Coffeescript + Browserify + Gulp + Uglify

Question

I’ve been in this all day, and I can’t figure out how to do it right. As follows from this topic, I get a hell of a time when this setting works.

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

Here is 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 works fine for the most part. Running the task properly binds everything together and then starts Uglify, resulting in a mini bundle.js file. The problem is when I run my HTML page with a JS connection .... I see this error in the console:

 Uncaught SyntaxError: Invalid regular expression: /[ªµºÀ-ÖØ-öø-ˈ-Ë'Ë -ˤˬˮͰ-ʹͶͷͺ-ͽΆΈ-ΊΌΎ-ΡΣ-ϵϷ-ÒÒŠ-Ô§Ô±-Õ–Õ™Õ¡-Ö‡×-תװ-×²Ø -يٮٯٱ-Û"Û•Û¥Û¦Û®Û¯Ûº-Û¼Û¿ÜÜ'-ܯÝ-ޥޱߊ-ßªß´ßµßºà €-à •à šà ¤à ¨à¡€-ࡘࢠࢢ-ࢬऄ-हऽà¥à¥˜-ॡॱ-ॷॹ-ॿঅ-ঌà¦à¦à¦"-নপ-রলশ-হঽৎড়à§à§Ÿ-ৡৰৱਅ-ਊà¨à¨à¨"-ਨਪ-ਰਲਲ਼ਵਸ਼ਸਹਖ਼-ੜਫ਼ੲ-ੴઅ-àªàª-àª'àª"-નપ-રલળવ-હઽà«à« ૡଅ-ଌà¬à¬à¬"-ନପ-ରଲଳଵ-ହଽàœààŸ-à¡à±à®ƒà®…-ஊஎ-à®à®'-கஙசஜஞடணதந-பம-ஹà¯à°…-ఌఎ-à°à°'-నప-ళవ-హఽౘౙౠౡಅ-ಌಎ-à²à²'-ನಪ-ಳವ-ಹಽೞೠೡೱೲഅ-ഌഎ-à´à´'-ഺഽൎൠൡൺ-ൿඅ-ඖක-නඳ-රලව-à·†à¸-ะาำเ-ๆàºàº‚ຄງຈຊàºàº"-ທນ-ຟມ-ຣລວສຫàº-ະາຳຽເ-ໄໆໜ-ໟༀཀ-ཇཉ-ཬྈ-ྌက-ဪဿá-á•áš-áá¡á¥á¦á®-á°áµ-á‚á‚Žá‚ -ჅჇáƒáƒ-ჺჼ-ቈቊ-á‰á‰-ቖቘቚ-á‰á‰ -ኈኊ-áŠáŠ-ኰኲ-ኵኸ-ኾዀዂ-ዅወ-ዖዘ-áŒáŒ'-ጕጘ-ášáŽ€-áŽáŽ -á´á-ᙬᙯ-ᙿáš-áššáš -ᛪᛮ-ᛰᜀ-ᜌᜎ-áœ'ᜠ-ᜱá€-á'á -á¬á®-á°áž€-áž³áŸ—áŸœá  -ᡷᢀ-ᢨᢪᢰ-ᣵᤀ-ᤜá¥-á¥á¥°-ᥴᦀ-ᦫá§-ᧇᨀ-ᨖᨠ-á©"ᪧᬅ-ᬳá…-á‹á®ƒ-ᮠᮮᮯᮺ-ᯥᰀ-á°£á±-á±á±š-ᱽᳩ-ᳬᳮ-ᳱᳵᳶᴀ-ᶿḀ-ἕἘ-á¼á¼ -ὅὈ-á½á½-ὗὙὛá½á½Ÿ-ώᾀ-ᾴᾶ-ᾼιῂ-ῄῆ-á¿Œá¿-á¿"á¿–-Ίῠ-Ῥῲ-ῴῶ-ῼâ±â¿â‚-ₜℂℇℊ-â„"â„•â„™-â„ℤΩℨK-â„ℯ-ℹℼ-â„¿â……-â…‰â…Žâ… -ↈⰀ-Ⱞⰰ-ⱞⱠ-ⳤⳫ-ⳮⳲⳳⴀ-ⴥⴧâ´â´°-ⵧⵯⶀ-ⶖⶠ-ⶦⶨ-ⶮⶰ-ⶶⶸ-ⶾⷀ-ⷆⷈ-â·Žâ·-â·–â·˜-ⷞⸯ々-〇〡-〩〱-〵〸-〼ã-ã‚–ã‚-ã‚Ÿã‚¡-ヺー-ヿㄅ-ã„ㄱ-ㆎㆠ-ㆺㇰ-ㇿã€-䶵一-鿌ꀀ-ê'Œê"-ê"½ê"€-ꘌê˜-ꘟꘪꘫꙀ-ꙮꙿ-êš—êš -ꛯꜗ-ꜟꜢ-ꞈꞋ-ꞎêž-êž"êž -Ɦꟸ-ê ê ƒ-ê …ê ‡-ê Šê Œ-ê ¢ê¡€-ꡳꢂ-ꢳꣲ-ꣷꣻꤊ-ꤥꤰ-ê¥†ê¥ -ꥼꦄ-ꦲê§ê¨€-ꨨꩀ-ê©‚ê©„-ê©‹ê© -ꩶꩺꪀ-ꪯꪱꪵꪶꪹ-ꪽꫀꫂꫛ-ê«ê« -ꫪꫲ-ê«´ê¬-ꬆꬉ-ꬎê¬'-ê¬–ê¬ -ꬦꬨ-ꬮꯀ-ꯢ가-힣ힰ-ퟆퟋ-ퟻ豈-ï©ï©°-龎ff-stï¬"-ﬗï¬ï¬Ÿ-ﬨשׁ-זּטּ-לּמּï€ïïƒï„ï†-ï®±ï¯"-ï´½ïµ-ï¶ï¶'-ﷇﷰ-ﷻﹰ-ﹴﹶ-ﻼＡ-Ｚï½-ｚｦ-ﾾￂ-ￇￊ-ï¿ï¿'-ï¿—ï¿š-ï¿œ]/: Range out of order in character class 

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

Answer 1

As stated in your comments, the response sets the ascii_only property to uglifyJS. Somewhere in the source code, you are using non-ascii characters that the compressor is trying to process, and this leads to the aforementioned error. Setting this flag converts these characters to the \ uxxxxx pattern.
