Compiled with Syntax error - Invalid regular expression

[MatusSkerlik]

When i run project in "developing" mode everything works as it should.
npm run dev
But when i bundle code into Electron and run application, i am getting error in /app/dist/bundle.js
npm run package

Syntax error: Invalid regular expression: missing /

Hey @MatusSkerlik! We really appreciate you taking the time to report an issue. The collaborators

I think you'll need to narrow this down a bit, there isn't nearly enough information to go on. What code is failing? Do you have a sense for what the error is? What makes you say this is a Babel issue?

The link to your repo also doesn't work.

[MatusSkerlik]

Sorry for that link, it works now.
Like i said everything works until i run bundled application.
I think it is problem with babel or my babel configuration because code is converted from es6 to es5 and that is babel functionality. I really dont know where is the problem, but when i use syntax validator to test file /app/dist/bundle.js (generated by babel-pollyfill) there is a syntax error.

[loganfsmyth]

I'm happy to help if this is a Babel issue, but it would be great if you could narrow it down. That file is 2MB. What regex is broken? What does it look like in the original source? What change happened to make it break, at least from what you can tell?

[MatusSkerlik]

it is on 12 line, it is loadash.js 1.8.3 section of code i think, please go to http://esprima.org/demo/validate.html and copy contents of bundle.js in it so you can see. When i fix this line another syntax error will show up on line 37, modernizr.js section, and it continues for ever. And only regex i use is in /app/components/ReserveGrid.js, but i tried to comment it, but with same results after compilation. Im sure that error is not in my code, but probably in configuration of webpack or babel ? I don't know really.

[loganfsmyth]

Line 12 is 90000 characters long. Please include the working vs failing regexes here so we can compare.

[MatusSkerlik]

This lines don't work.
generated code -> line 12 var W=//g;,
generated code -> line 36 Fe=//g, He=//g and so on.
I think that first slash is representing something like new line because everything is form end of line.
It is helpful in some way ?

[loganfsmyth]

If you remove the BabiliPlugin from your Webpack config, does it work? It's possible that's causing some issue.

[MatusSkerlik]

Yes, it works now. Thank you so much, you have saved my ass 👍

[loganfsmyth]

Babili is still beta-level, so it's certainly possible there is some bug you are hitting here.

[MatusSkerlik]

Thank you again, i would not use it if i knew it. It took my so much time.

[boopathi]

@MatusSkerlik looks like some bug with Babili in regexp. Might be the same as babel/minify#440. Can you try with Babili Option - regexpConstructors set to false

new BabiliPlugin({
  regexpConstructors: false
})

in your webpack config.

[Nantris]

For me, the package Chrono-Node 1.3.1 and 1.2.5 both cause this error. Adding regexpConstructors: false makes no difference unfortunately.

[merges]

Ditto; this is an issue that chrono-node 1.3.1 raises for me with Babili.
