aiofirebase

asyncio (PEP 3156) Firebase client library.

Install

aiofirebase requires Python 3.5 or above.

$ pip install aiofirebase

Usage

Setup

Begin by importing aiofirebase:

>>> import aiofirebase

And create a client that we will use to interact with firebase:

>>> firebase = aiofirebase.FirebaseHTTP("https://<YOUR-FIREBASE-APP>.firebaseio.com/")

Retrieving data

We can now read data from our database:

>>> await firebase.get(path='dinosaurs')
"dinosaurs": {
  "lambeosaurus": {
    "height": 2.1,
    "length": 12.5,
    "weight": 5000
  }
}

Saving data

We can also create new data in the database:

>>> await firebase.put(path='dinosaurs', value={'stegosaurus': {'height': 4, 'length': 9, 'weight': 2500}})
{
  'stegosaurus': {
    "height": 4,
    "length": 9,
    "weight: 2500
  }
}

Update data

We can also update specific children at a location without overwriting existing data:

>>> await firebase.patch(path='dinosaurs/stegosaurus', value={'width': 2})
{
  "width": 2
}

Note: If we had done a create instead of a update, the data we added in the create would of been overwritten.

We can also update values at multiple locations in your Firebase database at the same time:

>>> await firebase.patch(path='dinosaurs', value={'lambeosaurus/width': 1, 'stegosaurus/width': 2})

Saving lists of data

If you need to save lists of data, each item should be saved against a unique key. Firebase will generate this unique key and save the child by making a POST request.

>>> await firebase.post(path='posts', value={'author': 'alanisawesome', 'title': 'The Turing Machine'})

Removing data

Data can also be removed by making a DELETE request:

>>> await firebase.delete('dinosaurs/stegosaurus')

Watch for updates

Firebase provides a way to receive events when data changes in your database via the EventSource protocol.

aiofirebase can listen for these events, and send each event received to a callback of your choice.

>>> async def mycallback(event, data):
...     print('{} event received.'.format(event))
...
>>> await firebase.stream(callback=mycallback, path='dinosaurs')
