Creating a Typescript project that compiles to UMD format, however, encountering the challenge of

I am trying to convert my index.ts file into a UMD index.js so that I can use it with a <script> tag. Here is the TypeScript configuration I am using:

{
  "compilerOptions": {
    "outDir": "dist",
    "declaration": true,
    "module": "UMD",
    "target": "ES6",
    "moduleResolution": "node",
    "strict": true
  },
  "include": ["src/**/*.ts", "tests/**/*.ts"]
}

When I compile the file, the generated index.js is not as expected. It seems to be creating multiple files instead of one unique file. Here is the output:

(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", "./embedTypes/container", "./embedTypes/popup", "./embedTypes/chat"], factory);
    }
})(function (require, exports) {
    "use strict";
    Object.defineProperty(exports, "__esModule", { value: true });
    const container_1 = require("./embedTypes/container");
    const popup_1 = require("./embedTypes/popup");
    const chat_1 = require("./embedTypes/chat");
    const Typebot = {
        initContainer: container_1.initContainer,
        initPopup: popup_1.initPopup,
        initBubble: chat_1.initBubble,
    };
    exports.default = Typebot;
});

I am not sure what I am missing in the configuration. Any help or suggestions would be greatly appreciated. Thank you!

Answer №1

While the TypeScript compiler doesn't bundle files, it simply compiles each file independently. My suggestion would be to consider using Webpack due to its versatility and user-friendly interface. However, if you are planning to dive into frameworks like Angular or React, which offer this feature out-of-the-box, you might want to explore other alternatives such as browserify, grunt, gulp, babel, parcel, and more.
