Last.fm Mixmax link resolver

This will expand last.fm urls to a short preview.


Running locally

1. Install using npm install
2. Add your lastfm API key to utils/key.js
3. Run using npm start To simulate locally how Mixmax calls the resolver URL (to return HTML that goes into the email), run:

curl https://localhost:9146/resolver?url=http%3A%2F%2Flast.fm%2Fuser%2F14nicholasse --insecure

Why do we run it in https locally?

Mixmax slash command APIs are required to be served over https. This is because they are queried directly from the Mixmax client in the browser (using AJAX) that's running on an HTTPS domain. Browsers forbid AJAX requests from https domains to call http APIs, for security. So we must run an https server with a locally-signed certificate.

See here for how to fix the ERR_INSECURE_RESPONSE error that you might get in Chrome.

Installing to Mixmax

Add the resolver to the dashboard: https://app.mixmax.com/dashboard/settings/integrations Use last.fm/user/[^\/]+$ for the regex and https://localhost:9146/resolver for resolver url
