babel-preset-es2020

library1.0.2jsnpmunverified

A Babel preset that includes only a subset of ES6 (ES2015) features, intentionally omitting most modern JavaScript additions. Version 1.0.2 is the latest and final release, with no active development since 2016. This package is a joke/experimental preset with very low download numbers. Key differentiator: it's a minimal, opinionated subset of ES6 for those who believe 'we can do without most of it.' Not recommended for real-world use.

Verified usage

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

default

✓ In .babelrc: "presets": ["es2020"] OR in code: module.exports = require('babel-preset-es2020')

✗ import pkg from 'babel-preset-es2020'

Babel presets are typically used as string names in config, not imported. If using programmatically, require() works due to CJS.

es2020

✓ Via Node API: require('babel-core').transform('code', { presets: [require('babel-preset-es2020')] })

✗ import { es2020 } from 'babel-preset-es2020'

Named export does not exist; the preset is exported as default (a function).

Shows how to use the preset in a .babelrc configuration file.

{ "presets": ["es2020"] }

Debug

Known issues

gotchaThis preset only includes a subset of ES6 features, not ES2020. It will not transform most modern JavaScript.

fix

Use @babel/preset-env for comprehensive and up-to-date transforms.

affects: >=1.0.0

deprecatedPackage is effectively abandoned with no releases since 2016. It uses old Babel 6 APIs.

fix

Do not use this preset; switch to @babel/preset-env.

affects: >=1.0.0

Errors

Common errors & fixes

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

Using an older version of Babel (6) that expects presets to be functions, but this preset is a plain object? Actually it exports a function, but this error may occur with newer Babel (7+) because the preset is not compatible.

fix

Use Babel 6 or switch to @babel/preset-env for Babel 7+.

Error: Cannot find module 'babel-preset-es2020'

Module not installed.

fix

Run npm install --save-dev babel-preset-es2020
