@fffddd-dfeeedd No, most likely they will not affect Google rankings. Any external links from NodeBB are automatically nofollow'd, and those bugs you've pointed out don't affect ranking of the page itself.
I'm not really sure what you're trying to do here - if you want to copy a repository to a local folder you should use git clone and not git checkout - the latter is used for switching branches and generally moving to a different version of a repository. However, got should not be used to install a plugin. NPM is the utility you're looking for. It supports two methods of authentication for GitHub private repositories - OAuth and SSH.
For OAuth you'll need to generate a personal access token (settings>developer settings>personal access tokens) with permission to read private repositories (just repository permissions if I remember correctly), and then go to the main NodeBB directory and use npm install git+https://<github_token>:[email protected]/NodeBB/nodebb-plugin-xxx.git
If you prefer to use SSH instead, follow the instructions here to generate the keys and add to your account, and then run in the main NodeBB folder npm install git+ssh://[email protected]/NodeBB/nodebb-plugin-xxx.git
I had never used Mongoose before but I know it is used for schema and validation. I was wondering though if anyone knew off chance if it could be added to NodeBB's database without it interfering with how it currently operates? I came across this backend administrative application called ForstAdmin and I was thinking about trying to see if I could add it into my current install. The application itself is made to integrate into an application you already have up and running, but that is under the assumption you are already have Mongoose and are using Express. I might spin up another board just to give it a go and see what happens, lol.
