Running and testing our first microservice

We’re not going to write any unit or integrate tests in this chapter. In Chapter 11, where we’ll dive into the details of those topics. For this chapter, we’ll do manual testing via Postman. To run our application, follow these steps:

1. Download Ch05 from our GitHub repository.
2. Open the project (Ch05) via Visual Studio Code.
3. Go to Terminal | New Terminal.
4. Run the npm install command from the Ch05 folder to load the required packages.
5. Change directories to src (using the cd src command).
6. Run the node index.js command. Mongo should be installed before you run this command. Check out Chapter 4 for more information about the installation process for Mongo.
7. Open Postman.

In the next few subsections, we’ll test our endpoints one by one.
