I have always wanted a photo slideshow feed from the photos stored on my NAS. While Synology Photos includes a slideshow feature, it is limited: it only displays photos in descending order (newest to oldest). This means I rarely see photos from years ago.
As a long-time Synology user with thousands of memories stored in my NAS device, I decided to take matters into my own hands and I developed a web-based slideshow application that displays photos at random.

Continue readingI upgraded my 2019 MacBook Pro Intel Core i7 to the newer 2024 MacBook Pro M4 Max. Before upgrading I was building Docker images in my Intel Mac and deploying a Next.js app and a .NET Core API without any issues to my Synology NAS. However, after getting the new Apple Silicon Mac, I started having Issues deploying the Next.js Docker Image to Synology Container Manager.
Continue readingUp to this point I have only used AI to generate code snippets, either via Gemini web or the Codeium extension on VS Code/Rider. Recently, I decided to give Trae AI IDE a try and as I was updating my portfolio site at esausilva.dev, a brilliant idea sparked and found a use-case to fully utilize the power of AI. That is when I had my AHA moment, my AI enlightening moment.
Continue readingImplementing idempotency in .NET Core can be accomplished with a filter, which I will cover at a high level.
Putting it simply, idempotency is the concept of executing an operation multiple times and getting the same result back, given the same input parameters for each request. In our case, we will be setting up idempotency for an API endpoint.
Continue readingWe have an API that handles ~45k monthly requests that was, at times, responding strangely. I suspected it was related to the .NET Core service lifetimes.
The symptoms in question were that out of the blue, the API response body had a status code of 409 with a message of invalid user-provided values, however, the actual HTTP response status code was 200.
Continue readingPostman is a powerful tool for testing and working with APIs. In this blog post, I will describe some Postman tips for better API testing that I have used for quite some time and have helped tremendously.
Continue readingCalling an authenticated API from Next.js server side is a little different than calling it from the client side and concerning authentication cookies.
Continue readingWhether calling the external API costs money or mocking desired behavior to code specific business rules. Sometimes external APIs could be mocked during the development of services or APIs. I believe this is an important strategy in every developer’s toolbox.
Continue readingThis article will focus on handling custom exceptions for flow control on .NET with a global exception handler and return a problem details object.
Having said that. There are, for the most part, two schools of thought. One where it is OK to throw a (custom) exception to control flow. i.e. Throw a UserNotFoundException when a user is not found. The second is implementing the Result Pattern where you return a Success or an Error to control the flow. i.e. Result.UserNotFound.
