React App without backend persistence. Users can view earthquakes from around the world on a Google map and filter based on specific times and earthquake magnitude. Earthquake information is from the USGS API. You can read about how I implemented the Google Map here on my blog.
This was my first React App, so it is fairly simple. The components are EarthquakesContainer, which has all other components as children. The children are EarthquakesForm with siblings EarthquakesList (which I no longer use) and EarthquakesMap (which overtook made EarthquakesList obsolete). EarthquakesMap has one child, EarthquakesItem which is the information that is displayed when a user clicks on the earthquake icon on the map.
EarthquakesContainer makes use of the google-maps-react component. For the map I utilized a terrain Google Map, Markers, PopUps and a Heatmap layer. Google Maps API documentation here.
Each earthquake data point the map receives is plotted on the map based on its coordinates, weighted (for Heatmap) based on its magnitude, and given a title (for popup).
Services holds the fetch requests to the USGS API. There fetchQuakes (which returns all earthquakes for last 30 days) and searchQuakes (which returns all earthquakes that meet user-specified criteria) functions. The results of the fetch requests are stored in the quakes state in the EarthquakesContainer.
