# example.js

This example illustrates how to filter the ContextModule results of `import()` statements. only `.js` files that don't
end in `.noimport.js` within the `templates` folder will be bundled.

```javascript
async function getTemplate(templateName) {
	try {
		let template = await import(
			/* webpackInclude: /\.js$/ */
			/* webpackExclude: /\.noimport\.js$/ */
			`./templates/${templateName}`
		);
		console.log(template);
	} catch(err) {
		console.error(err);
		return new Error(err);
	}
}

getTemplate("foo");
getTemplate("bar");
getTemplate("baz");
getTemplate("foo.noimport");
getTemplate("bar.noimport");
getTemplate("baz.noimport");
```

# templates/

- foo.js
- foo.noimport.js
- baz.js
- foo.noimport.js
- bar.js
- foo.noimport.js

All templates are of this pattern:

```javascript
var foo = "foo";

export default foo;
```

# dist/output.js
