Unable to locate the name 'X' despite importing the name directly above

I'm a little confused about the situation at hand. The name is clearly mentioned right above.

Displayed below is the content of storage-backend.interface.ts:

export declare interface StorageBackend extends Storage { }

Could you clarify what's going on here?

Answer №1

When working with provider tokens, it's important to note that interfaces cannot be used since they do not exist at runtime. Instead, consider using a class, a string, or the OpqueToken.

If you encounter this issue, you may want to try the following approach:

export interface StorageBackend extends Storage { }

The use of the declare keyword is typically reserved for "declaring" elements in definition files (.d.ts), rather than directly in a TypeScript module.
