Landing page not loading when using Wrangler 2 instead of miniflare

[y0hami]

If using wrangler 2 dev environment (built on top of miniflare) instead of miniflare like the starter template the landing page doesn't load due to this line https://github.com/mrbbot/slshx/blob/master/src/index.ts#L43 looking for the MINIFLARE global which doesn't exist.

Current work around is to set it before handling the fetch.

(globalThis as any).MINIFLARE = true

Possible fix could be to check for the environment which is explained on this page https://developers.cloudflare.com/workers/platform/environments/
