Get an IPFS resource

import sys
import asyncio

import aioipfs

async def get(ipfshash):
    client = aioipfs.AsyncIPFS()
    await client.get(ipfshash, dstdir='.')
    await client.close()

loop = asyncio.get_event_loop()
loop.run_until_complete(get(sys.argv[1]))
loop.close()

Add some files

This example will import all files and directories specified on the command line. Note that the add API function is an asynchronous generator and therefore needs to be used with the async for syntax.

import sys
import asyncio

import aioipfs

async def add_files(files):
    client = aioipfs.AsyncIPFS()

    async for added_file in client.add(*files, recursive=True):
        print('Imported file {0}, CID: {1}'.format(
            added_file['Name'], added_file['Hash']))

    await client.close()

loop = asyncio.get_event_loop()
loop.run_until_complete(add_files(sys.argv[1:]))
loop.close()

Pubsub service

async def pubsub_serve(topic):
    async with aioipfs.AsyncIPFS() as cli:
        async for message in cli.pubsub.sub(topic):
            print('Received message from', message['from'])
            await cli.pubsub.pub(topic, message['data'])

Async file writing on get operations

The aiofiles library is used to asynchronously write data retrieved from the IPFS daemon when using the /api/v0/get API call, to avoid blocking the event loop. TAR extraction is done in asyncio’s threadpool.
