tslib 4.3 __classPrivateFieldGet

🕗 Version & Regression Information

4.3.0-dev.20210401

• I was unable to test this on prior versions because this is related to a new feature in 4.3

⏯ Playground Link

I'm unable to provide a playground link, as importHelpers is not reflecting in the playground, when selected.

💻 Code

/**
 * Module utils
 */
export class ModuleUtil {

  static #handlers: ModuleHandler[] = [];
  /**
   * Add module post processor (post-load)
   *
   * @param handler The code to run on post module load
   */
  static addHandler(handler: ModuleHandler) {
    this.#handlers.push(handler);
  }

🙁 Actual behavior

The typescript compiler is showing the below error:

And I can see in tslib 2.1 that there is no support for more than 2 parameters for __classPrivateFieldGet. It looks like there is no compatible tslib for the 4.3.0 beta.

🙂 Expected behavior

importHelpers should be able to work with 4.3.

@rbuckton can you port the helper changes and additions over to tslib? I'll also need some help figuring out versioning there.

[arciisine]

Looks like a PR has already been merged to update the helpers: microsoft/tslib#146.

@DanielRosenwasser As far as tslib is concerned, the tslib change is backwards compatible so we can publish as a minor or patch version.

[DanielRosenwasser]

tslib 2.2.0 should fix this.
