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
}
