PyBeamIt

This is a python wrapper around the unofficial just beam it API. It supports both sending and receiving files.

Usage

Integrating P2P file sharing capability in your application is extremely simple.

First, install requirements with

pip install -r requirements.txt

Then on the sender's machine:

from pybeamit import JustBeamIt

j = JustBeamIt("file.wav")
#or for multiple files:
j = JustBeamIt(("file.wav", "file2.mp3"))
t=j.tokenise()
print("retrieval url for recipient: "+t)
print("waiting for recipient...")
j.wait()
print("starting the transfer")
j.transfer()
print("done")

On the receiving end:

from pybeamit import JustBeamIt

url = ""  # e.g. https://www.justbeamit.com/s8x9j
j = JustBeamIt()
j.download(url, path="dest")

There are also a couple demos.

All operations require a JustBeamIt object:

class JustBeamIt(files=[], base_url=None, backend_url=None)

Once you have an instance, the following methods are defined:

tokenise()
	Initiates the transfer with a backend server, returning a URL for download.
	note: This must be called on the sender's machine.

wait()
	Blocks until a recipient is available to receive the file.

transfer(progress_callback=None)
	Perform the transfer, blocking until complete.
	progress_callback will be called internally with one parameter, percentage
	note: As of version 0.3, wait must be called first to ensure the other peer is ready to receive the file.

download(self, url_or_token, path=None, progress_callback=None, chunk_size=1024)
	Blocking function that initiates a download.
	The downloaded file will be saved in path (if provided) otherwise the current directory.
	progress_callback will be called internally with one parameter, the percentage of the transfer (0-100).
