Yarn
Configure Yarn Classic or modern Yarn.
Setup
Yarn Classic reads npm configuration, but its compatibility with the user setup and project-path credentials has not yet been tested. Modern Yarn uses its own .yarnrc.yml; use the dashboard Setup guide for its host-bound credential and registry settings. There is no scrutyn setup yarn command.
For example, the modern Yarn project configuration below selects the web project path. Set up the matching project-path credential in your private user configuration using the dashboard guide; this file does not contain it.
npmRegistryServer: "https://registry.scrutyn.com/npm/p/web/"
Remove npmScopes or other scoped registry entries that point elsewhere. Keep authentication in your private user file, not the project. Existing lockfile URLs may still resolve from another host.
