Ask questionsBug: React Context API is not working from custom NPM library

I have total of three npm packages:

  1. Custom Hook: custom hook wraps useContext
  2. Provider: uses custom hook to Provide Context
  3. Consumer: uses custom hook to Retrieve Context

If I have these components in a single app, everything works as expected. However, if I separate them to their own npm packages, the state is no longer retrievable by the consumer.

React version: 16.13.1

Steps To Reproduce

  1. Since it involves creating three different npm packages to repro, I've created a github repo that demonstrates the problem. Included all source code along with it. a) Repo:
  2. Kept the example extremely simple to keep the focus on the problem.

Link to code example:

<!-- Please provide a CodeSandbox (, a link to a repository on GitHub, or provide a minimal code example that reproduces the problem. You may provide a screenshot of the application if you think it is relevant to your bug report. Here are some tips for providing a minimal example: -->

The current behavior

The context state is not retrievable by the consumer.

The expected behavior

The context state should be retrievable by the consumer.

If you can't reproduce it using a single a file, it is a problem with your build configuration, not React
