KOA, Node JS, MongoDB, Mocha.
### Existing code:
NOTE: This is an existing project that already has the UI, Database, Database schema and REST JSON schema ready. It also has some KOA models and KOA api skeleton. So you can use all this existing code base.

2) The API return value should be a JSON document containing list of episode schedules for requested date or an error code.
3) Create unit tests for the developed code using Mocha.
