WeatherNow was made with Angular 5 using Typescript and was developed based on components, with specific functions, based on the principles Clean Code, SOLID and DRY. Component style was created from CSS3 with SCSS.

• Components:

AppComponent - Responsible for creating the application and displaying the main page - single route created.

TopBar - Component responsible for creating the application header.

CardWeather - Receives as parameter some properties like the name of the city and country and is responsible for the construction and maintenance of the cards displayed on screen.

Checks if the application has cached data, and if it does not, check the service every 10 minutes.

• Services:

WeatherService - Responsible for consulting the OpenWeatherMap API and returning Weather models with their respective city.

CacheService - Data is being cached in LocalStorage for 10 minutes, from the service CacheService of the ng2-cache package.

• Models:

City - Class that has the data inherent to City.

Weather - Class that has Weather data.

• Pages:

Home - Application main page that builds the cards from a list of options.

• Prerequisites:

This project have dependencies that require Node 6.9.0 or higher, together with NPM 3 or higher.

Prepare the development enviroment by running:

npm install -g @angular/cli

Install app dependencies by running inside app path:

npm i

Serve app in development mode by running:

ng serve

Then open the address http://localhost:4200/ in the browser. The app will automatically reload if you change any of the source files.

You can run tests by running:

ng test

To execute the unit tests via Karma.

• The following unit tests were implemented:

AppComponent:

should create the app

should have as title 'WeatherNow'

CardWeatherComponent:

should create

should not display error

should display error

should display in blue temperatures equal to or less than 5 degrees

should display in orange temperatures above 6 degrees and equal to or below 25

should display in red temperatures above 26 degrees

TopBarComponent:

should create

should render the logo

HomeComponent:

should create

must have a list with options for the cards

WeatherService:

getWeatherByCityName()

should return an Observable<Weather>

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.

• Improve test coverage
• Implement E2E tests
