vinyl-buffer 

Convert streaming vinyl files to use
buffers.
An alternative to gulp-streamify
that you can pipe to, instead of being required to wrap your streams.
var browserify = require('browserify')
var source = require('vinyl-source-stream')
var buffer = require('vinyl-buffer')
var uglify = require('gulp-uglify')
var size = require('gulp-size')
var gulp = require('gulp')
gulp.task('build', function() {
var bundler = browserify('./index.js')
return bundler.bundle()
.pipe(source('index.js'))
.pipe(buffer())
.pipe(uglify())
.pipe(size())
.pipe(gulp.dest('dist/'))
})
Usage

vinylBuffer()
Creates a transform stream that takes vinyl files as input, and outputs
modified vinyl files as output. If file.isStream()
, file.contents
will
be converted to a Buffer
before being emitted again – otherwise, the file
will be emitted immediately.
