node-fetch related deps are not found when built

Current Behavior

I tried to create a little SDK using tsdx. I built the package and installed it on locally to test on React App. When i run the app it shows warning that:

warn  - ../.../node_modules/node-fetch/lib/index.js
Module not found: Can't resolve 'encoding' in '/.../node_modules/node-fetch/lib'

../.../node_modules/ws/lib/buffer-util.js
Module not found: Can't resolve 'bufferutil' in '/.../node_modules/ws/lib'

../.../node_modules/ws/lib/validation.js
Module not found: Can't resolve 'utf-8-validate' in '/.../node_modules/ws/lib'

Expected behavior

No warning or module found.

Suggested solution(s)

N/A
