library6.23.1jsnpmunverified

Provides the regenerator runtime as a self-contained module for bundling with Rollup. Version 6.23.1 is the latest stable release. It replaces the default babel-runtime regenerator import with a local copy, avoiding external dependencies when using async/await and generators in libraries compiled with Rollup. Key differentiator: allows bundling regenerator runtime without requiring the full babel-runtime package, reducing bundle size and avoiding issues with Rollup's module resolution.

regeneratorRuntime

✓ import 'rollup-regenerator-runtime';

✗ import regeneratorRuntime from 'rollup-regenerator-runtime';

This module registers regeneratorRuntime globally as a side effect; no named or default export is provided.

default import

✓ import 'rollup-regenerator-runtime';

✗ const regeneratorRuntime = require('rollup-regenerator-runtime');

CommonJS require will return an empty object; use import for side effects.

CommonJS require

✓ require('rollup-regenerator-runtime');

✗ const regen = require('rollup-regenerator-runtime');

The module has no exports; use bare require() for side effects only.

Shows Babel configuration to replace babel-runtime regenerator with rollup-regenerator-runtime, and the import needed in the entry file.

// .babelrc { "plugins": [ "transform-regenerator", ["transform-runtime", { "helpers": false, "polyfill": false, "regenerator": true, "moduleName": "rollup-regenerator-runtime" }] ] } // In your entry file (must be imported before any async/await or generators) import 'rollup-regenerator-runtime';

Debug

Known issues

gotchaThe module must be imported (or required) as a side effect; it does not export anything. CommonJS require returns an empty object.

fix

Use `import 'rollup-regenerator-runtime';` or `require('rollup-regenerator-runtime');` without assigning to a variable.

affects: >=0.0.0

gotchaThis package only works when used as the regenerator moduleName in babel-plugin-transform-runtime. It does not function standalone.

fix

Ensure Babel configuration includes the plugins as shown in quickstart.

affects: >=0.0.0

Errors

Common errors & fixes

Module not found: Can't resolve 'regenerator-runtime' in ...

Babel transforms async/await but still imports from default 'regenerator-runtime' instead of 'rollup-regenerator-runtime'.

fix

Set `moduleName` to 'rollup-regenerator-runtime' in transform-runtime options and import 'rollup-regenerator-runtime' in your entry file.

regeneratorRuntime is not defined

The global regeneratorRuntime may not have been registered before async/await code runs.

fix

Ensure `import 'rollup-regenerator-runtime';` is placed at the top of your entry file, before any async functions.
