🛠 Installation

⚠️ ⚠️ ⚠️ This config was designed for use with ESLint version >=8.0.0 <=8.22.0 and has not been tested with the new flat config ESLint 9

1. Install ESLint if you haven't already

npm:

npm i eslint@8.22.0 --save-dev

yarn:

yarn add eslint@8.22.0 -D

2. Install prettier if you haven't already

npm:

npm i prettier --save-dev

yarn:

yarn add prettier -D

3. Install package

npm:

npm install @garvae/eslint-config-garvae eslint-plugin-typescript-sort-keys@3.2.0 eslint-plugin-unused-imports@3.2.0 --save-dev 

yarn:

yarn add -D @garvae/eslint-config-garvae eslint-plugin-typescript-sort-keys@3.2.0 eslint-plugin-unused-imports@3.2.0

4. Add the eslint-config-garvae to the ESLint config

{
  "extends": [ "@garvae/eslint-config-garvae" ]
}

If you don't have a babel config, then add the path to the on included in this library the ESLint config:

{
  "overrides": [
    {
      "files": [
        "*.js",
        "*.jsx"
      ],
      "parserOptions": {
        "babelOptions": {
          "configFile": "./node_modules/@garvae/eslint-config-garvae/babel.config.js"
        }
      }
    }
  ]
}

If you already have your own babel config, then check it includes (and you have installed) presets:

// your babel.config.js
module.exports = {
    "presets": [
        "@babel/preset-env",
        "@babel/preset-react",
        "@babel/preset-typescript",
    ]
}

It's also required to add the path to your tsconfig.json into next sections:

{
  "overrides": [
    {
      "files": [ "*.ts", "*.tsx" ],
      "parserOptions": {
        "project": "tsconfig.json"
      },
      "settings": {
        "import/resolver": {
          "typescript": {
            "project": "tsconfig.json"
          }
        }
      }
    }
  ]
}

5. Feature Sliced Design

You can add config of Feature Sliced Design:

{
  "overrides": [
    {
      "files": [ "*.ts", "*.tsx", "*.js", "*.jsx" ],
      "extends": [ "@feature-sliced" ]
    }
  ]
}

⚠️ 🛠 Known installation issues

It is challenging to combine the work of many libraries with different versions. Today ESLint version 9 has an updated flat config and many plugins have already changed their configuration to support this update. However, the eslint-config-garvae library dependencies have been tested in the exact combination of versions listed in below. If you have newer versions of these libraries installed, the functionality of ESLint is not guaranteed.

    "jsonc-eslint-parser": "2.4.0",
    "prettier": "3.3.2",

  }

There is already known issue with popular libraries:

{
  "@typescript-eslint/eslint-plugin": "^6.14.0",
  "@typescript-eslint/parser": "^6.14.0"
}

Working versions:

{
  "@typescript-eslint/eslint-plugin": "5.0.0",
  "@typescript-eslint/parser": "5.0.0"
}

And maybe up to

{
  "@typescript-eslint/eslint-plugin": "5.62.0",
  "@typescript-eslint/parser": "5.62.0"
}

So if you have versions newer than listed above, the possible solution:

1. Uninstall newer versions and eslint-config-garvae library using CLI
2. Reinstall eslint-config-garvae library
