Brunch plugin to turn latest ECMAScript standard code into vanilla ES5 with no runtime required.
npm install babel-brunchBrunch plugin using Babel to turn latest
ECMAScript standard code into vanilla ES5 with no runtime required.
All the .js files in your project will be run through the babel compiler,
except those it is configured to ignore, unless you use the pattern option.
Additionally, starting Brunch 2.7, babel-brunch will also compile NPM dependencies.
``
npm install --save-dev babel-brunch
babel-preset-env (a Babel preset that can automatically determine the plugins and polyfills you need based on your supported environments) is used by default.
The default behavior without options runs all transforms (behaves the same as babel-preset-latest).
Optionally, you can configure the preset for your needs:
`js`
module.exports.plugins = {
babel: {
presets: [['env', {
targets: {
browsers: ['last 2 versions', 'safari >= 7']
}
}]]
}
}
Read more about env's options.
Install a plugin:
`
npm install --save-dev babel-preset-react
Then, make sure Brunch sees it:
`js`
module.exports.plugins = {
// ...
babel: {
presets: ['env', 'react']
}
}
`js`
module.exports.plugins = {
// ...
babel: {
ignore: [
/^node_modules/,
'app/legacyES5Code/*/'
]
}
}
`js`
module.exports.plugins = {
// ...
babel: {
pattern: /\.(js|vue)$/ // By default, JS|JSX|ES6 are used.
}
}
Set Babel options in your Brunch
config (such as brunch-config.js) except for filename and sourceMap`
which are handled internally.
