When compiling to ES5, TypeScript fails to remove imports

I am working on a TypeScript file that utilizes the moment library, and I need to import moment for it to compile properly. However, after compilation, the import line is still present in the compiled file, which is causing issues on my web page.

Here is an excerpt from my tsconfig file:


{
    "compileOnSave": true,
        "compilerOptions": {
        "lib": [
            "es2015",
            "dom"
        ],
            "module": "es2015",
             "moduleResolution": "node",
             "noEmitOnError": true,
             "outDir": "Assets/Scripts/lib",
             "pretty": true,
             "removeComments": true,
             "rootDir": "tsSrc",
             "target": "es5",
             "sourceMap": true
    },
    "exclude": [
        "node_modules",
        "tsSrc/typescript-definitions"
    ]
}

Below is an example of how moment is being used in the code:


/// <reference path="../../../node_modules/moment/moment.d.ts" />
import * as moment from "moment";

console.log(moment().format("M/D/YYYY h:mm a"));

Answer №1

By setting "module": "es2015", you are indicating that the import statements follow ES2015 module syntax. Make sure to specify which specific module loader you are using, such as amd or commonjs.
