Deprecation Guide for Importing from @ember/string without @ember/string as a dependency
Importing from @ember/string without the @ember/string package as a
dependency is deprecated.
The @ember/string package is being moved to an addon @ember/string.
To add the package to your project:
ember install @ember/string
If you were importing htmlSafe or isHTMLSafe from @ember/string, please
import them from @ember/template instead. See
this deprecation guide for more information.
Note! As of May 19, 2023 there is a bug
in the implementation of the @ember/string deprecation. Adding @ember/string
to your project may not be enough to silence the deprecation. You may silence
the deprecation by using ember-cli-deprecation-workflow.
To upgrade to ember-source v5.0, ensure that @ember/string has been added
to your project, and even if you still see this deprecation warning on v4.x, imports from
@ember/string will continue to work and no longer display a deprecation warning
once on v5.x.
