uglify-es-loader

Uglify loader for webpack(fork from uglify-loader, using terser@3)

To install

---

``shell
npm i -D uglify-es-loader
`

Use Case

---
Webpack has UglifyJSPlugin that uglifies the output after bundling.
In the applications that depend on thirdparty libraries you may want to uglify with mangling only your application code but not the code that you don't control.

Example

---
Webpack 1
`js
module: {
loaders: [
{
// I want to uglify with mangling only app files, not thirdparty libs
test: /.\/app\/.\.js$/,
exclude: /.spec.js/, // excluding .spec files
loader: "uglify"
}
]
}
`

You can pass UglifyJS parameters via 'uglify-es-loader' property of webpack config.

`js
module: {
loaders: [
{
// I want to uglify with mangling only app files, not thirdparty libs
test: /.\/app\/.\.js$/,
exclude: /.spec.js/, // excluding .spec files
loader: "uglify"
}
]
},
'uglify-es-loader': {
mangle: false
}
`

Webpack 2
`js
module: {
rules: [
{
// I want to uglify with mangling only app files, not thirdparty libs
test: /.\/app\/.\.js$/,
exclude: /.spec.js/, // excluding .spec files
use: 'uglify-es-loader'
}
]
}
`

You can pass UglifyJS parameters via loader options.

`js
module: {
rules: [
{
// I want to uglify with mangling only app files, not thirdparty libs
test: /.\/app\/.\.js$/,
exclude: /.spec.js/, // excluding .spec files
use: {
loader: 'uglify-es-loader',
options: {
mangle: false
}
}
}
]
}
`

Enable sourceMap
`js
{
loader: 'uglify-es-loader',
options: {
enableSourceMap: true
}
}
`
