Typescript build error when using package

[jbellos]

npm install @duckdb/[email protected]
using typescript 4.6.4

create a new class:

import { DuckDBInstance } from '@duckdb/node-api';

export class DuckDbPostalAddressRepository {
    private _instance?: DuckDBInstance;

    private async _setupDataSource(): Promise<void> {
        if (!this._instance) {
            this._instance = await DuckDBInstance.create(':memory:');
        }
    }
}

compile with npm run tsc

../node_modules/@duckdb/node-api/lib/DuckDBLogicalType.d.ts:16:9 - error TS2380: The return type of a 'get' accessor must be assignable to its 'set' accessor type

If you need my tsconfig file let me know.

Changing this to get alias(): string; fixes the build issue, but I've no idea if that's what you want to do here :)

I believe this restriction was lifted in TypeScript 5.1. Can you upgrade, or do you need to stick with an older version for some reason?

[jraymakers]

It's easy to support this case by expanding the accepted types for this function, so I'm doing that: #121

[jraymakers]

The fix is merged and will go out the next time I do a release. Since DuckDB 1.2.0 is coming out very soon, I'll likely wait for that.

Fixed in 1.1.3-alpha.11.
