babel-preset-evergreen

library0.11.13jsnpmunverified

A Babel preset targeting modern JavaScript (ES2024) with automatic polyfill management via core-js. Current version 0.11.13 requires @babel/core ^7.29.0 and Node >=20.18.0. Unlike other presets like @babel/preset-env, evergreen focuses on evergreen browsers and offers flexible polyfill strategies (global or pure) with mini-program support. Release cadence is irregular; package is part of the best-shot ecosystem.

Verified usage

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

preset

✓ { "presets": ["evergreen"] }

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

In babel.config.json, the preset name is 'evergreen', not the full package name. Use 'evergreen' as the string in the presets array.

default

✓ import preset from 'babel-preset-evergreen';

✗ const preset = require('babel-preset-evergreen');

The package is ESM-only since v0.11.0. Use import syntax in JS/TS files if programmatically accessing the preset. For babel.config.json, use the string syntax.

polyfill option

✓ { "presets": [ ["evergreen", { "polyfill": { "usage": "global" } }] ] }

✗ { "presets": [ ["evergreen", { "useBuiltIns": "usage" }] ] }

The option is 'polyfill', not 'useBuiltIns'. It supports sub-options 'usage' (global|pure), 'include', 'exclude', and 'mini'. The default is false (no polyfill).

Configures Babel to transpile modern JS and add global polyfills for Chrome 60+.

// Install: npm install babel-preset-evergreen @babel/core --save-dev // babel.config.json { "targets": "chrome >= 60", "presets": [ [ "evergreen", { "polyfill": { "usage": "global" } } ] ] } // This config transforms modern JS and adds global polyfills for targets chrome >= 60.

Debug

Known issues

breakingRequires Node >=20.18.0 and @babel/core ^7.29.0. Older Node or Babel versions will fail.

fix

Update Node to >=20.18.0 and @babel/core to ^7.29.0.

affects: >=0.11.0

breakingESM-only since v0.11.0. CommonJS require() throws ERR_REQUIRE_ESM.

fix

Use import or dynamic import. For babel config, use string preset name 'evergreen', not require().

affects: >=0.11.0

deprecatedcore-js@2 is not supported; peg core-js@3 to avoid polyfill conflicts.

fix

Run: npm install core-js@3 --save-dev or pin in package.json.

affects: >=0.11.0

gotchaWhen using polyfill option, 'usage: global' adds polyfills globally, possibly impacting other code. 'pure' adds per-file imports.

fix

Choose 'global' for CLIs/libraries, 'pure' for applications to avoid global scope pollution.

affects: >=0.11.0

deprecatedThe 'polyfill.mini' option enables miniprogram presets which are rarely used and may be dropped.

fix

Avoid using polyfill.mini unless targeting miniprogram environments.

affects: >=0.11.0

Errors

Common errors & fixes

Error [ERR_REQUIRE_ESM]: require() of ES Module /path/to/babel-preset-evergreen/index.js from /path/to/project/babel.config.js not supported.

Using require() to load babel-preset-evergreen in babel.config.js (CommonJS) while package is ESM-only.

fix

Rename file to babel.config.mjs or use the string preset name: "presets": ["evergreen"].

Error: [BABEL] unknown preset: "babel-preset-evergreen"

Using the full package name (including 'babel-preset-') in the presets array instead of just 'evergreen'.

fix

Use "evergreen" as the preset name. Babel resolves 'evergreen' to 'babel-preset-evergreen'.

SyntaxError: Unexpected token 'export' (or modern feature not transpiled)

Missing or incorrect Babel configuration; preset not applied.

fix

Ensure babel.config.json exists with correct presets array and that Babel is run on the files.
