Blockchain Receive

A super simple NodeJS module for interacting with Blockchain's Receive API. It depends on being run within the context of Express.

Documentation

setup

blockchain.setup(expressApp, baseURL)

This function only needs to be called once in order to set up the module. The first argument is your Express app instance, and the second is your application's publicly accessible URL.

onTransactionChange

blockchain.onTransactionChange(callback);

Add a handler for when the status of one of your Blockchain transactions changes.

offTransactionChange

blockchain.offTransactionChange(callback);

Remove a transaction handler

generateAddress

blockchain.generateAddress(recipientAddress, customParameters, callback);

Generate a new Bitcoin address which will forward all Bitcoins to the recipientAddress and alert you of any status changes.

Example

var express = require('express');
var blockchain = require('blockchain-receive');

var app = express();

blockchain.setup(app, 'http://example.com');

blockchain.onTransactionChange(function(info, done) {
  console.log(info);
  done(true);
});

blockchain.generateAddress('1FfmbHfnpaZjKFvyi1okTjJJusN455paPH', {
  customParam: 'somevalue123',
  secret: 'secretvalue'
}, function(address) {
  console.log(address);
});

app.listen(80);
