@multiformats/multiaddr-matcher

Match different multiaddr formats

About

This module exports various matchers that can be used to infer the type of a passed multiaddr.

Example

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

Example

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

Install

$ npm i @multiformats/multiaddr-matcher
