Decide the upload folder location of Multer middleware

All:

I am new to Express.js, when I deal with file uploading with Multer (https://github.com/expressjs/multer), I specify a multer middleware object:

var upload = multer({dest: 'uploads/'});

But one thing confuse me so much is: No matter where I put this line code( either in sub router file, or app.js), it always creates "uploads" folder under project root( same folder with app.js, views, routes, public... located), even I change it to "./uploads/", it still creates uploads folder under project root.

This confuses me so much, cos when I compare this with require() function, it seems require() uses relative path based on where it is get called while multer is not? I wonder if my understand is correct? And how to change it to relative if mine is correct?

Thanks

It seems to be based on the value of path.resolve(). Where path is defined as var path = require('path').

You can always specify an absolute path (that is relative to the current module) to remove any doubt:

var upload = multer({dest: __dirname + '/uploads/'});
