@fledra/eslint-config

One opinionated config for ESLint.

This config is a refactored/modified version of Anthony Fu's ESLint config. I will not copy every change from his config but I might occasionally yoink the ones I like.

• ESLint Flat config format
• Respects .gitignore by default
• Code style: Minimal for reading, stable for diff, consistent... enough.
  • Using ESLint Stylistic
  • Dangling commas
  • Single quotes
  • With semi

Usage

Install

First install eslint and this config:

pnpm i -D eslint @fledra/eslint-config

And create eslint.config.mjs in your project root:

// eslint.config.mjs
import fledra from '@fledra/eslint-config';

export default fledra();

Add script for package.json

For example:

{
  "scripts": {
    "lint": "eslint",
    "lint:fix": "eslint --fix"
  }
}

Customization

I followed Anthony's config for the most part so configuration options are pretty much the same. Check out customization section of his config for more info.

Important notes about configuration

• type key does not exist in the configuration object

Plugins Renaming

I thought I did not want any plugin renaming at first but only kept the original name of @typescript-eslint, which was confusing.

From version 2.0.0 onwards plugin renaming is enabled by default.

| New Prefix | Original Prefix | Source Plugin | | ---------- | ---------------------- | ------------------------------------------------------------------------------------------ | | import/* | import-lite/* | eslint-plugin-import-lite | | node/* | n/* | eslint-plugin-n | | yaml/* | yml/* | eslint-plugin-yml | | ts/* | @typescript-eslint/* | @typescript-eslint/eslint-plugin | | style/* | @stylistic/* | @stylistic/eslint-plugin |

When you want to override rules, or disable them inline, you need to use the new prefix:

-// eslint-disable-next-line @typescript-eslint/consistent-type-definitions
+// eslint-disable-next-line ts/consistent-type-definitions
type foo = { bar: 2 }

Change back to original prefix

If you really want to use the original prefix, you can revert the plugin renaming by:

import fledra from '@fledra/eslint-config';

export default fledra()
  .renamePlugins({
    ts: '@typescript-eslint',
    yaml: 'yml',
    node: 'n'
    // ...
  });
