Loading The Media Collection

For this assignment, you are tasked with writing code to load data from a set of CSV files.

• Use the example loader file at libraries/src/loaders/anthony_mays_loader.ts to make your own unique copy of the loader.
• Implement the loadMediaItems method by loading the data from the data/media_items.csv file.

To try out the app with your loader, you can run the following command.

npm run compile
npm start -- --loader yourLoaderNameHere

Before submitting your work, be sure to run the tests.

npm run test

Extra credit

For additional credit on this assignment, combine the credits with the media items you loaded by modifying the loadData method. You can test that you've loaded everything correctly by using this special command:

LOADER_NAME=yourLoaderNameHere npm run test
