pg-cloudflare

pg-cloudflare makes it easier to take an existing package that relies on tls and net, and make it work in environments where only connect() is supported, such as Cloudflare Workers.

pg-cloudflare wraps connect(), the TCP Socket API proposed within WinterCG, and implemented in Cloudflare Workers, and exposes an interface with methods similar to what the net and tls modules in Node.js expose. (ex: net.connect(path[, options][, callback])). This minimizes the number of changes needed in order to make an existing package work across JavaScript runtimes.

Installation

npm i --save-dev pg-cloudflare

How to use conditionally, in non-Node.js environments

As implemented in pg here, a typical use case might look as follows, where in a Node.js environment the net module is used, while in a non-Node.js environment, where net is unavailable, pg-cloudflare is used instead, providing an equivalent interface:

module.exports.getStream = function getStream(ssl = false) {
  const net = require('net')
  if (typeof net.Socket === 'function') {
    return net.Socket()
  }
  const { CloudflareSocket } = require('pg-cloudflare')
  return new CloudflareSocket(ssl);
}

Node.js implementation of the Socket API proposal

If you're looking for a way to rely on connect() as the interface you use to interact with raw sockets, but need this interface to be availble in a Node.js environment, @arrowood.dev/socket provides a Node.js implementation of the Socket API.
