beautify-with-words
beautify-with-words beautifies javascript and replaces variable names with unique "long-ish words". It uses UglifyJS2's beautifier, but uses a phonetic word generator to rename variables. This makes it easier less-hard to read unminified code and do things like search-and-replace.
Installation
With npm as a global package:
{sudo} npm install -g beautify-with-wordsUsage
beautify-with-words [input_file.js] [options]
beautify-with-words takes one file at a time – or, if no input file is specified, then input is read from STDIN.
- Use the
-o/--outputoption to specify an output file. By default, the output goes toSTDOUT; - Use the
-b/--beautifyto pass UglifyJS2 beautifier options; - And
-h/--helpfor help.
Reading from, and saving to, a file:
beautify-with-words backbone-min.js -o backbone-youre-beautiful-regardless.js
Send the output to STDOUT, and turn off syntax beautification but keep variable renaming:
beautify-with-words backbone-min.js -b beautify=false
Tell the beautifier to always insert brackets in if, for, do, while or with statements. Go here for more options.
beautify-with-words backbone-min.js -b bracketize=true

var beautifyWithWords = require('beautify-with-words');
var beautifiedCode = beautifyWithWords(code, options);
code is a string of the code you want to beautify. options is optional, and must be an object. It has a b property, which is an object of the options to be passed to UglifyJS2.
var fs = require('fs');
var beautifyWithWords = require('beautify-with-words');
var backboneSource = fs.readFileSync('backbone-min.js', { encoding: 'utf8' });
var beautified = beautifyWithWords(backboneSource, { b: { bracketize: true } });
console.log(beautified);
