babel-preset-behance

23.0.0 verified Sat Apr 25 auth: no javascript maintenance

Babel preset for Behance projects, version 23.0.0. Configures babel-preset-env with default options: modules=false (for webpack >=2), useBuiltIns='entry', and adds Stage 3 loose transforms. Provides an `env` option to pass custom targets to babel-preset-env. Designed for internal use by Behance; not actively maintained for external users. Key differentiators: opinionated defaults suited for Behance's webpack-based build pipeline.

Common errors

error Error: Cannot find module 'babel-preset-behance' ↓

cause Preset not installed or not in node_modules

fix

Run npm install --save-dev babel-preset-behance

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

cause Using an incompatible Babel version (Babel 6 vs 7)

fix

Use Babel 6 or upgrade preset to Babel 7 version; check compatibility

Warnings

gotcha modules is false by default; if you need CommonJS modules for Node, set modules: 'commonjs' in env options. ↓

fix In .babelrc: {"presets": [["behance", {"env": {"modules": "commonjs"}}]]}

gotcha useBuiltIns is set to 'entry' by default; you must include import '@babel/polyfill' at entry point to avoid missing polyfills. ↓

fix Add import '@babel/polyfill' at the top of your entry file.

deprecated Stage 3 loose transforms are included by default, but Stage presets are deprecated in Babel 7+. ↓

fix Consider moving to @babel/preset-env with appropriate targets; avoid stage presets.
