Completion Instructions

Functionality to be added

The app must have the following functionalities

• When the page is opened,
  • Make HTTP GET request to the cryptocurrenciesApiUrl
  • loader should be displayed while fetching the data
  • After fetching the data, the updated list of cryptocurrencies should be displayed

API Requests & Responses

cryptocurrenciesApiUrl

API: https://apis.ccbp.in/crypto-currency-converter

Method: GET

Description:

Returns a response containing the list of cryptocurrencies

Response

[
  {
    "currency_name": "Bitcoin",
    "usd_value": "46750.63",
    "euro_value": "39596.07",
    "id": "6e937df9-1345-4c2f-8ace-babff0e5108f",

Components Structure

Implementation Files

Use these files to complete the implementation:

• src/components/CryptocurrencyTracker/index.js
• src/components/CryptocurrencyTracker/index.css
• src/components/CryptocurrenciesList/index.js
• src/components/CryptocurrenciesList/index.css
• src/components/CryptocurrencyItem/index.js
• src/components/CryptocurrencyItem/index.css

Quick Tips

Click to view

• To display the animated loader, we need to import the Loader component using the below statement

  import Loader from 'react-loader-spinner'

• In order to display the given animated loader, pass the type and color props to the Loader component with values as Rings and #ffffff, respectively

  <Loader type="Rings" color="#ffffff" height={80} width={80} />

Important Note

The following instructions are required for the tests to pass

• The cryptocurrencies should have the alt as the value of the key currency_name from each cryptocurrency object received in response

• Wrap the Loader component with an HTML container element and add the data-testid attribute value as loader to it as shown below

  <div data-testid="loader">
    <Loader type="Rings" color="#ffffff" height={80} width={80} />
  </div>

Things to Keep in Mind

• All components you implement should go in the src/components directory.
• Don't change the component folder names as those are the files being imported into the tests.
• Do not remove the pre-filled code
