the latest version of Porffor features ESM support! it not only removes needing a bundler beforehand but also makes compilation much faster as we can split C across modules

compilation time, selfhosted
react 17.31s → 4.16s (4.2x)
svelte 7.30s → 2.21s (3.3x)
preact 5.17s → 1.63s (3.2x)
solid 9.95s → 2.80s (3.6x)

Porffor alpha is out! It represents a new phase of the project where real-world dependencies are beginning to work and Node compatibility is the main bottleneck. To be clear, it still likely won't work with your app yet, but it is much closer than before. Recap here: honk.foo/porffor-alpha/

Porffor goes alpha August 11th

A self-hosting and rewritten Porffor launches in SF next month!

Alright, I didn't so much learn @gleam.run as I did play around with Porffor (JS to native code compiler by @honk.foo) 🧵

also a fun side project I've been hacking on and off for about half a year: autolrc.honk.foo totally didn't just make a landing site to test porffor rewrite in "prod". nope, nuh uh, no way

Porffor is now self-hosted, meaning it compiles itself with itself! This is made possible by Porffor's new rewrite, reducing its lines of code by >50% and making C output up to 5x more efficient! Here you can see the stats before and after the rewrite for Porffor itself:

Porffor selfhost rewrite graphs, before vs after.

bundle lines 40.4K→24.7K (1.6x smaller)
bundle size 2.4MB→2.0MB (1.2x smaller)

C lines 1.6M→289.0K (5.5x smaller)
C size 70.4MB→12.3MB (5.7x smaller)

debug compile time 5.0s→1.2s (4.1x faster)
release compile time 143.2s→37.1s (3.9x faster)

debug binary size 52.4MB→13.6MB (3.8x smaller)
release binary size 14.1MB→4.6MB (3.1x smaller).

(very!) early preview for a new experimental threading Porffor api. it enables intentionally low level concurrency to (try to) enable the most efficient communication feasible. here are 1 million threads alive simultaneously using only ~16gb. 16kb/thread, <1us start avg.

A graph with RSS as Y axis and threads as X axis. It increases linearly bottom left to top right. Footer shows: "1.00M threads · 15.9 GB · 16 KB/thread · 0.7 µs/start"

optimized selfhosted porffor binary is now <20mb and only takes ~1 minute to compile (>90% clang). (% change is vs debug binary) still buggy though. also still too big ;)

cleaning up code directly correlates to smaller (unoptimized!) selfhosted binary size 😇 (the ~release binary size is much much smaller)
