I’m trying to follow this SuiteAnswers: <https://netsuite.custhelp.com/app/answers/detail/a_id/45054> but I can’t get the module to load correctly. Has anyone had success with this? I’m working on what’s shaping up to be a larger code base and I’d like to avoid loading larger libraries unless I actually need them.

if you require relative paths, then add the local require as a dependency
<https://github.com/amdjs/amdjs-api/blob/master/require.md|Local vs Global require>

Using absolute paths was the right answer. I’m still not sure if the return statement should be returning an instance of the module or a specific function.

I can get either to work at the level of the loader module, however I get `undefined` back from the `return new lib1();` statement.

i.e. `var lib = loader.newInstance('myType');` comes back `undefined` even though it’s clearly there in the loader method. I don’t get it…

```define({
	newInstance: function (type) {
		switch (type) {
			case 'makeKeyFile':
				require(['/SuiteApps/com.sample.app/lib/create_key'],
					function (createKey) {
						return createKey; 
						// also tried return new createKey();
					});
				break;
			case 'lib2':
				require(['/lib2'], function (lib2) {
					return new lib2();
				});
				break;
			default:
				return null;
		}
	}
});```

then, to call it from another file `var createKey = loader.newInstance('makeKeyFile');`

ive never seen an object used as an argument to a define function

that said, your function does not return anything for your 2 cases

nested return statements means you return from your inner function and return nothing in your outer function

in more normal amd environments, you would need to redesign this since the amd require is usually asynchronous

in suitescript, you can just set a variable in your outer function's closure scope and return that

Thanks for the context, that’s the part I was missing.

The NS environment is the hardest part of NS.

this was more of a javascript problem than a netsuite thing

So after lots of frustration I explored another route and tried this alternative and it seems to work: <https://www.typescriptlang.org/docs/handbook/release-notes/typescript-2-4.html#dynamic-import-expressions>.
