No relation to TypeScript 4.0

Overview

ember-cli-typescript no longer manages your Babel configuration, because ember-cli-babel does. This is an early step toward officially supporting TS across the Ember ecosystem. It also means that we now use Babel’s default configuration, which also comes with a small change to align better with the JavaScript spec around class fields.

For most cases, you won’t notice the difference, but if you were previously using TypeScript’s constructor property shorthand to define default values and using those values in a class field initializer, like this—

class Demo {
  constructor(public name = '') {}
  public nameLen = this.name.length;
}

—you will find that the initializer now fails. This is because the spec requires that class field initializers run before anything in the class constructor’s body except a super call, and TS’s custom syntax here is not part of the spec, and Babel therefore runs it after all other class field initializers.

This particular pattern was always a refactoring hazard: class field initializers should not refer to this because they can be broken by unrelated changes in surprising ways. This particular code will now not work at all, so you will need to migrate away from it. You can replace it with this code instead:

class Demo {
  public nameLen: number;
</tr></table>
