SylvaDB API - Python Client

The SylvaDB API client allows the interaction with the SylvaDB API in an easily and flexible way.

Installation

$ pip install sylvadbclient

Getting started

To start, we need to instance the main class called API. It takes two parameters, the host where our api is running and the authorization to establish the connection. Optionally, a third parameter graph_slug can be passed to the API knows which graph to use by default:

>>> from sylvadbclient import API

>>> api = API(auth=("default", "default"))

>>> api = API(auth=("default", "default"), graph_slug="graph-1")

Right now, we can interact with the api using the available methods (see the docs). All the responses that we obtain are in JSON format:

# We get all the graphs for user "default"
>>> api.get_graphs()

# We get the graph called "test"
>>> api.get_graph("test")

# We get the graph called "test"
>>> api.get_graph("test")

# We get the graph node types
>>> api.get_nodetypes("test")

However, SylvaDB client provides a higher level API, the Graph:

>>> from sylvadbclient import Graph

>>> g = Graph(graph_slug="graph-1")

>>> g.name
'Country'

Almost every object can be retrieved from server by invoking the medthod .pull(), and any change can be saved by using .push(). In the event of running a .pull() before a .push(), all local changes are lost.

>>> g.description = "Network"

>>> g.push()

Both nodes and relationships can be listed according to their schema type:

>>> g.nodes.types.all()
[{'description': None, 'name': 'Country', 'schema': 4, 'slug': 'country-2'},
 {'description': None, 'name': 'Software', 'schema': 4, 'slug': 'software-2'},
 {'description': None,
  'name': 'Traditional',
  'schema': 4,
  'slug': 'traditional-2'}]

>>> country_type = g.nodes.types.single()

>>> countries = g.nodes[country_type]
>>> countries
<SylvaDB NodeDataCollection of country-2 at 0x7f3620f3ea90>

>>> countries[2:4]
[{'id': 120, 'properties': {'Name': 'Austria'}},
 {'id': 130, 'properties': {'Name': 'United States'}}]

>>> countries.all()
...

And adding new nodes or relationships is as easy as adding a new dictionary to a type:

>>> countries.add({'Name': 'United States'})

>>> countries[-1]
{'id': None, 'properties': {'Name': 'United States'}}

>>> countries.push()

>>> countries[-1]
{'id': 180, 'properties': {'Name': 'United States'}}
