Closing

Some final words after finishing the Core module

I hope you have enjoyed your time here learning how to develop a somewhat real application and acquired useful knowledge and skills while doing so. The intention is not only that you learn, but also that you have fun doing so, and this is why the course is 100% practical. It can be very tedious and bothersome to learn something in a way that is completely abstract and disconnected from reality. So, once again, thank you for taking this course with me and I hope you feel that your time was well spent.

Still, there is a lot more to learn. There are many other modules present in the full course that may further expand your knowledge. If you are interested, you may acquire it for an accessible price on Udemy. Just to recap, this is the full content

• Core module - Backend Development with NestJS

• Improvements/Tips module

• Extra module 1 - Authentication/Authorization

• Extra module 2 - Exception Filters

• Extra module 3 - OpenAPI Specification

• Extra module 4 - File Management

• Extra module 5 - Advanced Querying

• Extra module 6 - Automated Testing

• Parallel module - Prisma

As a last word, I encourage you to take ownership of this project. If there's something you didn't understand fully, study once again the respective lesson and try to fiddle with the code in order to see what's happening. Try to think of different, maybe even better solutions to the situations being tackled here. Finally, try to think of new, interesting functionalities to the system. What if the user actually had the balance attribute that would be altered when an order is paid? What would be the new logic necessary to make this consistent? There are many different things you could think of to play with in the code, this is just an example.

With all this said, thank you once again for participating in the course, and I hope it can help you in some way. Always remember that you can go back to it whenever you wish. Best regards.
