Wildcard imports are easier to write, but make it harder to pick out the specific functions or objects from a dependency that are used in a file.

import * from 'module';

// there is no clear way to tell if 
// `someFunction` has been imported
// from 'module'.
someFunction();

Therefore, it is recommended to explicit imports wherever possible.

NOTE: Some libraries do not expose themselves as ESModules. In cases like these, it is recommended to use a skipcq comment to suppress this issue.

Bad Practice

import * as axios from 'axios'
import * as Sentry from '@sentry/node'

try {
  const result = await axios.get();
  // ...
} catch (err) {
  Sentry.captureException(err);
}

Recommended

import axios from 'axios'
// skipcq: JS-C1003 - sentry does not expose itself as an ES Module.
import * as Sentry from '@sentry/node'

try {
  const result = await axios.get();
  // ...
} catch (err) {
  Sentry.captureException(err);
}
