npm install --save-dev if-webpack-plugin
or
yarn add -D if-webpack-plugin
In your Webpack configuration in the plugins section:
// webpack.config.js
const IfPlugin = require('if-webpack-plugin')
const SuperCoolPlugin = require('super-cool-webpack-plugin')
const LessCoolPlugin = require('less-cool-webpack-plugin')
module.exports = {
// ...
plugins: [
new IfPlugin(
foo === 'bar',
new SuperCoolPlugin(),
new LessCoolPlugin()
)
]
}
The third argument can also be omitted in order to include an empty plugin, i.e. a plugin that simply does nothing:
// webpack.config.js
const IfPlugin = require('if-webpack-plugin')
const UglifyJsPlugin = require('uglifyjs-webpack-plugin')
module.exports = {
// ...
plugins: [
new IfPlugin(
process.env.NODE_ENV === 'production',
new UglifyJsPlugin()
)
]
}
