multiaddr implementation (binary + string representation of network addresses)
JavaScript implementation of multiaddr.
A standard way to represent addresses that
npm i multiaddr
const multiaddr = require('multiaddr')
The code published to npm that gets loaded on require is in fact a ES5 transpiled version with the right shims added. This means that you can require it and use with your favourite bundler without having to adjust asset management process.
const multiaddr = require('multiaddr')
<script> TagLoading this module through a script tag will make the Multiaddr obj available in
the global namespace.
<script src="https://unpkg.com/multiaddr/dist/index.min.js"></script>
$ node
> const multiaddr = require('multiaddr')
> 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:
const multiaddr = require('multiaddr')
const resolvers = require('multiaddr/src/resolvers')
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>>.
