This is quite a popular library and I just can't get it to work, so a demo project could help many of us debug why it does not work in these cases.

There is a sandbox link in the readme. Is there something more you're looking for? https://codesandbox.io/s/6vowz0w2wz?expanddevtools=1&file=/src/index.js

Eliav2 commented 3 years ago

how did I miss that?

Eliav2 commented 3 years ago

but hey, why it doesn't show rerender of not pure components?

vzaidman commented 3 years ago

For not pure components, you. need to subscribe manually:

Component.whyDidYouRender = true;
