Gulp + Browserify任务不起作用（无输出）

Question

I have the following task on my gulpfile.js

gulp.task('default', ['browserify'])
gulp.task('browserify', function () {
  return browserify('./public/js/x.js')
      .bundle()
      .pipe(source('y.js'))
      .pipe(gulp.dest('./public/dist/js'))
})

But after running $ gulp it gives no output. Am I missing something?

Answer 1

I am not sure what your browserify is but I'm gonna assume it's not the deprecated gulp-browserify .

This should work. I tested it:

var gulp = require('gulp');
var browserify = require('browserify');
var source = require('vinyl-source-stream'); // MAKE SURE THIS IS THERE

gulp.task('default', ['browserify'])
gulp.task('browserify', function() {
    return browserify('./public/js/x.js').bundle() // .bundle is a browserify function
    .pipe(source('y.js'))    // Pass to output using vinyl-source-stream
    .pipe(gulp.dest('./public/dist/js'));
});

Since my code looks exactly as yours, can you make sure you have vinyl installed?

npm install --save vinyl-source-stream

and if you haven't already:

npm install --save gulp browserify

npm install -g gulp

I'm now maintaining a repository which collecting all the gulp tasks I use in daily work.

This is the browserify task code

 var gulp = require('gulp') var gulpif = require('gulp-if') var browserify = require('browserify') var gutil = require('gulp-util') var through2 = require('through2') var watchify = require('watchify') var assign = require('object-assign') var babelify = require('babelify') var config = require('config').gulp module.exports = function (is_dev) { var options = { paths: [config.src.js] } if (is_dev) { options = assign({}, options, { debug: true, cache: {}, packageCache: {} }) } var bundler = function () { return through2.obj(function (file, enc, next) { var b = browserify(file.path, options) .transform(babelify.configure({ presets: ['es2015', 'react'], compact: false })) if (is_dev) { b = watchify(b) b.on('update', bundle) b.pipeline.on('file', function (filename) { gutil.log(gutil.colors.green('Bundled: '), filename) }) } return b.bundle(function (err, res) { if(err) { return next(err) } file.contents = res next(null, file) }) }) } function bundle() { is_dev ? gutil.log(gutil.colors.yellow('Bundling...')) : null return gulp.src([ config.src.js + '/**/*.js', '!' + config.src.js + '/lib/**/*.js' ]) .pipe(bundler()) .on('error', function(e) { gutil.log(gutil.colors.red(e.message)) is_dev ? this.emit('end') : null }) .pipe(gulp.dest(config.dist.js)) } return bundle() }
