The Weather Comparison App lets you compare the 7-day forecast of multiple cities using the OpenWeatherMap API and OpenCageData's geocoding API. The Express backend is to allow my front end to be ignorant of the APIs being used for geocoding and weather, so I can switch them out more easily if I would like. It also keeps the API keys on the server side, and allows me to use environment variables in my Heroku deployment and keep them secret.

This is a React application, so React and node.js are required to run it. You will also need API keys for the OpenWeatherMap API and for OpenCageData's geocoding API. Once you have your API keys, add them to 'src/config/dev.js' with the following format:

// dev.js

module.exports = {
    OWMAppId: <your-id-string>,
    openCageApiKey: <your-id-string>
};

In the project directory, first run:
