Jabber Object Access Protocol XEP-0075 library for node-xmpp.
With package manager npm:
npm install node-xmpp-joap
xmpp = require "node-xmpp"
joap = require "node-xmpp-joap"
comp = new xmpp.Component
jid : "mycomponent"
password : "secret"
host : "127.0.0.1"
port : "8888"
class User
constructor: (@id, options={}) ->
# create a new manager instance
mgr = new joap.Manager comp
# add a class
mgr.addClass "User", User,
required: ["name", "age"]
protected: ["id"]
constructorAttributes: ["id", "options"]
# implement the ACL by overriding the method
mgr.hasPermission = (action, next) ->
if myACLRules(action) then next null, action
else next (new joap.Error "You are not allowed to do that :-P"), 403
If you want to persist the objects in a database you can simply override the
methods saveInstance
, loadInstance
and deleteInstance
.
In this example we use nStore.
nStore = require "nstore"
# create database
users = nStore.new './data/users.db', (err) ->
if err?
console.error err
else
# override
mgr.saveInstance = (action, obj, next) ->
if action.class is "User"
users.save obj.id, obj, (err) -> next err, action
else
next (new Error "Storage for this class is not available"), a
# override
mgr.loadInstance = (action, next) ->
if action.class is "User"
users.get id, (err, inst) -> next err, action, inst
else
next (new Error "Storage for this class is not available"), a
# override
mgr.queryInstances = (a, next) ->
if a.class is "User"
if a.attributess?
@users.find a.attributes, (err, res) -> next err, a, (id for id of res)
else
@users.all (err, res) -> next err, a, (id for id of res)
else
next (new Error "Storage for this class is not available"), a
# override
mgr.deleteInstance = (a, next) ->
if a.class is "User"
users.remove id, (err) -> next err, a
else
next (new Error "Storage for this class is not available"), a
