babel-preset-es2040

library1.1.1jsnpmunverified

A Babel preset that enables a very small subset of ES6 features deemed essential by its authors, deliberately omitting most ES2015+ syntax. Version 1.1.1 is the latest and final release. It is an experimental, opinionated alternative to larger presets like babel-preset-env. Note: the name 'es2040' is ironic, indicating a minimal, possibly frivolous approach. The package is not actively maintained and is not recommended for new projects.

Verified usage

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

default export

✓ module.exports = require('babel-preset-es2040')

✗ import preset from 'babel-preset-es2040'

This preset is a CommonJS module. ESM import will fail unless using a bundler that handles CJS interop.

.babelrc config

✓ {"presets": ["es2040"]}

✗ {"presets": ["babel-preset-es2040"]}

Babel resolves the preset name 'es2040' to the package 'babel-preset-es2040'. Do not include the full package name in most cases.

Node API usage

✓ require('babel-core').transform('code', { presets: ['es2040'] })

✗ require('babel-core').transform('code', { presets: [require('babel-preset-es2040')] })

Passing the preset object directly is also valid but unnecessary. The string name works via Babel's resolution.

Install the preset, configure .babelrc to use it, and compile a JavaScript file with Babel CLI.

npm install --save-dev babel-preset-es2040 # .babelrc { "presets": ["es2040"] } # Then run babel on your files npx babel script.js --presets es2040

Debug

Known issues

deprecatedPackage is no longer maintained and may not work with modern Babel versions (v7+).

fix

Migrate to babel-preset-env or a custom preset with chosen plugins.

affects: >=1.0.0

breakingBabel 7 dropped support for presets without babel-preset- prefix in the name, requiring full package name in .babelrc.

fix

Use { "presets": ["babel-preset-es2040"] } or switch to a compatible preset.

affects: >=7.0.0

gotchaOnly a tiny subset of ES6 features are supported; most modern syntax will fail to compile.

fix

Check the list of supported plugins in the package source, or use a more comprehensive preset.

affects: all

gotchaPackage name includes 'es2040' but actually targets a subset of ES6 (ES2015), not ES2020.

fix

Do not assume it provides ES2020 features; refer to source for actual plugins.

affects: all

Errors

Common errors & fixes

Module not found: Can't resolve 'babel-preset-es2040' in ...

Babel cannot locate the preset if not installed or if the name resolution is incorrect.

fix

Run `npm install --save-dev babel-preset-es2040` and ensure it's in node_modules.

Error: [BABEL] unknown preset: es2040

Babel 7 requires the full package name if the default resolution fails.

fix

Change .babelrc to {"presets": ["babel-preset-es2040"]}.

SyntaxError: Unexpected token (something like import/const/arrow etc.)

The preset does not include the plugin for that feature.

fix

Use a different preset like babel-preset-env that supports the needed syntax.
