How to use default configuration?

1. Define scripts command in your package.json

It would be better if you define only files which you want to test. For example: the following command will use custom configuration file and check only files with extension .js only in folder ./core.

{
  "scripts": {
    "lint:js": "./node_modules/.bin/eslint --config eslint-config-lovely-code/silver --ext .js ./core"
  }
}

2. Run the command

yarn lint:js 

How to extend from default configuration?

1. Create .eslintrc in the project

touch .eslintrc

2. Extend from the configuration and write your own rules

Open created file for editing and write your code.

{
  "extends": "lovely-code/silver",
  "rules": {
    "no-console": "error"
  }
}

3. Define scripts command in your package.json

{
  "scripts": {
    "lint:js": "./node_modules/.bin/eslint --ext .js ./core"
  }
}

2. Run the command

yarn lint:js

Specify path to your webpack configuration file (where the resolve property is defined).

{
  "extends": "lovely-code/silver",
  "settings": {
    "import/resolver": {
      "webpack": {
        "config": "./webpack/webpack.config.js"
      }
    }
  }
}

How to fix some of the errors?

Eslint have an ability to fix some of errors which were found. To use this feature run yarn run lint:js -- --fix. Or add this command to the package.json.

{
  "scripts": {
    "lint:js": "./node_modules/.bin/eslint --ext .js ./core"
  }
}

Or, if you already defined lint:js you can use the following syntax.

{
  "scripts": {
    "lint:js": "...",
    "lint:fix": "yarn lint:js --fix"
  }
}
