A regex to remove JS comment on PHP but ignore text inside String

Question

We've tried many solutions about how to remove JS comment by regular expression, but there's one case which always breaks my JS:

const a = "/*";
const b = "*/";

We commonly use Accept: "application/json, text/plain, */*" on our script so it always break our JS.

I'm looking for a regex that can ignore the searching within

"", '', ``

string in JS or any other solution.

Thanks.

FOr what it is worth: In my experience: using regex for these kind of things always bites you in your ass, sooner or later. — Erwin Moller, Sep 30 '19 at 14:46
This is something that would be better solved by using something like `uglify` on the JavaScript at application build time. — Pointy, Sep 30 '19 at 14:47
@anubhava currently I'm using '|\/\*.*\*\/|sU' to search multi line comment. — Stanley Cheung, Sep 30 '19 at 14:50

You can use a negative lookahead after your final / to make sure it's not followed by a * like so:

\/\*.*\/(?!\*)
