How to migrate a proxy NPM repository in Nexus 3?

Question

I have a Nexus 3 installation with these NPM repos defined:

• npm-all (group)
• npm-internal (hosted)
• npmjs-org (proxy)

I would like to be able to populate the npm proxy repository on an Internet connected machine, and then migrate it to a Nexus Server running on a disconnected machine. Nexus 3 has a Task to backup/restore the entire underlying Orient database, but I can't find a way to do it for a specific repository. My goal is to have a npm proxy repo that's populated with NPM packages I need, in an offline environment.

Answer 1

As far as I know there is no way to do this with any built in mechanism. Your best bet is to publish all packages you need to a hosted repository or alternatively just have the proxy repo and server connected to the internet during provisioning but take it offline afterwards.

Answer 2

You can use this npm tool.

Using this tool download the artifacts from the repositories and upload them in the offline server
