API

use(dbName)

return a database provider instance. once the provider connected, it can be used anywhere.

provider.connect(options, callback)

connect a remote RPC limbo server and fetch model and methods from server.

NOTICE: since the connect would only be done once, models and methods would only be fetched once. That means if the server changed schemas and restart, client would not fetch again.

NOTICE2: tls Options only for limbo#dev and it's recommended.

• options:
  • url(String): (tcp|tls)://[host]:[port], e.g. tcp://localhost:5700
  • tls(Object): if url protocal is tls, options should has tls. also see tls Options
• callback(Function): callback when connected or fail

providermodel

return the remote rpc model of limbo. It is more like mongoose model.

Notice1: since it is a remote model, model.find is a simulated method to fetch the document. and the document IS NOT a real document, it is toJSONed.

So you CAN NOT use document as a mongoose document to call something like save method. Use db.model.update() instead. To be honest, it is safer to call update than save for knowing what you have done to the document.
