DatoFacil
This Responsive App uses the open-data API from Argentina’s Government.
It’s developed with React using libraries like Material UI (a Google’s Material Design implementation) and Recharts (a wrapper for the D3 charts library).
Though the main data is fetched from an external API, it uses also its own Node.js API to minimize the transferred data to the client side. It also provides descriptions for the datasets. Those descriptions are stored in a PostgreSQL table. Since search engines indexation is important, DatoFacil implements Server Side Rendering.
