How to go up using __dirname in the folder hierarchy

My app structure is:

 /app
     /css
     /js
     ..
 /script
    /server.js

I'm trying to use __dirname to point to /app folder when using

app.use(express.static( __dirname + '/app'));

I dont realy know what to search for in the web, please help.

Solution 1:

if you're in server.js then you mean

app.use(express.static( __dirname + '/../app'));

You can use path module for that.

The path module provides utilities for working with file and directory paths.

const path = require('path');

app.use(express.static(path.join(__dirname, '..', 'app')));
