babel-plugin-transform-inline-imports-commonjs

library1.2.0jsnpmunverified

A Babel plugin (v1.2.0, last updated 2019) that transforms ES module imports into lazily loaded, memoized CommonJS requires, deferring require() calls until the imported identifier is actually referenced. Unlike the standard babel-plugin-transform-es2015-modules-commonjs, this avoids upfront I/O and execution costs for imported modules. Maintained by the author of babel-plugin-module-resolver, but now in maintenance mode as most projects have moved to @babel/preset-env or other bundlers. Supports options like excludeModules and excludeNodeBuiltins to skip lazy loading for specific modules or Node builtins. No TypeScript types, minimal breaking changes across versions.

Verified usage

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

default

✓ module.exports = require('babel-plugin-transform-inline-imports-commonjs')

✗ import plugin from 'babel-plugin-transform-inline-imports-commonjs'

This is a Babel plugin, not a runtime package. It should be listed in .babelrc or babel.config.js, not imported in code. Common mistake is to try to import it in source files.

babel-plugin-transform-inline-imports-commonjs

✓ // .babelrc { "plugins": ["transform-inline-imports-commonjs"] }

✗ // Incorrect path { "plugins": ["@babel/plugin-transform-inline-imports-commonjs"] }

The package name does not include the @babel/ scope. Use the exact name as published.

excludeModules

✓ // .babelrc { "plugins": [["transform-inline-imports-commonjs", { "excludeModules": ["atom"] }]] }

✗ // Typo in option name { "plugins": [["transform-inline-imports-commonjs", { "exclude": ["atom"] }]] }

Option is 'excludeModules', not 'exclude'. Available since v1.0.0.

Shows Babel plugin configuration with exclusion options and a sample import that gets lazily loaded.

// .babelrc { "plugins": [ ["transform-inline-imports-commonjs", { "excludeNodeBuiltins": true, "excludeModules": ["react"] }] ] } // index.js (will be transformed) import express from 'express'; const app = express(); export default app;

Debug

Known issues

deprecatedThis plugin is in maintenance mode; it has not been updated since Babel 6 era. For Babel 7+, consider using @babel/plugin-transform-modules-commonjs with lazy evaluation via other means.

fix

Migrate to @babel/preset-env or @babel/plugin-transform-modules-commonjs with babel-plugin-lazy-require or similar.

affects: >=1.0.0

breakingIn version 1.0.0, the option 'exclude' was renamed to 'excludeModules'.

fix

Use 'excludeModules' instead of 'exclude' in plugin options.

affects: <1.0.0

gotchaIf you use this plugin alongside @babel/plugin-transform-runtime, the lazy loading may conflict with runtime helpers.

fix

Order plugins correctly: transform-inline-imports-commonjs should come before transform-runtime in your plugin list.

affects: >=0.1.0

gotchaLazy loading can cause issues with circular dependencies because the require is deferred until the variable is used.

fix

Use the 'excludeModules' option to skip lazy loading for modules involved in circular dependencies.

affects: >=0.1.0

Errors

Common errors & fixes

Error: Plugin/Preset files are not allowed to export objects, only functions.

Using the plugin incorrectly with a bundler that doesn't support Babel 6-style plugins, or using a Babel 7 package with Babel 6.

fix

Ensure you are using Babel 6 with this plugin. For Babel 7, use a different module transformation plugin.

Cannot find module 'babel-plugin-transform-inline-imports-commonjs'

Package not installed or wrong name in .babelrc.

fix

Run: npm install --save-dev babel-plugin-transform-inline-imports-commonjs and verify the name in .babelrc.
