Intellisense import suggestions - search index files only

Hi guys, in large codebases I often encounter following issue:

I work with React/TypeScript combo. If I export something from a file, it's visible to the entire project and Intellisense auto-import feature suggests me all functions/classes/... exported. It's overwhelming to list through all exports, especially in large projects, where different entities can have the same name. I would love to create some sort of hierarchy with use of index files. Auto-import would implicitly "see" only exports within the same folder or siblings of current folder (recursively) if they have exports declared in index file.

Example:

/src
   /module-alpha
      /components
         Alpha.tsx
         List.tsx
         Detail.tsx
         index.ts --> export {default} from './Alpha.tsx'
      /model
         utils.ts
         index.ts --> export * as Utils from './utils'
      ModuleAlpha.tsx
      index.ts --> export {default} from './ModuleAlpha.tsx'
   /module-beta
      /components
         Beta.tsx
         List.tsx
         Detail.tsx
         index.ts --> export {default} from './Beta.tsx'
      /model
         utils.ts
         index.ts --> export * as Utils from './utils'     
      ModuleBeta.tsx
      index.ts --> export {default} from './ModuleBeta.tsx'

If I am in file /src/module-alpha/components/Alpha.tsx and I type Detail, I want the auto-import to suggest me just Detail within the current folder. In this context I would be able to "see":

• List and Detail from current folder
• Utils from /model within this module
• ModuleAlpha
• ModuleBeta

In other words - folder will behave like a file. If you want the entity to be visible outside the folder, you would have to explicitly define the export in the index file (recursively). I hope that it's clear.

I don't want to change the ES6 module system, and we could still import the entity manually. I just want the intellisense to suggest me only relevant things.

Is this something that can be done?

首先检查现有的 IntelliSense 自动导入行为，以及 TypeScript 如何解析 index 文件中的导出。比较所述 module-alpha 和 module-beta 结构的建议。完成的标准是：建议仅限于递归声明的 index 文件导出，同时手动导入仍然可用。
