Overview
AWS Lambda function triggered weekly via CloudWatch Events to update a text file containing the global top five songs on Spotify for the week. This function utilizes Java, JGit, and the Spotify API
Description
This function was created as a demonstration of a simple AWS Lambda function that clones a repository into the temporary files, reads the data, and updates a file based upon the current data and the Spotify data. The Spotify data is obtained by handing over developer credentials to the Spotify API in a query for the current Top Global Charts data. This data is parsed through and the top five songs are extracted.
