Why is this an issue?

On the principle that clearer code is better code, you should explicitly import the things you want to use in a module. Using import * imports everything in the module and risks confusing maintainers. Similarly, export * from "module"; imports and then re-exports everything in the module and risks confusing not just maintainers but also the module’s users.

Code examples

Noncompliant code example

import * as Imported from "aModule";  // Noncompliant

Compliant solution

import {aType, aFunction} from "aModule";
