Seamless switching between online (CouchDB) and offline (PouchDB) authentication.

WARNING: This plug-in stores password hashes in a local PouchDB. In for example internet cafes, this is not a smart thing to do. In your app, you should include a checkbox 'I trust this computer' and only use pouchdb-seamless-auth when it is checked. Otherwise, you can fall back to pouchdb-auth. This functionality might be implemented as part of the plug-in in the future.


NodeJS package name: pouchdb-seamless-auth

Browser object name: window.SeamlessAuth

This plug-in provides a convenience layer on top of the PouchDB Auth plug-in. By default, it users a local database named _users as backend for its log in, log out and get session actions. But, when you set a remote database, that local database is synced with the given database. In other words, it allows you to let your user log in one time using the remote database, and from that moment on you can also the session functions while offline! Very handy when using a per-user database set up that PouchDB syncs.

Instead of passing this plug-in to the PouchDB.plugin() function, install it like this:

``javascript //NodeJS require("pouchdb-seamless-auth")(PouchDB)

//Browser SeamlessAuth(PouchDB) ``

After that is finished (a promise is returned to help determine when that is), all functions documented below are available on the PouchDB object.

PouchDB.setSeamlessAuthRemoteDB(remoteName[, remoteOptions[, callback]])

Set a remote database to be seamlessly synced to.


  • string remoteName: The url to the remote database. Passed to the PouchDB constructor as the first argument.
  • object remoteOptions: Options to pass on to the PouchDB constructor as its second argument.
  • function callback: An alternative for the returned promise.

Returns: a promise, which resolves to nothing when the remote database is completely set up.


A synchronous function. Undos what PouchDB.setSeamlessAuthRemoteDB() did.

Returns: nothing.

PouchDB.seamlessSession([opts[, callback]])

See pouchdb-auth's db.session().

PouchDB.seamlessLogIn(username, password, [opts[, callback]])

See pouchdb-auth's db.logIn().

PouchDB.seamlessLogOut([opts[, callback]])

See pouchdb-auth's db.logOut().

PouchDB.seamlessSignUp(username, password, [opts[, callback]])

See pouchdb-auth's db.signUp().


Used to invalidate the cache manually.

This is a synchronous function. Because an application might call PouchDB.seamlessSession() a lot of times, that method is cached. For most of the time, you don't have to worry about that, because log in, log out and sign up all invalidate that cache, making it pretty much unnoticable. There is one known exception: when changing the user document in _users manually. Call this to invalidate the cache when you do that.

Returns: nothing.
