StackBlitz synchronization with github - upload to from StackBlitz to github

For those looking for a way to import an existing GitHub repo into Stackblitz, please read: https://stackblitz.com/docs#import-from-github.

You can run any public repo on Github by providing the username + repo name like so: stackblitz.com/github/{GH_USERNAME}/{REPO_NAME}

And you can also optionally specify a branch, tag, or commit: .../github/{GH_USERNAME}/{REPO_NAME}/tree/{TAG|BRANCH|COMMIT}

Just to add to the answer, you do have to save your code to see the "Connect Repository" option pop up. When you click "Connect Repository" then click on "import an existing repository". It doesn't look "clickable" but it is.

Syncing from Stackblitz to GitHub

Looks like you can synchronize your existing stackblitz-project with your github-account by:

1. logging into stackblitz
2. open a project you have write access
3. click on synchronization option on top left - a github-login page opens
4. fill in your gitlab credentials and grant stackblitz accessing github

Once you change something you can click Commit-Option on top to synchronize back to github - will only be available when step 4. successfully be done.
