Diagnostic Category: lint/correctness/noUndeclaredDependencies
Since: v1.6.0
Disallow the use of dependencies that aren’t specified in the package.json.
Indirect dependencies will trigger the rule because they aren’t declared in the package.json.
This means that if the package @org/foo has a dependency on lodash, and then you use
import "lodash" somewhere in your project, the rule will trigger a diagnostic for this import.
The rule ignores imports that are not valid package names.
This includes internal imports that start with # and @/ and imports with a protocol such as node:, bun:, jsr:, https:.
To ensure that Visual Studio Code uses relative imports when it automatically imports a variable,
you may set javascript.preferences.importModuleSpecifier and typescript.preferences.importModuleSpecifier to relative.
