TypeScript type information for Node require

Question

I have a Node server created as:

function createHttpServer(app) {
    var http = require('http');
    var server = http.createServer(app);
    return server;
}

I am in the process of migrating our .js code into .ts code and I notice that when the extension is .js, I get type information for createServer. However, when I switch to .ts it becomes any, so I struggle with the correct typings.

This is what my tsconfig.json file looks like:

{
    "compileOnSave": false,
    "compilerOptions": {
        "allowJs": true,
        "outDir": "./out-tsc",
        "sourceMap": true,
        "declaration": false,
        "moduleResolution": "node",
        "emitDecoratorMetadata": true,
        "experimentalDecorators": true,
        "target": "es6",
        "types": [
            "node"
        ],
        "lib": ["es6"],
        "module": "commonjs",
        "pretty": true,
        "allowSyntheticDefaultImports": true
    }
}

Why, despite the node types, do I get any instead of the correct type information?

If you see the type within your create server function, is it correct? — Vitor Ribeiro

Try using import instead of require

import * as http from "http";

function createHttpServer(app) {
  // var http = require("http");
  var server = http.createServer(app);
  return server;
}
