}

Usage with Prettier

This is all you need on your .prettierrc file:

"eslint-config-superop/.prettierrc.js"

ESLint and Prettier both support ignore files, but they do not have an extend feature so you should copy and paste the following files inside your project folder:

• .eslintignore
• .prettierignore

Copy ignores to current folder:

cp -r node_modules/eslint-config-superop/.eslintignore .
cp -r node_modules/eslint-config-superop/.prettierignore .

Usage with EditorConfig

This package also goes well with EditorConfig, just copy and paste .editorconfig inside your project folder.

Copy EditorConfig to current folder:

cp -r node_modules/eslint-config-superop/.editorconfig .

Lint scripts

You might want to copy and paste the following scripts from our package.json:

• eslint
• prettier
• lint
• lint-fix

Working with VS Code

To fix your files make sure you have the VS Code ESLint extension installed.

Add a .vscode folder at the root of your project with this settings.json file.

The important parts are:

  "[javascript]": {
    "editor.defaultFormatter": "dbaeumer.vscode-eslint"
  },
  "[typescript]": {
    "editor.defaultFormatter": "dbaeumer.vscode-eslint"
  },

  "editor.codeActionsOnSave": {
    "source.fixAll.eslint": true
  },
