Fails to resolve types with "moduleResolution": "bundler" in tsconfig

[dstaver]

Could not find a declaration file for module 'froebel/forward'. '/Users/daniel/testproject/node_modules/froebel/forward.mjs' implicitly has an 'any' type.
  There are types at '/Users/daniel/testproject/node_modules/froebel/forward.d.ts', but this result could not be resolved when respecting package.json "exports". The 'froebel' library may need to update its package.json or typings.

Adding a types property to every export in package.json solves it:

Same issue here.

In the mean time, you can force TypeScript to use the index.d.ts file, by adding the following to your TS compiler config.

{
  "compilerOptions": {
    ...YOUR_SETTINGS
    "paths": {
      ...YOUR_PATHS
      "froebel": ["./node_modules/froebel/index.d.ts"], 
    },
  },
}
