1. Install eslint-config-superop as a development dependecy of your project:

Usage

Shareable configs are designed to work with the extends feature of .eslintrc files. You can learn more about Shareable Configs on the official ESLint website.

This is all you need on your .eslintrc file:

{
  "extends": "eslint-config-superop"
}

And this string for the .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

You might also 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"
  },

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