Universal Module Identifier

Universal Module Identifier

I'm trying to figure out how to add a namespace declaration to my JavaScript bundle.

My typescript class is located in myclass.ts

export class MyClass{
...
}

I am using this class in other files as well

export {MyClass} from "myclass"
...
let a: MyClass = new MyClass();

I compile it using VS Code and use Grunt to automate concatenating different files and minifying them with Terser.

Everything works fine, but I want to add a namespace before my class when using it in JS

<script src="mylib.min.js"></script>
...
var a = new MYLIB.MyClass();

At what point in the process should I introduce the "MYLIB" namespace? I would like to continue working with the export/import pattern without including the namespace or module name inside the TS file.

Is there a Grunt plugin that can help with this? I have been unable to find clear information or samples on this topic.

Answer №1

Your approach involves a mix of javascript and typescript, which may seem confusing as typically code is written using one language exclusively. In javascript, there is no built-in concept of namespacing, so attempting to call new MYLIB.MyClass() will not work. Typescript, however, does support namespaces, allowing for the use of syntax like https://www.typescriptlang.org/docs/handbook/namespaces.html.

For an alternative method in pure javascript that somewhat mimics namespaces, refer to this answer. Keep in mind that in javascript, a "namespace" is essentially just an object, so calling new namespace.myClass() won't function as expected since class definitions cannot reside directly on objects.

No simple solution was found using Grunt alone, so I switched to webpack and incorporated the following code:

output: {
    library: 'MYLIB',
    libraryTarget: 'var',
    filename: '[name].' + config.version + '.js' ,
    path: path.resolve(__dirname, 'dist'),
}

I realize that webpack and grunt are not typically used together, but it is possible to make them work in conjunction. I may also explore using webpack with gulp. Thank you to all readers and @see shaper for taking the time to provide an answer. Stay safe at home.
