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 không nêu tên tệp nguồn, các bài kiểm thử hay các điểm vào. Hãy bắt đầu bằng cách xác định project-reference path resolution và xem xét mối quan hệ giữa rootDir, baseUrl với hành vi được đề xuất; công việc được xem là hoàn tất khi đã thống nhất và triển khai root-relative references, đồng thời giữ nguyên hành vi hiện có đối với các đường dẫn tương đối.
