Typescript types not resolving when using tsconfig with moduleResolution: "Bundler"

[jrouleau]

Could not find a declaration file for module 'tinykeys'. './node_modules/tinykeys/dist/tinykeys.module.js' implicitly has an 'any' type.
  There are types at './node_modules/tinykeys/dist/tinykeys.d.ts', but this result could not be resolved when respecting package.json "exports". The 'tinykeys' library may need to update its package.json or typings.ts(7016)

Here's what I found while researching this issue:
microsoft/TypeScript#52363

Perhaps somewhat related, types also cannot be resolved when using "moduleResolution": "node" apparently.

Could not find a declaration file for module 'tinykeys'. '/path/to/node_modules/tinykeys/dist/tinykeys.module.js' implicitly has an 'any' type.
There are types at '/path/to/node_modules/tinykeys/dist/tinykeys.d.ts', but this result could not be resolved under your current 'moduleResolution' setting. Consider updating to 'node16', 'nodenext', or 'bundler'.ts(7016)

Needs types entry in exports:

{
  "exports": {
    ".": {
      "types": "./dist/tinykeys.d.ts",
      "import": "./dist/tinykeys.module.js",
      "require": "./dist/tinykeys.js"
    }
  }
}

OK.. Saw the 2nd PR which got it right.. Currently using a fork just for this.

FYI, you can patch this locally with patch-package

Note: changes to package.json files are excluded by default so use --exclude 'nothing' when creating the patch. E.g. npx patch-package tinykeys --exclude 'nothing'

Here's our patches/tinykeys+3.0.0.patch file:
