This is a simple node script that makes it possible to interface directly with the cCurl Library via Node-FFI. What this is for is basically for doing Proof of Work without IRI Core. Hashing with cCurl is also arguably faster.
You can simply install this package with all its dependencies (iota.lib.js and ffi) via npm:
$ npm install ccurl.interface.js
After that, you will have to compile cCurl locally on your machine. Follow the instructions on the official repo here.
$ git clone https://github.com/iotaledger/ccurl.git
$ mkdir build && cd build && cmake .. && cd .. && make -C build
Then copy the libccurl library from the build/lib folder to the main directory.
Using this library is fairly simple. You can optionally provide the full path where you have your compiled libccurl.
var ccurl = import('ccurl.interface.js');
ccurl(trunkTransaction, branchTransaction, trytes, minWeightMagnitude, [, path], callback)
