PathfinderPC Server Interface

PathfinderPC Interface for Node.js

This package allows you to interact with PathfinderPC Server.

It keeps an in-memory database (nedb) to keep track of the state - so don't feel bad about querying it lots, it won't hit Pathfinder.

Installation

Do this to get it into your node project:

npm install pfint --save

Usage

Require it, create a new one.

var PFInterface = require('pfint')
var pfint = new PFInterface();
pfint.sync({
	'user' : "Pathfinder_User",
	'password' : "Pathfinder_Password",
	'host' : "localhost",
	'port' : 9500
})

PFInt gives off lots of events and things. It can also be queried.

Methods

There are a coupe of methods you can use

sync(options)

This is the method which starts up the connection.

{
	'user' : "Pathfinder_User",
	'password' : "Pathfinder_Password",
	'host' : "localhost",
	'port' : 9500
}

find(query, cb)

This is basically a passthrough for nedb.find.

cb(err, item)

There are various itemTypes that can be queried for.

• source
• destination
• router
• protocoltranslator
• routes

A bit like this:

pfint.find({'itemType' : 'protocoltranslator'}, function(err, pts)
{
    response.end(JSON.stringify(pts))		
})

findOne(query, cb)

The same as the above, except only one result gets returned.

Events

You can connect to events in the normal way:

pfint.on('debug', function (message) {
    console.log(message)
})

debug (message)

Debugging notes come out at various useful points.

connected

Is raised when we are connected to PathfinderPC

memorySlot (slot)

Is raised when a memory slot is updated

route (route)

Is raised when a route is created

error (message)

Raised when an error occurs (no, really?)

gpi (state) DRAFT

Raised when a GPI state changes
