babel-preset-buildo

library0.1.1jsnpmunverified

A Babel preset that groups plugins and presets commonly used at buildo, including support for React and Node environments. Version 0.1.1 appears to be stable with no active development. It wraps babel-preset-env and conditionally includes React plugins based on the 'env' option. Compared to other presets like babel-preset-react-app, it is minimal and organization-specific, not recommended for general use.

Verified usage

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

default

✓ In .babelrc: { "presets": ["buildo"] }

✗ require('babel-preset-buildo') in babel.config.js

Used as a Babel preset in configuration files, not imported in code.

with options

✓ { "presets": [["buildo", { "env": "react" }]] }

✗ { "presets": ["buildo", { "env": "react" }] }

Options are passed as an array with preset name first, then options object.

environment detection

✓ Set BABEL_ENV or NODE_ENV to 'react' to automatically use react preset

✗ Setting env option in preset options while also using BABEL_ENV/react-preset separately

The preset's env option overrides automatic detection from BABEL_ENV.

Basic setup of babel-preset-buildo with React env and custom browser targets.

// Install npm install --save-dev babel-preset-buildo // .babelrc { "presets": [ ["buildo", { "env": "react", "targets": { "chrome": 52, "node": 4 } }] ] } // Run Babel npx babel src --out-dir lib

Known issues

deprecatedDepends on babel-preset-env which has been superseded by @babel/preset-env since Babel 7.

fix

Use @babel/preset-env directly or migrate to Babel 7+.

affects: >=0.0.0

gotchaThe package does not specify exact peer dependencies in older versions; install may fail without manually installing babel-preset-env.

fix

Ensure babel-preset-env is installed: npm install --save-dev babel-preset-env

affects: >=0.0.0

gotchaThe env option is case-sensitive; 'react' and 'node' are the only supported values. Unknown values may silently default to 'node'.

fix

Use exactly 'react' or 'node' for the env option.

affects: >=0.0.0

deprecatedThe transform-class-properties and transform-object-rest-spread plugins are included by default but are now part of @babel/preset-env's shipped proposals.

fix

Use @babel/preset-env with appropriate corejs version instead.

affects: >=0.0.0

Errors

Common errors & fixes

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

Missing peer dependency babel-preset-env.

fix

npm install --save-dev babel-preset-env

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

Using Babel 7+ which expects module formats that export functions, but babel-preset-buildo may export an object.

fix

Use Babel 6 or migrate to @babel/preset-env.

ReferenceError: regeneratorRuntime is not defined

Using async/generator functions without including babel-polyfill or @babel/polyfill.

fix

Add 'useBuiltIns': 'usage' option or import '@babel/polyfill'.
