gulp-uglify won't preserve files order

问题:

When I use gulp-uglify to minify the Javascript files the order gets messed up.

Lets say I have this task working as expected:

var gulp = require('gulp'); var rename = require('gulp-rename'); var gp_concat = require('gulp-concat');  gulp.task('js', function() {     gulp.src([             './public/bower_components/jquery/dist/jquery.min.js',             './public/js/functions.js',         ])         .pipe(gp_concat('combined.js'))         .pipe(gulp.dest(path.js + '/dist')) }); 

Adding the uglify line to it changes the order of the jquery and functions files and places functions.js above jquery.

var gulp = require('gulp'); var rename = require('gulp-rename'); var uglify = require('gulp-uglify'); var gp_concat = require('gulp-concat');  gulp.task('js', function() {     gulp.src([             './public/bower_components/jquery/dist/jquery.min.js',             './public/js/functions.js',         ])         .pipe(gp_concat('combined.js'))         .pipe(gulp.dest(path.js + '/dist'))         .pipe(uglify({             preserveComments: 'license'         }))         .pipe(rename({suffix: '.min'}))         .pipe(gulp.dest(path.js + '/dist')) }); 

Any possible solution to it ? Of course, functions.js is just a plane Javascript file with funtions in it and are not wrapped in an IIFE.

回答1:

Karol Klepacki's answer is correct about using hoist_funs, but that's an option for the UglifyJS compressor. As such it needs to be provided within the compress option:

.pipe(uglify({    preserveComments: 'license',    compress: { hoist_funs: false } })) 

回答2:

Please try disabling functions hoisting:

var gulp = require('gulp'); var rename = require('gulp-rename'); var uglify = require('gulp-uglify'); var gp_concat = require('gulp-concat');  gulp.task('js', function() {     gulp.src([             './public/bower_components/jquery/dist/jquery.min.js',             './public/js/functions.js',         ])         .pipe(gp_concat('combined.js'))         .pipe(gulp.dest(path.js + '/dist'))         .pipe(uglify({             preserveComments: 'license',             hoist_funs: false         }))         .pipe(rename({suffix: '.min'}))         .pipe(gulp.dest(path.js + '/dist')) });
