SQL Queries

First of all, you need to create the tables in your PostgreSQL database

CREATE TABLE users
(id_user serial NOT NULL PRIMARY KEY,
 username VARCHAR(50) NOT NULL,
 email VARCHAR(255) UNIQUE NOT NULL,
 password VARCHAR(200) NOT NULL,
 logged BOOLEAN NOT NULL
);

CREATE TABLE posts
(
id_post serial NOT NULL PRIMARY KEY,
title VARCHAR(50) NOT NULL,
content VARCHAR(140) NOT NULL,
date DATE default current_date,
id_user INT NOT NULL,
FOREIGN KEY (id_user) REFERENCES users (id_user)
)

Dotenv variables

DB_USER
DB_PASSWORD
DB_HOST
DB_PORT
DB_DATABASE
ULTRA_SECRET_KEY

How to use it

Go to your Rest Client (I use Advanced Rest Client) to make your requests.

First of all we will get the posts that we have in our database

Then, if we add an email in the URL, we can select posts by authors

Now, we are going to create a user profile to upload posts.

As you can see in your database, the create profile has a column called logged with the false value by default.

Now, make a post request to log in with the new account

The logged value will change in your database

Paste your token in the "access_token" header, we need the logged value true and our token to send posts

Then wi will make a GET request to logout our user, this only will change the logged value to false, so our token isn't value anymore and the API REST will send us the message:

{ msg: 'Token deleted' }

If we try to send a new post, the API REST will send the message:

{ msg: 'Invalid token' }

http requests are available to import to postman in utils folder (API_rest_sql_postman_requests.json)
