@babel/helper-module-imports

addDefault

Adds a default import statement to the file. For example, it can add `import lodash from 'lodash';` to the code.

import { addDefault } from '@babel/helper-module-imports';
const path = /* ... */;
const imported = addDefault(path, 'lodash', { nameHint: 'lodash' });

addNamed

Adds a named import statement to the file. For example, it can add `import { map } from 'lodash';` to the code.

import { addNamed } from '@babel/helper-module-imports';
const path = /* ... */;
const imported = addNamed(path, 'map', 'lodash', { nameHint: 'map' });

addNamespace

Adds a namespace import statement to the file. For example, it can add `import * as lodash from 'lodash';` to the code.

import { addNamespace } from '@babel/helper-module-imports';
const path = /* ... */;
const imported = addNamespace(path, 'lodash', { nameHint: 'lodash' });

addSideEffect

Adds an import statement that will include a module for its side effects only, without importing any bindings. For example, it can add `import 'normalize.css';` to the code.

import { addSideEffect } from '@babel/helper-module-imports';
const path = /* ... */;
addSideEffect(path, 'normalize.css');
