js minify plugin for gulp
npm install gulp-minify-fork> Minify JavaScript with uglify-es.
gulp-minify is using uglify-es to minify files, this may cause some incompatible issues with earlier language versions for now, see https://github.com/hustxiaoc/gulp-minify/issues/27.So gulp-minify@es5 is for the earlier language versions if your project is not ready for the ECMAScript 6 yet.
Install package with NPM and add it to your development dependencies:
npm install --save-dev gulp-minify
``javascript
var minify = require('gulp-minify');
gulp.task('compress', function() {
gulp.src('lib/*.js')
.pipe(minify({
ext:{
src:'-debug.js',
min:'.js'
},
exclude: ['tasks'],
ignoreFiles: ['.combo.js', '-min.js']
}))
.pipe(gulp.dest('dist'))
});
