• Component Queries Metadata Appears To Be Broken When The Ivy Renderer Is Enabled In Angular 9.0.0-rc.2

  Posted on Nov 19, 2019 at 7:55 AM

  @All, It looks like it was a problem with my angular.json configuration. For reasons I don't fully understand (read: not at all), it seems that it was breaking because I didn't have the aot (ahead of time) compiling setting in the base build configuration. Jeffrey Bosch figured it out,... read more »

• Serializing A MySQL RecordSet As A Set Of INSERT Statements Using Lucee CFML 5.2.9.40

  Posted on Nov 19, 2019 at 5:21 AM

  @Señor, I use MySQL 1) out of habit, and 2) it's what this app has used for the past 7-years. What's the high-level overview of MariaDB? I believe the last I heard, it's just a drop-in replacement for MySQL. Is it just supposed to be faster, but all the same API?... read more »

• Component View-Template Fragments Retain Bindings And Can Be Moved Around In The DOM In Angular 9.0.0-rc.2

  Posted on Nov 18, 2019 at 8:04 AM

  @Charles, Yeah, this stuff is pretty cool. I started thinking about this because I got curious about creating an HTML Dropdown menu in which the "menu" portion is actually appended to the body so that it can be z-index 'd above the rest of the content. This is akin to how the ... read more »

• Collapsing Sticky Elements And Maintaining Scroll Offsets In Angular 9.0.0-rc.2

  Posted on Nov 18, 2019 at 7:53 AM

  @All, As a quick follow-up to this, I wanted to explore a somewhat-related topic of maintaining the user's current "scroll offset" even when content is added above the viewport: https://www.bennadel.com/blog/3724-maintaining-scroll-offsets-when-adding-content-above-the-user-s-v... read more »

• Component Queries Metadata Appears To Be Broken When The Ivy Renderer Is Enabled In Angular 9.0.0-rc.2

  Posted on Nov 17, 2019 at 7:39 AM

  @All, For completeness, here's my package.json (currently installed Angular 9.0.0-rc.2: { "name": "webpack4-angular9-cli", "version": "0.0.0", "scripts": { "build": "ng build --prod", "ng": "ng"... read more »

• Component Queries Metadata Appears To Be Broken When The Ivy Renderer Is Enabled In Angular 9.0.0-rc.2

  Posted on Nov 17, 2019 at 7:35 AM

  @All, To my surprise, my demo actually worked when I pushed it to GitHub pages. The only difference there is that I'm using the --prod flag when doing the build (as opposed to using the dev-server locally). I've added a note to the top of the blog post. So, perhaps this is a bug in the... read more »

• Closure Variable-Access Changes With Function Expressions vs. Function Declarations In Lucee CFML 5.3.3.62

  Posted on Nov 16, 2019 at 2:09 PM

  @Andrew, The plot thickens! I'll see if I can find a Lucee ticket about this then. Maybe someone is already tracking it.... read more »

• Using CSS Overscroll-Behavior To Prevent Scrolling Of Parent Containers From Within Overflow Containers

  Posted on Nov 16, 2019 at 5:19 AM

  @Ted, That said, the beauty of CSS like this is that you can use it a "progressive enhancement" feature. Meaning, you can put it in, and then users who have browsers that support it will get a slightly better experience; and, users who have browsers that do not support it, wi... read more »

• Creating A "position: sticky" Header Component Using IntersectionObserver In Angular 7.2.11

  Posted on Nov 14, 2019 at 7:36 AM

  @All, On a related note, I just tried to re-create the sticky-header experience that GitHub has on their PR page: https://www.bennadel.com/blog/3720-collapsing-sticky-elements-and-maintaining-scroll-offsets-in-angular-9-0-0-rc-2.htm This uses a position: sticky header; then, adjusts t... read more »

• ColdFusion Performance Experiment: Caching Per-Application Settings In Lucee CFML 5.3.3.62

  Posted on Nov 13, 2019 at 10:12 AM

  @Tom, Yeah, you basically never need to think about it :D which is nice. The only time it really ever matters is if you need to something non-standard , like turn on/off session management on a per-request basis. It's very rare that I ever think about it.... read more »

• ColdFusion Performance Experiment: Caching Per-Application Settings In Lucee CFML 5.3.3.62

  Posted on Nov 13, 2019 at 10:03 AM

  @Tom, Great question. You're just conflating two like-named things (naming for the win!). The application scope persists during the entire life of the application. However, the Application.cfc component gets reinstantiated on every single request. Now, that's not to say that ... read more »

• Replacing ColdFusion Query-of-Query (QoQ) INNER JOIN And LEFT OUTER JOIN With Array Functions In Lucee CFML 5.3.3.62

  Posted on Nov 13, 2019 at 8:17 AM

  @Charles, My pleasure! Sometimes, it's a fine-line between "clever code" and "hard to read code". So, use this is caution, I would say. I find that I use this most when I am setting a key into some sort of Struct / Object. You can even do this in something like a retur... read more »

• Replacing ColdFusion Query-of-Query (QoQ) INNER JOIN And LEFT OUTER JOIN With Array Functions In Lucee CFML 5.3.3.62

  Posted on Nov 13, 2019 at 7:21 AM

  @Charles, In the screenshot, I was just collapsing the other Struct instances so they didn't take up as much room. Sorry, I should have mentioned that in the write-up. JavaScript doesn't have the Elvis operator; but, it does sort-of allow for the same type of operation using the || (OR... read more »

• Confusion Over this.mappings And expandPath() Not Working In Lucee CFML 5.3.3.62

  Posted on Nov 11, 2019 at 7:39 AM

  @All, Here is a ticket that touches on this topic: https://luceeserver.atlassian.net/browse/LDEV-1718 And, ironically , I just found a message on this blog from 2013 pointing out mappings fail if the folder doesn't exist (from Sumit Verma): One thing to be careful about exp... read more »

  @All, A couple of people on Twitter asked me about the relative performance of ColdFusion Query-of-Queries and Array-based data collation. To be clear, both options are fast ; but, Array-based methods are faster. In most context, there is not going to be any pragmatic difference. Howeve... read more »

  @Tim, Great point. I feeeeel like I have seen this affect on a mobile device; though, I will confirm that my approach here, as you say, does not work on mobile :( Good luck! If you ever write it down, I'd love for you to drop a link to it.... read more »
