The paths do not get replaced when the rootUrl and baseUrl in tsconfig are different

[eddielam1]

I have a tsconfig with rootDir set to . and baseUrl set to app. When I run tsc-alias, it generates invalid path can do not replace the imports. But when I set rootDir and baseUrl to the same path, tsc-alias works perfectly. How does the value of the rootDir affect the replacers? Do rootDir and baseUrl have to the same for it to work?

After some playing around. It seems like tsc-alias does not evaluate the rootDir in the tsconfig. And it causes it to creates invalid paths, and not replace the impors. For example, If I have the following settings:

{
  compilationOptions: {
    ...
    rootDir: ".",
    baseUrl: "app",
    paths: {
      "@/*": ["../assets/*"],
      "@utils/*": ["./utils/*"]
    }
  }
}

tsc-alias will throw error when it tries to replace the paths. Changing the tsconfig to following allows tsc-alias to work.

{
  compilationOptions: {
    ...
    rootDir: ".",
    baseUrl: ".",
    paths: {
      "@/*": ["./assets/*"],
      "@utils/*": ["./app/utils/*"]
    }
  }
}
