We still use couchdb & pouchdb only for syncing data for our salesmen app.

It's an offline first PWA (Salesman need to make an order even if offline).

And pouchdb make it easier because we don't have to care about indexeddb, leveldb or whatever of users browser's db.

So its a single codebase for serving web, ios and android.

Its great for sync but less then good for other uses
