Porffor  (poor-for)

An ahead-of-time JavaScript compiler

curl -fsSL https://porffor.dev/install.sh | sh

$ cat hello.js
console.log('hello world!');
$ porf hello.js -o hello
[105ms] compiled hello.js -> hello (33.7KB)
$ ./hello
hello world!

Porffor is a 100% AOT compiled JS engine/runtime. There is nothing interpreted or compiled just-in-time. Porffor compiles JS to C (with an IR inbetween). We chose this approach because:

• it can be used essentially everywhere
• is relatively easy to emit and compile
• it avoids directly depending on a backend like LLVM or Cranelift
• is easily modifiable post-compile for diverse environments

Versioning

Porffor releases use a single increasing release number. Releases are automatically published every git push after CI testing.

Name

purple in Welsh is porffor. Why purple?

• No other JS engine is purple colored
• Purple is pretty cool
• Purple apparently represents "ambition", which accurately describes this project :)
