.NET makes it super simple to update the dependencies of a project. If you are following a solution structure like Clean Architecture where the Web project should not be referenced by the Core project or you have created your own solution structure that requires certain projects do not reference another project then you might need a way to avoid having developers incorrectly adding dependencies. The diagram above gives a high-level view of all project dependencies in a Clean Architecture solution. Built with Excalidraw. ...

A few weeks ago I came across a blog post from Aaron Francis in which he talks about creating efficient pagination using deferred joins. A technique he remembered reading in High Performance MySQL: Proven Strategies for Operating at Scale. The idea is that without deferred joins pagination queries can impact response time. Pagination is done using an OFFSET to skip over a number of records, however, even though the results are skipped, the database must still fetch those records. Meaning we are reading data from the disk and immediately discarding it. This is an inefficient process and is what causes pagination performance to degrade as you paginate over more records. ...

It has been a while since I blogged about JSON:API. In my last post on JSON:API I covered how to create new resources. In today’s post, I want to go over how I expose pagination links. Pagination links allow a client to page through a collection of resources. A shift of control from the client back to the server. Here is an example of a possible JSON:API response that includes pagination links. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 { "data": [ { // omitted for brevity } ], "links": { "up": "http://example.com/", "self": "http://example.com/articles?page[number]=3&page[size]=1", "first": "http://example.com/articles?page[number]=1&page[size]=1", "prev": "http://example.com/articles?page[number]=2&page[size]=1", "next": "http://example.com/articles?page[number]=4&page[size]=1", "last": "http://example.com/articles?page[number]=13&page[size]=1" } } As you can see, along with the data object, the API responses included a Links object, within the Links object, you can find links for up, self, first, prev, next, and last. These are all relationship name as defined in Link Relations by the Internet Assigned Numbers Authority (IANA). ...

Over the last few years, our industry has moved away from monolith architectures to microservice architectures. For a good number of reasons, this trend continues to remain strong. One issue you may encounter with creating microservices if you are not using a monorepo is that you may have to build a new project whenever you need to add a new microservice to your app ecosystem. Creating a new project may include creating new repositories in Bitbucket/Github, configuring a continuous integration pipeline, adding build/deploy scripts, building the project based on some folder structure that has been determined by the team. It can also involve configuring how the service captures logs, communicating with other services, exposing an Open API definition, configuring a docker file, having a helm chart to deploy to k8s, installing external packages, and so on. ...

Development tools are an essential part of our job, they make us work smarter not harder, they simplify processes and make us more productive. In this post, I want to share some tools that I have found over the years that have made my job easier. If you have a similar experience with a tool that is not listed here, then I would love you hear from you. Grepapp ...
