Sign Recurly.js forms from nodejs!

We looked high and low for a nodejs library to sign Recurly.js forms. After some solid google action, we even asked our #seedcamp compadres and fellow Recurlyists http://github.com/SocialBro and our nodejs neighbours http://github.com/gosquared, and we concluded that it didn't yet exist. So we wrote one.

Installation

Include in package.json

This is the safest way to link to github instead for modules, and npm knows what to do with tarballs

...
dependencies {
  "node-recurlyjs-sign": "https://github.com/brandid/node-recurlyjs-sign/tarball/master"
}

Use the same config file from the node-recurly module

Everyone using this probably already uses the node-recurly module, so we made it easy to have both installed.

Just make sure you have PRIVATE_KEY in your config

module.exports = {
  ...
  PRIVATE_KEY:  '<your private key, do not share this EVER>',
  ...
};

For those of you that are looking for a fork of the original node-recurly module that actually works, look no further than: http://github.com/socialbro/node-recurly

Usage

Require it

var recurlyjs = require("node-recurlyjs-sign");

then when you want to use it

Use different configs depending on environment

if(process.env.NODE_ENV === "production") {
  var recurlyKeys = require('./recurly-prod-config');
else {
  var recurlyKeys = require('./recurly-dev-config');
}

Generate signature

var signature = recurlyjs.sign(params, recurlyKeys.PRIVATE_KEY);

Params recursively get parsed into a signable object

You know that feeling when you just wrote a recursive function and you want to tell everyone about it? This is that.

All you have to do is pass the required parameter object as stated in the Recurly.js docs, and the module will automatically flatten it into the proper signable object

one-off transaction example - required params

var params = {
  "transaction": {
    "amount_in_cents":1999,
    "currency":"GBP"
  }
}
