yeslint!

A sensible, modern collection of configuration files for ESLint that enforces beautiful code. It contains both rules to ensure correct code (e.g. enforce break statements in each switch case), and rules to make your code beautiful (e.g. adding a trailing comma to array items that start on a newline).

What's included

Currently, the 3 following configuration files are available:

• generic: generic ESLint configuration for all modern JavaScript runtimes.
• node: an extension on the generic config, with rules specific to Node.js.
• svelte: configuration for Svelte and JavaScript in browser environments.

Examples

Please see the examples directory for some examples. Files that start with wrong. contain many errors, and the fixed version of those files is in their correct. equivalent.

Installation

Install it together with ESLint using npm, pnpm, Yarn, or whatever package manager you like to use:

npm install --save-dev eslint yeslint

yarn add --dev eslint yeslint

pnpm add --save-dev eslint yeslint

Then, tell ESLint to extend this configuration. Add it either in .eslintrc.json, add it as the default export in .eslintrc.js, or add it in your package.json under the "eslintConfig" key.

Please consider the following example. You should replace <name> with the name of the configuration you want to use.

module.exports = {
  extends: './node_modules/yeslint/config/<name>.js',
};

Or add this to your package.json file:

"eslintConfig": {
  "extends": "./node_modules/yeslint/config/<name>.js"
}

After installing, run npx eslint . to lint your code for the first time, or use npx eslint --fix . to lint while automatically fixing all auto-fixable problems ESLint finds in your codebase.
