Gulp plugin for javascript-obfuscator
Install the package with npm:
$ npm install --save gulp-javascript-obfuscator
const gulp = require('gulp'); const javascriptObfuscator = require('gulp-javascript-obfuscator'); gulp.src('file.js') .pipe(javascriptObfuscator()) .pipe(gulp.dest('dist'));
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.
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'));
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.)
