+# 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](https://github.com/wintercg/proposal-sockets-api) proposed within WinterCG, and implemented in [Cloudflare Workers](https://developers.cloudflare.com/workers/runtime-apis/tcp-sockets/), 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
+```
+
+The package uses conditional exports to support bundlers that don't know about
+`cloudflare:sockets`, so the consumer code by default imports an empty file. To
+enable the package, resolve to the `cloudflare` condition in your bundler's
+config. For example:
+
+- `webpack.config.js`
+  ```js
+  export default {
+    ...,
+    resolve: { conditionNames: [..., "workerd"] },
+    plugins: [
+      // ignore cloudflare:sockets imports
+      new webpack.IgnorePlugin({
+        resourceRegExp: /^cloudflare:sockets$/,
+      }),
+    ],
+  }
+  ```
+- `vite.config.js`
+
+  > [!NOTE]
+  > If you are using the [Cloudflare Vite plugin](https://www.npmjs.com/package/@cloudflare/vite-plugin) then the following configuration is not necessary.
+
+  ```js
+  export default defineConfig({
+    ...,
+    resolve: {
+      conditions: [..., "workerd"],
+    },
+    build: {
+      ...,
+      // don't try to bundle cloudflare:sockets
+      rollupOptions: {
+        external: [..., 'cloudflare:sockets'],
+      },
+    },
+  })
+  ```
+
+- `rollup.config.js`
+  ```js
+  export default defineConfig({
+    ...,
+    plugins: [..., nodeResolve({ exportConditions: [..., 'workerd'] })],
+    // don't try to bundle cloudflare:sockets
+    external: [..., 'cloudflare:sockets'],
+  })
+  ```
+- `esbuild.config.js`
+  ```js
+  await esbuild.build({
+    ...,
+    conditions: [..., 'workerd'],
+  })
+  ```
+
+The concrete examples can be found in `packages/pg-bundler-test`.
+
+## How to use conditionally, in non-Node.js environments
+
+As implemented in `pg` [here](https://github.com/brianc/node-postgres/commit/07553428e9c0eacf761a5d4541a3300ff7859578#diff-34588ad868ebcb232660aba7ee6a99d1e02f4bc93f73497d2688c3f074e60533R5-R13), 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:
+
+```js
+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 available in a Node.js environment, [`@arrowood.dev/socket`](https://github.com/Ethan-Arrowood/socket) provides a Node.js implementation of the Socket API.
