npm
Configure npm to use the registry.
Setup
After scrutyn login, preview scrutyn setup npm --user, then run scrutyn setup npm --user --apply. For a project path, also preview and apply scrutyn setup npm --project. Project configuration contains a registry URL, not a token; each machine needs its own user setup.
For example, after scrutyn setup npm --project --name web --apply, the project .npmrc uses this registry line:
registry=https://registry.scrutyn.com/npm/p/web/
Remove conflicting @scope:registry overrides, environment overrides, and lockfile URLs pointing elsewhere: they can send installs outside the registry. Keep the user .npmrc private and out of version control. Use scrutyn doctor to check configuration.
