eslint-config-aurora

Standard JavaScript, but with opinionated changes.

Changed rules

| Rule | Old | New | Why | |----------|-----------|-----------|---------| |space-before-function-paren|['error', 'always']|['error',{'anonymous': 'always', 'named': 'never', 'asyncArrow': 'always' }]| Spacing before named function parenthesis is just unusual. |

Changes the function parenthesis spacing rule to disallow spaces for named functions but continue to require them for anonymous and asyncArrow functions.

function name(arg) { ... } // ✓ ok now, previously forced a space

| Rule | Old | New | Why | |----------|-----------|-----------|---------| |comma-dangle|['error', 'never']|['warn', 'multiline']| Trailing commas allow for quicker additions to lists from cold starts.

Changes the dangling comma rule to be a warning instead of an error and expect them on the last element or property which is on a different line of comma separated values.

var obj = {
  message: 'hello', // ✓ ok now, previously an error
}
