This is a basic MEAN stack (MongoDB, Express.js, Angular, Node.js) single-page web application project written in TypeScript. It is a simple user login/account management app with JWT authentication. You can register a new user account with your email address, name and password. After successful registration, you can log in and view your user data. This app was created for learning purpose, but is might be useful as a starting-point for other projects. The API uses:

• MongoDB (Mongoose) noSQL database
• node.js (Express) RESTful API
• Angular 9 (Typescript) SPA
• Bootstrap 4 style
• JWT for authentication

If any question, please do not hesitate to contact me.

• download and install Docker and Docker-Compose
• clone or download the content of the repository
• open a terminal and navigate to the containing folder
• write "docker-compose up --build" and press Enter

• download and install node.js, MongoDB
• clone or download the content of the repository

MongoDB

• check if MongoDB server is running as a service

Backend

• open a terminal and navigate to the folder "express-server"
• write "npm install" and press Enter
• after package installation is finished, write "npm start" in the terminal and press Enter

Frontend

• open another terminal and navigate to the folder "angular-client"
• write "npm install" and press Enter
• after package installation is finished, write "npm start" in the terminal and press Enter

• if no error message in the terminal, open your browser (recommended: latest Chrome, Firefox, Safari, Edge Chromium or Chromium) and open: http://localhost:4200
• first register a user account, then log in and after that you can diplay your user data and also log out
• after testing go back to the terminals and press "Ctrl+C" to stop the the backend and frontend as well

This application needs to be extended with exception handling. There are some already known issues which may cause error when it is not used correctly. I only tested the app with correct input values.

• add possibility to modify and delete account
• Facebook authentication
• adding roles (admin, user)

There are several online source which I used to create this web app.
