After updating my Typescript definitions with the latest version available today, I noticed a change in the angular.d.ts file regarding the definition of scope within the IDirective interface:
interface IDirective {
...
scope?: boolean | {[boundProperty: string]: string};
...
}
Incorporating this change into my directive implementation (with placeholder names and extraneous code removed) resulted in the following code:
export class MyDirective implements angular.IDirective {
scope = {
a: "&",
b: "@?",
c: "=?",
d: "=?",
e: "@?",
}
}
However, upon compilation, I encountered the following error:
Error Class 'MyDirective' incorrectly implements interface 'IDirective'. Types of property 'scope' are incompatible.
Type '{ a: string; b: string; c: string; d: string; e: string; }' is not assignable to type 'boolean | { [boundProperty: string]: string; }'.
Type '{ a: string; b: string; c: string; d: string; e: string; }' is not assignable to type '{ [boundProperty: string]: string; }'.
Index signature is missing in type '{ a: string; b: string; c: string; d: string; e: string; }'.
This discrepancy has left me puzzled. The properties being assigned are strings, which aligns with the expected format of
{ [boundProperty: string]: string; }
