Feeling the confidence to build real-life applications at scale? This is the place where we will make good use of that confidence. Welcome to our first case study, where we will build an e-commerce application with NestJS.

In this chapter, we will take advantage of everything we already know about Rest API, testing, and putting the data modeling constraint in our route, so we can build an application very close to any e-commerce we use daily.
