gulp-javascript-obfuscator

Gulp plugin for javascript-obfuscator

Installation

Install the package with npm:

$ npm install --save gulp-javascript-obfuscator

Usage

const gulp = require('gulp');
const javascriptObfuscator = require('gulp-javascript-obfuscator');

gulp.src('file.js')
    .pipe(javascriptObfuscator())
    .pipe(gulp.dest('dist'));

Options

Pass any options available in the obfuscator

gulp.src('file.js')
    .pipe(javascriptObfuscator({
        compact: true
    }))
    .pipe(gulp.dest('dist'));

The only exception is obfuscator's sourceMap option which must not be set, as it will be handled automatically when using gulp-sourcemaps.

Source Maps

With version 1.1.6 onwards, gulp-javascript-obfuscator can be used in tandem with gulp-sourcemaps in order to generate source maps for your javascript files.

You will need to initialize gulp-sourcemaps prior to running gulp-javascript-obfuscator and write the source maps after, as such:

const sourcemaps = require('gulp-sourcemaps');

gulp.src('file.js')
    .pipe(sourcemaps.init())
    .pipe(javascriptObfuscator({
        compact: true
    }))
    .pipe(sourcemaps.write())
    .pipe(gulp.dest('dist'));

This will output a file.js.map file to the dist directory.

You can chain other gulp plugins as well:

const sourcemaps = require('gulp-sourcemaps');

gulp.src('file.js')
    .pipe(sourcemaps.init())
    // use babel to pre-process javascript files
    .pipe(babel({
        presets: ['@babel/preset-env']
    }))
    .pipe(javascriptObfuscator({
        compact: true
    }))
    .pipe(sourcemaps.write())
    .pipe(gulp.dest('dist'));

Alternative source maps method

For backwards compatibility, if gulp-sourcemaps is not used and obfuscator's sourceMap option is set to true, a .map file will be thrown to Gulp stream. (This method is deprecated and not recommended for future use.)
