react-currency-converter

Simple currency conversion app, which uses exchanged rates API from exchangeratesapi.io. The app is made with React in a Functional Programming like approach. Unit tests are made with Jest and Enzyme.

Demo

A note:

For the demo website purpose I used mocked data in this repo as since the 1st April 2021, the exchangeratesapi.io requires an API access key to use the service. You can sign up for a free API key or get the paid one on their website (just keep in mind that the free plan uses the http protocol).

When you will have the API access key:

  • add it to the .env file (remember to include the .env in .gitignore) or alternatively set the environment variable on deployment platform
  • read and use it's value as API_ACCESS_KEY variable in the src/App.js file
  • in src/components/DataContorller.js:
    • remove mockData variable,
    • in componentDidMount method:
      • remove this.setState({ data: mockData });
      • uncomment this.loadData() line

UI example:
