将 stream-combiner2 与 Gulp 4 一起使用

Question

我正在尝试将 stream-combiner2 与我的 Gulp 4 任务一起使用，正如 the current version of this recipe 中所建议的那样。但是，我总是收到：

The following tasks did not complete: build:js
Did you forget to signal async completion?

我已经阅读了很好的信息 in this answer about Gulp 4 async completion，但我在将其应用到我的任务中时遇到了问题。这是我拥有的：

const browserify = require('browserify')
const buffer = require('vinyl-buffer')
const combiner = require('stream-combiner2')
const gulp = require('gulp')
const jsDest = 'static/js'
const jsPath = 'build/js'
const jsSrc = `${jsPath}/**/*.js`
const source = require('vinyl-source-stream')
const sourcemaps = require('gulp-sourcemaps')
const uglify = require('gulp-uglify')

gulp.task('build:js', function () {
    const combined = combiner.obj([
        browserify({
        entries: `${jsPath}/main.js`,
        debug: true
        }),
        source(`${jsPath}/main.js`),
        buffer(),
        sourcemaps.init({ loadMaps: true }),
        uglify(),
        sourcemaps.write('./'),
        gulp.dest(jsDest)
    ])

    combined.on('error', console.error.bind(console))

    return combined
})

Answer 1

经过几个小时的修改后，我受够了这个任务根本没有做我想做的事情（参见 post 的评论）并求助于已弃用的 gulp-browserify .这是该插件的解决方案，但我完全愿意接受可以将 stream-combiner2 与 browserify 本身正确结合的答案，因为那样会好得多。

const combiner = require('stream-combiner2')
const gulp = require('gulp')
const jsDest = 'static/js'
const jsSrc = 'build/js/*.js'
const sourcemaps = require('gulp-sourcemaps')
const uglify = require('gulp-uglify')

gulp.task('build:js', function () {
const combined = combiner.obj([
    gulp.src(jsSrc),
    sourcemaps.init(),
    browserify(),
    uglify(),
    sourcemaps.write('.'),
    gulp.dest(jsDest)
])

combined.on('error', console.error.bind(console))

return combined
})

Answer 2

不知何故我错过了这个fantastic recipe for browserify with multiple sources and destinations。它让我终于得到了我想要的东西，包括格式正确的错误处理：

const browserify = require('browserify')
const buffer = require('gulp-buffer')
const combiner = require('stream-combiner2')
const gulp = require('gulp')
const gutil = require('gulp-util')
const jsDest = 'static/js'
const jsSrc = 'build/js/*.js'
const sourcemaps = require('gulp-sourcemaps')
const tap = require('gulp-tap')
const uglify = require('gulp-uglify')

gulp.task('build:js', function () {
    const combined = combiner.obj([
        gulp.src(jsSrc, { read: false }),
        tap(function (file) {
            gutil.log('bundling ' + file.path)
            file.contents = browserify(file.path, { debug: true }).bundle()
        }),
        buffer(),
        sourcemaps.init({ loadMaps: true }),
        uglify(),
        sourcemaps.write('./'),
        gulp.dest(jsDest)
    ])

    combined.on('error', console.error.bind(console))

    return combined
})
