🤹 Usage
npm install -D @americanexpress/purgecss-loader
🎛️ API
Configure as follows:
module.exports = {
entry: {...},
output: {...},
module: {
rules: [
{
test: /\.css$/,
use: [
{
loader: 'css-loader',
options: {
modules: true,
localIdentName: '[name]__[local]___[hash:base64:5]',
},
},
{
loader: '@americanexpress/purgecss-loader',
options: {
paths: [path.join(somePath, 'src/**/*.{js,jsx}')],
safelist: [/:global$/],
},
},
],
},
],
},
}
You should use this with the css-loader
as seen above. However, it is not required that you use CSS modules. That is in
the example to express this loader's compatibility.
