Advanced tools
Node.js implementation of the TCP module that libp2p uses, which implements the interface-connection and interface-transport interfaces
JavaScript implementation of the TCP module for libp2p. It exposes the interface-transport for dial/listen.
libp2p-tcp
is a very thin shim that adds support for dialing to amultiaddr
. This small shim will enable libp2p to use other transports.
> npm install libp2p-tcp
const TCP = require('libp2p-tcp')
const multiaddr = require('multiaddr')
const pipe = require('it-pipe')
const { collect } = require('streaming-iterables')
// A simple upgrader that just returns the MultiaddrConnection
const upgrader = {
upgradeInbound: maConn => maConn,
upgradeOutbound: maConn => maConn
}
const tcp = new TCP({ upgrader })
const listener = tcp.createListener((socket) => {
console.log('new connection opened')
pipe(
['hello'],
socket
)
})
const addr = multiaddr('/ip4/127.0.0.1/tcp/9090')
await listener.listen(addr)
console.log('listening')
const socket = await tcp.dial(addr)
const values = await pipe(
socket,
collect
)
console.log(`Value: ${values.toString()}`)
// Close connection after reading
await listener.close()
Outputs:
listening
new connection opened
Value: hello
libp2p-tcp
accepts TCP addresses as both IPFS and non IPFS encapsulated addresses, i.e:
/ip4/127.0.0.1/tcp/4001
/ip4/127.0.0.1/tcp/4001/ipfs/QmHash
(both for dialing and listening)
Contributions are welcome! The libp2p implementation in JavaScript is a work in progress. As such, there's a few things you can do right now to help out:
