JSON API URL : https://jsonmock.hackerrank.com/api/weather?name=<name>

• Angular CLI Version: 10.0.9
• Angular Core Version: 10.0.9
• Node Version: 12.18.3
• Default Port: 8000

The component must have the following functionalities:

• The input should initially be empty. The user can type a city name into this input box to search for weather details for this city.

• Clicking on the Search button should make an API GET call to the URL https://jsonmock.hackerrank.com/api/weather?name=<name> using the Angular HttpClient module. Here, <name> is the city name entered into the text box. For example, for the value Dallas, the API hit has to be https://jsonmock.hackerrank.com/api/weather?name=Dallas. You will always get data for cities Dallas and Oakland.

• The response contains a data field, where data is an array of objects, and each object is a weather record. We only need to use the first record from the array for rendering in this challenge. The sample format of the data field is given below:

  "data": [
    {
      "name": "Dallas",
      "weather": "12 degree", // Format is always "<value> degree"
      "status": [
        "Wind: 2Kmph", // String
        "Humidity: 5%" // String
      ]
    }
  ]

• The weather details should be rendered inside <div data-test-id="weather-details"></div>. This div should not be rendered initially since no API has been hit yet.

• Each weather record contains a weather field. Retrieve the value and display in the following element - <span data-test-id="result-temperature"></span>.

• If value in weather field is less than 20, render cold weather icon by rendering <i data-test-id="icon-cold"></i>. If the value is greater than or equal to 20, render sunny weather icon by rendering <i data-test-id="icon-sunny"></i>.

• Each weather record contains a status field which is an array of strings.

• The first string denotes the wind value and the second string denotes the humidity value.

  1. Render wind value in
  2. Render humidity value in

• If no records are returned for any city by the API, you must render <div data-test-id="no-result">No Results Found</div> instead, and this element must be visible only when the data field is an empty array. This div should not be rendered initially since no API has been hit yet.

• Please note that the input field accepts only text. Test cases take care of calling the API with valid input, so writing input validation is not required.

• For testing purposes, please use the following cities and their corresponding weather conditions:

  Dallas - Cold
  Oakland - Sunny

• The input should have the data-test-id attribute app-input.
• The Search button should have the data-test-id attribute submit-button.
• The weather details should have the data-test-id attribute weather-details.
• The sunny icon should have the data-test-id attribute icon-sunny.
• The cold icon should have the data-test-id attribute icon-cold.
• The span showing temperature should have the data-test-id attribute result-temperature.
• The div showing wind information should have the data-test-id attribute result-wind.
• The div showing wind information should have the data-test-id attribute result-humidity.
• The No Results Found div should have the data-test-id attribute no-result.
