Can you reference the Eleventy configuration file as data?

Say, for example, I want to set the global site.url to url: process.env.URL || "http://localhost" + eleventyConfig.setServerOptions.port (that line would be within _data/site.js).

Possibly:

// src/_data/site.js
const DEFAULT_PORT = process.env.PORT || (process.env.URL && new URL(process.env.URL).port) || 8000;

module.exports = {
  url: process.env.URL || `http://localhost:${DEFAULT_PORT}`,
  port: DEFAULT_PORT,
};

// .eleventy.js
const { port } = require("./src/_data/site");

/**
 * @typedef {import('@11ty/eleventy/src/UserConfig')} EleventyConfig
 * @typedef {ReturnType<import('@11ty/eleventy/src/defaultConfig')>} EleventyReturnValue
 * @type {(eleventyConfig: EleventyConfig) => EleventyReturnValue}
 */
module.exports = function (eleventyConfig) {
  eleventyConfig.setServerOptions({ port });
  console.log(eleventyConfig.serverOptions);

  return {
    dir: {
      input: "src",
      output: "www",
    },
  };
};

Thank you! Worked like a charm.
