Decent Mess Up

Want to understand my js? No way!

Demo

Playground

Input:


const str="abc";
function func(){
    const obj={};
    obj.property={
        key1:'value1',
        'key2':str,
        ['key'+3]:'value3'
    }
    console.log(obj);    
}
func();

Output:

const _a = 'vcb3aotkleyr21ugp';
const _b = 'bcktuovea2grp1y3l';
const _c = 'yecauop3rkbltg2v1';
const str = _a[4] + _b[0] + _a[1];
function func() {
    const _a2 = _b;
    const _b2 = _a;
    const _c2 = _c;

    const obj = {};
    obj[_a2[12] + _c2[8] + _c2[5] + _a2[12] + _b2[9] + _c2[8] + _b2[6] + _a2[14]] = {
        [_b2[7] + _b2[9] + _a2[14] + _b2[13]]: _c2[15] + _c2[3] + _a2[16] + _b2[14] + _c2[1] + _a2[13],
        [_a2[2] + _c2[1] + _b2[10] + _a2[9]]: str,
        [_c2[9] + _a2[7] + _a2[14] + 3]: _c2[15] + _c2[3] + _c2[11] + _b2[14] + _a2[7] + _a2[15]
    };
    console[_a2[16] + _c2[5] + _b2[15]](obj);
}
func();

Install

npm i -D decent-messup

Usage

Use it before babel and uglifying. Using it with uglifier is highly recommended.

const messup=require('decent-messup');
messup(yourcode[,options]);

Use with Webpack

module: {
    loaders: [{
        test: /\.jsx?$/,
        loader: 'decent-messup/loader',
        query: {
            headCnt:5,
            es6:true
        },
        },{
        test: /\.jsx?$/,
        loader: 'babel-loader',
        query: {
            presets: ['latest', 'stage-0'],
            plugins: []
        },
        }]
},

Use with Gulp

const transform = require('gulp-transform');
const messup = require('decent-messup');
gulp.task('quadruple', function() {
  return gulp.src('src/*.js')
    .pipe(transform(code => messup(code,{headCnt:5,es6:true})))
    .pipe(gulp.dest('dist'));
});

Options

The default options are:

{
    headCnt: 3,
    es6:false
}

headCnt

The count of string variables in each function scope.

headCnt=1:

var _a = '31olg2';
console[_a[3] + _a[2] + _a[4]](_a[1] + _a[5] + _a[0]);

headCnt=3:

var _a = 'l1go23';
var _b = '13gol2';
var _c = '23og1l';
console[_b[4] + _b[3] + _b[2]](_b[0] + _b[5] + _b[1]);

es6

Indicates if it should output es6 code.

Input:

a={b:'c'}

es6=false:

var _a = 'c';
var _b = 'c';
var _c = 'c';
a = { b: _c[0] };

es6=true:

const _a = 'cb';
const _b = 'bc';
const _c = 'bc';
a = { [_b[0]]: _b[1] };
