Relative path for static files in Expressjs or Koajs

Question

I have a Structure for my application similar to below :

• ApplicationA
  • a.js
• ApplicationB
  • b.js
• ApplicationC
  • c.js
• public

i have some static file in public directory . how can application a.js that located in ApplicationA directory access to public directory.

Answer 1

var path = require("path")

var target = "../public/"

var resolved = path.relative(__dirname, target)

Answer 2

Do you mean you want to go up a directory? If so use ../ to go up a directory from where you are so for instance if ApplicationA and public are in the same directory you could use:

../public/filename.file
