babel-preset-wtw-im

library2.5.0jsnpmunverified

Babel preset for Willis Towers Watson Individual Marketplace, version 2.5.0. It bundles babel-preset-react, babel-preset-env, and plugins for lodash, format-message (extract and transform), and styled-components. Release cadence is low, appears to be internal use. Differentiator: opinionated preset tailored for WTW's React + i18n stack with format-message integration.

Verified usage

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

default

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

✗ import preset from 'babel-preset-wtw-im'

Preset is CommonJS, use require or reference in .babelrc

babel-preset-wtw-im

✓ In .babelrc: {"presets": ["wtw-im"]}

✗ {"presets": ["babel-preset-wtw-im"]}

Babel automatically resolves 'wtw-im' prefix; full name works but is unconventional.

options

✓ {"presets": [["wtw-im", { "react": false }]]}

✗ {"presets": ["wtw-im", { "react": false }]}

Options must be in nested array: [[preset, options]] not [preset, options]

Shows minimal .babelrc configuration using wtw-im preset with env targeting, react enabled, and styled-components options.

// .babelrc { "presets": [ ["wtw-im", { "env": { "targets": { "browsers": "> 1%" } }, "react": true, "styledComponents": { "ssr": false, "displayName": false }, "extractFormatMessage": false, "transformFormatMessage": { "inline": false } }] ] } // Then run: npx babel src --out-dir lib

Debug

fix

Use correct Babel preset options format: "presets": [["wtw-im", {...}]]

affects: >=2.0

gotchaPreset name 'wtw-im' (short form) is required, full 'babel-preset-wtw-im' may not work if Babel cannot resolve

fix

Use 'wtw-im' in presets array: "presets": ["wtw-im"]

affects: >=1.0

deprecatedbabel-preset-env is deprecated in favor of @babel/preset-env for Babel 7

fix

Upgrade to Babel 7 and use @babel/preset-env; this preset is for Babel 6

affects: >=2.0

gotchaIf using Node API, require the preset: require('babel-preset-wtw-im') and use in presets array

fix

Preset is CommonJS, use require() not import

affects: >=1.0

deprecatedbabel-core is version 6.x, not compatible with Babel 7

fix

For Babel 7, use @babel/core and @babel/preset-env etc.; this preset is for Babel 6 ecosystem

affects: >=2.0
