babel-preset-kyt

library1.1.21jsnpmunverified

An opinionated Babel preset for kyt, the NY Times frontend toolkit. Current stable version is 1.1.21 (last released May 2025). It provides a pre-configured Babel setup for React and TypeScript projects, supporting both ESM and CJS modules. Key differentiators: tightly integrated with kyt for zero-config transpilation, includes presets for environment-specific builds (browser, node), and handles module transforms. Alternatives like @babel/preset-env and @babel/preset-react require manual configuration.

Verified usage

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

default export

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

✗ import preset from 'babel-preset-kyt'

Preset is CommonJS; ESM import is not supported directly. Use require() or use .babelrc presets array.

preset in .babelrc

✓ {"presets": ["babel-preset-kyt"]}

✗ {"presets": ["kyt"]}

Use full package name to avoid resolution ambiguity.

preset with options

✓ {"presets": [["babel-preset-kyt", { "modules": false }]]}

✗ {"presets": ["babel-preset-kyt", { "modules": false }]}

Options must be in an array: [preset, options].

Configures babel-preset-kyt in .babelrc and babel.config.js with environment-specific targets.

// .babelrc { "presets": ["babel-preset-kyt"] } // Or in babel.config.js module.exports = { presets: ["babel-preset-kyt"], // optionally override env targets env: { browser: { presets: [["babel-preset-kyt", { targets: "> 0.25%, not dead" }]] }, node: { presets: [["babel-preset-kyt", { targets: { node: "current" } }]] } } }

Debug

Known issues

gotchaPreset is CommonJS only; ESM import will fail with 'require is not defined' error.

fix

Use require() or configure via .babelrc/babel.config.js.

affects: >=1.0.0

gotchaOptions must be passed as array elements: [preset, options]. Direct object after preset string is ignored.

fix

Use nested arrays: "presets": [["babel-preset-kyt", { ... }]]

affects: >=1.0.0

gotchaIf using TypeScript, ensure @babel/preset-typescript is installed separately.

fix

npm install @babel/preset-typescript --save-dev and add to presets array.

affects: >=1.0.0

Errors

Common errors & fixes

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

Missing package installation

fix

npm install babel-preset-kyt --save-dev

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

Using ESM import to load preset

fix

Use require() or configure via .babelrc/babel.config.js (CommonJS).

SyntaxError: Unexpected token import

Preset not applied; possibly missing configuration

fix

Verify .babelrc or babel.config.js includes 'babel-preset-kyt' in presets array.
