(fix): don't treat @/ ~/ alias as external module

[rockmandash]

Current Behavior

Treating none relative import as external.

Desired Behavior

I know TSDX absolute import is under discussion right now.

But can we start supporting @/ and ~/ as an alias of srcDir?

It's widely used in Nuxt community, see documentation

Suggested Solution

Don't treat import path that startsWith @/ and ~/ as external.

So people can write their own absolute import plugin like this:

function rollupPluginAbsoluteImport() {
  return {
    name: "rollup-plugin-absolute-import",
    resolveId(source: string) {
      if (source.startsWith("@/") || source.startsWith("~/")) {
        return path.resolve(paths.appSrc, "." + source.slice(1, source.length));
      }
      return null;
    }
  };
}

Who does this impact? Who is this for?

All users who can't wait to use absolute import path

Describe alternatives you've considered

There is no way to use the absolute import path for TSDX right now I think.

I tried a lot of rollup plugins...

Additional context

Maybe release more often?

A few things:

1. This is a feature, not a bugfix
2. There is a way to do aliases with babel-plugin-module-resolver, see this HOWTO: HOWTOs #379 (comment)
3. I think I could get behind a default using @, though this might need support in Parcel and Storybook examples for consistency. ~ I think is very confusing since that refers to homedir in unix.
4. RE: frequency of releases: More frequent releases please! #512 . I think you already up-voted it
