A rapid RPC Framework for building p2p networks

# Installation

```

pip install synapse-p2p

```

# How does it work?

This example creates a public endpoints called `sum` which anyone on the network may call. There's also a background task `do_stuff` which is a task running in the background.

```python

from synapse_p2p.server import Server

app = Server()

@app.background(3)

async def do_stuff():

    print("Running background task every 3 seconds")

@app.endpoint("sum")

async def my_endpoint(a, b, response, **kwargs):

    response.write(f"The sum is {a + b}".encode())

app.run()

```

## Calling an endpoint on a node from a Python client

Synapse uses MsgPack-RPC, so we craft a payload and send it over TCP:

```python

import socket

from synapse_p2p.messages import RemoteProcedureCall

from synapse_p2p.serializers import MessagePackRPCSerializer

sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

sock.connect(("127.0.0.1", 9999))

sock.send(

    MessagePackRPCSerializer.serialize(RemoteProcedureCall(endpoint="sum", args=[1, 2]))

)

data = sock.recv(1024)

print(f"Received: \n{data.decode()}")

sock.close()

```

```
