bzz-proxy-poc

This repo is now archived as we have implemented this functionality as part of https://github.com/ethersphere/gateway-proxy/

Proof-of-concept proxy service for serving web content from Swarm with subdomains.

Usage

Installation

npm install

Running

npm start

Setting up DNS

You may need to set up DNS with wildcard submdomain support.

Environment variables

• PROXY_TARGET: the target host (default: http://localhost:1633)
• PROXY_PORT: the port to serve requests (default: 8633)

Utilities

Because the maximum length of a subdomain can be 63 characters, we need to convert Swarm hashes to CIDs.

There are command line utilities to convert a hash to CID:

% node hash2cid.js 3bde66cca4bcbc3c49f21b55446dc437fb2d71a1948528d181e743050a51e66d
{
  cid: 'bafybwib33ztmzjf4xq6et4q3kvcg3rbx7mwxdimuquundaphimcquupgnu',
  version: 1,
  codec: 'dag-pb',
  multihash: Uint8Array(34) [
     27,  32,  59, 222, 102, 204, 164, 188,
    188,  60,  73, 242,  27,  85,  68, 109,
    196,  55, 251,  45, 113, 161, 148, 133,
     40, 209, 129, 231,  67,   5,  10,  81,
    230, 109
  ],
  multibaseName: 'base32'
}

And CID to hash:

% node cid2hash.js bafybwib33ztmzjf4xq6et4q3kvcg3rbx7mwxdimuquundaphimcquupgnu
