#全局变量
注意
全局变量仅可读，不要修改此变量！
#FEDERATION
初始化完成后，会在全局注入 __FEDERATION__ 变量，该变量是一个对象，包含了当前应用的所有模块联邦信息。
#moduleInfo
TIP
推荐使用 chrome devtools 查看处理后的 moduleInfo。
记录当前应用所有的模块信息，根据此信息可以获取模块的依赖关系。
moduleInfo 结构是对象，其中 key 由 moduleName 和 moduleVersion 两部分组成： {moduleName}(:{moduleVersion})。
moduleName 是模块的名称，moduleVersion 是模块的版本或者 url 。
moduleVersion 仅在生产者模块中存在。
下面举例如何利用 moduleInfo 获取依赖关系，假设有下列的 moduleInfo：
moduleInfo

}在上述示例中，moduleInfo 包含了 5 个模块的信息，其中 manifest_host 后面没带有版本号，说明它是一个消费者模块。
manifest_host 中的 remotesInfo 字段记录了它依赖的所有生产者模块的信息，对应的 matchedVersion 字段记录了它匹配到的版本或者 url 。
可以通过消费者 remotesInfo 字段中的 key + matchedVersion 来获取对应的生产者模块信息，比如 webpack_provider:http://localhost:3009/mf-manifest.json 。
#version
仅存在于生产者，消费者该值为空字符串
当前模块的版本或者 url。
#buildVersion
当前模块的构建版本，通常取值于 package.json 中的 version 字段。
#globalName
仅存在于生产者
当前生产者模块的全局变量名称，可以通过 globalThis[globalName] 获取生产者的 container，通常取值于 package.json 中的 name 字段。
#publicPath
当前模块的 publicPath。
#getPublicPath
该字段和
publicPath互斥
当前模块的 getPublicPath，通过 new Function(getPublicPath)() 调用获取最终的 publicPath。
#ssrPublicPath
当前模块的 server 文件的 publicPath。
#remoteEntry
仅存在于生产者
当前生产者模块的入口文件名称。
#remoteEntryType
仅存在于生产者
当前生产者模块的入口文件类型。
#remoteTypesZip
仅存在于生产者
当前生产者模块的类型声明文件压缩包名称。
#remoteTypesAPI
仅存在于生产者
当前生产者模块的类型 API 声明文件名称。
#shared
当前模块依赖的所有共享模块信息。类型定义如下：
type Shared = Array<{
sharedName: string;
version?: string;
assets: {
js: {
sync: string[];
async: string[];
};
css: {
sync: string[];
async: string[];
};
};
}>;#modules
仅存在于生产者
当前模块导出的所有模块信息。类型定义如下：
type Modules = Array<{
moduleName: string;
modulePath: string;
assets: {
js: {
sync: string[];
async: string[];
};
css: {
sync: string[];
async: string[];
};
};
}>;#prefetchInterface
仅存在于生产者
当前模块是否开启了预加载。
#SHARE
当前已注册（加载）的所有共享模块信息，类型定义如下：
Type declaration
type GlobalShareScopeMap = {
[instanceName: string]: {
[scope: string]: {
[pkgName: string]: {
[sharedVersion: string]: {
version: string;
get: (() => () => Module) | (() => Promise<() => Module>);
shareConfig: {
singleton?: boolean;
requiredVersion: false | string;
eager?: boolean;
strictVersion?: boolean;
layer?: string | null;
}
scope: Array<string>;
useIn: Array<string>;
from: string;
deps: Array<string>;
lib?: () => Module;
loaded?: boolean;
loading?: null | Promise<any>;
// compatibility with previous shared
eager?: boolean;
/**
* @deprecated set in initOptions.shareStrategy instead
*/
strategy: 'version-first' | 'loaded-first';
}
};
};
};
};我们可以通过 __SHARE__ 来查询指定的 shared 加载情况，比如存在下列的 __SHARE__ ：
__SHARE__

}
在上述的数据中，可以看到 manifest_host 和 app1 两个模块的共享模块信息。 其中 react 总共只有 18.3.1 一个版本。
查看 __SHARE__["app1:0.1.94"].default.react["18.3.1"] 可以看到 react 模块的信息，发现 loaded 为 true ，说明 react 模块已经加载完成。
另外 from 字段为 webpack_provider ，说明 react 模块是由 webpack_provider 模块提供的。
再看 useIn 字段，可以看到 useIn 字段中包含了 webpack_provider 和 app1 两个模块，说明 react 模块被 webpack_provider 和 app1 两个模块使用了。
#INSTANCES
当前已加载的 MF 实例。
