- Rule ID: `tai-kun/type-literal-properties-newline`
- Auto-fix: Yes

Inserts a line break after `{` when a `type` literal has two or more members and the first member starts on the same line as the brace.

## Configuration [#configuration]

Add the rule to `lint.rules` in `vite.config.ts` to enable it.

```ts
"tai-kun/type-literal-properties-newline": "error",
```

## Examples [#examples]

### Invalid [#invalid]

```ts
type Options = { a: string; b: number };
```

### Valid [#valid]

```ts
type Options = {
  a: string;
  b: number;
};
```

## Notes [#notes]

- `interface` declarations are excluded because Oxfmt always prints them multiline.
- Use it together with `sort-type-members`.
