add support for webpack alias

Cannot detect the imported file if a project not use relative path import.

For example, use babel-plugin-module-resolver:

// .babelrc
{
  "plugins": [
    [ "module-resolver", {
       "alias": {
          "@": "./src"
        }
     }]
  ]
}

or use webpack resolve. alias

module.exports = {
  //...
  resolve: {
    alias: {
      '@': path.resolve(__dirname, 'src')
    }
  }
};

Hey @smeijer, thanks for your reply!

What I mean is to allow resolutions to be set on a per-entry basis. So in your example, maybe entry[0] would need to resolve our-utils-platform to our-utils-node and in entry[1] would need to resolve our-utils-platform to our-utils-web.

It seems like unimported makes a configuration like that of its own behind the scenes that looks like below, and it would be great if we could set the same type of config from the .unimportedrc.json

"entryFiles": [
    {
      "file": "src/main.ts",
      "aliases": {
        "our-utils-platform": "our-utils-node
      },
      "extensions": [ ".js", ".ts", ".tsx" ]
    },
    {
      "file": "src/pages/**/*.{js,ts}",
      "aliases": {
        "our-utils-platform": "our-utils-web
      },
      "extensions": [ ".js", ".ts", ".tsx" ]
    },

Does that explanation make sense? Thanks again for your hard work and for your reply!

Hi @Slapbox , it is possible to specify entryFiles via the config file. Does that help?

{
  "entry": ["src/main.ts", "src/pages/**/*.{js,ts}"],
}
