Delete all indexedDB databases

delete-databases.js

// Credit to @steobrien from https://gist.github.com/rmehner/b9a41d9f659c9b1c3340#gistcomment-2940034
// for modern browsers, this works:
const dbs = await window.indexedDB.databases()
dbs.forEach(db => { window.indexedDB.deleteDatabase(db.name) })

// for older browsers, have a look at previous revisions of this gist.

Remember to wrap the execution in an async function.

(async () => {
    const dbs = await window.indexedDB.databases();
    dbs.forEach(db => { window.indexedDB.deleteDatabase(db.name) });
})();

This works fine for me on Safari. Note that you may not see the effect immediately on the dev tool until you close the browser window and open it again.
