This project was generated with Angular CLI.

This is a simple login page made with MEAN stack (MongoDB, ExpressJS, Angular 6, NodeJS).

• User registration.
• User login.
• User Authorization.

1. When user enters email and password and when both of them are correct we return an access token (generated with jwt)
2. This access token is stored in localstorage of the browser.
3. Now if user leaves the page and opens the same site again we check to see if there is any access token present in user's localstorage.
4. if access token is present - > we verify that access token and redirect user to the profile page.
5. if access token is not present - > we keep user on the same page.

• NodeJS and ExpressJS is inside restApi/
• MongoDB database is in user_db/
• Angular Components are in src/app

• MEAN stack (Angular 2+)
• ES6 Javascript (specially promises)
• JWT: Json Web Token it is a libray to generate random token it has 2 function jwt.sign() to create token and jwt.verify() to verify
• bcrypt - Library to hash passwords, I've used two functions in this project bcrypt.hash() to hash password and bcrypt.compare to compare string with hashed password.

1. Install npm and Angular Client npm install @angular/cli (ignore if already installed)
2. In command prompt type npm install to download starter packages.
3. cd restApi and type npm install bcrypt,jsonwebtoken,mongoose,express
4. Install MongoDB
5. Go to bin folder in your mongodb directory, Mine is in c:/program files/mongodb/server/3.6/bin and type mongostore <path of user_db folder>

1. Change directory to your project and ng serve to start angular server
2. Change directory to bin folder of your mongodb installation folder, Mine is c:/program files/mongodb/server/3.6/bin and type mongod then open new command prompt and type mongo
3. Change directory to restApi/ and type node index.js to start Node Server

Run ng serve for a dev server. Navigate to http://localhost:4200/. The app will automatically reload if you change any of the source files.

Run ng generate component component-name to generate a new component. You can also use ng generate directive|pipe|service|class|guard|interface|enum|module.

Run ng build to build the project. The build artifacts will be stored in the dist/ directory. Use the -prod flag for a production build.

Run ng test to execute the unit tests via Karma.

Run ng e2e to execute the end-to-end tests via Protractor.
