First of all, please note that token expiration and revoking are two different things.

Expiration only happens for web apps, not for native mobile apps, because native apps never expire.
Revoking only happens when (1) uses click the logout button on the website or native Apps;(2) users reset their passwords; (3) users revoke their tokens explicitly in the administration panel.

1. How to hadle JWT expiration

A JWT token that never expires is dangerous if the token is stolen then someone can always access the user's data.

Quoted from JWT RFC:

System Design Cheatsheet

Picking the right architecture = Picking the right battles + Managing trade-offs

Basic Steps

Clarify and agree on the scope of the system

User cases (description of sequences of events that, taken together, lead to a system doing something useful)
- Who is going to use it?
- How are they going to use it?

Attempting mysql -u root fails with Access denied for user 'root'@'localhost immediately after doing brew install mariadb and starting mariadb with brew services start mariadb.

To fix it (with MariaDB still running):

sudo mysql then enter your Mac user password
ALTER USER 'root'@'localhost' IDENTIFIED BY 'newrootpassword'; replacing newrootpassword with the password you wish to use for the MariaDB root user.
Ctrl-C to exit mysql.

You should then be able to connect to MariaDB with mysql -u root -p, then entering the root password when prompted.

Transparent Restaurant Backend

In this task, you're going to implement a REST API for a interacting with a menu of a restaurant. The menu is given to you as a JSON file which you will parse and perform operations on. The required features will be listed below.

Description

In this restaurant, honesty is extremely promoted. So extreme, that the restaurant declares that differing quality of ingredients are used in their meals. Like that's not enough, it also allows the customers to choose the ingredients of each meal in different qualities. Each ingredient has the following quality levels:

low: the cheapest
medium: moderate

	# This is an adaptation of code I wrote to download a private binary from GitHub. Such...pain.
	# Why can't GitHub just offer a standardized URL you can download a release binary from and attach
	# your Github Personal Access Token as a header?
	#
	# Since this code is an adaptation it hasn't been directly tested, but the code it was adapted from works
	# and hopefully you can get the missing piece you're after by looking here.
