v8.11.0 UnhandledSchemeError when bundling with Webpack

[andrew-pledge-io]

This line introduced in this PR is causing errors in Webpack builds.

Webpack compilation failed:
in cloudflare:sockets
  Module build failed: UnhandledSchemeError: Reading from "cloudflare:sockets" is not handled by plugins (Unhandled scheme).
  Webpack supports "data:" and "file:" URIs by default.
  You may need an additional plugin to handle "cloudflare:" URIs.

This occurred after a minor update to the pg package from v8.10.0 to v8.11.0 when the pg-cloudflare package was added as an optional dependency.

For now, we've reverted to v8.10.0.

I expect this will affect a lot of people using Webpack as they start to update.

@andrew-pledge-io — which version of Webpack are you using, where you hit this error?

I think this relates back to webpack/webpack#15741 — and declaring cloudflare:sockets as an external in Webpack may help?

[petebacondarwin]

Here is a minimal webpack setup that should work with the latest version:

const path = require("path");
const webpack = require("webpack");

module.exports = {
  entry: "./src/index.js",
  output: {
    filename: "main.js",
    path: path.resolve(__dirname, "dist"),
  },
  target: "node",
  mode: "development",
  plugins: [
    new webpack.IgnorePlugin({
      resourceRegExp: /^pg-native$|^cloudflare:sockets$/,
    }),
  ],
};

Note that we are ignoring both the pg-native and cloudflare:sockets imports since they are not needed here.

I put together a PR that I think should make this just work "out of the box" for everyday users of pg. See #2978.

This also fails for me when using Kysely together with NextJS, had to revert to 8.10 as well.
