PouchDB with Ionic 3 - Which storage system should I use?

OK:slight_smile:

1. Ionic Storage:
   Pros:

• very simple get/set API
• configurable, adapters etc
• part of Ionic offering, which hopefully means good support
• small size (8kb?)
  Cons:
• almost no control over db, not sure you can index data etc
• syncing data with server needs custom code (we wrote it)
• no bulk type operations (does have .forEach method though)
• supports storage of blobs but not as attachments, both dbs have issues with binary data I think. We saw some behaviors and super hard to triage issues when we stored binaries locally. Once we removed those - issues were gone…

2. PouchDB
   Pros:

• nice syncing mechanism with other couchDB (although couchDB is considered to be slow, for lazy replication its good)
• bulk operations, built-in conflict resolution
• extensive API, you can do a lot of things, indexes etc
  Cons:
• more complex API to work with. For a put you almost always need to read document and use its revision to store it back etc
• basically complexity led to more bugs in our case.
