Library deprecated on npm
The npm registry marks the installed library, or the installed version, as deprecated.
What it means
A deprecated package will not get releases for future Angular majors. It may still work today, and the npm deprecation message usually points at the replacement.
How to fix it
Plan the replacement before it becomes a blocker (DIOP0201) on the next upgrade.
