jscale

Super simple file-size checking utility that lets you check the file size of a given JavaScript file untransformed, gzipped, uglified, and uglified+gzipped. Works on any file if you skip uglification. (Uglification is also quite slow on large files.)

Installation

npm install -g jscale

Usage

On a file path:

jscale index.js

From a pipe:

cat index.js | jscale

You can uglify JS files by passing -u true or --uglify true. Don't do this on non-JS files - it won't work!

jscale index.js -u true
# or
cat index.js | jscale -u true

Example

I created this because I wanted to quickly measure the weight of a potential third party dependency. Here's it working:

> jscale js-client-sdk-v2/dist/owen.js
info fyi untransformed size: 95.71kB
info fyi gzipped size: 29.31kB
info fyi uglified size: 94.27kB
info fyi uglifiedAndGzipped size: 28.46kB

TODOs

Be able to pass custom uglify options to this, as the uglifier isn't super useful (but the gzipper is nice).
