如何在 Gulp 中使用 Browserify 丑化输出？

我尝试在 Gulp 中丑化 Browserify 的输出，但它不起作用。

gulpfile.js

var browserify = require('browserify');
var gulp = require('gulp');
var uglify = require('gulp-uglify');
var source = require('vinyl-source-stream');

gulp.task('browserify', function() {
    return browserify('./source/scripts/app.js')
        .bundle()
        .pipe(source('bundle.js'))
        .pipe(uglify()) // ???
        .pipe(gulp.dest('./build/scripts'));
});

据我了解，我无法按照以下步骤进行操作。我需要在一根管道中制作以保留顺序吗？

gulp.task('browserify', function() {
    return browserify('./source/scripts/app.js')
        .bundle()
        .pipe(source('bundle.js'))
        .pipe(uglify()) // ???
        .pipe(gulp.dest('./source/scripts'));
});

gulp.task('scripts', function() {
    return grunt.src('./source/scripts/budle.js')
        .pipe(uglify())
        .pipe(gulp.dest('./build/scripts'));
});

gulp.task('default', function(){
    gulp.start('browserify', 'scripts');
});

你实际上已经非常接近了，除了一件事：

• 你需要转换流媒体乙烯基文件对象由以下给出source() with vinyl-buffer因为gulp-uglify（和大多数 gulp 插件）适用于buffered乙烯基文件对象

所以你可以用这个代替

var browserify = require('browserify');
var gulp = require('gulp');
var uglify = require('gulp-uglify');
var source = require('vinyl-source-stream');
var buffer = require('vinyl-buffer');

gulp.task('browserify', function() {
  return browserify('./source/scripts/app.js')
    .bundle()
    .pipe(source('bundle.js')) // gives streaming vinyl file object
    .pipe(buffer()) // <----- convert from streaming to buffered vinyl file object
    .pipe(uglify()) // now gulp-uglify works 
    .pipe(gulp.dest('./build/scripts'));
});

或者，您可以选择使用vinyl-transform相反，它同时照顾两者流媒体 and buffered为您提供乙烯基文件对象，就像这样

var gulp = require('gulp');
var browserify = require('browserify');
var transform = require('vinyl-transform');
var uglify = require('gulp-uglify');


gulp.task('build', function () {

  // use `vinyl-transform` to wrap the regular ReadableStream returned by `b.bundle();` with vinyl file object
  // so that we can use it down a vinyl pipeline
  // while taking care of both streaming and buffered vinyl file objects
  var browserified = transform(function(filename) {
    // filename = './source/scripts/app.js' in this case
    return browserify(filename)
      .bundle();
  });

  return gulp.src(['./source/scripts/app.js']) // you can also use glob patterns here to browserify->uglify multiple files
    .pipe(browserified)
    .pipe(uglify())
    .pipe(gulp.dest('./build/scripts'));
});

上述两种方法都会达到同样的效果。

它只是关于你想要如何管理你的管道（在常规 NodeJS Streams 和流式乙烯基文件对象和缓冲乙烯基文件对象之间转换）
