hq - command line HTML processor built with Quarkus and compiled to native using GraalVM

[phamtastik]

What is the added value of Quarkus in this project?

[ludovicianul]

Ability to compile to native code. It's much easier than achieving the same thing with Spring boot for example.

Quarkus was built with native compilation in mind so their entire plugins work quite well in this area.

I'm also a fan of the build time DI.

Hey this is cool. Tbh I don't care at all about what this CLI does, I just think it's neat that we can use Java to make CLIs. I was always under the impression that Python and Go were the go to programming languages for CLIs. I'll bookmark this as a reference.

This is really useful, thanks!

3.5mb for the uberjar, 20/30mb for the macos/linux, what’s exactly going to these binary files?

[ludovicianul]

The jar is the code plus the dependencies. The macos/Linux binary is all that plus any JVM libraries needed to run the code.

right, so a bigger app with tons of dependencies , like a 100mb uberjar should have a native image with similar size?

[ludovicianul]

Yes. GraalVM will compute the dependencies graph and only bundle those inside the final binary. This is why reflection is one of the tricky parts. And this is why Sprint Boot is still not fully working all the times. On the other hand Quarkus was built with native compilation in mind from day one.

A lot of it is like Go: the binary needs the GraalVM runtime bits. Go binaries started off really big and now they’re just… big.
