Replace all URL occurrences of string by another in Node js

Question

I am trying to replace all occurrences of http://xyz.yzx.com/abc/def/ by /qwe/ in String in Node js. I am very new to Node js. So, I think I am doing some mistake in syntax. Following is the code with which I am trying.

var newString = originalString.replace("http:\/\/xyz\.yzx\.com\/abc\/def\//g", "/qwe/");

But this is not doing any replace. Can someone suggest what I am doing wrong? I have tried lot of tweaks but somehow I am not able to achieve the replace all occurrences.

Any suggestions you can give would be really appreciated.

Actually I tried using the same way but somehow I am doing some mistake which I am not able to found out. If you can help me found the mistake in my code, that would be great. — hatellla, Oct 09 '17 at 17:45
If you wanna use regex (`//g`) you dont need the string literal `""` ... — Jonas Wilms, Oct 09 '17 at 17:58
Hmmm, I did not test the code in Node, but a tool tells me, your regex is good enough: https://regex101.com/r/we8LHA/1 Could you provide a repro case? (A string on which the replacement fails) — Igor Soloydenko, Oct 09 '17 at 17:58
@Jonasw If I don't use the "", then it is showing compile time error at :(colon) part. — hatellla, Oct 09 '17 at 18:02

If a string is passed as replaces first argument it will only replace the first occurence ( which is badly implemented in my opinion). So we either use a small workaround:

var newString = originalString
   .split("http:\/\/xyz\.yzx\.com\/abc\/def")
   .join("/qwe/");

Or we need to remove the string literal and escape every / with a \/ ... :/

Now, I see. The regex _literal_ was not used. – Igor Soloydenko Oct 09 '17 at 18:09

This works fine, have a look:

originalString.replace(/\http:\/\/xyz\.yzx\.com\/abc\/def\//g, '/qwe/')
