webfinger-client

A webfinger client that runs both in the browser and in node.js. The Client is based on Nick Jennings library webfinger.js but has been rewritten in TypeScript.

Demo

Check out the Demo at GitHub Pages: https://d-koppenhagen.github.io/webfinger/

Features

• defaults to TLS only
• optional URI fallback (for older services which use host-meta or host-meta.json URI endpoints)
• optional support for WebFist

Demo

clone this repository, run npm install and finally npm start

Install

Install the client as a dependency:

npm install --save webfinger-client

Usage

Import

You have to import the module before using it:

import { WebFinger } from 'webfinger';

Use

  let webfinger = new WebFinger({
    webfistFallback: true,  // defaults to false
    tlsOnly: true,          // defaults to true
    uriFallback: false,     // defaults to false
    requestTimeout: 10000,  // defaults to 10000
  });

  webfinger.lookup('[email protected]', function (err, p) {
    if (err) {
      console.log('error: ', err.message);
    } else {
      console.log(p);
    }
  });


// example output:
// {
//   idx: {
//     properties: {
//       name: "Alice Henderson"
//     },
//     links: {
//       avatar: [{ href: '<url>' }],
//       blog: [{ href: '<url>' }],
//       vcard: [href: '<url' }]
//       ... etc.
//     },
//   }
//   json: { ... raw json output ... }
//   object: { ... unformatted but parsed into native javascript object ... }
// }

  webfinger.lookupLink('[email protected]', 'remotestorage' function (err, p) {
    if (err) {
      console.log('error: ', err.message);
    } else {
      console.log(p);
    }
  });

// example output (if at least one link with rel="remotestorage" exists):
// {
//   href: 'https://storage.5apps.com/alice',
//   rel : 'remotestorage',
//   properties: {
//     'http://remotestorage.io/spec/version': 'draft-dejong-remotestorage-02',
//     'http://tools.ietf.org/html/rfc6749#section-4.2': 'https://5apps.com/rs/oauth/alice',
//     'http://tools.ietf.org/html/rfc6750#section-2.3': false,
//     'http://tools.ietf.org/html/rfc2616#section-14.16': false
//   }
// }
