node-etp v1.0.4-40

#Node ETP

This is a javascript serialization implementation for the Energistics Transfer protocol (ETP).

ETP is a proposed specification for streaming real-time data from oil field drilling and production facilities. It uses websockets for transport and Apache Avro for serialization. This node package contains:

1. A set of routines for serializing and deserialing binary Avro messages in javascript.
2. An array of the all of the ETP protocol message schemas in javascript form (i.e. a parsed version of the JSON message schemas) which can be passed to the Avro serializer to parse an incoming message.

#Prerequisites

• Install Node from nodejs.org - v0.10 min required.

#Installation

To install from npm

npm install node-etp

To install from source

Clone the node folder from bitbucket.

c:\energistics\src\node-etp git clone https://bitbucket.org/energistics/node-etp.git

Install into your project directory c:\ralfdemo>npm install c:\energistics\src\node-etp

#Using the library.

Create test.js

var avro = require("node-etp").Avro;
var schemas = require("node-etp").Schemas;

console.dir(schemas);

Run the file under node

c:\ralfdemo>node test
