Installation

npm i --save-dev @schoero/eslint-config

If you use npm < 7, you need to install the peer dependencies manually.

Usage

Create a .eslintrc.json with the following content:

{
  "extends": "@schoero"
}

Config

It is also recommended to create a .eslintignore file with the following content:

node_modules
!/.vscode
!/.github

VSCode integration

For automatic code formatting on save, install the ESLint extension.

To recommend the extension in your repository create a .vscode/extensions.json with the following content:

{
  "recommendations": [
    "dbaeumer.vscode-eslint"
  ]
}

To configure the extension properly, create a .vscode/settings.json with the following content:

{
  "[javascript]": {
    "editor.defaultFormatter": "dbaeumer.vscode-eslint"
  },
  "[json]": {
    "editor.defaultFormatter": "dbaeumer.vscode-eslint"
  },
  "[json5]": {
    "editor.defaultFormatter": "dbaeumer.vscode-eslint"
  },
  "[jsonc]": {
    "editor.defaultFormatter": "dbaeumer.vscode-eslint"
  },
  "[typescript]": {
    "editor.defaultFormatter": "dbaeumer.vscode-eslint"
  },
  "editor.codeActionsOnSave": {
    "source.fixAll.eslint": true,
    "source.organizeImports": false
  },
  "editor.formatOnSave": false,
  "eslint.validate": ["javascript", "typescript", "json", "jsonc", "json5", "yaml"],
  "prettier.enable": false
}

If you want to have linting scripts, you can use something like this in the package.json:

{
  "scripts": {
    "lint": "node_modules/.bin/eslint --ext .ts,.tsx,.js,.jsx,.json,.jsonc,.yml ./",
    "lint:ci": "npm run lint -- --max-warnings 0",
    "lint:fix": "npm run lint -- --fix"
  }
}
