NodeJS-相对文件路径

Question

Say have a filepath var dir = "my/file/directory" and I supply a relative file path var rel = "../../other/directory/myFile.js" , how does one compute the real directory:

var dir = "my/file/directory"
var rel = "../../other/directory/myFile.js"
var nDir = func(dir,rel) // returns "my/other/directory/myFile.js"

So far I have found path = require('path') and have been messing around with functions in REPL. However I cannot see where the relative() function, is useful in determining the final path...?

As far as I can see:

var p1 = "root"
var p2 = "my/dir/file.js"
var O  = path.relative(p1,p2) //returns "../my/dir/file.js"

it is returning the relative path... where as, to me, this should return "root/my/dir/file.js" ?

Answer 1

You can take a look at Node Docs on path.resolve , which returns an absolute path. path.relative will return a relative path.
