simperium-python

Simperium is a simple way for developers to move data as it changes, instantly and automatically. This is the Python library. You can browse the documentation.

You can sign up for a hosted version of Simperium. There are Simperium libraries for other languages too.

This is not yet a full Simperium library for parsing diffs and changes. It's a wrapper for our HTTP API intended for scripting and basic backend development.

Getting Started

To get started, first log into https://simperium.com and create a new application. Copy down the new app's name, api key and admin key.

Next install the python client:

$ sudo pip install git+https://github.com/Simperium/simperium-python.git

Start python and import the lib:

$ python
>>> from simperium.core import Auth, Api

We'll need to create a user to be able to store data:

>>> auth = Auth(yourappname, yourapikey)
>>> token = auth.create('[email protected]', 'secret')
>>> token
'25c11ad089dd4c18b84f24bc18c58fe2'

We can now store and retrieve data from simperium. Data is stored in buckets. For example, we could store a list of todo items in a todo bucket. When you store items, you need to give them a unique identifier. Uuids are usually a good choice.

>>> import uuid
>>> api = Api(yourappname, token)
>>> todo1_id = uuid.uuid4().hex
>>> api.todo.post(todo1_id,
                  {'text': 'Read general theory of love', 'done': False})

We can retrieve this item:

>>> api.todo.get(todo1_id)
{'text': 'Read general theory of love', 'done': False}

Store another todo:

>>> api.todo.post(uuid.uuid4().hex,
                  {'text': 'Watch battle royale', 'done': False})

You can retrieve an index of all of a buckets items:

>>> api.todo.index()
{
    'count': 2,
    'index': [
        {'id': 'f6b680f8504c4e31a0e54a95401ffca0', 'v': 1},
        {'id': 'c0d07bb7c46e48e693653425eca93af9', 'v': 1}],
    'current': '4f8507b8faf44720dfc432b1',}

Retrieve all the docuemnts in the index:

>>> [api.todo.get(x['id']) for x in api.todo.index()['index']]
[
    {'text': 'Read general theory of love', 'done': False},
    {'text': 'Watch battle royale', 'done': False}]

It's also possible to get the data for each document in the index with data=True:

>>> api.todo.index(data=True)
{
    'count': 2,
    'index': [
        {'id': 'f6b680f8504c4e31a0e54a95401ffca0', 'v': 1,
            'd': {'text': 'Read general theory of love', 'done': False},},
        {'id': 'c0d07bb7c46e48e693653425eca93af9', 'v': 1,
            'd': {'text': 'Watch battle royale', 'done': False},}],
    'current': '4f8507b8faf44720dfc432b1'}

To update fields in an item, post the updated fields. They'll be merged with the current document:

>>> api.todo.post(todo1_id, {'done': True})
>>> api.todo.get(todo1_id)
{'text': 'Read general theory of love', 'done': True}

Simperium items are versioned. It's possible to go back in time and retrieve previous versions of documents:

>>> api.todo.get(todo1_id, version=1)
{'text': 'Read general theory of love', 'done': False}

Of course, you can delete items:

>>> api.todo.delete(todo1_id)
>>> api.todo.get(todo1_id) == None
True
>>> api.todo.index()['count']
