TypeScript 4.3.1-rc error on resolved store name

[brunnerh]

Not sure if this is worth looking into as TS 4.3 has not been released yet, but using this version causes store name parameters to not be resolved correctly.

E.g.

import { openDB, DBSchema } from 'idb';

async function doDatabaseStuff()
{
	const db = await openDB<DB>('documents', 1, {
		upgrade(db, oldVersion, newVersion, transaction)
		{
			// Argument of type 'string' is not assignable to parameter of type 'never'. ts(2345)
			db.createObjectStore('documents', { keyPath: 'id' });
		}
	});
}

interface DB extends DBSchema
{
	documents: {
		value: {
			id: string,
			text: string,
		}
		key: string,
	},
};

package.json:

{
	"dependencies": {
		"idb": "6.0.0",
		"typescript": "4.3.1-rc"
	}
}

Cheers. I can recreate this issue.

Fixed in e3c76a5, and published as 6.1.0. Thanks for catching this!

I think this might be a TypeScript bug (and I'll file an issue with them), but I'm happy with the change here.
