Convert a Multiaddr to a URI

About

This module allows easy conversion of Multiaddrs to string URIs.

Example - Converting multiaddrs to string URIs

import { multiaddrToUri } from '@multiformats/multiaddr-to-uri'

console.log(multiaddrToUri('/dnsaddr/protocol.ai/https'))
// -> https://protocol.ai

console.log(multiaddrToUri('/ip4/127.0.0.1/tcp/8080'))
// -> http://127.0.0.1:8080

console.log(multiaddrToUri('/ip4/127.0.0.1/tcp/8080', { assumeHttp: false }))
// -> tcp://127.0.0.1:8080

Note:

  • When /tcp is the last (terminating) protocol HTTP is assumed by default (implicit assumeHttp: true)
    • this means produced URIs will start with http:// instead of tcp://
    • passing { assumeHttp: false } disables this behavior
  • Might be lossy - e.g. a DNSv6 multiaddr
  • Can throw if the passed multiaddr:
    • is not a valid multiaddr
    • is not supported as a URI e.g. circuit

Install

$ npm i @multiformats/multiaddr-to-uri
