minify javascript in a stream using uglify-js

npm travis standard

npm install minify-stream

var minifyStream = require('minify-stream')
fs.createReadStream('app.js')
 .pipe(minifyStream())
 .pipe(fs.createWriteStream('app.min.js'))

Create a new minify stream. Write a Javascript file or bundle to it. Possible options are:

• uglify - An uglify module to use, defaults to terser. It must have an uglify-compatible minify() function.
• All other options are passed to the minify() function as the second parameter. See the terser docs for available options.

minify-stream adds inline source maps by default. Use exorcist to extract source maps from the output stream into a separate file. If you don't need source maps, pass the sourceMap: false option to disable them.

minifyStream({ sourceMap: false })
