NodeJS - convert relative path to absolute

Question

In my File-system my working directory is here:

C:\temp\a\b\c\d

and under b\bb there's file: tmp.txt

C:\temp\a\b\bb\tmp.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:\temp\a\b\bb\tmp.txt is not exist".

My question:

I need some function that convert the relative path: "../../bb/tmp.txt" to absolute: "C:\temp\a\b\bb\tmp.txt"

In my code it should be like this:

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

Solution 1

Use path.resolve

try:

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

Solution 2

You could also use __dirname and __filename for absolute path.

Use this only to know the absolute path of the current directory in which the file resides and the current file respectively.

[harveyhans]

you can also use const {resolve} = require("path");

@DarkKnight, Is there any way to avoid ../../../etc?

[DarkKnight]

@Code_Crash you can use a variable or change working directory like this: stackoverflow.com/q/19803748/4578017 A variable is preferred since changing working directory might cause unwanted side effects
