JSON 模块

🌐 JSON modules

JSON 文件可以通过 import 引用：

🌐 JSON files can be referenced by import:

import packageConfig from './package.json' assert { type: 'json' }; 拷贝

assert { type: 'json' } 语法是必须的；见 导入断言。

🌐 The assert { type: 'json' } syntax is mandatory; see Import Assertions.

导入的 JSON 只暴露了 default 导出。不支持命名导出。为了避免重复，会在 CommonJS 缓存中创建一个缓存项。如果 JSON 模块已从相同路径导入，CommonJS 会返回同一个对象。

🌐 The imported JSON only exposes a default export. There is no support for named exports. A cache entry is created in the CommonJS cache to avoid duplication. The same object is returned in CommonJS if the JSON module has already been imported from the same path.
