warp VS pkg

jpackage is not the only tool for bundling Java. There is also warp-packer, an open-source tool to create self-contained binary applications from Node.js, .NET Core, and Java. warp-packer requires a similar workflow to Method 2, where you create your modified Java Runtime image and an executable script before bundling everything together into an executable.

https://github.com/dgiagio/warp just googled it, no direct experience

KeenWrite is my free, open-source, cross-platform desktop Markdown text editor developed using JavaFX. The installer script uses warp-packer to create installation-free self-extracting binaries for Windows and Linux.

My desktop text editor[1] is written using JavaFX and leans on Warp Packer[2] to create installer-free, multi-platform executable binaries (without jlink). A user contributed a new dark theme[3], which blends nicely with the desktop.

The JavaFX-based WebView (an HTML rendering component) is lauded, but has no direct API to control the scroll position and is itself a memory hog. Scrolling must be handled through JavaScript, and that indirection is as unwieldy as you can probably imagine. FlyingSaucer is a workable alternative to WebView, but comes with numerous technical issues that rear themselves when embedding a Swing widget inside a JavaFX application---as I discovered during development.

Were I to start from scratch, I would definitely seek out alternative cross-platform programming languages for desktop application development.

"Java -- possible, but you'll need a startup script to just call java -jar some-tool.jar; (also not a good fit for short-lived tools, mainly due to startup times;)"

Two technologies to look at:

* Warp Packer -- https://github.com/dgiagio/warp/

* Liberica Native Image Kit -- https://bell-sw.com/pages/liberica-native-image-kit/

Warp Packer bundles my JavaFX desktop application, KeenWrite into single binary executable files:

* https://github.com/DaveJarvis/keenwrite/releases/download/2.... (Linux)

* https://github.com/DaveJarvis/keenwrite/releases/download/2.... (Windows)

* https://github.com/DaveJarvis/keenwrite/releases/download/2....

The start-up time for the first launch of the .bin or .exe is slow because it unpacks to a user directory. Subsequent starts are fine enough, even when running from the command-line as a short-lived task. Here's the script that creates the self-contained executable files:

https://github.com/DaveJarvis/keenwrite/blob/master/installe...

To create a release for all three files, I run a single shell script from a build machine:

https://github.com/DaveJarvis/keenwrite/blob/master/release....

I could probably generate a binary for MacOS, but not enough people have asked.

I don't remember the details, and cannot find my notes on vercel/pkg. But looking at https://github.com/vercel/pkg right now I see the project has been deprecated in favour of single-executable-applications

> Standalone CLI — we haven’t worked on a standalone CLI for the new engine yet, but will absolutely have it before the v4.0 release.

This part is the most exciting to me. Given the rest of the release announcement, I'm assuming this means that it'll be built in Rust rather than embed Node. While I'm not a Rust zealot of anything, I'm very partial to not embedding Node. Particularly when it depends on using Vercel's now-abandoned pkg[1] tool.`

The npm package called "pkg" seems to be the standard for packaging NodeJS applications

https://www.npmjs.com/package/pkg

Unfortunately you also need to bundle all your code into a single file for it to work, but you can use any bundler (webpack, parcel, etc) you want at least

Nodejs support for "single executable applications" is getting there - this issue below is preventing wider adoption at the moment:

"The single executable application feature currently only supports running a single embedded script using the CommonJS module system."

https://nodejs.org/api/single-executable-applications.html

Should be an awesome game changer for node.js when the feature gets rounded out.

Also check out vercel's `pkg`: https://github.com/vercel/pkg/issues/1291

Yes, you can. Check out pkg for a fun option, which can package up your project and Node.js into a single executable.

Further, you could experiment with the pkg tool that allows you to package up Node JS, your source, and your dependencies into one single executable for easy distribution.

package the app using https://github.com/vercel/pkg and use a smaller base image like alpine, busybox or even scratch (if possible)
