How can npm install private GitHub repos along with their private dependencies?

I need to use npm to install a private GitHub repository that, in turn, depends on other private modules. I have explored several methods and forum posts, but nothing seems to work correctly. My approach involves running a command like:

npm install git+ssh://private.repo.url/username/mainProject.git

Additionally, my package configuration includes dependency entries such as:

"dependencies": {
    "moduleAlpha": "git+ssh://private.repo.url/username/moduleAlpha.git",
    "moduleBeta": "git+ssh://private.repo.url/username/moduleBeta.git"
}

What is the proper method to achieve this setup?

In my experience, dealing with private GitHub repositories and their private dependencies through npm requires careful attention to your SSH setup and npm configuration. I solved a similar problem by ensuring that every private repository was accessible via correctly managed SSH keys and by setting up a dedicated .npmrc file that included the necessary authentication tokens. It was important to keep the SSH config consistent to avoid permission issues and caching problems in npm. Once I streamlined the authentication process, npm installations became reliable even with nested private modules.

A successful approach I found involved streamlining SSH key usage and ensuring consistent device authentication across all repositories. I configured my SSH agent to remain active throughout the process and set up a dedicated .npmrc to reference private registries with proper credentials. In my workflow, using git+ssh URLs for both the main project and its dependencies worked best once all host addresses were correctly resolved. Keeping the configuration uniform prevented mismatches between keys and users, which often disrupts the installation of nested private modules.

i solved it by reworking my .npmrc using a token and keeping my ssh-agent running. oddly, a minor misconfiguration in git urls had been messing things up. after tightening auth, installs followed through smoothr with nested repos. give it a try!
