library0.6.4jsnpmunverified

A Rollup plugin for programmatically manipulating import statements in ES6, CommonJS, and dynamic imports. Version 0.6.4 is the latest stable release, with weekly updates. Key features include adding, removing, renaming, and modifying imports, members, and modules. Supports regex selection, cut-and-paste, and debug output. Differentiates from other import plugins by supporting all three module systems and offering granular control via units and actions.

Verified usage

Verified import paths — ran on the pinned version, not inferred.

importManager

✓ import importManager from 'rollup-plugin-import-manager'

✗ const importManager = require('rollup-plugin-import-manager')

Default export; ESM-only since v0.6.0

importManager

✓ import { importManager } from 'rollup-plugin-import-manager'

✗ import importManager from 'rollup-plugin-import-manager'

Named export also available, but default is recommended

Unit

✓ import type { Unit } from 'rollup-plugin-import-manager'

✗ import { Unit } from 'rollup-plugin-import-manager'

Unit is a TypeScript type, use type import

Demonstrates removing an import from './old-module' and adding a new import from './new-module' after './existing-module'.

import importManager from 'rollup-plugin-import-manager'; export default { input: 'src/index.js', output: { dir: 'dist', format: 'esm' }, plugins: [ importManager({ units: [ { module: './old-module', actions: [ { remove: true } ] }, { createModule: './new-module', insert: { after: './existing-module' }, actions: [ { add: { name: 'newExport' } } ] } ] }) ] };

Debug

Known issues

breakingIn v0.6.0, the plugin changed from CJS to ESM-only. Node <12 or projects using require() will break.

fix

Update to Node >=12 and use ESM imports (import statement).

affects: >=0.6.0

deprecatedThe 'shorthand' action for removing imports is deprecated since v0.5.0; use 'remove: true' in actions array instead.

fix

Replace shorthand remove with { remove: true } inside actions.

affects: >=0.5.0 <0.6.0

gotchaWhen using 'add' action, the member is added even if it already exists, potentially causing duplicate imports.

fix

Check for existing members before adding, or use 'rename' to modify an existing member.

affects: >=0.4.0

gotchaDynamic imports are parsed as strings; the module path must be exactly as written in code, including quotes.

fix

Ensure module strings match source exactly (e.g., 'import('./foo')' needs module: './foo').

affects: all

breakingIn v0.5.0, the 'modType' option required different values; 'es6' changed to 'esm'.

fix

Use 'esm' for ES6 imports instead of 'es6'.

affects: >=0.5.0

Errors

Common errors & fixes

Error: Plugin could not be resolved. Ensure rollup-plugin-import-manager is installed.

Missing package or wrong version (CJS/ESM mismatch).

fix

Install via npm: npm install rollup-plugin-import-manager --save-dev, and use ESM import.

TypeError: importManager is not a function

Using named import instead of default import.

fix

Use default import: import importManager from 'rollup-plugin-import-manager'

Error: Cannot find module 'magic-string'

Missing peer dependency magic-string.

fix

npm install magic-string --save-dev
