rollup-plugin-async

library1.2.0jsnpmunverified

Rollup plugin that transforms async/await functions into generator functions during bundling using async-to-gen. Current stable version 1.2.0, last released circa 2017. Low release cadence. Differentiator: enables async/await in environments without native support by converting to generators at build time. Alternative to Babel's async-to-generator transform with tighter Rollup integration. Depends on async-to-gen (v1.2.0+). No longer actively maintained; users should consider @rollup/plugin-babel with @babel/plugin-transform-async-to-generator.

Verified usage

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

default

✓ import async from 'rollup-plugin-async'

✗ const async = require('rollup-plugin-async')

CommonJS with require works but the package does not have typed exports. Default export is a factory function.

default

✓ const async = require('rollup-plugin-async')

CommonJS require is supported. For ESM use import.

async

✓ import async from 'rollup-plugin-async'

✗ import { async } from 'rollup-plugin-async'

The package exports a single default function. Named import will not work.

Shows how to use rollup-plugin-async in a Rollup config to transform async functions in input.js.

import { rollup } from 'rollup'; import async from 'rollup-plugin-async'; rollup({ input: 'input.js', plugins: [async()] }).then(bundle => bundle.write({ file: 'output.js', format: 'iife' }));

Debug

Known issues

deprecatedPackage is no longer actively maintained. Use @rollup/plugin-babel with @babel/plugin-transform-async-to-generator instead.

fix

Replace with @rollup/plugin-babel configuration.

affects: >=1.0.0

gotchaAsync-to-gen may not support all modern async/await syntax variants (e.g., top-level await, for-await-of).

fix

Test with your specific async patterns. Consider migrating to Babel if issues arise.

affects: >=1.0.0

breakingVersion 1.2.0 updated async-to-gen to 1.2.0 with proper for-await-of loop support. Older versions may fail on for-await-of.

fix

Upgrade to version 1.2.0 or later.

affects: <1.2.0

Errors

Common errors & fixes

Cannot find module 'rollup-plugin-async'

Package not installed or not in node_modules.

fix

Run `npm install rollup-plugin-async --save-dev`.

TypeError: async is not a function

Importing the default export incorrectly as a named import or calling require without parentheses.

fix

Use `const async = require('rollup-plugin-async');` then call `async()`.

Error: Cannot find module 'async-to-gen'

Missing dependency async-to-gen (should be installed automatically but may not be in some setups).

fix

Run `npm install async-to-gen` or check your package-lock.
