add databases interface to IDBFactory

indexDB types

Suggestion

I would like to add to the IDBFactory interface the databases function

Use Cases

I was encountering an issue when I wanted to delete all the existing indexedDBs on my client application. For instance, if the user signs out, I want delete all the data and I don’t want to hard code the name of the databases in the code. So I did something like this:

    const dbKeys = await (window.indexedDB as any).databases();
    for (let key of dbKeys) {
      indexedDB.deleteDatabase(key.name);
    }

Examples

in lib.dom.d.ts:

interface IDBFactory {
...
databases(name: string): IDBDatabase[];
}

interface IDBDatabase {
name: string;
version: number;
}

Checklist

My suggestion meets these guidelines:

• This wouldn’t be a breaking change in existing TypeScript/JavaScript code
• This wouldn’t change the runtime behavior of existing JavaScript code
• This could be implemented without emitting different JS based on the types of the expressions
• This isn’t a runtime feature (e.g. library functionality, non-ECMAScript syntax with JavaScript output, etc.)
• This feature would agree with the rest of TypeScript’s Design Goals.

Why do you have to create an issue in the w3c repo? Editor’s Draft for Indexed Database API 3.0 (which includes implementation of IDBFactory#databases) already exists. https://w3c.github.io/IndexedDB/#factory-interface

The only thing we have to do is to just wait for the Draft to be published as Candidate recommendation or the browsers implementation(FireFox and safari). Or, if the TS team think this feature can be added to the lib.dom.d.ts even it is in Draft stage.
