||Something I Overheard at MWLUG
This is a quick post, covering something I overheard while at MWLUG and comes back to some application architectural principles which I have a bit of a passion for. Read on at your own peril
I added a bit from a tweet by Tony McGuckin about the XPages runtime’s components.
Back to the Grind After MWLUG
There’s an intersting slump I experience after getting back from a conference. Not only do I get to clear out of the mountain of things that seem to crop up only while I’m out of the office, but it seems that I’m able to come away from such a gathering with other developers with lots of great ideas for both my growth as a developer but also for what I’m able to accomplish for my company and its users that it’s a nearly unbearable amount to be able to extract from my own head, but I try. For this last week though, I just worked the tasks at hand.
A Funny Thing
While at MWLUG, I overheard someone make a reference to people “not liking POST” as an HTTP request. I’m fairly certain it may have been said in jest as a blog post I wrote previously talked about “classical” AJAX-y requests containing markup (specifically analagous to an XPages partial refresh event, which fires a dojo.xhrPost that returns the HTML content of the selected refreshId and re-injects the content to the page). So here’s a reminder to all, XPages gives us:
- an application runtime (JSF)
- a striped database (though for performance it’s best to separate it)
- with a greatly convenient security model (that makes it very easy to map roles and groups across applications)
- and a bunch of OoB (out of the box) controls that aid in RAD and have some excellent hooks to automate a large number of functions (ExtLib Relational controls, for instance)
As Tony McGuckin pointed out on Twitter, there’s more to the XPages runtime than just the JSF runtime components. Since it’s a larger list than my couple of bullet points, I’ll let the tweet and screen shot from the liked XPages Masterclass video do the talking.
The Screen Shot
My Beef With Transporting Markup
My list above of what XPages provides us lists the controls that we most often associate as being “XPages” (specifically the design elements of XPages and Custom Controls, along with the xp and xe controls) at the end. My approach is opinionated in the absolute segregation of front-end and back-end, but it uses the application runtime provided by XPages (and its JSF implementation) to provide a great experience with excellent results. The OoB elements give us one way of doing things, so since it bugs me, I’m going a different way, without issue.
Transporting markup in our post-page load XHRs is inefficient; regardless of whether we call them AJAX calls, partial refreshes, or whatever. That’s my bottom line. I don’t think POST as an HTTP method is inferior (they’re just HTTP methods), but to add to a request’s body content, just so we can get a small data update in the screen, when we could otherwise have our data providing the same response just in how we build our URI from a simple GET, the logic seems clear to me.
What to Do About It
As my demo application has been showing, I’ve been going the direction of a front-end heavy app (AngularJS app in the UI) with HTTP servlet RESTful API driven data access. This doesn’t necesssarily need an XPages design element (root XPage and Custom Control) since it can/is served from the WebContent directory. For any still wondering, yes I do continue development on and maintain applications that aren’t entirely “my way” when it comes to what are already in use. I’ve refactored core code when able (I’ve seen some scary SSJS libraries and vanquished as many beasts as I’ve been able to) because I firmly believe in keeping core business logic separate from UI logic.
That being said, my advice to any in a “normal” XPages context is embrace the JSON-RPC control and Java beans (managed or POJO). If your business logic is driven inside a controller class, it can just as easily be invoked from a bean or from a servlet (or from SSJS inside a JSON-RPC’s method script). If Java isn’t your thing (if you’re still learning, and you should embrace your JEE stack), the JSON-RPC control lets you accomplish most of the same task of exposing server-side operations and logic, with minimal overhead, to the client-side (browser) for CSJS access; it’s a win-win either way.
In Case You Missed It…
My last post, recapping my session at MWLUG, managed to get missed in my first tweet of the link. I updated the previous post (announcing my session at MWLUG) with a link at the top, but some may have missed it. Please check it out, there’s a link to my slide deck, GitHub repository with my configs, screen shots of my configs in use, and (you guessed it) my slide deck in PDF and PPTX formats.

I’m Back What Can I Say? In Case You Missed It If you find yourself asking “where was Eric?”, this should summarize it all: Instead of trying to do everything all summer, I tend to take a break from blogging and a lot of open source endeavors over the summer. It means I can focus on family time along with yard and house projects. Ah... Summer That’s all paid off and, with fall fast approaching, I’ve found myself wanting to start those things back up; ramping up into winter when

Intro It’s time to clear some of the backlog. I started this post a few months back and it should probably be sent on its way to clear the pile of drafts I haven’t finished yet… 🤔 I have a bit of a passion for open source software. My preferred distribution of Linux has been Ubuntu since 4.10, the Warty Warthog (I was even a minor contributor on a short lived, wildly popular project that aimed at improving the Ubuntu experience early on), I’ve enjoyed most open source projects I’ve

Docker If you have been living under a rock, Docker is pretty much amazing. If you haven’t been living under a rock, you may be getting used to the idea of Docker, but still have the occasional question. I’ve found myself using Docker in increasing amounts and complexity over the last year or so. I’ve recently decided to start recording some of the tasks I’ve found useful, some of which may be less familiar to a beginner. If you’re so inclined, check out the playlist, embedded here.
Notes in 9: Dev Tools Grab Bg|
Tue, Apr 4th 2017 1:00p Eric McCormick
Intro I’m on Notes in 9 again, with a “grab bag” of a couple of tools I’ve put together recently that may be of a varying degree of useful for other Domino + XPages developers. You don’t need these to do development, but for the right person, they may help with their development workflow. Also of note, with the upgrade to Swiper with the FP8 release of Notes + Domino Designer, the limitations previously mentioned are no longer there! This means that my second tool I talked about, node-

Per usual, I’ve had a little break between things and decided to catch up with a bit of a summary of some recent things that each didn’t necessitate their own post.
2017 IBM Champion
For starters, I’m honored to be named an IBM Champion in Collaboration Solutions (/ Social Business) for the third time. This would be a hat trick in (ice) hockey 🏒. I’m happy to be recognized with a group of people, developers and more, who are passionate about both their work and the plat

If you read my blog for any of the Saga of Servlets series, then I hope that you’re excited I’m returning to the application I put together for it. This time, it’s as a conversation piece in regards to some of the build process modernization I engaged in recently, in order to unify the code base in its git repository. In any case, it’s helping pave the way forward before I update some of the back-end elements, when it will again be a talking point for some additional rework and

This one might be slight departure from my usual, but those that have followed my blogging this past year will have noticed a bit more of a leaning towards DevOps in some of my posts. This echoes a lot of what I’ve been concluding as increasingly a necessary part of development; that we need to consider a picture large enough to encompass the themes surrounding development functions and, like any good developer (DRY ~= “lazy”), automate the heck out of it.
I had p

Every so often, it’s good to reassess one’s position. This is good from both a standpoint of being inquisitive and even interrogative, but when it comes to the ever changing landscape of the front-end development space, it’s not only inevitable, but must be embraced for what feels the need to “stay afloat”. I’m changing theme of my blog, hopefully for the better. The previous theme was good and did a great job of getting things started, but while I had forked a copy of a good

If you’re just here to learn a little about how to “squash” commits with git, skip down a ways. Otherwise, hold on, and I will catch you up on a couple of personal notes before we get there.
On the Blog
It’s been a little while since I blogged last. This has been due to a combination of reasons; specifically, I’ve been busy with:
my family, it was the end of summer with lots of things going on
a number of projects around the house (a deck removal and basement remodel
