[DEP0111] DeprecationWarning: Access to process.binding('http_parser') is deprecated.

[dmnsgn]

Issue

process.binding() is for use by Node.js internal code only.

See: https://nodejs.org/api/deprecations.html#DEP0111

Fix

Use: _http_common

const { methods, HTTPParser } = require("_http_common");

Example implementation in undici:
https://github.com/nodejs/undici/pull/564/files

Test equality

const assert = require("assert");

const { methods: deprecatedMethods, HTTPParser: deprecatedHTTPParser } =
  process.binding("http_parser");
const { methods, HTTPParser } = require("_http_common");

assert.deepStrictEqual(methods, deprecatedMethods);
assert.strictEqual(methods, deprecatedMethods);

assert.strictEqual(
  HTTPParser.kOnHeadersComplete,
  deprecatedHTTPParser.kOnHeadersComplete
);
assert.strictEqual(
  HTTPParser.kOnMessageComplete,
  deprecatedHTTPParser.kOnMessageComplete
);
assert.strictEqual(HTTPParser.kOnBody, deprecatedHTTPParser.kOnBody);
