and also manualy deleting npm package i still get
Requested version(1.0.0) already exists.
When trying to upload my library.
As stated in the Documentation,
You can only publish a specific version of a package once. This is an npm restriction to ensure that the contents of a published package version are always the same. As a result, you cannot:
Overwrite a package version by publishing it again to the repository
Remove a package or its version from the repository, and then publish a package with the same name and version number
Also mentioned in the Documentation,
After a package version is published, you cannot republish a package with the same name and version combination, even after deleting the version. This is an npm restriction to ensure that the contents of a published package version are always the same.
This is to ensure reproducible builds, and it is considered best practice to publish a newer patch instead of the same version once a version is deleted, which Artifact Registry supports. It is recommended that publishing a minor version update instead.
One more workaround is to create a new artifact registry and add all the intended packages to the new artifact registry to overcome the npm restriction mentioned above.
