javascript - NodeJS - convert relative path to absolute

Question

In my File-system my working directory is here:

C:empacd

and under bb there's file: tmp.txt

C:empabmp.txt

If I want to go to this file from my working directory, I'll use this path:

"../../bb/tmp.txt"

In case the file is not exist I want to log the full path and tell the user:
"The file C:empabmp.txt is not exist".

My question:

I need some function that convert the relative path: "../../bb/tmp.txt" to absolute: "C:empabmp.txt"

In my code it should be like this:

console.log("The file" + convertToAbs("../../bb/tmp.txt") + " is not exist")

Answer 1

Use path.resolve

try:

resolve = require('path').resolve
resolve('../../bb/tmp.txt')
