Enhancing a UMD module definition with TypeScript 2: A step-by-step guide

Currently, I am in the process of creating TypeScript definition files for two libraries that are meant to be used with the new @types approach. Both libraries adhere to the UMD pattern, allowing them to be consumed either as modules or by referencing them in a <script> tag.

The first library was relatively easy to define as consumption through both methods would look like this:

import { AccessManager } from 'twilio-common';
const manager = new AccessManager('XXXXXXXX');

or

const manager = new Twilio.AccessManager('XXXXXXXX');

To handle this dual consumption scenario, I utilized the new export as namespace feature introduced in TypeScript 2:

import { Promise } from 'es6-promise';

export as namespace Twilio;

export class AccessManager {
  constructor(initialToken: string);
  identity: string | null;
  // omitted
}

Now, addressing the second library is where things get a bit more complex and brings me here for assistance.

Consumption via module:

import { AccessManager } from 'twilio-common';
import { Client } from 'twilio-ip-messaging';

const manager = new AccessManager('XXXXXXXX');
const client = new Client(manager);

Consumption via <script> tag:

const manager = new Twilio.AccessManager('XXXXXXXX');
const client = new Twilio.IPMessaging.Client('XXXXXXXX');

As seen, the contents of the second definition file should be exported using a statement like:

export as namespace Twilio.IPMessaging;

Unfortunately, this solution does not work. In light of this challenge, I am seeking advice on StackOverflow.

Thank you in advance!

Answer №1

An alternative approach is to create a specialized Twilio namespace that includes a nested IPMessaging sub-namespace, and then expose "Twilio" as the overarching global namespace.

This design allows for Twilio to be easily accessed as an importable entity within modules.
