Can I use require(“path”).join to safely concatenate urls?

Question

Is this safe to use require(\"path\").join to concatenate URLs, for example:

require(\"path\").join(\"http://example.com\", \"ok\"); 
//returns          


        

Answer 1

No! On Windows path.join will join with backslashes. HTTP urls are always forward slashes.

How about

> ["posts", "2013"].join("/")
'posts/2013'
