@envsa/eslint-config

ESLint configuration for @envsa/shared-config.

Overview

It's a shared ESLint config, plus a command-line tool envsa-eslint to perform ESLint-related project initialization, linting, and fixing.

[!IMPORTANT]

You can use this package on its own, but it's recommended to use @envsa/shared-config instead for a single-dependency and single-package approach to linting and fixing your project.

This package is included as a dependency in @envsa/shared-config, which also automatically invokes the command line functionality in this package via its envsa command

Setup

To use just this ESLint config in isolation:

Install the .npmrc in your project root. This is required for correct PNPM behavior:
```
pnpm dlx @envsa/repo-config init
```

Add the package:

pnpm add -D @envsa/eslint-config
pnpm dlx @envsa/typescript-config init

Add the starter eslint.config.ts config file to your project root, and add any overrides you'd like:
```
pnpm exec envsa-eslint init
```

Usage

The ESLint binary should be picked up automatically by VS Code plugins.

You can call it directly, or use the script bundled with the config.

Integrate with your package.json scripts as you see fit, for example:

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

Notes

Regrettably the eslint-config init --location package option is not supported due to ESLint 9's deprecation of support for putting configuration in package.json. See ESLint discussion thread 18131.

Origins

This config is a heavily modified variation on Anthony Fu's @antfu/eslint-config. This package is a somewhat leaner approach intended to work with other tools wrapped behind a monolithic CLI instead of handling everything on its own. It mainly leverages the factory / type generation implementation from the original repo, which itself builds on Kevin Deng's @sxzz/eslint-config.
