This project was generated with Angular CLI version 7.2.3.

Deployed on Heroku: https://cs5610-final.herokuapp.com This web application is designed for designing housing trading platform. Traditional house tradings are time consuming and hard to efficiently connect buyers and sellers and update the information in real time. Our website procides the platform for both sides which could realize the functions of posting houses information and fulfilling trades in a convenient way.

We built the website using MEAN stack. The frontend part was designed and implemented in MVC model. Routering module was used to switch pages in frontend. By displaying the front end information, we used the Bootstrap library, the Font-awesome library. Landing homepage used flash to show animation and will redirect to login page. Grid system used to display houses. External public webservice Google Map APIs are used for getting Geolocation and displaying maps in house detail page. For backend development, we used express framework and injected passport to help realize the authentication. Provided local strategy and facebook strategy for the authentication. AuthGuard was used to protect the profile page and user could only see this page after they logged in. We implemented the RESTful APIs to achieve the CRUD operations. The data is stored in MLab added on Heroku.

The web application mainly contains User, House, Comment domain objects. The definiation of each object is in the model part. User contains login, profile, register components. House contains list, edit, new, detail, order components. House-detail contains comment and map component. Comment contains list, edit, new components. Every user could have access to user objects and comment objects. User service provides endpoints for user related APIs. House service provides endpoints for house related APIs. Comment service provides endpoints for comment related APIs. Public service provides endpoints for external APIs.

There are three roles: Admin, Seller, Buyer.

• CRUD their own comments

• Update profile

Run ng test to execute the unit tests via Karma. Admin: admin/admin Seller: alice/alice Buyer: bob/bob
