JSON Web Token (JWT) is used to generate access token and refresh token.
For first time login, these tokens are returned to the client.
Access token is a short live token which will be expired in 30 minutes.
Meanwhile, the refresh token has expiry of 24 hours.
The duration can be set to shorter during development or longer period depending on developer's consideration such as for mobile app use.

When the access token has expired, the client need to request for a new access token.
This is done by a JavaScript function by sending the refresh token kept inside the browser cookie.
To make it more secure, the cookie is httponly and only writable from the backend.

Each API or Route can be protected using a server filter (JWTAuthFilter).
When an API path is added into this filter, an access token is required to send in the Authentication header as Bearer.

The refresh token id is stored in the database and can be revoked by Administrator.
The mascot is a sloth (I wish I can draw better), represents a relax and slow life...
It is showing a smiling facial expression similar to the Chinese word less.
Life is short, don't write so long and let people take so much time to read.
Life is sweet, a little emoji can brightens up one's day.
Life is simple, don't complicate an app (social blogging platform) with advanced features.
Life is stupid, it is funny when we recall the past.
Life is selfish, don't care so much what others say about you or not respond to you.
Life is a story, it begins and ends then a new one will start.
Life is having a secret, sometimes you just want to keep it only with some of your mates.

This project is experimental.
However it is a good project to study how I implemented Json Web Token, file uploads, velocity template and there is also a bonus library.
I believe there are much to learn.

I am considering to sell this project as it-is.
Take note that I don't promise I will update this project much in the future.

I remember someone asked before. Is anyone interested?
Will announce the price later when I confirmed.
