5 | ## Introduction
6 | This is a code repository for the corresponding video tutorial.

/routes/users.js:

 1 | import express from 'express';

 7 | router.get('/', getUsers);
 8 | 
 9 | router.post('/', createUser);
10 | 
11 | router.get('/:id', getUser);
12 | 
13 | router.delete('/:id', deleteUser);
14 | 
15 | router.patch('/:id', updateUser);
16 | 
17 | export default router;
