Best practice for error parsing

[alfille]

Issue

How to parse the "catch" objects?

Info

• Environment: Browser
• Platform: All
• Adapter: probably indexeddb
• Server: CouchDB

Reproduce

Briefly, in my application (https://emissionsystem.org) which uses straight javascript, pouchdb, and a couchdb server (albeit with SSL), I try to follow good practice and use a catch clause in all my pouchdb promises. Example:

db.get("patient").
.then(.....)
.catch(err => process(err))

Is there a consistent format for "err"? Sometimes I see err.message for a text description, but I'm not sure it's a pervasive pattern.

My hope is to provide useful feedback to users and make my application more robust.

Heya, while PouchDB aims to be consistent, we as a project cannot promise we won’t surface error message from subsystems that aren’t adjusted accordingly.
