I am encountering difficulties while attempting to import Typescript files. Upon compiling them into Javascript, I am faced with errors in the web browser, specifically the issue of "exports is not defined"

When I run TodoAppUI.js:15, I get an error saying "Uncaught ReferenceError: exports is not defined"

In all my classes, I use the export keyword. For example:

export class mysclass {
public constructor(){}
}

Even though I have the proper syntax for importing, it still doesn't work

import TodoAppUI = require("./TodoAppUI");

This is how my configuration file looks like:

{


        "compilerOptions": {
            "module": "commonjs",
            "noImplicitAny": true,
            "removeComments": true,
            "preserveConstEnums": true,
            "sourceMap": true,
            "target": "es5"

        }, 
    "files": [
        "TodoApp.ts",
        "BaseService.ts",
        "TodoAppUI.ts"


    ]

}

The following code snippet is the one causing the issue:

Object.defineProperty(exports, "__esModule", { value: true });

Answer №1

When you include 'module: 'commonjs'' in your configuration file, the compiler will compile your code into a 'commonjs' module format. This means you will access modules using syntax like <code>const TodoAppUI = require("./TodoAppUI")
. If you prefer to use the 'import' syntax, simply update your config file by changing module: 'ES6'.
