如何在 Gulp 中使用 Browserify 丑化输出?

2022-01-12 00:00:00 node.js javascript gulp browserify uglifyjs

我试图在 Gulp 中对 Browserify 的输出进行 uglify，但它不起作用.

I tried to uglify output of Browserify in Gulp, but it doesn't work.

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.我需要在一个管道中制作以保留序列吗?

As I understand I cannot make it in steps as below. Do I need to make in one pipe to preserve the sequence?

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');
});

推荐答案

其实你们已经很接近了，除了一件事:

You actually got pretty close, except for one thing:

  • 您需要将 source() 给出的 streaming 乙烯基文件对象转换为 vinyl-buffer 因为 gulp-uglify(和大多数 gulp 插件)适用于缓冲乙烯基文件对象
  • you need to convert the streaming vinyl file object given by source() with vinyl-buffer because gulp-uglify (and most gulp plugins) works on buffered vinyl file objects

所以你会用这个来代替

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 代替它为您处理 streaming 和 buffered 乙烯基文件对象，例如所以

Or, you can choose to use vinyl-transform instead which takes care of both streaming and buffered vinyl file objects for you, like so

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'));
});

以上两种方法都可以达到相同的效果.

Both of the above recipes will achieve the same thing.

这只是关于您希望如何管理管道(在常规 NodeJS 流和流式乙烯基文件对象和缓冲乙烯基文件对象之间进行转换)

Its just about how you want to manage your pipes (converting between regular NodeJS Streams and streaming vinyl file objects and buffered vinyl file objects)
