Bring Shopping Lists API

An unofficial python package to access the Bring! shopping lists API.

This is a minimal python port of the node-bring-api by foxriver76. All credit goes to him for making this awesome API possible!

Installation

pip install python-bring-api

Documentation

See below for usage examples. See Exceptions for API-specific exceptions and mitigation strategies for common exceptions.

Usage Example

The API is available both sync and async, where sync is the default for simplicity. Both implementations of each function use the same async HTTP library aiohttp in the back.

Sync

import logging
import sys

from python_bring_api.bring import Bring

logging.basicConfig(stream=sys.stdout, level=logging.DEBUG)

# Create Bring instance with email and password
bring = Bring("MAIL", "PASSWORD")
# Login
bring.login()

# Get information about all available shopping lists
lists = bring.loadLists()["lists"]

# Save an item with specifications to a certain shopping list
bring.saveItem(lists[0]['listUuid'], 'Milk', 'low fat')

# Save another item
bring.saveItem(lists[0]['listUuid'], 'Carrots')

# Get all the items of a list
items = bring.getItems(lists[0]['listUuid'])
print(items)

# Check off an item
bring.completeItem(lists[0]['listUuid'], 'Carrots')

# Remove an item from a list
bring.removeItem(lists[0]['listUuid'], 'Milk')

Async

import aiohttp
import asyncio
import logging
import sys

from python_bring_api.bring import Bring

logging.basicConfig(stream=sys.stdout, level=logging.DEBUG)

async def main():
  async with aiohttp.ClientSession() as session:
    # Create Bring instance with email and password
    bring = Bring("MAIL", "PASSWORD", sessionAsync=session)
    # Login
    await bring.loginAsync()

    # Get information about all available shopping lists
    lists = (await bring.loadListsAsync())["lists"]

    # Save an item with specifications to a certain shopping list
    await bring.saveItemAsync(lists[0]['listUuid'], 'Milk', 'low fat')

    # Save another item
    await bring.saveItemAsync(lists[0]['listUuid'], 'Carrots')

    # Get all the items of a list
    items = await bring.getItemsAsync(lists[0]['listUuid'])
    print(items)

    # Check off an item
    await bring.completeItemAsync(lists[0]['listUuid'], 'Carrots')

    # Remove an item from a list
    await bring.removeItemAsync(lists[0]['listUuid'], 'Milk')

asyncio.run(main())

Exceptions

In case something goes wrong during a request, several exceptions can be thrown. They will either be BringRequestException, BringParseException, or BringAuthException, depending on the context. All inherit from BringException.

Another asyncio event loop is already running

Because even the sync methods use async calls under the hood, you might encounter an error that another asyncio event loop is already running on the same thread. This is expected behavior according to the asyncio.run() documentation. You cannot call the sync methods when another event loop is already running. When you are already inside an async function, you should use the async methods instead.

Exception ignored: RuntimeError: Event loop is closed

Due to a known issue in some versions of aiohttp when using Windows, you might encounter a similar error to this:

Exception ignored in: <function _ProactorBasePipeTransport.__del__ at 0x00000000>
Traceback (most recent call last):
  File "C:\...\py38\lib\asyncio\proactor_events.py", line 116, in __del__
    self.close()
  File "C:\...\py38\lib\asyncio\proactor_events.py", line 108, in close
    self._loop.call_soon(self._call_connection_lost, None)
  File "C:\...\py38\lib\asyncio\base_events.py", line 719, in call_soon
    self._check_closed()
  File "C:\...\py38\lib\asyncio\base_events.py", line 508, in _check_closed
    raise RuntimeError('Event loop is closed')
RuntimeError: Event loop is closed

You can fix this according to this stackoverflow answer by adding the following line of code before executing the library:

asyncio.set_event_loop_policy(asyncio.WindowsSelectorEventLoopPolicy())
