unicorn/empty-brace-spaces

You can write an empty pair of braces as {}, { } or over two lines. This rule keeps {}, so empty objects, blocks, function bodies and class bodies look the same everywhere.

Braces with a comment in them aren't empty, so they're left alone.

--fix removes the whitespace.

Configure

Off by default. To turn it on:

[lint.rules]
"unicorn/empty-brace-spaces" = "error" # or "warn"

  // Nothing to clean up.
}
