Setup NPM prepublish minify script

Question

I want to setup a script that will minify my Javascript code before I publish it using NPM.

As far as I understand, this should be possible using this in package.json:

"scripts": {
    "prepublish": "somethingThatMinifies"
}

What tool is the best/most commonly used for minification in this situation?

Answer 1

Little bit late but hope it still helps someone (like myself, who got here from a Google search about "prepublish").

I believe uglifyjs is one of the most popular minification and compression tools.

You could use it like this:

"scripts" : {
  "prepublish" : "uglifyjs -o myfile.min.js myfile.js"
}

Just make sure to add uglify-js to your devDependencies.

See uglifyjs for options and more information on how it works. If your minification process gets too complex, you could create a Makefile and use something like:

"scripts" : {
  "prepublish" : "make minify"
}
