Thanks for the kind words Ben! I too miss the old react with life cycle hooks, i know there are better ways to write the sample which I did but it should be the job of the framework to make right approach easy and bad approach hard.... read more

@Hassam, ❤️ Very cool ❤️ I really appreciate you putting that together. It took me a minute or two, looking at the code, to see what was going on. The Hooks approach to building React application really requires me to turn my brain a bit inside out. I see that you have three different hooks to get t... read more

There is REAL tension between wanting to be cool - not having much in the way of (visible) boilerplate, dependencies, etc. - and wanting to scale to the real world, with its costs. In olden times, you had Steve Yegge on the value of simple languages (Javascript, Python), and Joel Spolsky on the valu... read more

@Hassam, I've only played with earlier versions of React that had life-cycle methods (like componentWillMount() and stuff). In that case, it feels like a relatively similar approach. When it comes to "new" React with Hooks, I don't know how it would work. I feel like you'd have to create a special E... read more

@Dan, I think we actually had this very same conversation back in 2015 🤣 I'm not sure how much of that is still an issue.

@Ben, Things may have changed in ACF, so I might be wrong, but I think you have some potential issues that would make this not thread safe. I know that in ACF, the closure is used to hold references to the current request, so if any of the variables your closure is relying on die after the request, ... read more

Comment posted November 15, 2022
@Ben, "I like to avoid nullable columns wherever possible". Me too, absolutely. Hate the bloody things. For var/chars I never use them, because I've never come across (others will have I suppose) the need to know whether an empty string is 'really empty' or 'don't know yet'. But they're hard to avoi... read more

Comment posted November 15, 2022
@Ian, While I love the idea of not doing a "hard delete", I do still want to move the "deleted" row out of the table. What I have found is that with "soft deletes", it's harder to make indexes that can enforce uniqueness. What I would love to do is create "archive table", that receive a copy of the ... read more

@SCOTT, I also do both, and like you only audit a few 'major' tables in any given system.

@Scott, I've dabbled a bit with an "audit log" in an application many years ago; but, I haven't tried it since. That said, I have added many piece-meal log tables to track some "delete actions", mostly - to your point - so the Support team can point to something and say, "Actually, Mr. Pink, on your... read more

I used to always add dtUpdated columns in all my tables too, but did not usually show that to users. However, in recent years, I don't add that column automatically to tables anymore, because I noticed that just having an update date was not very helpful to me. Now if a table is going to hold record... read more

@Mark, Changing infrastructure is a fascinating topic unto itself.

Should have checked before posting - on my last point I made an incorrect assumption - there is no conversion performed for the replacement string. (At least in Lucee; I'm not installing CF to test.)

@Peter, I'll have to plead ignorance on the POSIX vs Apache ORO engine stuff. I honestly don't really even know what POSIX is exactly.
