Install

$ npm i @multiformats/multiaddr-to-uri

Browser <script> tag

Loading this module through a script tag will make it's exports available as MultiformatsMultiaddrToUri in the global namespace.

<script src="https://unpkg.com/@multiformats/multiaddr-to-uri/dist/index.min.js"></script>

Usage

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
