ESLint Configuration

This repository is Xola's shared ESLint rules only. It ships a flat config (a rule set) that host projects extend. It does not provide a linter binary or CLI, and it is not a replacement for ESLint itself. Each host project installs and runs its own eslint (and typescript for the type-aware rules); this package only supplies the rules they use.

Two configs are exported: the default/. config for React projects, and ./node for plain Node/TypeScript projects with no React.

Installation

Install the @xola/jslint package as a devDependency in your host project, alongside eslint and typescript, which are peer dependencies you provide.

npm install -D @xola/jslint eslint typescript

Setup

To use the shared config, import the package inside of an eslint.config.mjs file and add it into the exported array, like this:

// eslint.config.mjs
import xolaLint from "@xola/jslint";

export default [...xolaLint];

Then lint with ESLint directly in your host project's scripts (this package does not wrap it):

{
    "scripts": {
        "lint": "eslint --cache --cache-strategy content --fix src",
        "lint:ci": "eslint --cache --cache-strategy content src",
        "lint:report": "eslint --cache --cache-strategy content --output-file=eslint_report.json --format=json src"
    }
}

Overriding settings from the shared config

You can override settings from the shareable config by adding them directly into your eslint.config.mjs file after importing the shareable config. For example:

// eslint.config.mjs
import xolaLint from "@xola/jslint";

export default [
    ...xolaLint,
    // anything from here will override xolaLint
    {
        rules: {
            "no-unused-vars": "error",
        },
    },
];
