This recipe ensures HTTP classes like OutgoingMessage, ServerResponse, IncomingMessage, and ClientRequest are properly instantiated with the new keyword.

​
Deprecation

Node.js deprecated calling HTTP constructors without the new keyword. Classes must be instantiated with new. See DEP0195 for more details.

​
Usage

Run this codemod with: 
npx codemod nodejs/http-classes-with-new

​
Before/After

  // import { IncomingMessage, ClientRequest } from "node:http";
  // const http = require("node:http");

- const message = http.OutgoingMessage();
+ const message = new http.OutgoingMessage();
- const response = http.ServerResponse(socket);
+ const response = new http.ServerResponse(socket);

- const incoming = IncomingMessage(socket);
+ const incoming = new IncomingMessage(socket);
- const request = ClientRequest(options);
+ const request = new ClientRequest(options);

​
What It Does

  • Adds new keyword before OutgoingMessage(), ServerResponse(), IncomingMessage(), and ClientRequest() calls
  • Works with both direct imports and namespace imports (e.g., http.OutgoingMessage())
  • Handles CommonJS and ESM module patterns

​
Affected Classes

The following HTTP classes are updated:
  • OutgoingMessage
  • ServerResponse
  • IncomingMessage
  • ClientRequest
Modern JavaScript requires all classes to be instantiated with the new keyword. This deprecation aligns Node.js HTTP classes with standard JavaScript class syntax.
