Is Lerna pushing packages to different repositories?

Sorry for the newbie question, but it seems I can’t find the answer to this question. I have a monorepo with Yarn workspaces and Lerna

/lerna.json
/package.json (with a github repo)
/packages/A
/packages/A/package.json (with a github repo)
/packages/B
/packages/B/package.json (with a github repo)
/packages/C
/packages/C/package.json (with a github repo)
/site
/site/package.json (with a github repo)

Then, my beliefs are that with Lerna I can develop the site and packages all together with ease, which is done with Yarn workspaces, and then npm-publish packages A, B and C and site separately. I have been able to do this, but, here is what I don’t understand:

Before publishing to npm, I expected Lerna to push the changes to each github repository, and to do it without publishing with lerna version.

But I cannot get this done. Then, is this supposed to work? can I git push changes of all packages to their respective repositories? Or this is precisely what is not being done in a monorepo?

If I want this, do I need to implement subtrees or something similar?

Cheers,

@TrejGun I’ve just changed my implementation for a more understandable approach based on https://github.com/johno/actions-push-subdirectories/blob/master/entrypoint.sh and https://github.com/gatsbyjs/gatsby/blob/8933ca9b3bf2c9b4fd580dd437d8695c3be705b7/scripts/clone-and-validate.sh

It that’s of interest for you
