We’re going to build a URL shortening API that’s meant to be used as an internal tool for the company you work for.

E.g. Imagine you work for a startup and you need a URL shortening tool, and you decide to build one instead of paying for an existing solution.

Topics covered:

• REST endpoints with CRUD functionality

• Paginating and filtering a GET request that returns a list

• Validation with DTOs and pipes

• Persisting data to a database

• Basic API key authentication using guards

• Using the config module

• Unit testing, integration testing and end-to-end testing
