Example

Source package.json:

{
  "name": "test",
  "version": "1.0.0",
  "exports": {
    ".": {
      "import": "./dist/esm/index.js",
      "require": "./dist/index.js",
      "types": "./dist/ts/index.d.ts"
    },
    "./foo": {
      "import": "./dist/esm/foo/index.js",
      "require": "./dist/foo/index.js",
      "types": "./dist/ts/foo/index.d.ts"
    },
    "./bar": {
      "import": "./dist/esm/bar/index.js",
      "require": "./dist/bar/index.js",
      "types": "./dist/ts/bar/index.d.ts"
    },
    "./bar/baz": {
      "import": "./dist/esm/baz/index.js",
      "require": "./dist/baz/index.js",
      "types": "./dist/ts/baz/index.d.ts"
    }
  },
  "files": [
    "/dist"
  ]
}

Let's execure npx exports-fallback -gf. The result

├── package.json
|   bar
|   ├── baz
|   |   └── package.json
|   └── package.json
├── foo
|   └── package.json
└── .gitignore

Every created package.json will be something like

{
  "main": "../../dist/baz/index.js",
  "module": "../../dist/esm/baz/index.js",
  "types": "../../dist/ts/baz/index.d.ts",
  "typings": "../../dist/ts/baz/index.d.ts"
}

Some new lines will be added to the root package.json:

  "files": [
    "/dist",
    "foo",
    "bar"
  ]

Script also will create .gitignore (or change existed):

foo
bar
