firebase-python-streaming

A nice, easy Python Firebase integration

Original Repo

https://github.com/shariq/firebase-python

Supports streaming data.

Requires requests and sseclient, which are on pip. If you don't know what that is, don't worry; just run ./setup.sh. Made for Python 2.7.

First create a Firebase here: https://www.firebase.com/signup/

(warning: The free level of Firebase only allows up to 50 concurrent connections. Don't hit this limit!)

Firebase object

Instaniate the object with using your firebase URL as follows:

firebase = Firebase('https://<YOUR_FIREBASE>.firebaseio.com/')

Code from the upstream repo supports different URL formats; this functionality is deprecated.

From here you can make get, put, and patch calls on the object. Additionally, you can navigate to child levels using child.

child

Use firebase.child("child") to navigate. This returns a reference to another firebase object with the URL of the child object.

firebase = Firebase('https://myfirebase.firebaseio.com/')
users = firebase.child("users")

andrew = users.child("andrewsosa001")

Since children objects are Firebase objects, you can use all the normal get/put/patch commands.

get and put

These commands have been object-oriented since the previous library. They are now called from the Firebase object, and do not require URLs to be provided.

get gets the value(s) of a Firebase it's given url, and put sets the value of a Firebase's url to some data.

>>> from firebase_streaming import Firebase

# Firebase object
>>> myFirebase = Firebase('https://myfirebase.firebaseio.com/')
>>> print myFirebase.get()  # this is an empty Firebase
None

>>> myFirebase.put('This is my firebase!')  # can take a string
>>> print firebase.get(URL)
This is my firebase!

>>> myFirebase.put({"Who's firebase?": "My firebase!"})  # or a dictionary
>>> print myFirebase.get(URL)
{"Who's firebase?": "My firebase!"}

# Sub-firebase.
>>> myColors = myFirebase.child("colors")
>>> print myColors.get()

>>> myColors.put({'color': 'red'})
>>> print myColors.get()
{'color': 'red'}

patch

patch adds new key value pairs to an existing Firebase, without deleting the old key value pairs.

>>> firebase = Firebase('https://myfirebase.firebaseio.com/')
>>> print firebase.get(URL)
None

>>> firebase.patch({'taste': 'tibetan'})
>>> print firebase.get()
{u'taste': u'tibetan'}

>>> firebase.patch({'size': 'tumbly})  # patching does not overwrite
>>> print firebase.get()
{u'taste': u'tibetan', u'size': u'tumbly'}

listener

The Firebase listener provides streaming functionality. It takes an optional callback function which it calls on every update to the Firebase object.

See sample.py for use. ``

URLs

This method has been deprecated in this library, and only exists to serve existing code from the previous version. Do not use these formats to instantiate your Firebase objects.

All URLs are internally converted to a Firebase URL format. This is done by the firebaseURL method. This method supports the following inputs.

>>> import firebase

>>> print firebase.firebaseURL('bony-badger')
https://bony-badger.firebaseio.com/.json

>>> print firebase.firebaseURL('bony-badger/bones/humerus')
https://bony-badger.firebaseio.com/bones/humerus.json

>>> print firebase.firebaseURL('bony-badger.firebaseio.com/')
https://bony-badger.firebaseio.com/.json

In this library version, the instantition name must end with .com/, as the .child() function appends the current Firebase's name with the child's directory. Because the name must end with /, the above formats are not supported by this library.
