Beware of Backpressure

One of my junior dev was frustrated today. He was supposed to read from a file stream with NodeJS, piping that into the database. However, he got errors thrown everywhere when dealing with larger files. I helped him identified the problem. He had been dumping async calls (the database insertion) faster than the call could be handled. I remotely remember I run into a similar issue years ago when I wrote a web scraper in NodeJS.

Compress Url Parameters Without a Storage

In advertising and other online marketing fields, a common practice is to distribute URLs to the clients so that they can report user action through a simple GET request.

I also wrote a blog about Vue3 changes on its new functional APIs.

Rethink The Clean Architecture

The Clean Architecture is more like a fantasy. It is like a wonderland we will never be in. I would enjoy and appreciate a work where all business domains, application domains, and transports and UIs, etc. are all orthogonal. In reality, they are all wired together like a mess. It is no mess created by engineer though. The world is chaotic by itself, so do all the business around it. Imagine your boss tell your team to add a new button to your website, and you find your business rule doesn’t cover this button what so ever, so you have to update your JSON API, add new test cases, and add new event to your event sourcing bus, and change whatever is affected all the way down to the database level.

Unboxing Taylor Otwell's Laravel Cloud

Taylor Otwell, the author of Laravel, recently put up a public copy of his unfinished work Laravel Cloud in GitHub. It was taken down by himself briefly after, due to what he described as “too much BS”. Forks are still available everywhere though. Here is my fork. I cloned the repository and skimmed through most of the classes. Here are my takeaways. Dependency Injection is used very lightly. The service container is mostly underfilled.
