the powr project

Development is paused until 2023. 🥳

powr aims to be a javascript/typescript engine to power serverless functions over the web. the javascript code gets compiled to remove as much cold start interpreting would cause as possible.

the project currently doesn't support anything other than calling console.log with a string argument. if you want to test that, you can run the following:

$ git clone https://github.com/pwrjs/pwr --recursive
$ cd pwr/samples
$ cargo run --release c hello_world.ts
$ ./hello_world

I recommend adding --jobs [number of jobs] to the cargo run command to speed up compilation.

usage

section of the output of powr --help:

Usage:
	powr [OPTIONS] [FILE]

Flags:
	-h, --help : Show help

Commands:
	c, compile : Compile a TypeScript/JavaScript file

and powr compile --help:

Description:
	Compile a TypeScript/JavaScript file

Usage:
	powr compile [FILE] [OPTIONS]

Flags:
	-e, --emmit-llvm  : Emmit LLVM IR
	-d, --dry-run     : Only emits the LLVM IR
	-h, --help        : Show help

--emit--llvm leaves an .ll file that corresponds to the .ts file.

--dry-run outputs what would be emitted to the .ll file and exits.

license

currently, the project uses SSPL-1.0. this license will be changed when the project gets to a more usable state. because this license blocks lesser effort (for a lack of a better term!) contributions (and these are very desirable!), the license may become more permissive before the project is shippable.
