cfrelay

A relay run at cloudflare.

Features

Implement

Function	Cloudflare implement
Event Store	D1
File Store (NIP-95)	KV
File Store (NIP-96)	R2

Why do we use the KV to save the file store?

Because the R2 must bing the payment method and when it run out of the free plan limit, it would make some fee.

5.Init R2 (Optional)

If you want to use R2, you must config your payment to cloudflare. I can't ensure that it won't cost you money

After config payment, you can init the R2 bucket now. You can do it in the cloudflare website or run this script:

wrangler r2 bucket create relay

It is important that config a custom domain for your bucket. Due to this domain can user cloudflare's cache and it will save you money.
