I have a string

var str = "C:\Program Files\nodejs\node_modules"

I want to replace the "C:\Program Files\" part with a hyperlink part "https://" so that the final outcome is

"https://nodejs/node_modules"

The first step to replace the slases with regex I already did it with

replace(/\\\\/gi,"/")

hence it became

"C:/Program Files/nodejs/node_modules"

So, the regex for the final outcome ,am facing difficulties.

You might use 2 capture groups:

^[A-Z] :\\(?:[^\\\n]*\\)*([^\\\n] )\\([^\\\n] )$

• ^ Start of string
• [A-Z] :\\ Match 1 chars A-Z : and \
• (?:[^\\\n]*\\)* Optional repetitions of any char except \ ad then match \
• ([^\\\n] ) Capture group 1 Match optional chars other than \
• \\ Match \
• ([^\\\n] ) Capture group 2 the same as for capture group 1
• $ End of string

And replace with

https://$1/$2

See a regex demo.

const regex = /^[A-Z]:\\(?:[^\\\n]*\\)*([^\\\n] )\\([^\\\n] )$/gm;
const str = `C:\\Program Files\\nodejs\\node_modules`;
const result = str.replace(regex, `https://$1/$2`);
console.log(result);
