JWT User Authentication in Next.js Web Application(implemented with JSON Web Tokens) by using cookies

This is a Next.js project bootstrapped with create-next-app boilerplate startup.

Getting Started

You can run this app in the development server by using next commands:

npm run dev
# or
yarn dev

Before using this app, you must first create database with users:

CREATE DATABASE IF NOT EXISTS Users;

After that, create a table users:

  ...
  CREATE TABLE users (
	id INT AUTO_INCREMENT,
    user_name VARCHAR(20) NOT NULL UNIQ NOT NULL UNIQUE,
    createdAt DATETIME DEFAULT CURRENT_TIMESTAMP,
    password TEXT NOT NULL,
    PRIMARY KEY(id)
  ); 
  ...

Now, insert some data into adatabase:

    INSERT INTO users (user_name, email, password) VALUES ('Daniel', 'daniel@mail.com', your_password);
    ...

Inside your root folder, create environment file (.env.local) with the following content:

MYSQL_HOST=localhost
MYSQL_USER=root
MYSQL_DATABASE=Users
MYSQL_PASSWORD=***

JWT_KEY=26b*****-****-****-****-*****0bed42b

Here, all four MYSQL_ environment variables are intialized according your MySQL RDBMS configuration on your mashine. So, change all these values with corresponding values on your local mashine. JWT_KEY is a just secret key which you can create by your own. You can create one by Online GUID / UUID Generator.

• Open your local server host http://localhost:3000 inside your browser to see the welcome page.

You can start editing the page by modifying pages/index.js. The page auto-updates as you edit the file.

API routes can be accessed on http://localhost:3000/api/hello. This endpoint can be edited in pages/api/hello.js.

The pages/api directory is mapped to /api/*. Files in this directory are treated as API routes instead of React pages.
