About P1PP

P1PP is a simple-to-use javascript client for connecting to an XMPP pubsub service. It will use WebSockets if possible or degrade to BOSH.

Building

In the Makefile, if you want to use minification, set GOOGLE_CC and JAVA variables to correct locations

Then typing make will generate P1PP.js file and make minified minified version of that file: P1PP.js.min

Usage

P1PP.connect()

This function connects to server and allows you to pass configuration parameters used by other functions.

Example:

P1PP.connect({
  jid: 'myaccount@test.server.com',
  password: '*****',
  domain: 'test.server.com',
  nodes: ['my-test-node'],
  debug: true
})

You can pass those parameters to alter library configuration:

• jid - JID of account to used (optional). If none is passed anonymous connection will be performed.

• password - password for used account (optional). This field is only required when jid is passed as well.

• ws_url - Url to websocket service. Default value is "ws://p1pp.net:5280/xmpp"

• bosh_url - Url to http-bind service. Default value is "ws://p1pp.net:5280/http-bind"

• domain - Domain used by xmpp server. Default value is "p1pp.net"

• rebind - When set to true, reconnecting to server after page reload will try to use fast rebind method

• flash_location - Path to place where flash helper script is available, defaults to "WebSocketMain.swf"

• nodes - List of nodes to subscribe to

• connect_delay - Wait this much milliseconds before starting connecting to server. Default value is 0

• connect_retry - How much times reconnection should be tried before failing completely

• connect_timeout - Time in milliseconds before reconnections

• debug - If set to true, debug messages will be delivered using console.info interface

• publish - Callback function called when a new value is published in any of subscribed node. This function should have a signature similar to function(id, value, node, timestamp),

  • id - identifier of received value, identical value will be used if that value will be retracted
  • value - published value content, DOM element
  • node - name of node in which that value was published
  • timestamp - string with date when node was published, may be null

• retract - Callback called when value was deleted from one of subscribed node, this callback should be function with this signature function(id, node), id is a string identifying retracted value, and node is a node name where retracted value was stored

• on_strophe_event - Callback called when underlying strophe connection state is changed, it's called with one of Strophe.Status.* values as argument.

P1PP.disconnect()

Closes connection to server

Example:

P1PP.disconnect()

P1PP.subscribeToNode()

Subscribes to new node or nodes

Example:

P1PP.subscribeToNode(['timer@test.server.com/timer1', 'timer@test.server.com/timer2'])

This function takes list of strings with nodes, of single string with node as its argument

P1PP.unsubscribeFromNode()

Stop subscribing to changes performed in node or nodes

Example:

P1PP.unsubscribeFromNode(['timer@test.server.com/timer1', 'timer@test.server.com/timer2'])

This function takes list of strings with nodes, of single string with node as its argument

P1PP.publish()

Publish new data in node

Example:

P1PP.publish('timer', timer_event_id, timer_event_value, my_publish_callback)

This function takes 3 or 4 arguments, as first argument string with name of node should be passed. Second argument is used as identifier of value to send, when null is used, random name is generated. Third argument should be DOM element with stored value. Fourth should be callback, it's called when server request store operation finished, it's called with two arguments, identifier of stored value, and success (value "ok") or error code as second parameter.

This function returns identifier used to store value, it's equal to second value passed to this function, or generated value if null was passed to function.

P1PP.deleteNode()

Deletes node from server

Example:

P1PP.deleteNode('geolocation@test.server.com/locations', my_delete_callback)

Takes string with name of node to delete, and optional callback function called when operation finishes. Callback is called with "ok" when operation was completed successfully, or string with error code otherwise.

Access to underlying strophe connection

It's possible to get access to Strophe.Connection object used internally by P1PP. That object is available as P1PP.push_client.connection and only when connection was established, which may be determined by listening to events delivered through on_strophe_event callback.
