library1.1.0jsnpmunverified

ES2017 async/await transpiler backed by nodent-compiler. Stable v1.1.0, low release cadence. Compiles async functions into ES2016-compatible Promise chains. Differentiates from Babel by targeting strict native Promise behavior with minimal runtime overhead. CLI and programmatic APIs available.

Code

Verified usage

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

compileAsync

✓ import compileAsync from 'es-async'

✗ const compileAsync = require('es-async')

Default export via ESM. CJS also works in Node.

compileAsyncFromFile

✓ import compileAsyncFromFile from 'es-async/from-file'

✗ const compileAsyncFromFile = require('es-async/from-file')

Submodule for file-based compilation.

from-file

✓ import compileFromFile from 'es-async/from-file'

Direct import from subpath. Returns Promise.

Compile ES2017 async/await code to ES2016 using default import and String input.

const compileAsync = require('es-async'); const es2017Code = `async function foo() { return await bar; }`; const es2016Code = compileAsync(es2017Code); console.log(es2016Code);

esasync --version

Debug

Known issues

gotchacompiled output uses native Promises; ensure runtime supports Promise

fix

Polyfill Promise if targeting older environments.

affects: >=1.0.0

deprecatedrequire('es-async/from-file') returns a function, but future versions may change export shape

fix

Check documentation for new submodule exports.

affects: >=1.0.0

gotchaCode compiled by es-async may be larger than alternatives like Babel due to verbose Promise wrapping

fix

Consider minification after compilation.

affects: >=1.0.0

Errors

Common errors & fixes

TypeError: compileAsync is not a function

Importing incorrectly using named import instead of default

fix

Use: const compileAsync = require('es-async');

Cannot find module 'es-async/from-file'

Running in environment where subpath exports are not supported

fix

Use direct path: require('es-async/from-file') (Node >=12) or copy file.
