Can I Pass Options to ES6 Module Imports?

Passing Options to ES6 Module Imports

In the realm of ES6 module imports, the question arises: Can we pass options to these modules? The answer lies in understanding the intrinsic properties and limitations of ES6 import statements.

Conventional Approach

Traditionally, in CommonJS, we could pass options by invoking the required module like so:

var x = require('module')(someoptions);

ES6 Module Equivalents

However, in ES6, there isn't a direct equivalent for such invocations. ES6 imports focus on importing a module rather than creating an instance.

Default Exports as a Solution

To achieve a similar functionality, we can utilize default exports. The module we want to import can define a default function:

// module.js
export default function(options) {
    return {
        // actual module
    }
}

In our main module, we can import this module and invoke it, providing the options:

// main.js
import m from 'module';
var x = m(someoptions);

Exploring Alternative Approaches

Depending on the module loader you're using, you may have additional options. For instance, with module loaders that support monadic promises, you could use:

System.import('module').ap(someoptions).then(function(x) { … });

Conclusion

Unfortunately, there isn't a straightforward way to pass options to ES6 imports using a single import statement. However, by utilizing default exports or leveraging module loader features, we can achieve similar functionalities.
