JSON 模块

\JSON modules

import 可以引用 JSON 文件:

\JSON files can be referenced by import:

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

assert { type: 'json' } 语法是强制性的;见 导入断言。

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

导入的 JSON 只暴露一个 default 导出。不支持命名导出。在 CommonJS 缓存中创建缓存条目,以避免重复。如果 JSON 模块已经从同一路径导入,则在 CommonJS 中返回相同的对象。

\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.
