Sets the module system for the program.

See the Modules reference page for more information. You very likely want “CommonJS” for node projects.

Changing module affects moduleResolution which also has a reference page.

Here’s some example output for this file:

// @filename: index.ts
import { valueOfPi } from "./constants";


export const twoPi = valueOfPi * 2;

CommonJS

"use strict";
Object.defineProperty(exports, "__esModule", { value: true });
exports.twoPi = void 0;
const constants_1 = require("./constants");
exports.twoPi = constants_1.valueOfPi * 2;

UMD

(function (factory) {
    if (typeof module === "object" && typeof module.exports === "object") {
        var v = factory(require, exports);
        if (v !== undefined) module.exports = v;
    }
    else if (typeof define === "function" && define.amd) {
        define(["require", "exports", "./constants"], factory);
    }
})(function (require, exports) {
    "use strict";
    Object.defineProperty(exports, "__esModule", { value: true });
    exports.twoPi = void 0;
    const constants_1 = require("./constants");
    exports.twoPi = constants_1.valueOfPi * 2;
});

AMD

define(["require", "exports", "./constants"], function (require, exports, constants_1) {
    "use strict";
    Object.defineProperty(exports, "__esModule", { value: true });
    exports.twoPi = void 0;
    exports.twoPi = constants_1.valueOfPi * 2;
});

System

System.register(["./constants"], function (exports_1, context_1) {
    "use strict";
    var constants_1, twoPi;
    var __moduleName = context_1 && context_1.id;
    return {
        setters: [
            function (constants_1_1) {
                constants_1 = constants_1_1;
            }
        ],
        execute: function () {
            exports_1("twoPi", twoPi = constants_1.valueOfPi * 2);
        }
    };
});

ESNext

import { valueOfPi } from "./constants";
export const twoPi = valueOfPi * 2;

ES2020

import { valueOfPi } from "./constants";
export const twoPi = valueOfPi * 2;

None

"use strict";
Object.defineProperty(exports, "__esModule", { value: true });
exports.twoPi = void 0;
const constants_1 = require("./constants");
exports.twoPi = constants_1.valueOfPi * 2;
