Add types to package.json export about use-debounce

[xnimorz]

Hey @edu-bound
I'm sorry but I'm not sure I clearly understand the issue, may I ask for some examples, please?

Sure. In package.json, the exports field is as follows,

{
  "exports": {
    "./package.json": "./package.json",
    ".": {
      "import": "./esm/index.js",
      "require": "./lib/index.js"
    }
  }
}

Some tools recoginze the exports field and change their behavior based on its value. An example of such a tool is the ESLint plugin eslint-plugin-import-alias.

When a type not declared in the exports field is imported it, understandably, throws the following error,

Error [ERR_PACKAGE_PATH_NOT_EXPORTED]: Package subpath './lib/useDebouncedCallback' is not defined by "exports" in /home/aryzing/workspace/project/node_modules/use-debounce/package.json

Therefore the ask is to please include useful types (in particular the one I'm after is DebouncedState<T>) in the exports fields. To TS consumers, it makes sense to have them as part of the package's exposed API.

Eg, with the current structure of the published package,

{
  "exports": {
    "./package.json": "./package.json",
    ".": {
      "import": "./esm/index.js",
      "require": "./lib/index.js"
    },
    "./esm/useDebouncedCallback": {
      "import": "./esm/useDebouncedCallback.d.ts"
    }
  },
}
