Summary
After changing my folder structure to keep development and production separate I get a Uncaught SyntaxError: Unexpected token < error.
Note
When I upload my production folder contents via FTP, the site works fine. Only when local do I get the above stated error. Before changing the folder structure, my local server (gulp-connect) worked just fine.
Issue
I an encountering the following errors:
Uncaught SyntaxError: Unexpected token <
My application was working great and ready to launch. I had been working locally with a gulp-connect server. I wanted to create a gulp task that would minify code, copy/paste dependencies, compress image. My end goal would be to have a folder that contained only production ready files.
To do this I created the following folder structure:
The first and biggest change was to copy/paste (using gulp) the node modules dependencies into appropriate folders. As these changed I updated my index.html to reflect to new locations of the scripts from the node_modules folder to /js.

I use compass to compile my SASS so I then updated this accordingly:
require 'compass/import-once/activate'
require 'breakpoint'
# Require any additional compass plugins here.
# Set this to the root of your project when deployed:
http_path = "/builds/development"
css_dir = 'stylesheets'
sass_dir = 'sass'
images_dir = 'images'
javascripts_dir = 'javascripts'
sass_options = false
#tsconfig.json#
My TSConfig file had no changes
