object-curly-spacing

在大括号内强制保持一致的间距

一些该规则报告的问题可以通过 --fix 命令行选项 自动修复

虽然格式偏好是非常个人化的，但在以下情况下，许多样式指南要求或不允许大括号之间有空格：

// simple object literals
var obj = { foo: "bar" };

// nested object literals
var obj = { foo: { zoo: "bar" } };

// destructuring assignment (EcmaScript 6)
var { x, y } = y;

// import/export declarations (EcmaScript 6)
import { foo } from "bar";
export { foo };

规则详情

此规则强制在对象字面量、解构赋值和导入/导出说明符的大括号内保持一致的间距。

选项

该规则有两个选项，一个字符串选项和一个对象选项。
