Function: parseRootData()

parseRootData(): RootData

Retrieves the root data of the project.

This function reads the package.json file in the current working directory and determines the root path and type of the project.

  • If the package.json file is not found or cannot be parsed, it assumes the project is using CommonJS and the current working directory is used as the root

  • If the project type is specified as "commonjs" or "module" in the package.json, it uses the corresponding main or module file path as the root.

    • If there is no main or module then it uses the current working directory as the root, while retaining the matching CommonJS or ESM based on the type
  • If the main or module file path is not specified, it uses the current working directory as the root.

The following table shows how different situations resolve to different root data
