Among the technical reasons Domino has enjoyed longevity in the application server market are its stability and reliability. But of course technology changes rapidly and being able to successfully adapt to new trends has also kept Domino relevant over the years. Striking a balance between trendy and relevant is not always obvious but the stewards of Domino have generally taken a conservative approach to introducing and supporting new technology which continues to benefit the product in the immediate and long term.
Very briefly then, beyond the tried-and-true world of Notes client server application development, let's look at three modern technology options developers can choose from in 2021:
1. Domino AppDev Pack (https://doc.cwpcollaboration.com/appdevpack/docs/en/homepage.html)
From the site: "The AppDev Pack primarily adds Node.js support to HCL Domino Server."
2. Domino REST API (Project Keep) (https://opensource.hcltechsw.com/domino-keep-docs/)
From the site: "Domino REST API is designed to re-establish Domino as a world class, modern, standards-compliant, cloud native and enterprise-level collaboration platform. It adds contemporary REST APIs to Notes and Domino, enabling a modern programming experience with the tools of your choice."
This is still in beta but will hopefully be out in Domino 12.0.1 later this fall. Domino has for many years had the ability to offer data via a REST API (Domino Access Services) but Keep modernizes that effort by implementing (among other things) OpenAPI and JWT Authorization. In addition, developers will be able to introduce their own server-side modules called "verticles" as Keep runs on top of Vert.x.
3. Tasklets with DOTS - Domino OSGi Tasklet Service (https://help.hcltechsw.com/domino/12.0.0/admin/wn_dotsredux.html)
From the documentation: "DOTS is a generic Domino add-in task that lets users create Domino server tasks by creating a tasklet container using Java OSGi plugins."
Ok, this is not exactly modern -- DOTS was an OpenNTF project that's been available since Domino 8.5.3. Although officially dropped in the Domino 10/11 era it was recently updated and re-introduced in Domino 12.
Strictly-speaking, DOTS is the Domino server task that manages the tasklets which are Java server-side plugins. Tasklets use a standard mechanism for starting/stopping (OSGi-defined) which makes them similar to Java agents but have the additional benefits of (a) not being tied to a specific .nsf file, (b) not requiring a full JVM reload on every execution and (c) better access to the Domino C API.
How are you developing Domino server-side code these days?

Since many development and administrative tasks in Notes/Domino can conveniently be carried out with great front-end tools like Domino Designer or Administrator, it can sometimes be inconvenient when we're required to use the command line or terminal to get things done. Working with Domino keyrings is a case in point and one of the reasons why I developed Aperture.
Aperture is a lightweight desktop application that allows you to work with those .kyr files without having to resort to the command line. It works with both the KYRTool and OpenSSL to allow you to visually create keyrings, view their contents, create Certificate Signing Requests and several other tasks you'd normally being doing on the command line.
Please visit the Aperture product page for more details: https://www.rhpconsult.com/aperture.html.
As always, comments and suggestions are appreciated!

[Edit February 2020: the LEND product has been renamed to CertMatica]
Version 2.0 of LEND is now available and comes with domain wildcard certificate support via DNS challenge.
Wildcard certificates are convenient particularly in situations where a single Domino server hosts multiple virtual sites, each of which needs SSL/TLS protection. Managing separate certificates for each Domino SSL site in this situation is feasible but not very practical since each one requires its own IP address. A wildcard certificate takes care of that issue and fortunately, Let's Encrypt began offering wildcard certificates earlier this year. However, as of this blog posting, they're only supported with the DNS-01 challenge type.
The DNS challenge feature was interesting to implement because Let's Encrypt DNS challenges do not offer the same level of automation as HTTP challenges. With the DNS challenge, Let's Encrypt servers will query your hosting provider during the challenge/response phase instead of your HTTP server (which is queried when using the HTTP challenge). Since there's no industry-standard way to modify DNS records, the challenge must be entered manually at renewal time, typically using your hosting provider's custom web interface. Fortunately, LEND now has built-in workflow to remind administrators when to do so at renewal time!
Take LEND for a test ride and let me know what you think.
