An R Shiny app to display our CRAP project water quality data
The deployed API is available on (this also has a cold start of ~60 seconds if it hasn't be used for a while)

The Plumber API is designed to read and process data for the map, providing a seamless integration between data processing and frontend visualization. This API serves as the backend data processor and handler for requests coming from the frontend application.
The data is loaded as usual from the /data directory by api/api.R. This script handles all the necessary data transformations to prepare it for use by the frontend. The server.R creates an API endpoint so the processed data can be served on demand to populate the map.
Currently the data is still managed manually by the csv /data. To update it, upload the latest CSV. Eventually we can store this data in a database, and provide API endpoints which allow new data to be added on a case by case basis, rather than overwriting the whole file.
To start the API server, execute the following command from the terminal, ensuring you are in the root directory of the project:
Rscript api/server.R
