What is the best way to integrate Greensock CustomEase with TypeScript?

Currently, I am developing a game using Typescript with PixiJS and GreenSock (or is it GSAP?) for handling all the tweening. I recently encountered a situation where I needed to implement some custom easing using cubic-bezier curves. GreenSock provides a Customease file which can be obtained after creating an account, and that's exactly what I did. However, I faced a roadblock when I realized that the file lacks a Typescript definition.

Despite my efforts, I am clueless about how to integrate this CustomEase.js file into my application without a type definition file. I attempted to utilize a solution from https://github.com/bigp/gsap-customease, but unfortunately, it proved to be ineffective. It appears to be outdated and irrelevant to my requirements.

Essentially, I am seeking guidance on the proper approach to incorporating the CustomEase.js file into my Typescript-based application. Any assistance or insights would be greatly appreciated.

Answer №1

There are numerous ways to accomplish this task, each with its own set of implications. I personally find all of them to be valuable in various scenarios.

Without knowledge of the file's basic structure, whether it is a module or global, and its level of complexity, it is challenging to determine the most appropriate approach. However, here are a few options (although there are many more available):

  1. Enable --allowJs ("allowJs": true in tsconfig compilerOptions) to directly consume JavaScript sources within integrated TypeScript source without requiring declarations. (ES Next syntax will be transpiled automatically)

  2. Manually create a declaration file.

  3. Automatically generate a declaration file (also a good starting point for a manual declaration) using the following steps:

    • Copy CustomEase.js

    • Rename it to CustomEase.ts

    • Run 

      tsc --declaration ./CustomEase.ts
      as a one-time process

    • Delete CustomEase.ts

    • Keep the generated CustomEase.d.ts declaration file alongside the JavaScript file

  4. Rename the file to CustomEase.ts and refrain from making any further changes. Although you may encounter type errors, if the JavaScript code is valid, TypeScript will handle it appropriately during consumption and transpilation.

  5. (Not recommended) For extremely simple file structures, such as one that solely defines a global variable like customEase, you could use the following declaration whenever needed:

    declare const customEase: any;

    (Please note that this is just an example and may not apply to your specific file)

If either method 2 or 3 prove to be effective, consider sending the modifications back to the maintainers for inclusion in future releases.
