Error with typescript and ESM

[ZachHaber]

When working with moduleResolution: nodeNext, the type definitions are interpreted by typescript as being commonjs. It doesn't seem to register the existence of the module property in the package.json.

So, the easiest way to resolve this to make TS happy is to add the exports property to the package.json and output a separate .d.ts file for the esmodule output.

  "exports":{
    ".":{
      "import": {
        "types":"./dist/index.d.mts",
        "default":"./dist/index.esm.js"
      },
      "require":{
        "types":"./dist/index.d.ts",
        "default":"./dist/index.cjs.js"
      }
    }
  },
