Resolve project references from root

Project reference root resolve.

Suggestion

Resolve project reference paths from root directory of a mono repository.

Use Cases

We have a large mono-repository with 1000s of sub-packages we want to convert to TS projects. Currently the references between them must be defined as relative paths, leading to configuration like:

  "references": [
    {
      "path": "../../../base"
    },
    {
      "path": "../colors"
    },
    {
      "path": "../device_capabilities"
    }
  ],

Which is:

• Hard to read and reason about
• Creates noisy diffs when moving packages

Ideally project references could be resolved from the root of the mono-repo project, e.g. rootDir or baseUrl options.

E.g.:

  "references": [
    {
      "path": "base"
    },
    {
      "path": "ui/base/colors"
    },
    {
      "path": "ui/base/device_capabilities"
    }
  ],

Checklist

My suggestion meets these guidelines:

• This wouldn't be a breaking change in existing TypeScript/JavaScript code
• This wouldn't change the runtime behavior of existing JavaScript code
• This could be implemented without emitting different JS based on the types of the expressions
• This isn't a runtime feature (e.g. library functionality, non-ECMAScript syntax with JavaScript output, etc.)
• This feature would agree with the rest of TypeScript's Design Goals.

Issue にはソースファイル、テスト、エントリーポイントが記載されていません。まず project-reference path resolution の場所を特定し、rootDir と baseUrl が提案された動作とどのように関係するかを確認してください。root-relative references に合意して実装し、既存の相対パスの動作を維持できれば完了です。
