/blob/60f5a8837066009757fc293faa65636ad57fde14/index.js#L27-L31

And then I'm just extending the single shared config as usual:

https://github.com/pixiebrix/pixiebrix-extension/blob/2914608a3c37ebd93fecc03781449b9f79acefd9/.eslintrc#L3-L6

I'm not even installing each plugin separately, they're part of eslint-config-pixiebrix’ dependencies

https://github.com/pixiebrix/pixiebrix-extension/blob/2914608a3c37ebd93fecc03781449b9f79acefd9/package.json#L217-L218

I think technically I could add xo as a dependency and use extend: ["./node_modules/xo/config/plugins.cjs"], but that obviously is a mess.

[fregante]

If it doesn't break the current usage, I'd move plugins.cjs to the eslint-config-xo package as its own file. XO can continue to import it as usual, I suppose, and others will be able too.

eslint/eslint#3458

[fregante]

I know, but it works for me and I don't know why.

Either way, my suggestion was not to change the dependency setup, but just to move the file to the eslint-config-xo, which should still be fine for XO itself and has the potential of working for others through the config as well.

[sindresorhus]

Even if it works for you, it's not something that is officially supported. I have wasted so much time on weird config resolution issues with XO and ESLint in the past year. I don't want to risk any more issues by moving the file out. I recommend just copy-pasting the useful stuff in plugins.js for now. This will all be fixed properly at some point.

Speaking of which: 0.46.1 0.46.2 0.46.3 😅

I was having issues with it yesterday but did not have the time to investigate

[sindresorhus]

Yeah... Try 0.46.3. It fixes it for sindresorhus/ow at least.
