In this project, we'll build a URL-shortening API tailored as an in-house tool for your company. This is especially handy if you're part of a startup looking to optimize internal processes without the extra expense of third-party services. By crafting our custom solution, we gain flexibility and save on costs.

Topics Covered:

• Creating REST endpoints with CRUD functionality: Learn to set up the backbone of our URL shortener, allowing creation, reading, updating, and deletion of shortened URLs.

• Enhancing GET requests with pagination and filtering: We'll implement methods to manage large sets of shortened URLs efficiently, ensuring quick access and organization.

• Applying validation with DTOs (Data Transfer Objects) and Pipes: Understand how to ensure data integrity and valid requests within our API.

• Persisting data with database integration: Dive into how we store and manage our data reliably using a database.

• Securing our API with basic API key authentication and Guards: Explore how to protect our API from unauthorized access.

• Configuring our service using the Config module: We'll configure our API for different environments with ease and flexibility.

• Testing our application: Grasp the importance and techniques for thorough testing with unit tests, integration tests, and end-to-end tests to ensure reliability.

As we progress, remember that this is more than just code; it's about creating a tool that makes our digital life a bit easier. Let's get started!
