In the previous part of this series, we learned how to write unit tests in a NestJS project with Prisma. Unit tests help verify if individual components of our system work as expected on their own. However, while useful, they don’t guarantee that our API functions correctly as a whole. In this article, we deal […]
Covering our NestJS application with unit tests can help us create a reliable product. In this article, we introduce the idea behind unit tests and implement them in an application working with Prisma. In this article, we continue the code developed in API with NestJS #33. Managing PostgreSQL relationships with Prisma Introducing unit tests A […]
When managing the architecture of our system, we often deal with sensitive data. It’s our job to ensure they don’t fall into the wrong hands. An excellent example of confidential information is the database password and the Json Web Token secret key. In this article, we explore how we can use the AWS Secrets Manager […]
In the latest articles, we deployed our NestJS application using AWS. However, we’ve been exclusively using the HTTP protocol so far. You probably noticed that almost every website nowadays uses HTTPS. And no wonder, because it solves a bunch of problems and makes surfing the internet more secure. In this article, we prepare our architecture […]
In recent articles, we’ve learned how to deploy our NestJS application with Docker and AWS. In addition, we’ve managed to deploy multiple instances of our API using a load balancer. Still, it was always a fixed number of instances. In this article, we learn how to adapt to traffic by changing the number of deployed […]
In one of the previous parts of this series, we learned how to use the Elastic Container Service to deploy multiple instances of our application. With this architecture, we maintain the target group, where each target is a single instance of our application. Thanks to that, the load balancer can route a particular API request to […]
In this series, we’ve learned how to use the logger built into NestJS. In this article, we learn how to manage the logs our NestJS application produces using Amazon CloudWatch. In this article, we assume you’re familiar with deploying NestJS applications using Amazon Elastic Constainer Service. If you want to know more about this topic, […]
We should closely monitor the state of tests in our NestJS application. In a few previous parts of this series, we’ve used Docker and GitHub actions to design a CI/CD pipeline that automates our deployments. In this article, we avoid deploying faulty code by running unit tests before each pull request automatically. Preparing the Docker […]
In the last two parts of this series, we’ve explained the details of manually deploying our NestJS application with Amazon Elastic Compute Cloud. It’s a great idea to go through the above process by hand to understand it fully. The next step is automating it by implementing Continuous Integration and Continuous Delivery. In this article, […]
In the previous article, we learned how to use the Elastic Container Service (ECS) to deploy a single instance of our application. This time, we take a step further and deploy multiple instances with a load balancer distributing the traffic. Our application might perform as expected on most days. However, there are times, such as […]
