AURORA is a chatbot that understands and answers questions (in Spanish) about the COVID-19: symptoms, prevention, regulation, the situation in Spain. Don't hesitate to chat with AURORA!

In March 2020, a virus appeared to seriously threaten our health. These were days of widespread confusion, uncertainty, and doubt. The infoxication or generation of many answers to these doubts by the media and social networks (many of which turned out to be false) caused even more unrest in the Spaniards.

At that precise moment, the idea of developing this chatbot was born to generate certainties and a sense of control in the citizens based on truthful information from the Ministry of Health.

With AURORA, a virtual assistant that solves doubts about the COVID-19, it is intended that citizens exercise control over what is in their hands to protect themselves and their loved ones.

The frontend of the chatbot was developed using:

• Angular

• Amazon CloudFront

• Amazon S3

This project was generated with Angular CLI version 8.1.2.

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.

To get more help on the Angular CLI use ng help or go check out the Angular CLI README.
