The same rules on every framework
Current framework releases, tests that ship with the feature, zero warnings at the end of every change, dependencies kept up to date and security advisories treated as unconditional upgrades.
Angular and React are covered on the front-end page, ASP.NET Core on the .NET page, NestJS on the Node.js page and Tauri on the desktop page. A framework without a page of its own is work we take on all the same.
