Coffeescript + Browserify + Gulp + Uglify

Question

been at this one pretty much all day and I can't figure out how to get this working properly. As the topic suggests, I'm having a hell of a time getting this setup working.

I have a project written in Coffeescript using Browserify. I'm trying to write some Gulp build tasks that will Uglify the output for production....pretty standard.

Here's my current setup for my gulpfile:

gulp = require 'gulp'
browserify = require 'browserify'
source = require 'vinyl-source-stream'
buffer = require 'vinyl-buffer'
uglify = require 'gulp-uglify'

# Bundle task
gulp.task('bundle', ->

  browserify(
    entries: ['./client/start.coffee']
    extensions: ['.coffee']
  )

  # Apply transforms and bundle
  .transform('coffeeify')
  .bundle()
  .pipe(source('bundle.js'))
  .pipe(buffer())
  .pipe(uglify())
  .pipe(gulp.dest('./build'))
)

# Run the tasks
gulp.task('default', ['bundle'])

Now this code here works fine for the most part. Running the task properly bundles everything, and then it runs Uglify, resulting in a minified bundle.js file. The problem is when I run my sample HTML page with the JS linked in....I see this error in the console:

When I remove the uglify() step, it works fine...everything is just regular Javascript and the page renders....any ideas? Thanks in advance for the help.

Answer 1

As stated in your comments, the answer is setting the ascii_only property on uglifyJS. Somewhere in your source code you're using non ascii characters that the compressor is trying to process, and that ends up causing the aforementioned error. Setting this flag converts those characters into the \uxxxxx pattern.
