Compiling CoffeeScript files

To compile my files from app/ to a single file in _public/ folder: npm install --save gulp-coffee gulp-concat gulp-util

coffee  = require 'gulp-coffee'
concat  = require 'gulp-concat'
gutil   = require 'gulp-util'

gulp.task 'coffee', ->
  gulp.src parameters.app_path+'/**/*.coffee'
  .pipe coffee bare: true
  .pipe concat parameters.app_main_file
  .pipe gulp.dest parameters.web_path+'/js'
  .on 'error', gutil.log
