$ npm install @multiformats/multiaddr-matcher
Match different multiaddr formats
This module exports various matchers that can be used to infer the type of a passed multiaddr.
import { multiaddr } from '@multiformats/multiaddr'
import { DNS } from '@multiformats/multiaddr-matcher'
const ma = multiaddr('/dnsaddr/example.org')
DNS.matches(ma) // true - this is a multiaddr with a DNS address at the start
The default matching behaviour ignores any subsequent tuples in the multiaddr.
If you want stricter matching you can use .exactMatch
:
import { multiaddr } from '@multiformats/multiaddr'
import { DNS, Circuit } from '@multiformats/multiaddr-matcher'
const ma = multiaddr('/dnsaddr/example.org/p2p/QmFoo/p2p-circuit/p2p/QmBar')
DNS.exactMatch(ma) // false - this address has extra tuples after the DNS component
Circuit.matches(ma) // true
Circuit.exactMatch(ma) // true - the extra tuples are circuit relay related
$ npm i @multiformats/multiaddr-matcher
