How to match flexible url using koa-router in Node.js?

Question

For example,

router.get('/files/...', ->) I want to match /files/a , /files/a/b , /files/a/b/c and so on.

Then, a , a/b , a/b/c will be my handle file path.

Answer 1

This should work for the path, using a regex instead of a string: /\\/files\\/(.*)/ -- then the path info should be in this.params[0] .

Side note -- if you're using this to serve files directly from the server, make sure to check for a directory traversal attack (often looks like using .. in the requested path multiple times) so that you don't inadvertently expose other files on the system.
