Good job creating your first API Cholpon! Just remember going forward to make use of query params instead of creating one endpoint for each filter

You don't need to include the compiled files, you can add it to your gitignore file

These could all be query params under the /albums endpoint, no need to create different endpoints for each filter. This way you also have the possibility to chain filters, e.g. if you want to filter on year and category
