A standard way to represent addresses that
import { multiaddr } from 'multiaddr'
const addr = multiaddr("/ip4/127.0.0.1/udp/1234")
// Multiaddr(/ip4/127.0.0.1/udp/1234)
const addr = multiaddr("/ip4/127.0.0.1/udp/1234")
// Multiaddr(/ip4/127.0.0.1/udp/1234)
addr.bytes
// <Uint8Array 04 7f 00 00 01 11 04 d2>
addr.toString()
// '/ip4/127.0.0.1/udp/1234'
addr.protos()
/*
[
{code: 4, name: 'ip4', size: 32},
{code: 273, name: 'udp', size: 16}
]
*/
// gives you an object that is friendly with what Node.js core modules expect for addresses
addr.nodeAddress()
/*
{
family: 4,
port: 1234,
address: "127.0.0.1"
}
*/
addr.encapsulate('/sctp/5678')
// Multiaddr(/ip4/127.0.0.1/udp/1234/sctp/5678)
multiaddr allows multiaddrs to be resolved when appropriate resolvers are provided. This module already has resolvers available, but you can also create your own. Resolvers should always be set in the same module that is calling multiaddr.resolve() to avoid conflicts if multiple versions of multiaddr are in your dependency tree.
To provide multiaddr resolvers you can do:
import { resolvers } from 'multiaddr'
resolvers.set('dnsaddr', resolvers.dnsaddrResolver)
The available resolvers are:
| Name | type | Description |
|---|---|---|
dnsaddrResolver | dnsaddr | dnsaddr resolution with TXT Records |
A resolver receives a Multiaddr as a parameter and returns a Promise<Array<string>>.
