es6-minifier

Embeds Terser (current standard es6 minification tool in the NPM ecosystem) in a crystal shard via a cross-platform pkg-powered binary that embeds Terser in a lightweight portable nodejs environment. No nodejs required.

Usage

Just install the shard and you can minify your ES6+ Javascript as follows:

require "es6-minifier"

Es6Minifier.minify!("const  something = 3;") # => "const something=3;"

Es6Minifier.minify!(["file1.js", "file2.js"])
# file1.js and file2.js are overwritten with a minified version of their contents

If a parsing or IO error occurs, Es6Minifier.minify! will throw an error.

Right now there are no configurable options however this could be easily added by passing JSON options to minify.js and adding a bit of code on the crystal side. Pull requests welcome!

Currently supports linux, macos, and alpine. Could easily support FreeBSD and Windows with a several line change.

Installation

Just add the following to yoour shard.yml:
