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 […]
In the last two parts of this series, we’ve dockerized our NestJS application. The next step is to learn how to deploy it. In this article, we push our Docker image to AWS and deploy it using the Elastic Container Service (ECS). Pushing our Docker image to AWS So far, we’ve built our Docker image locally. […]
The previous article taught us how to use Docker and Docker Compose with NestJS. In this article, we expand our knowledge by applying various tricks and tips on increasing the development experience with Docker and Docker Compose. Check out this repository if you want to see the full code for this article. Building the Docker […]
So far, in this series of articles, we’ve been using Docker to run various services our NestJS application depends on. Some good examples are PostgreSQL and Redis. We can take it a step further and put our NestJS application into a Docker container as well. It can be very useful when looking into deploying our […]
It’s a very common case to need to combine multiple related tables. In SQL, we can do that using a join statement. Therefore, this article explains various types of joins along with real-life examples. Inner joins A few articles ago, we defined the users and posts tables.

CREATE TABLE users ( id int GENERATED BY DEFAULT AS IDENTITY PRIMARY KEY, email text NOT NULL UNIQUE, name text NOT NULL, password text NOT NULL, address_id int UNIQUE REFERENCES addresses(id) ); CREATE TABLE posts ( id int GENERATED BY DEFAULT AS IDENTITY PRIMARY KEY, title text NOT NULL, post_content text NOT NULL, author_id int REFERENCES users(id) NOT NULL ); |
It’s typical to retrieve a particular post along […]
By default, NestJS uses Express under the hood. Moreover, since Express is very popular, NestJS can choose from a broad set of compatible third-party solutions. A significant advantage of NestJS is that it is framework-independent. Instead of using Express, we can use an adapter using another library with a similar request/response pipeline. The most popular […]
