lastfm-proxy

A Cloudflare Worker acting as a proxy for the LastFM API in order to expose endpoints.

The dev and prod versions I built this for are deployed to the following, targeting my last.fm user account, BrianMitchL.

Environment	URL
Dev	https://lastfm-proxy-dev.brianm.me
Prod	https://lastfm-proxy.brianm.me

Use

There are two routes, /tracks and /artists, each can be supplied with the optional period search parameter with one of the following options: overall | 7day | 1month | 3month | 6month | 12month. If none is specified, we default to overall.

Example: https://lastfm-proxy-dev.brianm.me/tracks?period=7day

Getting Started

This worker is meant to be used with Wrangler. Documentation can be found here.

Developing

src/index.js calls the request handler in src/handler.ts, and will return the request method for the given request.

Configuration

There are two environment variables used to configure the worker.

Variable	Use
LASTFM_USERNAME	The LastFM username to source the data from.
LASTFM_API_KEY	The LastFM API key used to authorize the request. This is configured as a secret variable in Cloudflare/Wrangler.

Testing

npm run test will run the tests.

Previewing and Publishing

Run npm run start to run a test version of the worker.

Run wrangler publish --env=dev or wrangler publish to publish the dev or prod versions. The GitHub Actions should do this automatically when merging into the dev or main branches.
