"Organize Imports" should adjust specifiers based on preferences

从 TypeScript: Sort imports 命令以及 issue 中描述的 language server quick-fix 行为开始。跟踪 typescript.preferences.importModuleSpecifier、tsconfig baseUrl 和 paths 如何影响生成的 import specifier。当 import 已排序，并且符合条件的路径已根据这些偏好进行一致调整时，即视为完成。

⭐ Suggestion

I have a feature request for the language server / it's commands.

So I have a large project, and I have not changed tsconfig.json since the beginning of the time.
Now I "discovered" what baseUrl does, what paths does, and that there is an option in vscode - ```

"typescript.preferences.importModuleSpecifier": "non-relative", // | "project-relative" | "relative" | "shortest"`.

So I have a file, deep inside the source - which imports from a file, close to the root.
Before I added 'baseUrl' - it did

import { bar } from "../../../../../foo/bar";`

After adding "baseUrl": "./src/" in tsconfig - this could be written as

import { bar } from "foo/bar";`

bar();

If I delete the import, and go to the bar() to fix the import issue - it provides me quick fix -

• Add import from "foo/bar" if I have specified "typescript.preferences.importModuleSpecifier": "shortest" in settings., or
• Add import from "../../../../../foo/bar" if I have specified "typescript.preferences.importModuleSpecifier": "relative" in settings.

I really don't like those endless "../../../../../" so I would like to fix them. The only "tool" I have for now - is just to delete the import, and resolve those imports manually - so it gives me the best import paths given my settings and my tsconfig's "baseUrl" or "paths".

This is tedious. And it doesn't work where I have used import * as foo from [..].

In VSCode - there is a command Organize imports (I think this comes not from TypeScript?) (In my optionion - wasted effort. since it doesn't organize them, it just sorts them, but this is besides the point (it does not come from TypeScript))

But TypeScript does come with a command "Typescript: Sort imports"!

What I would want - after executing the command, it would not only sort the imports, but also - change the paths for those imports matching my preferences of settings.json "typescript.preferences.importModuleSpecifier" + tsconfig.json "baseUrl" and "paths".

Or it could be a new command - Typescript: Organize imports? (maybe not..)

This feature would help automatically shorten imports / make the satisfy project setting for a file.

💻 Use Cases

1. What do you want to use this for?
   To automatically organize imports
2. What shortcomings exist with current approaches?
   You have to manually go over each import and edit them one by one
3. What workarounds are you using in the meantime?
   Deleting the import and resolving them using quick fix.
